中文摘要：
研究了用絮凝法去除垃圾渗滤液中污染物及其对垃圾渗滤液毒性的影响。试验结果表明，浓度为12mmol/L、pH值为8的硫酸铁对NH3-N的去除率达到61．3％；pH值为8的聚合硫酸铁和pH值为7．47的聚硅硫酸铁也能有效去除垃圾渗滤液中的有机污染物和重金属。毒性试验显示，pH值为8的硫酸铁对甘蓝种子萌发的影响最小，与自来水相比没有显著差异，有效地降低了垃圾渗滤液的毒性。
英文摘要：
Landfill leachate containing NH3-N,organic contaminant and heavy metals would result in serious risks to ecosystems if these chemicals were not treated efficiently. In order to decrease or eliminate their harmful effect, flocculation processes were carried out to remove NH3-N,organic contaminant and heavy metals from anaerobic-aerobic landfill leachate. The experimental results indicated that ferric sulphate was superior to the other coagulants and 61.3% of NH3-N was removed at an optimum dosage of 12mmol/L at pH=8. Organic contaminants and heavy metals were also removed effectively with polyferric sulphate at pH =8 and polyferric silicate sulfate at pH=7.47. Toxicity tests showed that ferric sulphate at pH=8 had little effect on the germination of carbage seed, and toxicity of landfill leachate was reduced significantly.
