Groundwater Environment Quality Assessment And Characteristic Pollutants Analysis In Heilongjiang Plain

Since reform and opening up, with social and economical development of Heilongjiang province, the demand of groundwater in small town is increased in Heilongjiang Plain area. The irrational exploitation of groundwater and constant increase of sewage discharged in industrial, agricultural, residential area caused the aggravation of polluting groundwater and the deterioration of groundwater quality.Therefore, synthetically assessment the groundwater in small towns in the Heilongjiang Plain area and systematic study and analyze the condition of groundwater quality to determine the level of contaminated groundwater becomes very important and practical significance to groundwater resource protection, pollution control and water resources policy formulation. The following aspects of small towns in Heilongjiang Plain area is deeply studied in this paperby collecting various types of information and access to relevant literature on the basic situation of the study area to do a more detailed formulation. Including geography, transport, socio-economic situation, the main environmental problems and geological conditions, hydrogeological conditions. Went to the study area small towns, got water samples that can represent the local water condition, back to school, after a series of standard test, check out all kinds of water quality indicators which was in the local water. The results showed that the water quality of the data was fundamentally in accordance with local water quality. Synthetically evaluated groundwater environment in the study area, three methods were adopted in this paper-plus the score note, fuzzymath evaluation method and superiority evaluation method to evaluated the condition of groundwater in small towns in Heilongjiang Plain area.and got the situation of groundwater quality evaluation results in study area Analyzed the local the main influencing factors in groundwater quality, and analyzed the advantages and disadvantages of the three evaluation methods. Finally to the quality of groundwater for the study area, the corresponding control measures and recommendations was given in the last of this paper.after the systematic and comprehensive evaluation of the study area groundwater environment, according to local social and economic situation and the results of this study to determine the characteristics of local pollutants.systematically analyzed Distribution and characteristics of pollutantsFinal results showed that the three plains of Heilongjiang Province-Songnen Plain, Sanjiang Plain, Muling-Xingkai Plain's groundwater quality is generally poor, the quality of groundwater level was more likely shown asâ…£,â…¤.In this three Plain, the groundwater quality of Sanjiang Plain was slightly better than that of the Songnen Plain and Muling-Xingkai PlainThe realization of the three assessment methods are based on MATLAB in this paper, implemented the computer assessment of groundwater quality, greatly reducing the workload and shorten the assessment time.
