Study On Existing Problems And Countermeasures Of Water Pollution Control In Liuyang River

The green development concept of “Green Mountain is invaluable asset” has been highly praised in China for a long time.However,due to more problems accumulated in the previous economic development,and extensive development methods have not yet fundamentally changed,the ecological quality of all river basins in China is widespread.Not high,water pollution is very serious.Since the 21 st century,especially during the implementation of the “11th Five-Year Plan”,“Twelfth Five-Year Plan” and “Thirteenth Five-Year Plan”,sewage treatment has been an important part of the promotion of environmental protection undertakings,and has led to urbanization and ecological civilization construction in China.The process is significant.At present,China's urban sewage treatment has achieved a leap-forward development.China has become the world's largest sewage treatment country,and the water quality of the country has been continuously improved.However,due to the impact of economic development,technological processes,and other aspects,China's wastewater treatment has significant room for improvement in terms of concepts,methods,and techniques.The pressure on the target is huge.Therefore,under the background of pursuing green,green and green development,how to guide and optimize the development of wastewater treatment has become an important issue that all levels of governments in China need to pay attention to.As a primary tributary of the mother river of Hunan Province-the Xiangjiang River,Liuyang River was known as the "Nine of the Eight Curves".In recent years,a large amount of wastewater and domestic sewage generated from industrialization and urbanization have been discharged into the Liuyang River,causing the water quality of the Liuyang River to continuously decline and the water resources to be in short supply,which has an impact on the production and life of local residents.In 2015,the national “Water Pollution Prevention Action Plan” was promulgated.It was an important goal for all levels of government's public management to put emphasis on the fight against environmental pollution and realize the harmonious coexistence of humans and nature.Under the guidance of national policies,the “13th Five-Year Plan for Ecological Construction and Environmental Protection of Changsha City(2016-2020)and the Implementation Plan for the Compliance of the Liuyang River Water Body in Changsha City in 2017 will be launched in succession to provide opportunities for the wastewater treatment of the Liuyang River.From the process of wastewater treatment in Liuyang River,the status quo and characteristics of wastewater treatment were studied.Problems and causes of wastewater treatment in Liuyang River were analyzed.Suggestions for improving the pollution control efficiency of Liuyang River were proposed,which are conducive to promoting the supply of public water resources.The side structural reforms will increase the utilization rate of established sewage treatment equipment and reduce the loss of state-owned assets.It will also help achieve a green,coordinated and sustainable development of the water ecological environment and promote the maximization and equalization of the watershed's overall interests.Therefore,it is of great significance to analyze the practical difficulties of sewage treatment in Liuyang River and to explore the practical obstacles to sewage treatment in Liuyang River.There are six parts in the full text.The specific framework and main content are as follows:The first part is introduction.This section mainly elaborates the background and significance of the topics selected,research ideas and methods,and aims to provide theoretical guidance for the problems existing in the water pollution control of Liuyang River and the countermeasures.Secondly,the current status of relevant theoretical studies on water pollution control at home and abroad was introduced.The second part defines the basic concepts and outlines the basic theory.First,the concepts of water pollution in river basins,water pollution control,and water pollution control in river basins are defined separately.Second,relevant theories of government public service management are summarized,including the overall governance theory,public goods theory,and principal-agent theory.The third part analyzes the pollution control of Liuyang river basin.The paper introduces the environmental profile,socio-economic profile and water pollution profile of the Liuyang River Basin respectively.At the same time,it summarizes and summarizes the water pollution control of the Liuyang River,laying the foundation for the analysis of pollution problems in the Liuyang River.In addition,it introduced and analyzed the significance of the treatment of sewage in the Liuyang River Basin and hoped to fully mobilize all sectors of society to take active actions to jointly treat pollution in the Liuyang River Basin.The fourth part introduces the problems and causes of water pollution in Liuyang River Basin.We have found that the government's efforts to curb pollution,the insufficiency of pollution control tools,and the continuous prohibition of farmers and aquaculture pollution on the ground are not only the difficulties faced by the Liuyang River water pollution management.The reason for this is due to the fragmentation of the administrative division and the lack of an overall governance body;the lack of policy funds and the imperfect safeguards for pollution control;Inadequate environmental regulations,difficulty in promoting the investigation of pollution sources.The fifth part of the Liuyang River water pollution control strategy recommendations,through drawing lessons from the experience of the United Kingdom,Germany,Japan,the United States in the river basin water pollution control,put forward Liuyang River water pollution control quality and efficiency increase countermeasures.The sixth part concludes and discusses.
