垃圾中转站渗滤液处理厂工程设计
- Title:
- Engineering Design of a Leachate Treatment Plant Served for Garbage Transfer Station
- 摘要:
- 与填埋场垃圾渗滤液相比，垃圾中转站压缩出的渗滤液有机物含量高，BOD5/COD超过0.4，生物降解性较好，同时，其污染物成分相对复杂，水质水量随时间波动大。某渗滤液处理厂位于西北某城市，处理规模200 t/d，采用“中温厌氧消化+强化膜生物反应器系统（两级A/O+MBR）+纳滤+卷式反渗透”处理工艺，出水水质执行《生活垃圾填埋场污染控制标准》（GB 16889—2008）中表2要求。浓缩液采用“预处理+高压反渗透+浸没燃烧蒸发”工艺处理。实际运行表明，出水水质达到设计标准，实现了渗滤液全量化处理。
- Abstract:
- Compared with the landfill leachate, the leachate compressed from garbage transfer station has high organic content, high BOD5 to COD ratio (more than 0.4) and good biodegradability. In addition, its pollutant composition is relatively complex, and the wastewater quality and quantity fluctuate greatly with time. A leachate treatment plant with treatment scale of 200 t/d is located in a northwestern city. The treatment process consists of mesophilic anaerobic digestion, enhanced membrane bioreactor system (two-stage A/O and MBR), nanofiltration and roll reverse osmosis, and the effluent quality is required to meet the limit in table 2 specified in Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The concentrated solution is treated by the process of pretreatment, high pressure reverse osmosis and submerged combustion evaporation. The actual operation shows that the effluent quality reaches the discharge standard and the full quantification treatment of leachate is realized.
