摘要
某城市生活垃圾焚烧发电厂一期垃圾渗滤液处理站设计处理规模为260 m3/d,采用预处理+混凝沉淀+调节池+UASB+外置式MBR(两级生化)+NF/RO工艺。介绍了处理系统的工艺流程以及主要构筑物和设备的设计参数,并对运行情况和运营成本进行了分析。结果表明,该工艺对垃圾发电厂渗滤液处理效果好,出水水质达到《城市污水再生利用工业用水水质》(GB/T 19923—2005)中再生水用作敞开式循环冷却水补充水的水质标准。出水回用作循环水补水和用于降温锅炉排污水,浓液用于飞灰增湿和烟气系统石灰制浆,全部回收利用。
The design scale of landfill leaehate treatment station of a municipal solid waste inciner- ation power plant was 260 m3/d. The combined process of pretreatment ＋ coagulation-sedimentation ＋ adjustment tank ＋ UASB ＋ external MBR （two stage biochemical） ＋ NF/RO was used. The process flow, design parameters of main structures and equipment were introduced. The operational performance and operating cost were analyzed. The results showed that the combined process had good performance on leachate treatment. The effluent quality could meet the standards of reclaimed water used as supplementa- ry water for open circulation cooling water in The Reuse of Urban Recycling Water--Water Quality Stand- ardfor Industrial Uses（GB/T 19923 -2005） . The effluent was used as circulating water to supplement water for boiler and to cool boiler blow-down water. The concentrated liquid was used for fly ash humidifi- cation and flue gas system lime vulpine. All the effluent could be recovered and utilized.
