雖然PAC聚合氯化鋁它有這么多的優(yōu)點(diǎn)，但是在實(shí)際使用過(guò)程中，還是有多地方需要注意的，下面，就讓宜家小編為大家說(shuō)說(shuō)PAC聚合氯化鋁使用時(shí)的注意事項(xiàng)。
安徽聚合氯化鋁在我們的生活中非常的常見(jiàn)，是一種比較高效無(wú)機(jī)高分子的絮凝劑，在對(duì)于水處理凈化方面非常的重要，但是針對(duì)于我們現(xiàn)在市場(chǎng)上面這么多的聚合氯化鋁，對(duì)于質(zhì)量的選擇也是非常的重要的，接下來(lái)，安徽聚合氯化鋁常見(jiàn)總結(jié)了五個(gè)方面教你怎么樣去判斷聚合氯化鋁的質(zhì)量好壞。
1、聚合氯化鋁PAC的顏色和質(zhì)量有關(guān)系。聚合氯化鋁一般情況下，從外觀上就能夠看出來(lái)，分褐色，土黃色，黃色，淡黃色和白色。褐色的聚合氯化鋁屬于低檔，土黃色聚合氯化鋁屬于中檔產(chǎn)品，黃色和白色的都屬于高檔次的產(chǎn)品。價(jià)格依次增長(zhǎng)。
2、聚合氯化鋁中起主要作用的成分是三氧化二鋁，判斷產(chǎn)品質(zhì)量好壞要看三氧化二鋁的含量，生活級(jí)水處理三氧化二鋁質(zhì)量分?jǐn)?shù)要達(dá)30%以上，工業(yè)級(jí)水處理三氧化二鋁質(zhì)量分?jǐn)?shù)要達(dá)27-29%。
五個(gè)方面告訴你怎么樣去判斷聚合氯化鋁的質(zhì)量好壞
3、聚合氯化鋁的鹽基度，一般引起聚合氯化鋁形態(tài)多變的基本成分是OH根離子，衡量聚合氯化鋁中OH離子的指標(biāo)叫鹽基度，通常把鹽基度還定義成聚合氯化鋁分子中OH與Al量的百分比，一般鹽基度要在40-90%以內(nèi)。
4、聚合氯化鋁的溶解度就是指聚合氯化鋁放入清水后有百分之幾可以融化掉。飲用水處理用的聚合氯化鋁的溶解度是99.7%，也就是說(shuō)0.3%的水不溶物。工業(yè)廢水處理用聚合氯化鋁的溶解度是98%，也就是有2%的不溶物。也就是說(shuō)，如果產(chǎn)生超過(guò)比例的不溶物，就說(shuō)明此聚合氯化鋁的質(zhì)量不符合。
5、聚合氯化鋁溶解后，有不溶物沉積在泵箱底部，時(shí)間久了，越來(lái)越多，現(xiàn)在都是人工清理，費(fèi)時(shí)費(fèi)力，所以可以從水不溶物的含量來(lái)判斷該P(yáng)AC產(chǎn)品的質(zhì)量。
通過(guò)上述的文章是不是知道了我們要怎么去判斷聚合氯化鋁質(zhì)量的好壞呢？只有我們選擇到比較質(zhì)量比較高的聚合氯化鋁，在使用的時(shí)候才不會(huì)出現(xiàn)問(wèn)題，安家凈環(huán)保是一家專業(yè)從事聚合氯化鋁生產(chǎn)銷售的廠家，歡迎前來(lái)咨詢合作

The amount of polyacrylamide used by polyacrylamide manufacturers to treat a ton of wastewater is usually 7-10 grams, usually 2-4 gram象的根本原因是聚合氯化鋁在水處理領(lǐng)域具有獨(dú)特的優(yōu)勢(shì)。
首先，目前鋁鹽的凈水效果比鐵鹽好，但鋁鹽的缺點(diǎn)之一是低溫絮凝效果很差。但聚合氯化鋁在處理低溫水方面仍有較好的效果。聚合氯化鋁的絮凝效果受常溫或低溫水的影響較小。除此之外，現(xiàn)有的凈水產(chǎn)品大多需要在低濁度和低污染水的處理中加入大量助劑，以便在后續(xù)的處理中取得更好的效果，但不需要聚合氯化鋁。
聚合氯化鋁的主要特點(diǎn)是處理低濁度、低污染的廢水。
聚合氯化鋁PAC處理后的水鋁含量很低，這也是目前PAC在飲用水處理中最常用的主要因素之一。此外，優(yōu)質(zhì)飲用水級(jí)PAC使處理后的水更加安全。聚合氯mide with good quality is less, and the amount of polyacrylamide with minor addition is slightly

1、 根據(jù)原水不同情況，使用前可先做小試求
2、加藥按小試求得。
moval 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.

1、操作不當(dāng)，有的是不專業(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。

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.

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)。
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。?

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.
