皮革厂制革废水处理主要是生物处理，用成熟的工艺来处理这些污水，首先我们要有相应的处理，在这个处理过程中主要的目的就是去除尽可能多的油类、硫化物等物质，其次还降低了有机物和有毒物质的浓度，以确保后续生物处理的高效稳定运行。
***后要根据实验结果再进行实际的操作。聚丙烯酰胺pam作为絮凝剂的使用，使用十分普遍。

the amount of sewage in the city is very large. it not only includes the sewage produced in industrial production, the sewage produced by employees, but also the daily sewage of urban residents, as well as the sewage and wastewater generated by natural phenomena such as rain and snow. but is the use of a variety of equipment and technology of city sewage treatment technology, the use of polyacrylamide as flocculant sewage sewage containing material removed from the water, which makes the material change harmful for useful substances, and water is also obtained in this process of purification, such resources will be fully utilized, the process of urban sewage treatment there are two levels of pretreatment, treatment and sludge treatment.
in the process of city sewage treatment, mainly including the following process: concentration, digestion, composting or domestic landfill, mainly through concentrated mechanical thickening or gravity concentration, general mechanical concentration is more extensive, and the digestion is mainly anaerobic technology, more than the most important in the process of sludge dewatering in city sewage. treatment need to add water treatment flocculant, polyacrylamide and pam is the most suitable flocculant. but there are many kinds of polyacrylamide. the following is an introduction to how to determine the model before use:
mud mud sample of 1. water machine and analysis of sludge solid content index
the 2. 1g flocculant dry powder is evenly dissolved in the water of 100ml, so that 1/1000 of the solution is added.
the concentration of 3. mud sample adding volume of 1/1000 flocculant, the flocculation was observed in this process, the size of 30 flocculation and stir, then add the solution of 250ml cylinder, set aside for ten minutes, observe the filtrate volume. and record it.
4. content: dispersity, dissolution time, dosage of medicament, flocculation effect, flocculation size and so on
finally, the actual operation should be carried out according to the results of the experiment. the use of polyacrylamide pam as a floccul
混凝的沉淀和气浮是皮革厂废水常用的预处理方法，混凝沉淀主要就是通过投加药机，是水中的硫化物和铬粒子进行沉淀而去除：对于气浮来说，主要就是通过投加絮凝剂（大多数都是聚丙烯酰胺），通过了微小气泡的上浮和粘附作用，去除了水中的油类等的物质。为什么大多数用聚丙烯酰胺？是因为聚丙烯酰胺被作为絮凝剂来用的话效果很明显。
许多使用过或者有水处理方面经验的朋友都知道，聚丙烯酰胺是有机絮凝剂，聚合氯化铝是无机混凝剂。可是这两种絮凝剂真的可以同时使用吗？效果会怎么样？相信许多人都会有这个疑问，今各种新老客户朋友解答。
在处理污水的时候，有些污水单一使用一种絮凝剂是很难达到客户要求的效果。但是如果聚丙烯酰胺和聚合氯化铝能够同时使用的话，能够非常简单觉得污水问题。说到这，有些客户朋友就想着急去实验看看，不要着急，这里面还有一点小学问，那就是投放的次序，和间隔时间。聚合氯化铝pac是属于混凝剂，与污水反映的时间非常短，加入后需要充分强烈的混合，而聚丙烯酰胺pam属于絮凝剂，混合时不能太过剧烈以免破坏已经形成的絮体，所以正常情况下应该是先加入聚合氯化铝pac再加入聚丙烯酰胺pam，但是为了保险起见，还是建议大家通过做小样的试验来决定***终的加药顺序。加药间隔的时间，加药的比例，加药的量及其混合的强度都需要一个严谨科学的实验，切忌把两种药剂直接放在一起使用，否则会直接影响污水处理效果，从而增加成本。
在皮革废水处理时，聚丙烯酰胺凝聚过程都有哪些阶段？
1.向废水中添加聚丙烯酰胺
2.絮凝剂在液体中进行扩散
3.为了使絮凝剂和悬浮物的粒子接触而进行搅拌
