Treatment of landfill leachate by chemical precipitation-hydrolysis acidification-biology contact oxidation-reverse osmosis
摘要
Abstract
Optimal conditions of landfill leachate treatment were discussed by chemical precipitation-hydrolysis acidification-biology contact oxidation-RO combined process. Ammonia nitrogen could be removed from landfill leachate by chemical precipitation under pH = 9, n (Mg2 + ): n( NH4+): n (po34-) = 1.2: 1: 1.05, stirring speed =170 r/min, stirring time =21 minutes. Retention time was 10 h, 12 h respectively in hydrolysis acidification reactor and in biology contact oxidation reactor. Experimental results showed that the effluent quality could meet the “Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008 )”after treatment of combined technology.关键词
