厌氧膜生物反应器高效处理焚烧厂垃圾渗沥液
Anaerobic membrane bioreactor was used effectively to treat waste leachate
摘要
Abstract
In light of the challenges associated with disposing of high concentration organic matter in waste leachate from incineration plants,as well as issues related to microbial loss and poor effluent quality in traditional anaerobic reactors,submerged anaerobic membrane bioreactors(AnMBR)are utilized to efficiently and stably treat waste leachate.This research focused on the treatment of incinerator garbage leachate,which had an average chemical oxygen demand(COD)mass concentration of 51 065 mg·L-1.A PTFE membrane module was employed with a long-term operation at a temperature of(35±1)℃.The AnMBR demonstrated a stable COD removal rate of approximately 96％with a hydraulic retention time of 8.53 days and a volume load of(6.02±0.43)kgCOD·m-3·d-1.The highest biogas yield was recorded as 0.38 L·g-1removed COD,with the highest methane yield of 0.27 L·g-1removed COD.Due to the membrane's interception effect,the effluent water exhibited a reduction of over 99％in dissolved methane compared to the reactor's internal water quality,and a decrease of around 50％in COD.The study results demonstrated that AnMBR had the ability to resist impact load under high load conditions and could achieve long-term stable operation.The membrane module plays an important role in trapping microorganisms and improving effluent quality.关键词
