【摘要】 在对垃圾填埋场渗沥液污染物的转化、溶出规律分析的基础上，建立了污染物溶出模式和污染物负荷计算模式，并结合苏州七子山垃圾填埋场的实际情况，确定了其渗沥液在不同条件下的水质。研究表明，在填埋场填埋稳定期的枯水期和丰水期的ＣＯＤｃｒ和ＢＯＤ５浓度分别为２７．２４～４０．８６ｍｇ／ｌ、１３．１７～１９．７５ｍｇ／ｌ和１３．４６～２０．２１ｍｇ／ｌ、６．５１～９．７７ｇ／ｌ；在填埋场封场后枯水期和丰水期的ＣＯＤｃｒ和ＢＯＤ５分别为４．８８～７．３３ｇ／１、２．３６～３．５４ｇ／ｌ和２．２２～３．３４ｇ／ｌ、１．０８～１．６１７ｇ／ｌ。更多还原

【Abstract】 Based on the analysis of transforming and dissolving processes of leachate from landfill site,the paper put forward the dissolving and load models of pollutants, and calculated the concentration of leachate under different conditions according to the practical situations of Qizishan landfill site in Suzhou.The results showed that COD_cr and BOD₅ concentration of leachate during dry season and rainy season are 27.25～ 40. 86g/l , 13. 17～ 19. 75 g/l and 13. 46～20. 21 g/l , 6. 51 ～9. 77 g/l ,respectively before the landfill site is closed ;and 4. 88～7. 33 g/l, 2. 36～ 3. 45 g/l and 2. 22～ 3. 34 g/l , 1. 075～ l. 617 g/l ,respectively after the landfill site is closed.更多还原
