- 摘要:
- 垃圾焚烧发电厂产生的渗滤液具有污染物成分复杂、水质水量波动大、有机物和氨氮浓度高、处理难度大的特点，以国内某垃圾焚烧发电厂450 m3/d的渗滤液处理项目为例，针对垃圾焚烧发电厂渗滤液的特点，采用UASB+A/O+MBR+两级RO组合处理工艺，确保处理后出水稳定达到《生活垃圾填埋场污染控制标准》(GB 16889—2008)。RO浓缩液采用高压管网式反渗透(STRO)减量化处理后回喷焚烧炉。近两年的工程运行结果表明，该组合工艺具有耐冲击负荷能力强、处理出水稳定达标、占地省等优点，对COD、BOD5、NH3-N、TN的平均去除率分别为99.8%、99.9%、99.0%、98.7%，渗滤液处理系统运行成本为47.05元/m3。
- Abstract:
- The leachate produced by the waste incineration power plant has the characteristics of complex pollutant composition, large fluctuations in water quality and quantity, high concentration of organic matter and ammonia nitrogen, difficult to treat. This paper takes a 450 m3/d leachate treatment project of the domestic waste incineration power plant as example. According to the characteristics of leachate from waste incineration power plants, UASB+A/O+MBR+two-stage RO combined treatment process was adopted to ensure that the effluent after treatment reached the Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889-2008). The amount of RO concentrate was treated by high-pressure space tube RO (STRO) reduction treatment and then re-injected incinerator. The engineering operation results in the past two years have shown that the combined process had the advantages of strong impact load resistance, qualification and stability of effluent, and space saving. The average removal rates of COD, BOD5, NH3-N, and TN were 99.8%, 99.9%, 99.0% and 98.7% respectively. The operating cost of the leachate treatment system was 47.05 yuan/m3.
