摘要:
为了满足太湖地区农村污水处理占地面积小、除磷脱氮效率高、管理简单、运行和建设费用低的要求,研发了水解/脉冲滴滤池/人工湿地组合新工艺,并进行了工程规模的试验研究.结果表明:脉冲滴滤池最佳水力负荷为7.0 m3/(m2·d),布水周期为20 min,回流比为2.0.脉冲滴滤池在此运行条件下,与水力停留时间为12 h的前置水解池,以及水力负荷50 cm/d的后置人工湿地组合运行时,该组合工艺对COD,TN和TP的平均去除率分别达91%,95%和95%.
Abstract:
In order to meet the technical requirements of smaller occupancy area, higher efficiency of nitrogen and phosphorus removal, easier maintenance and lower operation and construction cost in the treatment of rural sewage in the Lake Taihu valley, a full-scale experiment on use of the combined process of hydrolysis/pulse trickling filter/constructed wetland was carried out. Results show that for pulse trickling filter the optimal hydraulic loading rate, sprinkling period and reflux ratio are 7.0 m3/(m2·d), 20 min and 2.0 respectively. With these optimal operation parameters the average removal efficiencies of COD, TN and TP can be 91%, 95% and 95% respectively when the prepositive hydrolysis tank operating at hydraulic retention time of 12 h, and postpositive constructed wetland operating at hydraulic loading rate of 50 cm/d.
