再生水处理工艺选取

Reclaimed water treatment process selection

为实现生产工艺的高效稳定运行和低廉的维护运行管理成本,并保证出水水质达到行业标准要求,对国内3种成熟的再生水处理工艺进行比选.结果表明,银川市某污水处理厂再生水工程选取混凝、沉淀、过滤工艺,即传统老三段工艺最优.该方案在长期稳定运行及维护管理等方面优势明显.

To achieve efficient and stable operation of the production process,low maintenance operation and management costs and to ensure water quality satisfying industry standards,three mature water treatment processes were compared. Result shows that traditional process(coagulation,sedimentation,filtration process) is optimal process for some sewage treatment plants in Yinchuan city,it is obvious advantages on the hand of running stability and maintenancing management in the long terms.
