Analysis of Cost Benefit of Sewage Irrigation in Kaifeng
摘要
Abstract
According to the municipal water utilization data in Kaifeng,the amount of reused sewage from agricultural irrigation,municipal,and industrial water consumption were calculated.Because the sewage reuse in agricultural irrigation involves many environmental problems,this paper analyzes the impacts of sewage irrigation on the As and Pb contents in soil,wheat quality,quality of groundwater,and health of the residents in the irrigation district.In addition,based on the basic cost-effectiveness theory,the market value method,shadow engineering method,and human capital method were selected to calculate the direct and indirect benefits resulting from irrigation.These benefits were converted to the benefit of one cubic meter of water.Finally,the net benefit of sewage irrigation was obtained by comparing the irrigation cost and benefit of one cubic meter of water,which offered the insights for the cost benefit of sewage reuse in agricultural irrigation in Kaifeng.关键词
