摘要
针对重庆市某污水处理厂A2/O工艺协同处理垃圾渗滤液正常运行的要求,考察曝气吹脱法、MAP法、矿化垃圾法预处理渗滤液对其氨氮、COD的去除效果,同时通过对处理前后有机物相对分子质量分布的对比并综合经济比较表明,采用矿化垃圾法预处理渗滤液,不仅可以去除50%～60%氨氮、40%～50%的COD,以及大分子有机物,降低对污水厂的冲击危害,而且运行费用低廉,是较为经济有效的垃圾渗滤液预处理技术。
Pointing to the requirements of A2/O collaborative treatment of Landfill Leachate in the sewage treatment plant in Fuling of Chongqing.investigated the COD and ammonia nitrogen removal efficiency after treating by aeration stripping,MAP and aged-refuse,compared the distribution of organic molecular weight before and after treatment,and combined with economic comparison.The results showed that,aged-refuse press can not only remove 50%～60% ammonia nitrogen,40%～50% COD,and effectively remove macromolecular organic compounds,reducing the harmful impact to sewage plant,at the same time,the operating cost was low.So it was a more cost-effective pretreatment of landfill leachate.
