摘要
针对北方农村三格化粪池出水,中试采用陶粒作填充物的曝气生物滤池,研究在不同气水比的条件下陶粒曝气生物滤池反应器处理三格化粪池出水的情况。装置的挂膜方式选用接种挂膜法,在保持陶粒曝气生物滤池反应器滤速为0.01 m^(3)·h^(-1)的工况条件下,研究了气水体积比分别为1∶1、2∶1、3∶1和4∶1时反应器去除三格化粪池出水中COD、NH_(3)-N和TP的效果。结果表明:当气水体积比为2:1时,陶粒曝气生物滤池对COD、NH_(3)-N和TP的平均去除率分别达到81.8%、79.1%和29.4%。
Based on the effluent from the three-cell septic tank in the rural areas of northern China,the pilot test was conducted to study the treatment of the effluent from the three-cell septic tank by the bioreactor of the ceramic aerated biofilter as the filling material.The membrane hanging method of the device was selected.Under the condition of maintaining the filtration rate of the ceramic aerated biological filter reactor at 0.01m^(3)·h^(-1),the removal efficiency of COD,NH_(3)-N and TP from effluent of three-cell septic tank was studied when the volume ratio of gas to water was 1∶1,2∶1,3∶1 and 4∶1 respectively.The results showed that when the gas-water volume ratio was 2:1,the average removal rates of COD,NH_(3)-N and TP in the ceramic aerated biofilter reached 81.8%,79.1%and 29.4%,respectively.
