摘要:环境是指周围存在的条件,总是相对于某一中心事物而言的。人类依存于环境,受其影响,另一方面又在发展中改造了环境,影响环境。环境影响评价是所在建项目对周围环境的影响,而很少以地区为中心进行环境影响研究。因此,环境影响评价中存在一些缺陷。本文通过对环境污染物进行检测和分析从而对区域内的环境质量进行评价。论文通过水质的实地检测对数据进行处理,分析与评价环境质量现状。进行多次反复试验,以确保试验的科学性和可靠性。经试验得出大学城内的水环境质量超标严重,可采用引水稀释或加入化学药剂引水回流等措施整改,但要解决这个问题,还是要从源头出发。4359

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.
