生活污水中污染物在改进SBR法不同工序中转化规律的实验研究

Study on Changing Law of Domestic Wastewater Pollutant in Different Process of Improved SBR

探讨了生活污水中污染物在改进SBR法不同工序的转化规律。试验结果表明:反应周期宜控制在8h,其中两次厌氧和一次好氧各1h,二次好氧3h,沉淀、排水及闲置共2h。经处理后出水COD、NH3 -N及NO3 -N、TP的浓度分别为35-90mg·L-1、0-9. 5mg·L-1、1. 8-9. 0mg·L-1、0. 4-1. 1mg·L-1,优于传统的SBR法,达到了国家污水综合排放一级标准。

The changing law of domestic wastewater pollutant in different process of improved SBR was studied. The results showed that reaction period may be controlled in 8 hours, the two anaerobic times and the first aerobic time was 1 hours respectively in it, the second aerobic time was 3 hours; precipitation time , drainage time and idle time were 2 hours altogether, concentration of COD.NH3 - N.NO3 - N .TP in the effluent was 35 -90 mg/L.0 - 9.5 mg/ L.1.8 -9.0 mg/ L.0.4 - 1.1 mg/L respectively, the improved SBR is superior to the traditional SBR. It can meet the Wastewater Synthetical Discharge First Standard of China.
