生化末端 沒(méi)有影響，何況少量的鐵鹽能夠?qū)hosphorus removal agent for road treatment is a kind of material for coagulation and turbidity removal of urban water source and phosphorus removal. It can reach the intent of deep dephosphorization at the same time of coagulation and turbidity removal of urban water source.
Thus, the phosphorus content in treated drinking water can be reduced to below the threshold value, without changing the original water treatment process, without adding large water treatment structures, which is simple, economical and practical, and can achieve remarkable social and economic benefits.
The amount of phosphorus removal agent used in river regulation will not cause adverse effects. After all, iron is also a trace element needed for microbial growth. However, if the dosage is too large, the sludge activity will be affected. There are still doubts about environmental protection and communication.
There is no effect on the biochemical end, let alone a small amount of iron salts.
懸浮物上漂
1、操作不當(dāng)，有的是不專(zhuān)業(yè)的人員在實(shí)驗(yàn)中運(yùn)用了不當(dāng)手法，加入聚合氯化鋁后，攪拌過(guò)急過(guò)慢都不行，初次實(shí)驗(yàn)，要有專(zhuān)業(yè)的水處理師從旁協(xié)助，這是很重要的一點(diǎn)。
2、加聚合硫酸鐵的量沒(méi)有控制好，（加藥過(guò)多或過(guò)少）這種情況，最容易出現(xiàn)懸浮物上漂。
使用前，將本產(chǎn)品按一定濃度（10-30%）投入溶礬池，注入自來(lái)水?dāng)嚢枋怪浞炙?，靜置至呈紅棕色液體，再兌水稀釋到所需濃度投加混凝。水廠亦可配成2-5%直接投加，工業(yè)廢水處理直接配 成5-10%投加。 b、投加量的確定，根據(jù)原水性質(zhì)可通過(guò)生產(chǎn)調(diào)試或燒杯實(shí)驗(yàn)視礬花形成適量而定，制水廠可以原用的其它藥劑量作為參考，在同等條件下本產(chǎn)品與固體聚合氯化鋁用量大體相當(dāng)，是固體硫酸鋁用量的 1/3-1/4。如果原用的是液體產(chǎn)品，可根據(jù)相應(yīng)藥劑濃度計(jì)算酌定。大致按重量比1:3而定。

污水處理1. Improper operation, some non-professional personnel in the experiment used improper techniques, adding polyaluminium chloride, stirring too fast or too slow can not, the first experiment, there must be professional water treatment assistant, this is a very important point.
2. The amount of polyferric sulfate added is not well controlled (too much or too little dosage). In this case, suspended solids are most likely to float.
Before use, the product was put into the alum bath at a certain concentration (10-30%) and stirred with tap water to make it fully hydrolyzed. The product was put into a red-brown liquid and diluted with water until the required concentration was added and coagulated. Waterworks can also be added 2-5% directly, and industrial wastewater treatment can be added 5-10%. B. The determination of dosage depends on the proper amount of alum bed by production debugging or beaker experiment according to the nature of raw water. The other dosage used in water plant can be used as reference. Under the same conditions, the dosage of this product is approximaby equal to that of solid polyaluminium chloride, which is 1/3-1/4 of that of solid aluminium sulfate. If the original liquid product is used, it can be calculated according to the concentration of the corresponding agent. It depends roughly on the weight ratio of 1:3.

3、加聚合硫酸鐵的量對(duì)了，但是廢水的PH值不對(duì)，沒(méi)有在相應(yīng)藥劑的PH范圍。適應(yīng)水體PH值范圍寬為4-11，PH值范圍為6-9，凈化后原水的PH值與總堿度變化幅度小
4、使用凈水產(chǎn)品的型號(hào)不對(duì)，根據(jù)污水的特點(diǎn)，選擇適合自己污水特征的凈水劑，如：聚合氯化鋁、聚氯化鋁、聚合氯化鋁鐵、氯化鋁、噴霧式聚合氯化鋁、白色聚合氯化鋁等等，聽(tīng)從專(zhuān)業(yè)水處理師的指導(dǎo)意見(jiàn)，他們給的意見(jiàn)都是專(zhuān)業(yè)性的。

