摘    要:对传统型的地下渗滤系统进行了改进,建立了一套新型的地下渗滤试验装置.采用两种不同的进出水方式对此渗滤系统的启动周期进行了比较试验,结果表明:在进水CODCr为250~400 mg/L、氨氮为70~lOO mg/L时,初期采用间歇进水的方式可使启动周期缩短为18 d;稳定运行时HRT为6 h,COD去除率可达79%以上.此研究为新型地渗系统的设计提供了思路.

关 键 词:分散污水  土地处理  地下渗滤系统  启动周期  改进

Abstract:A new improved subsurface infiltration setting was built by renovating the traditional one.The experiment was conducted to investigate the startup time under the two types of inflow wastewater,continuous and non-continuous.The result indicated that the new system startup time was reduced to 18d in the mode of interim inflow under the condition of COD of sewage range between 250 and 400 mg/L,and NH4 -N between 70 and 100 mg/L.COD removal efficiency can reach 79% while the hydraulic residence time(HRT) maintains more than 6h.The result may provide a solution for designing a renovating subsurface infiltration system.
Keywords:decentralized wastewater  land treatment  subsurface infiltration system  startup time  renovation
