摘要
在无砾石微孔管中试系统中,设置了土壤、植物、管径三个参变量进行正交实验,对系统中各个单体产生的不同处理效果进行分析,并研究了降雨量、温度、进水水质对污染物去除率的影响。结果表明:大管径和砂壤土处理效果较好,系统中氮的去除率随进水浓度和气温变化较大。
In the medium-scale gravel-less perforated pipe leach fields,the three parameter of soil,plant,and diameter were set up for the orthogonal experiment.Different treatment effects in each unit in the system were analyzed.The impact of quantity of rainfall,temperature,and influent water quality to the pollutant removal rate were studied.The results showed that the big diameter and sandy loam treatment effect was better.With the change of influent water quality and temperature,the removal rate of nitrogen varied greatly.
