【摘要】 针对传统污水快速渗滤土地处理系统水力负荷低 ,占地面积大的弱点 ,提出了采用人工砂和天然砂作为渗滤介质建立复合系统的试验方案 ,并以洗浴污水为研究对象进行了 5个月的室内试验研究。结果表明 ,复合系统具有较高的水力负荷和较好的去污效果 ,其对COD、BOD5、SS和阴离子洗涤剂 (以MBAS代表 )的平均去除率分别为 86 2 5 %、86 75 %、98 95 %和 90 86% ;处理出水中COD、BOD5、SS和阴离子洗涤剂的平均浓度分别为 17 3 0、5 84、0 3和 0 18mg l更多还原

【Abstract】 In the light of the low Hydraulic Loading of traditional wastewater rapid infiltration land treatment system,a experiment project of constructing composite system by using artificial and natural sands is put forward.A lad\|scale experiment has been conducted with bath wastewater for five months.The results show that the composite system has higher Hydraulic Loading and better removal effect for bath wastewater.The average removal rates for COD,BOD\-5,SS and MBAS are 86.25%,86.75%,98.95% and 90.86% respectively;the average concentrations of COD,BOD\-5,SS and MBAS in the treated effluent are 17.80,5.84,0.3 and 0.18 mg/l respectively.更多还原
