Water Quality Status And Improvement Apporoaches Of Diaodeng Rive In Dadukou District,Chongqing

Since the reform and opening-up,the economy of our country,China,has made surprisingly progress.Meanwhile,the resource consumption is on the rise.The continuous improvement of residents’living standards needs consuming a great deal of resource and residents’eagerness for a better life accelerates urbanization in China,which results in large consumption of resource and wide possession of private cars.All these contribute to waste emissions,which the environment is impossible purify.The direct emission of wastes into the water has a bad influence on water body,and the solid wastes will finally go into the water body with rain,as well as air pollution with deposition.It is in the 18^th National Congress of the Communist Party of China that the construction of ecology civilization was put forward,from which the construction of ecology civilization has become the focus of personages of all circles.Also,the construction of water ecological civilization city is a must way to city development,a necessity to sustainable development.The proposal of the construction of water ecological civilization city lights the process of urbanization,providing a new and creative way.The construction of water ecological civilization city remains the precondition of human existence and development,so that protecting our water resources is of fundamental importance.As a country with water shortage,the amount of the water resource occupation per person in China is far below that in other countries,the construction of water ecological civilization city is even more essential.The aim of its construction is to protect water resources,improve water quality,and balance development and protection of water,creating an atmosphere where we can live with nature in harmony.So all in all,what we need to focus on is that we should respect natural law and create an ecological civilization city with joint efforts.Here,I will set about carrying out the construction of water ecological civilization city in Dadukou District.The paper,studying the Tiaodeng River in Dadukou District,Chongqing,analyzes the current situation of its water quality and puts forward corresponding measures for the problems found.According to the analysis,I draw conclusions as follows:1.Before September 2017,the river quality in Tiaodeng River exceeds V class,serious pollution.As we began to renovate it,it is better now,but still remains V class.2.The water quality in Tiaodeng River is mainly influenced by COD(32.20±7.72 mg·L^-1),Phosphorus(0.43±0.18 mg·L^-1),Ammonium Nitrogen(2.30±1.47 mg·L^-1),Fecal Coliform(24688±5443 mg·L^-1).The discharge of industrial wastewater and sanitary sewage is the main reason for the worsening of its water quality.3.The investigation reveals that the citizens,lacking environmental awareness,never completely dissolve sewage,and that the renovation of water conservancy remains to be finished effectively.4.With the construction of water ecological civilization city,many measures have been taken.At the same time,many problems about water environment protection are exposed,for example,the water conservancy project and its preservation are not up to standards,citizens lack environmental awareness,the policy about the construction of water ecological civilization city hasn’t been perfected and so on.5.As for the problems found,I suggest strengthening law enforcement and management,increasing publicity efforts,completing relevant policy,speeding up the process of restoration work of water eco-environment,and enhancing the administration of water pollution.
