摘要
通过对长治市25个地表水断面(点位)水质的年均监测情况和月监测情况进行分析,计算出长治市市级水质时间达标率为85%,水质空间达标率为96%,水环境承载力指数为90.5%,为未超载状态。对长治市个别断面地表水监测因子氨氮、化学需氧量、生化需氧量、总磷超标进行分析,并提出治理建议和措施。
Based on the analysis of annual and monthly monitoring of water quality at 25 surface water sections(points)in Changzhi city,it is calculated that the time and space standards of municipal water quality in Changzhi city are85%,96%,and the index of water environmental carrying capacity is 90.5%,indicating that the water quality is not overloaded.In this paper,the monitoring factors of ammonia nitrogen,chemical oxygen demand(COD),biochemical oxygen demand(BOD)and total phosphorus in individual sections of Changzhi city were analyzed,and the treatment suggestions and measures were put forward.
