摘要
福州某垃圾焚烧发电厂采用预处理/厌氧/外置式MBR/RO工艺处理渗滤液,设计规模为250 m^(3)/d。运行结果表明,系统出水COD、BOD5与NH3-N分别为(47.7±18.5)、(14.6±6.1)、(0.70±0.22)mg/L,满足出水排放限值。分析污染物降解过程发现,COD与BOD5在生物处理系统(厌氧+MBR)中的去除率分别为98.7%与98.6%,MBR中的TN去除率为81.5%。这表明COD与BOD5主要在厌氧池与MBR中去除,大部分TN在MBR系统中脱除。
The combined process of“pretreatment/anaerobic/external MBR/RO”was used to treat the leachate in a municipal solid waste(MSW)incineration power plant in Fuzhou.The design treatment scale was 250 m^(3)/d.The ope-ration results showed that,the effluent concentrations of COD,BOD5 and NH3-N were(47.7±18.5)mg/L,(14.6±6.1)mg/L and(0.70±0.22)mg/L,respectively,which met the effluent water quality.The results of pollutants removal pro-cess showed,the removal efficiency of COD and BOD5 in biological treatment process(both anaerobic and MBR)were respectively 98.7%and 98.6%,and the removal efficiency of TN achieved 81.5%in MBR.Therefore,COD and BOD5 were mainly removed in anaerobic tank and MBR,while TN was primarily removed in MBR.
