基于模糊综合评价下河北省某工业园区水质评价

Evaluation on the water quality of an industrial park in Hebei province based on fuzzy comprehensive evaluation

基于模糊综合评价及聚类分析的方法,对河北省某工业园区污水水质进行评价。在工业园区内选定5个企业以及1个集中化污水处理厂取样,监测其COD、氨氮、p H值、挥发酚、总磷等作为评价数据,确定各监测指标的综合隶属度并判断其水质级别。结果表明,化工园区污染严重,一半处于三级污染标准。与污水处理厂进水性质相类似的有Z1、Z3等,所取6个样本显示化工园区污水主要分为2大类。

Based on the fuzzy comprehensive evaluation and cluster analysis method, the wastewater quality of a certain industrial park in Hebei province was evaluated. The water was sampled from five factories and one sewage treatment plant of centralization in the industrial park, the chemical oxygen demand（COD）, ammonia nitrogen, pH, volatile phenol and total phosphorus（TP） of the water sample were tested as the evaluation data, the comprehensive membership degree of each monitoring index was determined and the water quality level were judged. The results show that the pollution of chemical industry park was serious, the half of the sample was under the pollutant control standard grade 3. The water quality of Z1、Z3 etc. was the same as inlet water in sewage treatment plant, all the six samples show that the industrial park wastewater was classified into two kinds.
