Study On The Situation And Management Countermeasures Of Rural Sewage Treatment In Ninghai County

The implementation of rural revitalization strategy is a major decision made by the 19^th CPC National Congress.In June 2018,the CPC Central Committee and the State Council issued“the opinions on comprehensively strengthening ecological and environmental protection,and resolutely fighting pollution prevention and control”（Issued by the CPC[2018]NO.17）,proposing to“fight the battle against agricultural and rural pollution governance”.In 2014,Zhejiang province launched“five water co-governance”project with emphasis on the treated sewage,on the basis of construction project of“Thousand village demonstration,ten thousand village renovation”（2003）The basic and key work was rural domestic sewage governance,and it achieved remarkable achievement,but also faced with some problems and difficulties,which needed to continuously explore and improve.This study takes Ninghai county of Zhejiang province as a case to analyze the treatment of rural domestic sewage,summarizes and analyzes the governance effect and main problems,and puts forward management countermeasures.The research process and conclusions are as follows:（1）On the basis of field investigation,it analyzes characteristics and standard of rural domestic sewage discharge.Sewage discharge characteristics include flushing toilet sewage,laundry sewage,kitchen sewage and bath wastewater,which constitutes the main source of rural domestic sewage.The research analyzes rural domestic sewage disposal mode（factory processing,relatively concentrated processing,decentralized processing,farmer processing）and run maintenance mode（village-level personnel operation mode,professional personnel operational mode,sewage treatment plant operational mode）.（2）Based on the Kuznets curve,externality theory and other theories,and based on survey data and second-hand data of 174 households in 12 villages,the results of rural sewage governance are summarized and analyzed,including improving water quality,and sewage governance rate reaching87.5%.Village appearance has been significantly improved,and satisfaction evaluation before and after governance of rural sewage has been improved by 49%.At the same time,the main problems in rural domestic sewage governance are analyzed in depth,which are mainly reflected in the lack of attention paid to it by various departments and towns at all levels,multiple constraints such as capital and technology,objective reasons such as low educational background,old age and weak management ability of managerial personnel,and low level of sewage governance technology.（3）Based on different level,such as farmers,village-level and government,the research puts forward management countermeasure and security measures to promote long-term governance of rural sewage in the light of local conditions,including:playing the main body role of villagers,the perfection of sewage running maintenance mechanism,ensuring sewage maintenance fund,increasing technology innovation of domestic sewage governance,and strengthening propaganda of sewage governance.
