Causes And Countermeasures Of River Pollution In Suzhou New District

This paper selects Baiyang Bay Waterworks of Suzhou High-tech Zone,Ershui Factory of New District,Xuguang Canal,Xujiang Canal and Beijing-Hangzhou Canal as sampling tributaries,and selects the p H ?T?NH3-N?TP?TN?petroleum?volatile phenol and DO as the monitoring indexes of water quality.The water quality of different reaches in the new area is monitored and the data is analyzed to determine the influence of water quality on the water quality of Taihu Lake in Suzhou New area and to put forward reasonable treatment measures.First of all,the sampling time is 2013-2016.The mean value of different sampling points is analyzed and compared with Five types of water.The results show that TN is the most controversial parameter between different sampling points.The content of TN in the light canal,xujiang canal and beijing-hangzhou canal all exceeds the minimum requirement of five types of water bodies,ranging from 3.08 to 5.18 mg/L in 2013,from3.32 to 7.05 mg/L in 2014,from 2.9 to 4.33 mg/L in 2015,and from 2.87 to 3.64 mg/L in2016.This virtually increases the risk of eutrophication of the hu light canal,xujiang river and beijing-hangzhou canal.Secondly,the water quality of the huguang canal,xujiang river and jinghang canal was analyzed by the nemero pollution index method,which confirmed that the water quality of the water plant was clean and the water quality of the three tributaries was light pollution,and the hydrological information and water quality information of the tributary river were analyzed in detail to explore the mechanism of dissolved oxygen,temperature and total nitrogen at present.Found that xushuguan light canal-east Chu Dong newbridge,Xu Jiang-iron bridge no.1,xushuguan optical canal bridge,the grand canal-upstream bridge and chrysanthemum were computed.in xushuguan light from average TN,DO and T to T and DO as you can see the seasons change,negative correlation exists in the time span between TN trend,but is not linear relationship between the three,deserves further research.At last,through case study of lake biwa,the huaihe river water quality promotion,from 2013 to 2016 xushuguan optical canal,Xu Jiang,the phenomenon of total nitrogen in the grand canal water quality exceeds bid,puts forward the point-to-point control of industrial sources,select advantage plant building artificial wetlands to degradation of agricultural source pollution,promoting the processing effect of sewage treatmentfacilities to control pollution sources,and recommend the government try to economic tools such as public procurement,and enterprise controls to find the measures to reduce the total nitrogen in the water quality pollution,in order to jointly promote the water quality of ascension.Innovation: for the water quality of Hu Guang canal,xujiang,Jing canal,New District second water plant and white Ocean Bay water plant,The water quality monitoring and nemerow comprehensive pollution Index analysis was carried out for 4years,and the effect of total nitrogen on the key pollution index and the influence of tributaries on water quality of waterworks were analyzed.Because the water plant's water quality is better with the mixing of the existing technology and the remaining tributaries,and the measures to reduce total nitrogen pollution from tributary industrial sources,agricultural sources,sources of life,and Government and enterprise control direction are of great significance for the promotion of the water quality of Hu Guang canal,Xujiang and Beijing-hangzhou Canal tributary.
