摘　　要：某采用百乐克(Biolak)工艺的城镇污水处理厂,为符合准Ⅳ类高标准尾水的深度治理需求,通过系统梳理原有设施工艺短板及指标达标弱项,采取了提升上游污水内碳源纳管效能、实施污水厂的泥水提标等厂网协同提质增效措施。采用改良Bardenpho作为主体新处理工艺,进行了将传统五段Bardenpho的厌氧区与缺氧区空间倒置,进水多点分布,增设消氧脱气区等利于硝化、脱氮、降碳、除磷的改良设计。引进节能变频风机、新型高效免停水曝气器、低氧曝气的节能运行策略,辅以集约占地的加砂澄清池。实际出水指标浓度稳定在新排放限值的65%以下,污泥减量48%,单位电耗、药耗分别节约16%、28%,再生水回用率超过30%。In order to meet the enhanced treatment requirements of level quasi-Ⅳ discharge standard, an urban wastewater treatment plant with Biolak tank as its main process, takes coordinal measures of WWTP and drainage network for quality and efficiency improvement, such as improving the efficiency of inner carbon source from upstream sewage into the influent and implementing the sludge sewage upgrading, through systematically sorting out the shortcomings of the original facilities and indicators to reach the standard. The modified Bardenpho process was adopted as the new treatment unit of the WWTP, namely, the anaerobic zone and anoxic zone of the traditional five-stage Bardenpho was spatially inverted, with multipoint distribution of influent, the addition of deaeration zone and other benefit to improve nitrification, denitrification, carbon reduction and phosphorus removal was designed. It introduces energy-saving frequency variable blower, new efficient aerator without water cut-off for maintenance, as well as operation strategy of low oxygen aeration to save energy, and is also supplemented by sand adding clarifier with intensive footprint. Thus the actual effluent pollutant concentration is stably below 65% of the new discharge limits and the sludge is reduced by 48%. The energy and chemical consumptions are saved by 16% and 28% respectively. The recycle rate of reclaimed water exceeds 30%.
