混凝沉淀-吹脱- Fenton氧化协同预处理垃圾渗滤液膜滤浓缩液的研究
Treatment of Concentrated Leachate from RO System Using Coagulation, Ammonia Stripping and Fenton Oxidation Processes
摘要
Abstract
[Objective] The research aimed to study the control of concentrated leachate with method of coagulation, ammonia stripping and Fenton oxidation processes. [ Method] A treatment process for the concentrated landfill leachate from a reverse osmosis equipment using coagulation, ammonia stripping and Fenton oxidation was developed. The effects of the composite coagulants, ammonia stripping temperature, pH, quantity of flow air, H2O2 and Fe2+ concentrations on COD and NH3-N removals were investigated. [ Result]The results showed that the optimum efficiency of coagulation and ammonia stripping could be achieved under the profiles of 6 g/L MgO and 2 g/L Ca(OH), by agitating for 24 h followed by blowing air at the speed of 6 L/(min ? L) for 4.5-5.0h at pH of 11.0-11.5. The optimistic conditions of orthogonal tests were H2O2 concentration 750 mmol/L, Fe2+ concentration 28 mmol/L, reaction time 45 min, pH 3. COD and NH3-N removal rates were 93.4% and 95.7% through the whole process. [Conclusion]This research indicated that the control of concentrated leachate with method of coagulation, ammonia stripping and Fenton oxidation processes was ideal and should be studied for next step.关键词
