摘　　要：某公司2个矿井污水处理站均采用三级处理工艺处理矿井污水。本文通过将2个矿井污水处理站连续监测14 d的出水浊度值进行对比,得出以下结论:A矿矿井污水处理站二级处理工艺出水浊度值在0.40~3.00 NTU之间,三级处理工艺出水浊度值较平稳地维持在0.05~0.10 NTU之间,其三级处理工艺出水浊度去除率均达到90%以上;B矿矿井污水处理站的二级、三级处理工艺出水浊度值在1.00~2.00 NTU左右,二三级处理工艺出水浊度值变化差值较小,故三级处理出水浊度去除率较低,最低至4.59%。The two mine sewage treatment stations of a company all use the three-stage treatment process to treat mine sewage.In this paper,by comparing the effluent turbidity values of two mine sewage treatment stations monitored continuously for 14 days,the following conclusions are drawn:the mine sewage treatment station of Mine A is the turbidity value of the effluent of the secondary treatment process is between 0.40~3.00 NTU,and the turbidity value of the effluent of the tertiary treatment process is relatively stable between 0.05~0.10 NTU,and the turbidity removal rate of the effluent of the tertiary treatment process is above 90%;the turbidity value of the effluent from the secondary and tertiary treatment processes of the mine sewage treatment station in Mine B is about 1.00~2.00 NTU,and the difference between the turbidity values of the effluent from the secondary and tertiary treatment processes is small,so the turbidity removal rate of the effluent from the tertiary treatment is relatively small,minimum 4.59%.