5、最后一點(diǎn)要考慮的就是，你所使用的聚合硫酸鐵，質(zhì)量是否達(dá)標(biāo)，聚合硫酸鐵的各項(xiàng)指標(biāo)是否符標(biāo)準(zhǔn)。
現(xiàn)在市面上聚合硫酸鐵的質(zhì)量參差不齊，相對(duì)于質(zhì)量好一些的聚合硫酸鐵在使用過(guò)程中，出現(xiàn)懸浮物的幾率會(huì)很低的，好一些的聚合硫酸鐵幾乎是沒(méi)有水不溶物的，所以產(chǎn)品質(zhì)量也是非常重要。微生物活性有促進(jìn)作用，就是出水色度有影響
將化學(xué)除磷劑投加于生化池的后面，這樣便可以完全避免水中多種物質(zhì)與除磷劑發(fā)生反應(yīng),消耗藥劑用量.且不會(huì)降低生化池的進(jìn)水有機(jī)碳濃度，影響微生物的脫氮除磷效果。同時(shí)還可避免過(guò)多投加除磷劑，也會(huì)使殘余的藥劑進(jìn)入生化系統(tǒng)中，對(duì)微生物生長(zhǎng)造成影響。
將除磷絮凝劑投加于好氧池的出水口端，二沉池的前面投加除磷劑則可以大量減少除磷藥劑的使用量，這是廢水在生化處理的過(guò)程中已去除水中大部分磷，并將偏磷、有機(jī)磷轉(zhuǎn)化為可通過(guò)混凝處理的正磷，大大提高除磷效果和減少除磷劑投加量，減少污泥產(chǎn)量、減少污泥中的磷含量。 所以，化學(xué)除磷藥劑一般投加于生化后，二沉池前，節(jié)省廢水除磷成本和提高達(dá)標(biāo)率。?

The suitable range of PH value is 4-11, and the optimum range of PH value is 6-9. After purification, the change range of PH value and total alkalinity of raw water is small.

Polyferric sulfate
5. The last point to consider is whether the quality of the polyferric sulfate you use meets the national standards, and whether the various indicators of the polyferric sulfate meet the national standards.
At present, the quality of polyferric sulfate is uneven in the market. Compared with the better quality of Polyferric sulfate, the probability of suspended solids will be very low. The better polyferric sulfate has almost no water insoluble solids, so the quality of products is also very important. Microbial activity has a promotive effect, that is, effluent color has an impact.
Adding chemical Dephosphorizer to the back of biochemical pond can compleby avoid the reb between various substances in water and dephosphorizer, consume the amount of reagent, and will not reduce the concentration of organic carbon in the influent of biochemical pond, affecting the effect of nitrogen and phosphorus removal by microorganisms. At the same time, it can avoid excessive dosage of phosphorus removal agents, and also make the residual agents into the biochemical system, which will affect the growth of microorganisms.
Adding phosphorus removal flocculant to the outlet of aerobic tank and phosphorus removal agent in front of secondary sedimentation tank can greatly reduce the use of phosphorus removal agent. This is because most phosphorus in wastewater has been removed in the process of biochemical treatment, and phosphorus migration and organic phosphorus are converted into positive phosphorus which can be treated by coagulation, which greatly improves the effect of phosphorus removal and improves the efficiency of phosphorus removal. Reduce the dosage of phosphorus removal agent, reduce sludge production, reduce phosphorus content in sludge. Therefore, chemical phosphorus removal agents are generally added to the biochemical process, before the secondary sedimentation tank, to save the cost of phosphorus removal from wastewater and improve the rate of reaching the standard. ?
When in use, the product can be directly added or participated in the dissolving tank, the concentration of which is 10-20%, mixed and pumped into the reb tank. The product is suitable for a wide range of pH values, especially in acidic conditions. Its application amount is about 100-1000 ppm (i.e. 0.1-1 kg/ton wastewater). According to the different content of phosphate in wastewater, its dosage is different. The detailed dosage is generally determined by experiments.
During the experiment, a certain amount of raw water was taken and the product (such as 500 ppm) was added. The pH value of the wastewater was adjusted to 7-8. www.hnldscl.com participated in the flocculation and deb of a few PAM. The supernatant was filtered to determine the phosphorus content.

