摘要
通过大量国内外中水水质标准的对比,得出以下结论:国内外中水水质指标在pH值、固体悬浮物、溶解性固体、总磷、氨氮、色度等方面的要求相近或相同;在需氧有机物(BOD和COD)、细菌学指标方面存在较大差别;国内外中水应用对象方面明确性存在差别.为进一步提高我国城市中水利用率,减少中水利用对环境的负面影响提供理论依据.
A great deal of comparisons on domestic and international water quality standards of intermediate water are passed, and draw some conclusions ： The requirement of the domestic and international water quality standards of intermediate water is similar in the pH, solid suspending matter, dissolved solids, total P, ammonia nitrogen, chromaticity and so on. There were much bigger differences in the aerobic organic matters（BOD and COD）, the bacteriological index; The definiteness exists difference in application of domestic and international intermediate water.
