Research on the condition of environmental quality and pollution prevention in Yinchuan

运用环境科学的基本理论,分析了银川市的环境空气质量状况,城市噪声功能区的划分与噪声源的现状,银川市水环境的状况和主要排水沟的现状及固体废弃物的排放、利用情况.指出银川市环境空气质量中的主要污染物质是总悬浮颗粒物,及造成此种污染的原因;说明银川市的城市噪声源是随着城区面积的扩大,活动人群的密集,噪声幅度的增加而小幅增加的.由于水资源的需求快速增长,污染物的排放及措施的不力,使水资源面临多方压力.造成水质的主要污染因子是氨氮;水质污染类型为有机污染、无机盐类污染;银川市固体废弃物的产生量为全区第三位,工业固体废弃物综合利用率为全区首位.提出了银川市环境质量污染的防治措施.

Based on the basic theory of environm ent science,the paper analyzes the p resent environmental atmosphere quality the water environment,main catchments ditch,and the and use of solid pollnt ants;points out the major polluted m atter is TSP grain and the cause;and it is indicated that the source of noise increases with t he expansion of city area,the gathering of moving people,and the span of noise.The rap id increase in water resource,of wastes,and the ineffectiveness of matc hing measures make water resource under various pr essures;the main polluting element in water are ammonia and nitrogen;th e types of water pollution are organic pollution and machenical;salt pollution the prod uction of solid pollutants in Yinchu an is the third,and the comprehensive useage of industrial solidwastes is the first.The paper a lso puts forward some measures to pre vent the pollution of environment quality.
