詳細說明
 嘉興制革廢水陽離子聚丙烯酰胺

 

    嘉興革廢水主要來源于鞣前準備,鞣制和其他濕加工工段。污染最重的是脫脂廢水、浸灰脫毛廢水、鉻鞣廢水,這3種污水約占總廢水量的50%,但卻包含了絕大部分的污染物,各種污染物占其總量的質量分數為:CODcr80%,BOD575%,SS70%,硫化物93%,氯化鈉50%,鉻化合物95%。
皮革廠廢水特點有以下幾個:
①水質水量波動大;

②可生化性好;

③懸浮物濃度高,易腐敗,產生污染量大;

④廢水含S2-和鉻等有毒化合物。

    污水中污染物組成復雜,綜合污水的處理方法也很多,有生化工藝和物化等方法。國內皮革工業通常采用物化處理和生化處理相結合的方法,此法投資省,運行費用低,能夠穩定達標排放。
