摘要
详细研究了屠宰废水的水质特性,确定了以加压生化+化学混凝为主导工艺的屠宰废水处理方法。实验证明在最佳条件下处理屠宰废水,COD_(cr)去除率在92％以上、BOD_5去除率在90％以上、出水pH在7～9之间、SS(固体悬浮物)去除率在98％以上、NH_3-N去除率在45％以上、油脂去除率100％,且运行稳定,各项指标均可达到肉类加工工业水污染物排放一级标准。
The characteristic of slaughter wastewater is studied in this paper. It settles the treatment mainly by bio -chemical method under raised pressure combined with Chemical coagulation process. The experiment proves under optimum conditions, the removal efficiency of CODer is more than 92%, the removal efficiency of BODs is more than 90%, the pH of effluent is between 7 and 9, the removal efficiency of SS, NH3 -N and oil are 98% 45% and 100% respectively. The running process is stable and the properties of effluent reach the first grade discharge standard of meat working industry wastewater.
