Test and Analysis of Environmental Pollutants in Fengxian University Town
Abstract: Environment refers to the existing surrounding conditions, which is always relative to a center. Human beings rely on the environment, on the other hand, under its influence, reform and affect the environmental in the process of developing. Environmental impact assessment is the effect on the construction project on the surrounding environment; however few research on the impact of environmental by the center of area. Therefore, the environmental impact assessment process has some defects. The paper carries on processing to the data through the field detection of water quality, analysis and evaluation present environment quality. To ensure the scientific and reliability of the experiment, we experiment repeatedly. The experiment indicates that the University City water environmental quality beyond the standard seriously, we can solve the problem by diluting water or adding chemical agent and backflow in water. To solve the problem, we need to control the sources.
Keywords: environmental impact assessment; pollutants; test and analysis
