微电解-A/O生化组合工艺处理实验室高浓度废水

Micro-electrolysis-A/O Biochemical Combination Process for the Treatment of High-concentration Laboratory Wastewater

高校实验室废水具有排放周期和排放量不定、浓度和成分复杂多变等特性。为减少实验室高浓度废水排放对周边环境造成的污染,采用微电解-A/O生化组合工艺对某高校环境学院实验室废水进行处理。工程实践表明,该工艺运行稳定,抗冲击负荷能力强,处理成本低,处理效果好,CODcr、SS和NH3-N的总去除率分别达到87.2%、90.5%和79.9%。出水水质达到《污水排入城镇下水道水质标准》(GB/T 31962-2015)和污水处理厂纳管要求。

Laboratory wastewater in colleges and universities has the characteristics of indefinite discharge cycle and quantity,complex concentration and composition.In order to reduce the pollution to the surrounding environment caused by the discharge of high concentration laboratory wastewater,a micro electrolysis-A/O biochemical combination process was used to treat the laboratory wastewater of the Environmental College of a university.The engineering practice shows that the process has stable operation,strong shock load resistance,low treatment cost and good treatment effect.The total removal rates of CODcr,SS and NH3-N are 87.2%,90.5%and 79.9%respectively.The water quality of the effluent meets the requirements of"Wastewater Quality Standards for Discharge to Municipal Sewers"(GB/T 31962-2015)and the requirements of the sewage treatment plant for collecting wastewater through pipes.
