广饶县河流污染带地下水水质现状评价与污染分析

Analysis on Evaluation and Contamination of Present Situation of Groundwater Quality in the Polluted Strip of Rivers in Guangrao County

多年来由于接纳上游和境内工业、生活污废水,淄河、阳河、织女河三条河流大部分时间水质为劣Ⅴ类,沿河两测形成2 km左右的浅层地下水污染带。对污染带内地下水水质现状进行评价与分析、应用模糊综合评价法进行污染程度评价。得出的结论是河流两岸浅层地下水水质由以优良或良好为主变为以较差或极差为主,污染和微污染的地下水井占81.2%,石油类、亚硝酸盐氮、氨氮、挥发酚、硝酸盐氮、高锰酸盐指数等主要污染参数超标率均在30%以上。

The Guangrao County is located in the lower reaches of some rivers. For many years, because of waste water from the upper reaches, some industries and living, the water quality of three rivers of Zi river, Yang river and Vega river is a kind of bad V. Two sides of the rivers are formed the 2km contaminated strip of shallow groundwater. The article is based on evaluation and analysis on present situation of groundwater quality in the strip. By the method of fuzzy comprehension evaluation, it evaluates degree of contamination. It is known that the groundwater quality from excellent to terrible degree, which polluted and micro - polluted groundwater well occupied 81.2% , the indexes of petroleum, nitrite, ammonia, volatilization hydroxybenzene, nitrate nitrogen, permanganate salt and other main contamination parameters are all go beyond 30%.