陰離子聚丙烯酰胺依據(jù)不同用處和用戶(hù)對(duì)產(chǎn)品性能的央求，可選用不同分子量運(yùn)用。
在工業(yè)廢水處置中，特別是關(guān)于懸浮顆粒、較粗、濃度高、粒子帶陽(yáng)電荷，水的PH值為中性工堿性的污水如鋼鐵廠廢水，電鍍廠廢水，冶金廢水，洗煤廢水等污水處置效果很好。
在飲用水處置。我國(guó)很多自來(lái)水廠的水源自江河泥少及礦物質(zhì)含量高，比擬混濁，雖經(jīng)過(guò)沉淀處置，但仍達(dá)不到央求，需求投加絮凝劑，才干使水質(zhì)變清，很多自來(lái)水廠采用無(wú)機(jī)絮凝劑，但投加量大，構(gòu)成污泥量增大效果不好，采用陰離子聚丙烯酰胺作絮凝劑，投加量是無(wú)機(jī)絮凝的50分之一但效果是無(wú)機(jī)絮凝劑的幾倍至幾十倍，特別是我公司消費(fèi)的聚丙烯酰胺，剩余單體已抵達(dá)食品級(jí)(小于0.05%)，接近國(guó)外先進(jìn)程度，對(duì)處置飲用水更為合適，關(guān)于有機(jī)物污染嚴(yán)重的江河水和陰離子聚丙烯酰胺配合運(yùn)用效果更好。
聚丙烯酰胺用作淀粉廠及酒精廠的流失淀粉及酒糟的回收。往常很多淀粉廠排出的廢水內(nèi)淀粉很高，排放之后影響環(huán)境，糜費(fèi)資源，投加PAM，使淀粉沉淀，沉淀物經(jīng)壓濾機(jī)壓濾變成餅類(lèi)可作飼料，酒精廠大量的酒糟就是采用這種工藝加工的，黑龍江某酒精廠就是聚丙烯酰胺作絮凝劑，對(duì)酒糟中止回收的而且獲得了很大的經(jīng)濟(jì)效益。

