奎河水污染现状及对策

Status Quo and Strategies of Pollution on Kuihe River

通过对奎河水污染现状的调查和相关水质项目化学需氧量(CODCr)、生化需氧量(BOD5)、溶解氧(DO)、固体悬浮(SS)、pH值和浊度等的测定,揭示了奎河水污染现状:以有机污染为主,水质劣于地表水Ⅴ类标准.对影响奎河水质的生活污水、工业废水、农业径流等因素进行分析,并有针对性地提出了治理污染的措施和有效利用水资源的方案.

By investigating the present water pollution of the Kuihe River and determinning chemical oxygen demand(COD Cr ), biochemical oxygen demand(BOD 5), dissolved oxygen(DO), suspended solid(SS), pH, degree of turbidity, the status quo of water pollution on the Kuihe River is revealed: organic pollutant is playing an important part in water pollution and the water quality is worse than the fifth level. Factors affecting the water quality are analysed, including domestic sewage, industrial waste water, agricultural runoff and so on, and the strategies preventing pollution and utilizing water resources of the Kuihe River are presented.
