- 摘要:
- 老龄化填埋场渗滤液氨氮浓度高、可生化性差、C/N比失调，以某老龄化垃圾填埋场渗滤液和垃圾焚烧厂渗滤液协同处理工程为例，详述两种渗滤液全量化处理系统。填埋场渗滤液设计规模1 500 m3/d，焚烧厂渗滤液设计规模500 m3/d，采用“厌氧系统+两级A/O+外置式超滤+纳滤+反渗透”处理工艺，纳滤浓缩液采用“物料膜减量化+臭氧氧化”处理工艺，反渗透浓缩液采用“DTRO减量化+浸没燃烧蒸发”处理工艺。工程投资一类费3.6亿元，运行成本101.20元/m3。项目建成运行至今，出水稳定达到《生活垃圾填埋场污染控制标准》（GB 16889—2008）表2标准。通过两种渗滤液的协同处理，可减少碳源投加量，节省运行成本，同时实现渗滤液全量化处理，浓缩液不外排。
- Abstract:
- The leachate from aging landfill is characterized by high ammonia nitrogen, poor biodegradability and imbalance of C/N ratio. This paper elaborated the full quantitative treatment process of two kinds of leachate in detail exemplified by a synergistic treatment project of leachate from an aging landfill and a waste incineration plant. The design scale of leachate from the landfill is 1 500 m3/d, and that of leachate from the incineration plant is 500 m3/d. The main process consists of anaerobic system, two-stage A/O, external ultrafiltration, nanofiltration and reverse osmosis, the treatment process of nanofiltration concentrate is material film reduction and ozonation, and that of reverse osmosis concentrate is DTRO reduction and submerged combustion evaporation. The project investment is 360 million yuan, and the operating cost is 101.20 yuan/m3. Since the completion of the project, the effluent quality has stably reached the limit in table 2 specified in the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The synergistic treatment of the two kinds of leachate reduced the dosage of carbon source and saved the operating cost, and achieved full quantitative treatment of leachate without concentrate discharge.
