摘要
Abstract
The leachate treatment project is located in Zhejiang Province,this paper focuses on the anaerobic+membrane bio-reactor(MBR)(AOAO-UF)+membrane(NF+RO)process in treatment of leachate.The designed capacity is 900 m3/d.The removal rateof effluent CODCr is 99.9％and CODCr ≤40 mg/L.The removal rate of effluent ammonia nitrogeni s 99.5％,and ammonia nitrogen ≤10 mg/L.The removal rate of TN is 99.5％,TN ≤10 mg/L and chloride ion ≤150 mg/L.The effluent meets The Reuse of Urban Recycling Water-Water Quality Standard for Industrial Uses(GB/T 19923-2005)for recirculating cooling water system.The effluent can be reused for cooling tower water supplement of energy regeneration plant.The NF unit concentration is processed in the NF unit,and the NF unit concentration is incorporated into the energy regeneration plant.The concentrated liquid produced by the RO unit enters the RO concentrated liquid unit(softening+TUF membrane+dish tube reverse osmosis membrane)for treatment,and the concentrated liquid of the RO concentrated liquid unit enters the energy recycling plant for recycling,and the effluent of the process system realizes zero waste water discharge.关键词
