五台山风景区水化学特征与评价

STUDIES ON THE CHEMICAL CHARACTERISTICS AND EVALUATION OF WA-TER IN WUTAI MOUNTAIN

本文研究了五台山水体COD、DO、pH和硬度等基本性状及Cu、Zn、Cr、Ni、Ph、As、Cd、Hg等9种化学元素的含量状况,进行了水体基本性状元素含量以及元素间的相关分析,并对水环境质量进行了评价.结果表明:五台山地表水质较好,被测的9种元素都在一般河流的含量范围之内,水环境质量指数为0.272,属尚清洁水平.

Basic properties, such as pH. hardness, COD, DO, and contents of Cu, Zn, Cr, Co, Ni, Pb, As, Cd and Hg, and their distrbutions of water in Wutai Mountain were studied. According to the Standard of Surface Water Environmental Quality of P. R. China, environmental quality of water was evaluated with comprehensive quality index. The results showed: the contents of nine elements were in the rang of general rivers Contents of Cu. Pb. Ni were the highest at the middle reach of Qingshui River. Comprehensive quality index was equal to 0. 272. Water environment was good on the whole.
