摘　　要：随着社会的进步,人们的生活水平有了显著提高,对生活饮用水的质量要求也在不断增加,因此承担主要供水职责的水库的水质检测对人民生活而言意义重大。本文以庄河市转角楼水库为例,选取了7种水环境污染指标(生化需氧量,高锰酸盐指数,氨氮,总磷,总氮,六价铬,以及氰化物)作为评价依据,在综合各种污染因子影响程度以后,利用增加权重后的模糊数学综合评价法,较为严谨客观的反映了庄河市转角楼水库的水质状况,经评价,该水库的供水水质为Ⅱ类,符合当地水质评级。运用灰色理论GM(1,1)预测模型,计算平均相对误差值对模型精度检验,经检验,模型较好,具有使用价值。此研究可用作其他地区水库水质评价参考。With the progress of society,people's living standards have been significantly improved,and the quality requirements for domestic drinking water are also increasing,so the water quality testing of reservoirs that bear the main responsibility for water supply is of great significance to people's lives.In this paper,taking the Zhuanjiaolou reservoir of Zhuanghe city as an example,7 kinds of water environment pollution indicators(biochemical oxygen demand,permanganate index,ammonia nitrogen,total phosphorus,total nitrogen,hexavalent chromium,and cyanide)were selected as the evaluation basis,and after the degree of influence of various pollution factors,the fuzzy mathematical comprehensive evaluation method after increasing the weight was used to more rigorously and objectively reflect the water quality of the corner tower of Zhuanghe city,and after evaluation,the water quality of the reservoir was class II,in line with the local water quality rating.The Grey Theory GM(1,1)prediction model is used to calculate the average relative error value to test the accuracy of the model.The test shows that the model is good and has practical value.This study can be used as a reference for water quality evaluation of reservoirs in other regions.
