原料皮的不同、加工工艺不同、成品不同等等这些因素都会使得污水水质之间有很大的差异，对于制革厂来说，污水不仅量很大，而且污水的成分复杂、高浓度的有机废水、其中含有大量的石灰、染料、盐类、油脂以及其他有毒有害物质，那么对于皮革厂产出的废水应该怎么处理呢？

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high strength.General light porous or insulating materials such as boiling rocks, diatomite, perlite, sea pumice, expanded vermiculite is the difference in hardness, strength is poor, with its system of thermal insulation products or light refractory products, intensity difference flaws.The advantages of their shortcomings is drift beads, so drift beads have more competitive advantages, used more widely.
4, excellent electrical insulation, non-conductive: choose after degaussing beads drift beads, is the performance of insulation materials, conductive.Insulation resistance are commonly by the rise of temperature, drift beads, on the other hand, increases with the increase of temperature resistance.This advantage is don't have other insulating materials.So, it can make is performance under the condition of high temperature 
、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。

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
