基于指數法和模糊綜合評價法對盤龍鉛鋅礦區的水質分析與評價
首發時間:2023-09-04
摘要:為了研究廣西盤龍鉛鋅礦區水質污染情況,使用指數法和模糊綜合評價法,分別對選取的12處地表水和14處地下水水質數據進行分析與評價。指數法結果表明,1處地表水監測斷面的水質呈重度污染,主要污染因子為總磷、鐵和錳,分別超出地表水III類標準限值的3.27、2.31和5.84倍;1處地表水監測斷面的水質呈輕度污染;其余監測斷面的水質良好。模糊綜合評價結果表明,礦區地下水水質在I~III類水范圍,其中,42.86%的地下水水質為I類水,18.75%的地下水水質為II類水,31.25%的地下水水質為III類水。III類地下水主要分布在盤古和尾礦庫周圍,主要污染因子包括砷、鉛和鎘。

Analysis and evaluation of water quality in Panlong Lead-zinc mine based on index method and fuzzy comprehensive evaluation method
Abstract:In order to study the water pollution situation of the Panlong lead-zinc mine area of Guangxi, the water quality data of 12 surface waters and 14 groundwaters were analyzed and evaluated using the index method and the fuzzy comprehensive evaluation method. The results of the index method show that the water quality of one surface water monitoring section is severely polluted, and the main pollution factors are total phosphorus, iron, and manganese, which are 3.27, 2.31, and 5.84 times higher than the limit of surface water III standard, respectively. The water quality of one surface water monitoring section is slightly polluted. The water quality of other monitored sections is good. The results of the fuzzy comprehensive evaluation show that the groundwater quality of the mining area is in the range of class I~III, of which 42.86%, 18.75% and 31.25% of the studied samples can be indexed to class I, II andIII water, respectively. Class III groundwater is mainly distributed around Pangu and tailings pond, and the main pollution factors include arsenic, lead, and cadmium.
