摘要
通过试验室模拟生活污水的运行,对一体化生活污水净化反应装置的生物降解能力进行了研究。该装置日处理生活污水300L,总水力停留时间(HRT)为3.8d。试验结果显示,COD和BOD的平均去除率分别为83.48%和95.92%,出水达到《城镇污水处理厂污染物排放标准》(GB18918—2002)一级B标准,且抗冲击能力强。由于二次沉淀区运行不当,NH3-N、TN和TP去除效果不理想,但试验证明装置本身具有脱氮除磷功能。
An experimental study on simulating the operation ofintegrated purifying reactor for domestic sewage treatment has been conducted for investigating the biodegradation performance. The results indicated that the average percentage removal for COD and BOD was 83.48% and 95.92% respectively, the water quality of effluent water reached the ＂Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant＂ level 1B and the reactor had a strong ability of minimizing the negative affects associated with influent spikes at a fixed hydraulic retention time （HRT） of 3.8 d and the flow rate of 300 L·d-1.This test proved that the reactor could remove nitrogen and phosphor, but it was also noted the removal of NH3-N, TN and TP was not desired in reality because of the secondary clarifier operating problems.
