新型微动力生活污水处理装置的性能研究

Study on the performance of micro-power domestic sewage treatment device

为了有效改善日益污染严重的农村水环境,解决现有生活污水处理装置出水效果差、运行不稳定、能耗高和自动化控制程度低等问题,进行了微动力生活污水处理装置的性能研究。研究结果表明,该装置对生活污水处理效果良好,在装置连续运行的70 d内,出水CODcr、氨氮、总氮、总磷的最高质量浓度分别为56.72、4.92、19.14和0.98 mg·L^-1,浊度小于9 NTU,出水水质指标符合《城镇污水处理厂污染物排放标准》(GB18918-2002)中一级B的排放标准。

In order to improve the increasing polluted domestic water environment effectively,and solve the problems of poor effluent effect,unstable operation,high energy consumption and low degree of automation control of the existing domestic sewage treatment device,the performance of micro-power domestic sewage treatment device was investigated.Experimental results indicated that the treatment of the divice was good.Within 70 days of continuous operation of micro-power domestic sewage treatment device,the average concentration of CODcr,NH3-N,TN and TP were 56.72,4.92,19.14,0.98 mg·L^-1 respectively and the turbidity was less than 9 NTU.The effluent could come up to the first B level standard of“Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant”(GB18918-2002).
