复合快渗系统处理生活污水的模拟试验研究

SIMULATED EXPERIMENT STUDY ON SEWAGE BY COMPOSITE RAPID INFILTRATION OF DOMESTIC SEWAGE TREATMENT SYSTEM

用自制的实验室快速渗滤系统模拟反应器对生活污水进行处理.研究结果表明,此套实验室模拟快渗处理生活污水系统对CODCr、TN、TP去除效果良好,对CODCr的去除率最大值为95.4%,TN为74.7%,TP为83.5%.在布水4 d后,出水CODCr,TN和TP质量浓度分别稳定在20 mg/L,20 mg/L和1.5 mg/L以下.

This paper describes a simulated study on the sewage treatment for school water stations. A constructed rapid infiltration system was made in this laboratory. The results show that this set of laboratory simulation of rapid infiltration on the treatment of domestic sewage system CODcr, TN, TP good removal efficiency, the removal of the maximum CODcr for 95.4%, TN for 74.7%, TP for 83.5 %. In continuous water four days later, the effluent CODcr, TN and TP are steady at 20 mg/L and 20 mg/L and 1.5 mg/L following.
