摘要
污水处理厂处理污水的能力直接决定一个地方的环境质量,并对人们的健康产生直接的影响.因此,对于经污水处理设施处理过的污水进行水质检测及分析就显得尤为关键.本文选择武夷山市具有代表性的污水处理厂,2014年～2020年的进、出水水质指标进行了分析统计.为了更加科学、全面地评价污水处理厂的水质质量,本研究提出采用单因子指数评论法、综合污染指数法、分级评价法、内梅罗指数法,基于2014 年～2020年BOD5、CODCr、pH、NH3-N、SS等 5 个水质监测指标数据,对污水处理厂水环境水质进行动态分析和综合评价,研究结果均表明污水处理厂出水水质质量均达到排放标准,4种评价方法均能较好地反映污水处理厂的水环境状态.
Abstract
The ability to deal with Sewage Treatment Plant directly determines the environmental quality of a place and directly affects the public's health.Therefore,it is particularly important for sewage treatment and analysis of sewage treatment plants through sewage treatment plants.In this article,the representative Sewage Treatment Plant in Wuyishan City has been analyzed and statistics.In order to more scientific and comprehensively evaluate the water quality of the Sewage Treatment Plant,four commonly used single-factor index review methods,the combined pollution index method,the hierarchical evaluation method,and the Nemero index method were selected for this study.Based on the monitoring data of BOD5,CODCr,pH,NH3-N,SS from 2014 to 2020,the dynamic analysis and comprehensive evaluation of water environment quality in Wuyishan Sewage Treatment Plant was carried out.The results show that the water quality of Wuyishan Sewage Treatment Plant is excellent,and four evaluation methods are used.It can better reflect the water environment status of Wuyishan Sewage Treatment Plant.
