A Study of Water Quality Index(WQI) System for Water Supply 水源地水质评价指数系统的研究
Every effluent water quality index can satisfy the secondary standard of the integrated wastewater discharge standard ( GB8978-1996 ). 各出水指标基本都可以达到污水综合排放标准(GB9878-1996)的二级标准。
The revised drinking water quality index ( DWQI ) is scientific and practicable, which could be used to evaluate the general situation of drinking water quality. 修正后的饮用水水质指数具有很强的科学性和可操作性,可以从整体上对饮用水水质进行综合评价。
