Assessment Of The Quality Of Water Resources In Zhengzhou City Proper

Partly unqualified water quality, population boom and city development, plus low and uneven rainfall, lead to problems in Zhengzhou water resources although it is close to the south bank of Yellow River. Therefore, it is a necessity to carry out research on Zhengzhou water resources due to the expanding city scale and underdeveloped basic facilities.The dissertation mainly deals with analysis and evaluation on the quality of Zhenghzou water resources. From the natural condition and social zhengzhou city regional features of economy of zhengzhou city, surface water and groundwater used the assessment, and groundwater resources in water resource and with a single index method, integrated pollution index method etc qualitative and quantitative evaluation of water resources, made clear the current water conditions; Zhengzhou 6 river water to zhengzhou nine sections of the monitoring analysis of water quality, using a single factor after the evaluation method, zhengzhou surface water of river water situation while it is standard, but part of the material to excess levels, means that part of the river there exists different degree of pollution, have related material IV light pollution of the water, there are also related material V kind of water pollution, has to exceed bid; Using the integrated pollution index method, through evaluated by standard, the water IV classes and V for comprehensive evaluation of water, from the analysis on water quality in, in pollution state, more adjacent at V class water.Making evaluation on the quality of Zhenghzhou underground water according to the analysis on the monitoring datas of thirteen explored underground water. Try to employ the combination method of single factor evaluation and comprehensive evaluation method, II class water could reach the standard, the rest of the fine can be achieved III class water good standard of zhengzhou city, relatively superior quality of groundwater quality surface water, but some areas exist inferior water such as high fluorine, etc.Drinking water supply water to Zhengzhou centralized evaluated from water source, water, water quality evaluation and assess the water eutrophication status evaluation of the three aspects of drinking water, at present are Zhengzhou centralized standards. The urban population increases unceasingly, drinking water safety and stability must be of problem to solve, drinking water supply situation, in particular to drinking water supply water of zhengzhou city made analysis evaluation; Finally and analyzes the water supply and water balance in zhengzhou, and analyze the relationship between predict the future for nearly 10 years, and zhengzhou water to consider how to supplement water problem. WinThe dissertation advocates effectively developing and using water resources in the base of balance between supply and demand, additionally, it proposes effetive plan to use water resources. More new sewage handling factories need to be built to deal with polluted water in life and industry, then making the water qualified for usage. All these methods can largely improve the water quality, besides, the handled water can be used for scenery ecology.Based on the series of analysed results, this dissertation not only gives conclusion eventually, but also puts forward prospect and reasonable suggestions.
