Unit Pollution Load Analysis Of Subsistence Drainage In The City

With the development of the industrialization and the urbanization ,the increase of the industrial and subsistence waste water ,Water pollution of the river became more and more serious. building the water quality model by zhe responded connection with point source pollution load and water quality is the important way to research the characteristic of water pollution , water environment capacity and pollution control of the drainage area. As the mostly input date, ascertain the pollution load is very important,it's accuracy decides the reliability and applicability of the output date of the water quality model.The pollution load of the city's subsistence drainage is the mostly point source pollution load which has a infection with the water quality of river,usually we ascertain the date by unit pollution load and the population of the area. So it's necessary to make sure that the date shoud have more precise and more applicable which based on the inspect of water quality and water flux to improve the simulation precision of the water quality model.Xi'an is the center of economy, seience, technology, nadedueation in the west of China. The Wei river is the chiefly river flow through the city of xi'an and also take up all the industrial and subsistence waste water. With the development of the industrialization and the population increases fastly,the point source pollution load which the Wei river received more and more,the water pollution also became more serious and water quality turn to much worsening,it has affected the sustainable development of the city of xi'an even the province of shan xi.The text chooses the high-rise house in xi'an university of architecture and technology as the inspect object,have a research to the water quality and water flux to analyse the movement rule of COD,TP,TN and NH3-N, also have a research to the characteristic of water pollution of subsistence drainage. Then we make certain the date of unit pollution load adapt to the city of xi'an by the result which we had researched. The date is pertinency and conformable to the research that make certain the point source pollution load of subsistence drainage in xi'an even all the Wei river drainage area, and it also could improve the simulation precision of the water quality model of Wei river.
