摘要
为确定沈抚灌渠下游生态修复技术方案,响应生态修复的总体目标,首先对现场场地条件进行调查,现场采样分析,并进行湿地构筑物模拟试验研究,考查了湿地构形、基质与水力停留时间对COD,NH4+-N,TP去除效果的影响。模拟实验表明:表面流和垂直流构筑湿地污水处理技术可以有效的去除污水中的COD,NH4+-N,TP,采用构筑湿地作为核心技术修复沈抚灌渠污水是可行的。
For determining the ecological restoration solutions of Shen-fu irrigation channel,and in answer to the overall objective of ecological restoration,first,the research investigated the field conditions,then did the on-site sample analysis and constructed wetland simulation studies at last.The studies tested how the structure,base materials and hydraulic detention time to affect the treatment efficiency of COD,NH4＋-N and TP.The experiment result indicates that the surface flow and vertical flow wetland treatment technology can effectively remove the COD,NH4＋-N and TP in sewage,and it is feasible to use wetland technology to restore the Shen-fu irrigation channel＇s sewage as a core technology.
