摘　　要：传统生物脱氮工艺对低C/N生活污水处理效果差,因此对水解-好氧工艺处理低C/N城市污水进行了试验研究。通过测定不同硝化液回流比、污泥回流比、进水水力负荷时水解池对污染物的去除效果,得到工艺最佳工况运行参数为:硝化液回流比150%,污泥回流比200%,进水水力负荷0.34 m3/(m2·h)。在最佳工况下,水解-好氧工艺对CODCr、TN的去除率高达82.9%和64.5%。该结论可供低C/N污水处理工程参考借鉴。Because of the poor effects of traditional biological nitrogen removal process for treating low C/N domestic waste-water, the experimental study of treating low C/N municipal sewage by hydrolysis aerobic process was carried out. Through the determination of the recycle ratio of different nitrification liquid, the sludge recycle ratio, the removal effects of the hydrolysis tank on pollutant, the process optimum operation parameters were obtained as follow： nitrification liquid recycle ratio 150 %, sludge recycle ratio 200 %, water inlet surface load 0.34 m^3/（m^2 ·h）. In the optimum condition, the removal rate of hydrolysis aerobic process on CODc~,TN have up to 82.9 % and 64.5 %. The conclusion can be used for reference in low C/N sewage treatment project.
