| 摘 要： | 针对垃圾渗滤液的氨氮、COD、难降解物质浓度高等特点，开发了磷酸铵镁沉淀法（MAP）脱氮一厌氧／好氧生物处理一混凝组合工艺处理垃圾渗滤液的新技术，研究了不向单元的作用及影响处理效果的因素。实验结果表明：高浓度垃圾渗滤液经组合工艺处理后，其COD、BODs、NH3-N、E260（紫外260nm处吸光度，代表难降解有机物）的去除率分别为97．5％、99．29／5、87．2％、75．3％。

| Abstract: | A multi-stage wastewater treatment process was developed for treating high strength sanitary landfill leachate. Magnesium ammonium phosphate was employed in the first stage precipitation treatment to remove a major portion of the ammonia nitrogen present in the leachate; low oxygen/aerobic biological treatment in mixed reactors was then performed to remove biodegradable organic pollutants ; coagulation and flocculation treatment was performed at the last to produce a dischargeable final effluent. In the test case, COD was reduced from 10 300 to 256 mg/L and that BOD was reduced from 3700 to 28mg /L. |
