摘要
本论文主要研究了Eckenfelder生物滤池模式在土壤地下渗滤化沟工艺设计中的设计参数及其不同条件下的范围值。实验结果明,土壤的影响因素可以用土壤特性常数n表示且n值越大,有污染物BOD_5去除率越高;当BOD_5去除率达85%时,n值约为0.60;且工艺设计时应根据不同污染物去除率的要求,选择适当的沟深水力负荷,沟深一般在0.30-0.80m范围,水力负荷宜取040-0.100m~3/m.d。
     论文同时利用贵州省环境科学研究设计院5号宿舍楼(2m~3/d)活污水处理工程运行结果对上述研究结果进行了验证,结果表明kenfelder生物滤池模式运用于土壤地下渗滤净化沟工艺设计是行的,设计参数与实际运行结果吻合较好。
The application of the modle of Eckenfelder-biofilter in the soil surface infiltration trench systems were studied by auther . According the experimental results, the bigger the characteristic factor "n", the her the removed rate of organic wastes in wastewater. At the condition the removed rate 85%, "n" was about 0.60. According to the conditions various wastewater and soils, the typical date of the deeps of the ichs were 0.30~0.80m, and the hydraulic load were 40~0.100m3/m.d.
