Survey Evaluation And Division Of Rural River Drinking Water Source In Guangxi

In order to preliminary study the environmental basic situation of rural river drinking water source in Guangxi,the division of protected areas of river-type rural drinking water source,and to ensure the safety of rural drinking water,and put forward scientific and effective water source protection scheme and feasible water environment management countermeasures.This paper takes the river drinking water source of 17 villages in Lingyun County of Guangxi as the research object,and carried out the investigation of the pollution source of drinking water source,the monitoring of water quality and the division of water source protection area.Systematically analyzes the social situation of the village where the water source is located,natural environment,general situation of the water source,water supply and drainage conditions,find out the source of pollution and analyze the water quality,and use the "Guangxi Zhuang Autonomous Region drinking water source protection area division method" and arcview software to divide protection zones of drinking water source.From the management recommendations and protection measures to make corresponding recommendations for drinking water source.The main results of this paper are as follows:(1)The pollution status of drinking water source:The main pollution source is the non-point source pollution,which is based on rural life pollution and farmland runoff pollution.(2)The results of water quality evaluation of drinking water sources:The fecal coliform of Chaoli Township Nine village of Nahe tun monitoring points?Ling Station Township Jiu Min Village of Bailao Tun monitoring points?Ling Station Township Lingxing Village of Potie Tun monitoring point?Jiayou Township Xiasan village of Sanli Tun monitoring points?Yuhong Township Shangmou village of Baguan Tun monitoring points?Luolou Township,Bulin Village of Bulin Tun monitoring points have exceeded the standard,the rest of water source monitoring factors are all up to standard.(3)Using empirical analogy method and Arcview software to divide the protection zones of drinking water source and determine the boundary of water and land.(4)Analyze the management advice and protection measures,including Including the establishment and improvement of management organizations,the implementation of the relevant laws and regulations,the establishment of a complete water quality monitoring system,the establishment of water sources emergency plan,pollution remediation project,farmland runoff control project,Water conservation forest project,rural clean energy alternative project,isolation protection project,setting landmarks project,to ensure the safety of protection zones of the water source,also provide reference for similar areas.
