【摘要】 报道了施用铬渣钙镁磷肥改良镉污染土壤对土壤渗漏水影响试验，结果表明在铬渣钙镁磷肥用量分别为６．６７、１３．３４和２６．６８ｇ／ｋｇ土时，土壤渗滤液未受Ｃｄ和Ｃｒ的污染，Ｐ的含量亦不会对地下水产生明显不良影响。更多还原

【Abstract】 A Calcium Magnesium Phosphate fertilizer,produced from chromium residue,was use onto a Cd polluted soil,and the influrence of the fertilizer on soil leachate was detected.The results showed that the concentration of Cd and Cr in leachates was lower than the levels of pollution.The P contants in the leachates were so low as not to give significant adverse effects on the ground water,providing the application rates of the fertilizer of 6.67,13.34 and 26.68 g/kg soil respectively.更多还原
