摘要:
青岛李村河污水处理厂采用移动床生物膜反应器（MBBR）工艺进行升级改造，利用悬浮载体生物膜高效的处理性能以及MBBR工艺“镶嵌”式改造方式，实现了生化段原位扩容提标，出水标准由《城镇污水处理厂污染物排放标准》（GB 18918—2002）的二级标准提升至《地表水环境质量标准》（GB 3838—2002）的准Ⅳ类标准，处理水量由17.0万m3/d提升至25.0万m3/d。MBBR工艺运行10年来，显示出良好的抗低温、抗水质水量冲击能力，出水氨氮、TN分别达到（0.44±0.28）、（7.75±2.60） mg/L。MBBR高效稳定的核心在于生物膜对硝化细菌的富集能力较强，其相对丰度可达23%，是活性污泥的15倍。重点介绍了MBBR工艺专用设备材料（悬浮载体、拦网、搅拌器等）的运行维护，指出了运行过程中存在的问题及改进措施。分析了“循环流动”和“微动力混合”两种流化池型的优缺点。MBBR工艺运维控制的核心是悬浮载体流化，需要可靠的设计和设备支撑。
Abstract:
The Qingdao Licunhe wastewater treatment plant has been continuously upgraded by MBBR process. By using the highly efficient treatment performance of suspended carrier biofilm and the embedded retrofitting mode of MBBR process, the biochemical section has been expanded in-situ to improve the quality and quantity. The effluent standards were raised from grade Ⅱ of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to quasi-Ⅳ standard of Environmental Quality Standards for Surface Water (GB 3838-2002) , and the treated water volume was increased from 170 000 m3/d to 250 000 m3/d. Over ten years of operation, the MBBR process has demonstrated excellent resistance to low temperatures and shocks from variations in water quality and quantity. The effluent ammonia nitrogen and TN levels reached (0.44 ± 0.28) mg/L and (7.75 ± 2.60) mg/L, respectively. The core of MBBR’s high efficiency and stability lies in the strong enrichment ability of biofilm to nitrifying bacteria, with its relative abundance up to 23%, 15 times that of activated sludge. This paper also analyzes the special equipment for MBBR, such as suspended carrier, screen and mixers, and points out the problems existing in the equipment during the process operation and the corrective measures. The advantages and disadvantages of “circulating flow” and “micro-power mixing” fluidization tank type are summarized. The core of operation and maintenance control of MBBR process is to control the fluidization of suspended carrier, which requires reliable design and equipment support.
