摘要
通过室内实验并结合实际工程研究了一种新型组合式人工快渗系统处理氨氮负荷较高的污水。结果表明,简易曝气装置有效降低了人工快渗池的污染物负荷,保障了整个系统的出水水质。实际工程中,经过简易曝气池的预处理,人工快渗池的水力负荷可达2.5 m/d,降低了人工快渗系统的占地面积,出水COD、氨氮、总氮等指标达到了《城镇污水处理厂污染物排放标准》(GB/T18918-2002)一级A排放标准。
The technical and economical feasibility of using a simple aeration tank as a pretreatment process in the constructed rapid infiltration system was investigated through indoor experiment and practical engineering when the ammonia nitrogen load of influent was high.The results showed that simple aeration tank reduced contamination loads effectively,ensuring the effluent quality.Under the pretreatment of the simple aeration tank,the hydraulic load of constructed rapid infiltration system increasd greatly to as much as 2.5 m/d in practical engineering,which greatly decreased the area of the constructed rapid infiltration system.The COD,NH_3-N,TN of the effluent were good enough to meet the requirements of class I(A)of the national wastewater discharge standard of urban sewage treatment plants(GB/T 18918-2002).
