Poyang Lake Littoral Zone Industrial Water Pollutant Emission Condition Research

Poyang Lake is an important wetland in China,is an important ChangJiang River Regulation and storage lakes in ChangJiang River Chinese play a huge flood storage and conservation of biological diversity and other special ecological function,is one of the ten major ecological function reserve in our country,one of the most important ecological areas worldwide is delimited by the world Wildlife Fund,it is important to the role of maintaining regional and national ecological security.Over the past 30 years,industrialization continues to accelerate,the main river water system across the country are facing the problem of pollution,Poyang Lake overall water quality remained in the nutrition level is better than the other four major freshwater lakes,but in recent years the decline significantly,effects of pollution load of industrial development in Poyang Lake City and produce on the lake is increasing.Therefore,the study of industrial water pollution in Poyang Lake area is of great practical value to understand the pollution status of Poyang Lake and to control the pollution.This article through to the Poyang Lake Lake on-the-spot monitoring,to obtain relevant data,data collection,collation,summary and analysis,to find out Poyang Lake Lake industrial pollution source(wastewater)of major pollutants and emissions and emission channels:1.More than half of the surveyed enterprises,Poyang Lake focused on the Castle Lake,Xinjian County,Fengcheng,Nanchang County,Leping City,Jinxian County,the survey enterprise wastewater through the main Ganjiang River in Poyang Lake,mainly concentrated in manufacturing chemical raw materials and chemical products industry survey enterprises and non-metallic minerals three manufacturing industries.2.Poyang Lake area more than and 400 industrial enterprises have wastewater treatment facilities,wastewater treatment facilities amounted to more than and 500 sets of 16072 area control facilities and operating costs increased year by year,COD and ammonia emissions corresponding to effectively reduce the.3.5municipalities and districts in Nanchang city industrial wastewater and pollutant emissions,the largest study of regional pollutant emissions statistics of districts and counties of Nanchang Qingshan Lake industrial wastewater and pollutants emissions are mainly concentrated in the Castle Lake,Changjiang District,Leping city and Mount Lu area,the contribution rate of more than 50%.Distribution:the contribution of watershed pollutant emissions in Poyang Lake basin of Ganjiang River,Raohe rate of more than 60%.Industry distribution:industrial wastewater of papermaking and paper products industry is the largest,chemical raw materials and chemical products manufacturing COD and ammonia emissions,total emissions from the largest food manufacturing industry,the total nitrogen emissions industry is the largest pharmaceutical manufacturing industry,4?from the research results,the discharge of wastewater is still growing,but in recent years,due to pollution control inputs,the discharge of industrial waste water in Poyang Lake has a significant downward trend.
