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,提出了采用渗透性能良好的天然砂作为主要渗滤介质建立人工快速渗滤系统的试验方案,并以受污染河水为研究对象进行了为期一年的现场试验研究.结果表明,在1.5m/d的水力负荷条件下,人工快速渗滤系统对污染河水具有较好的污染物去除效果,其对SS、CODcr、BOD5、NH3 N、T P和LAS的平均去除率分别为89.51%、77.82%、85.33%、98.28%、60.19%和94.25%;处理出水中SS、CODcr、BOD5、NH3 N和LAS的平均浓度分别为2.5mg/L、15.7mg/L、2.89mg/L、0.32mg/L、0.86mg/L和0.05mg/L.
In the light of the low Hydraulic Loading of traditional wastewater rapid infiltration land treatment system, a experiment project of building Constructed Rapid Infiltration (CRI) system by using natural sands is put forward. A on-site experiment has been conducted with polluted river water for one year. The results show that the CRI system has better removal effect for polluted river water in a Hydraulic Loading (HL) of 1.5 m/d. The average removal rates for SS, COD_(cr), BOD_5, NH_3-N, T-P and LAS are 89.51%, 77.82%, 85.33%, 98.28%, 60.19% and 94.25% respectively; the average concentrations of SS, COD_(cr), BOD_5, NH_3-N and LAS in the treated effluent are 2.5 , 15.7 , 2.89 , 0.32 , 0.86 and 0.05 mg/L respectively.
