The Study On The Application Of Multiple Manual Marsh In The Treatment Of Agriculture Surface Resource Pollution

Based on the analysis of pollution actuality for Fuxian Lake, the paper discusses the application of constructed wet land on agriculture and the non-point source pollution treatment of county and it strives to explore a new approach for lake-agriculture and the non-point source pollution treatment of county in China. The new ideas and methods are brought forwardthrough the lakes environment protection for non-point source pollution mainly. The paper presents the compared study for the technology scheme, plant varieties, undercurrent-bed stuffing, non-point pollution HRT and concentration of inflom and outfall on stages and combines the structure of Fuxianhu pollution source and the feature of the agriculture and county non-point pollution considering the analogous researches inside the country and abroad. Through more than one year inspect analysis and the comparison on inflow concentration, outflow concentration, impacted circs, investment, used land, rate of decontamination, de-rate of each unit investment and the site of treatment plant, the research presents the feature with few investment, high decontamination, extensive applicability for sewage concentration, better impacted resistance, convenient supervision and manipulation cost lowliness etc. It is worthy wide generalized a technics in the process of pollution treatment for agriculture and country non-point source pollution.The research focuses on Yaonigou in the north of Fuxianhu and applies environment zoology principle and combines zoology, botany and microbiology etc all-around subjects, which provides an example for the treatment of agriculture and county non-point source pollution in the south of China.
