摘要
选取某高校干道生活污水为研究对象,采用阶梯式生态滤盘处理系统,将经预处理的生活污水引入该系统进行跌落曝气好氧处理,并对出水主要水质指标进行测定。结果显示,阶梯式生态滤盘处理系统对COD、BOD5、SS、TP、NH_3-N的去除率分别为83.67%、83.25%、91.38%、91.07%和77.73%,出水水质能达到GB 18918—2002的一级B标准,处理效果较好,具有良好的推广前景和应用价值。
The multistep ecological filter-disc system was used to treat the domestic sewage from a university. The pretreated domestic sewage was introduced to the system to perform drop aeration aerobic treatment, and the main effluent quality indexes were determined. The results showed that the removal rates of COD, BODs, SS, TP and NH3 -N were 83.67% , 83.25% , 91.38% , 91.07% and 77.73% respectively. The effluent quality could meet the first class B criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant （GB 18918 -2002）. The treatment system has good application prospect and value due to its high treatment effect.