The process is as follows: catalyst: catalytic hydration CH2 = CHCN + H2 humidity CH2 = CHCONH2 polymerization nCH2 = CHCONH2 - initiator - CH2CHCONH2
Industrial uses of polyacrylamide: Polyacrylamide (PAM) has high molecular weight, good water solubility, adjustable molecular weight, and can introduce various ionic groups to obtain specific properties. Low molecular weight is an effective additive or stabilizer for dispersing materials. High molecular weight is an important flocculant. It can produce hydrophilic and water-insoluble gel, which has good adhesion to many groups of surface and dissolved substances. Because of the above properties, PAM is widely used in flocculation, thickening, drag reduction, glue imitation, bonding, scale inhibition and other fields.
Anionic polyacrylamide can be used in different molecular weights according to different uses and user's requirements for product perbance.
In industrial wastewater treatment, especially for suspended particles, coarser, high concentration, positive charged particles, neutral and alkaline wastewater such as iron and steel plant wastewater, electroplating plant wastewater, bllurgical wastewater, coal washing wastewater and other wastewater treatment effect is very good.
In drinking water treatment. The water source of many Waterworks in our country is low in mud and high in mineral content, which is turbid. Although it has been treated by precipitation, it still can not meet the requirements. Flocculants are needed to make the water quality b. Many waterworks use inorganic flocculants, but the amount of inorganic flocculants is large, resulting in poor effect of sludge increase. Anionic polyacrylamide acrylamide monomer was 0.012%. The molecular weight of anionic PAM was 12.5 million and the content of acrylamide monomer was 0.013%. The concentration of two kinds of PAM is 0.05%. They are used after refrigeration for 24 hours.
(1) PAM pretreatment sludge takes lOml sludge and puts it into a 300 ml beaker. Six-unit mixers are used to mix at 1130 RPM speed for 30 seconds, and then the PAM is added to the sludge quickly and quantitatively. The PAM is stirred at lOOrpm speed for 30 seconds, then the speed of the mixer is reduced to 20-30 rpm and the slow stirring speed is 60 seconds to promote flocculation. The specific resistance of pretreated sludge, capillary water absorption time (CST), the viscosity of filtrate and the viscosity of centrifuge were measured.
(2) The specific resistance is tested by Brinell funnel according to the test b proposed by Coackley. The diameter of Brinell funnel is 80 mm. The filter paper is made of 70 mm medium speed filter paper. The vacuum degree of the test is controlled to 0.01 MPa. The experiment was repeated three times to get the average value.
(3) In order to reduce specific resistance and improve sludge dewatering effect, sludge should be pretreated before sludge dewatering. Sludge pretreatment bs include freeze-thaw pretreatment, heat treatment, acid treatment, alkali treatment, lime pretreatment and polymer flocculant pretreatment. Polymer flocculant polyacrylamide (PAM) pretreatment is the most widely used pretreatment b at home and abroad.
(5)實(shí)驗(yàn)研討標(biāo)明：投加陽(yáng)離子型和陰離子型PAM后污泥比阻都降低近2個(gè)數(shù)量級(jí)，顯著改善了污泥的脫水性能。陰離子
(6)依據(jù)CST值變化肯定PAM最投加率與測(cè)定比阻得到的最投加率分歧。并且CST值與比阻之間存在線性相關(guān)關(guān)系，比阻值越大，CST值越大，因而能夠采用CST值來(lái)近似替代污泥比阻反映污泥的脫水性能。與比阻相比，cST值測(cè)定快速、煩瑣，不但適用于實(shí)驗(yàn)室研討，還可用于消費(fèi)現(xiàn)場(chǎng)，快速理解污泥脫水性能的變化，使操作人員及時(shí)調(diào)楚PAM投加率，儉省藥劑費(fèi)。is used as flocculant, and the dosage is inorganic flocculant. One fiftieth of the flocculants, but the effect is several times to dozens of times that of inorganic flocculants. Especially the polyacrylamide produced by our company, the residual monomers have reached the food grade (less than 0.05%), close to the advanced level abroad, non-toxic, more suitable for the treatment of drinking water, and better for the use of organic pollutants polluted river water and anionic polyacrylamide.
Polyacrylamide is used to recover lost starch and distiller's grains in starch and alcohol factories. At present, the starch in the waste water discharged by many starch factories is very high. After discharging, it affects the environment, wastes resources, and adds PAM to make starch precipitate. The precipitate is filtered by pressure filter to become cake and can be used as feed. A large number of distillers'grains in the alcohol factories are processed by this process. A certain alcohol factory in Heilongjiang Province uses polyacrylamide as flocculant, which recycles the distillers' grains and obtains a great deal of experience. Economic benefits.
Polyacrylamide is used as water shutoff agent for profile control and water shutoff in Oilfield and oil displacement agent for tertiary oil recovery.
Polyacrylamide is used as paper-making additive. PAM is widely used in paper-making. It can be used as long fiber paper-making dispersant, wet and dry reinforcing agent, retention aid, filter aid and flocculant of paper-making wastewater.
The latest type of water treatment agent polyacrylamide, when treating sewage and water in many occasions, the combination of anionic polyacrylamide and cationic polyacrylamide has a very significant and synergistic effect than using one kind of ionic polyacrylamide alone. The ability of PAM to reduce surface tension is much greater than the ability of cations or anions existing alone under the same conditions. For the requirement of low surface tension, both anionic and cationic polyacrylamide need to be used at the same time. If they are used improperly, white precipitates will be produced and the effect of using them will be lost. PAM has the characteristics of amphoteric ions. It can complete the coordination of anions and cations. There is no precipitate on the surface. Especially, it is more convenient to use PAM as a flocculant because of the complex water quality or the changeable nature of water.
The sludge used in sewage pretreatment is taken from the sedimentation tank with Qiantang River water as its source of water, and PAC is used as a flocculant in the water plant. The sludge was naturally concentrated to a solid content of 2.7%-2.8%. The organic matter content in the sludge was 12.1%, SJ content was 52.1%, Al content was determined. The content was 20.2%. There are three types of PAM: cationic, anionic and nonionic. Non-ionic PAM dissolves slowly and is generally not used for sludge pretreatment. Therefore, only two representative cationic polyacrylamides and anionic polyacrylamides are selected in the experiment. The molecular weight of cationic PAM was 12 million and the content of
