摘要
结合姜堰市城市生活污水处理厂运行,对CASS工艺中水力停留时间对COD、TN和NH3-N去除率的影响进行了探讨。通过运行工况和进水水质的改变试验,以积累大量的试验运行数据和实际处理效果,探讨水力停留时间对去除率的影响,确定适宜的水力停留时间。实验研究表明,水力停留时间控制在18h比较适宜,这样既经济又可以获得较稳定的处理效果。
Based on operation of urban sewage treatment plant of Jiang Yan city,the impacts of hydraulic staying time of CASS techniques on removal rate of COD,TN and NH3-N are discussed.The result shows that optimum duration of hydraulic staying time is 18 hours,the disposal effects are both economic and stable.
