Abstract:

The wastewater treatment process of a tannery is converted int o dyeing wastewater treatment process, and debugged. A new type of liquid PAC, which is produced in a plant in Xiaoshan,is used for debugging. The treatment efficiency is better than that of ferrous sulfate, the average removal rate of COD_Cr is up to 61.78%. It also indicates that such a simple coagulation - aer obic treatment can ensure the dyeing wastewater to meet the requirement of the discharge standard. So, this reformation is feasible.

Key words: dyeing wastewater, tennery wastewater, coagulation

摘要：

对某皮革厂废水处理工艺改造用来处理印染废水,并对其进行调试。调试选用了萧山某厂生产的新型液体聚合氯化铝,处理效果好于硫酸亚铁,平均COD_Cr去除率达到了61.78%。同时经调试表明这样一个简单的混凝—好氧处理工艺基本上能保证此类印染废水排放达标。
