摘　　要：本文引入模糊综合评判方法,建立了水质评价的模糊综合评判法模型。结合柳林地区采排水水质分析数据,对该区煤层气井采排水水质进行了评价,研究表明,该区煤层气井采排水水质为Ⅴ类水,其中氨氮和氯离子含量为水质划分主要的影响因子,建议进行处理后再排放。Since the fuzziness and uncertainty of water quality analysis data classification,in order to effectively evaluate the quality of water drained from CBM well,this paper introduces the fuzzy comprehensive evaluation method and establishes the fuzzy comprehensive evaluation model of water quality evaluation. Based on the analysis data of drained water quality in Liulin area,the quality of water drained from CBM wells was evaluated. Studies have shown that the quality of the drained water is Ⅴ class,thereinto the contents of ammonia nitrogen and chloride ion are the main impact factors of water quality classification. It is recommended that the drained water should be disposed before discharge.
