摘 要:某市政生活污水处理厂拟进行提标扩能改造,处理规模由现状5万m^(3)/d扩建至10万m^(3)/d,出水标准由现状一级B标准提升至“地表准Ⅳ类水”标准。为探索节能经济的改造方案,案例针对提标扩能改造中的传统解决方案和新型精细膜法解决方案进行对比分析,结论得出:新型精细膜法解决方案较传统方案施工周期短、施工难度小,在用地紧张的改造项目中有较大优势;新型精细膜法方案在工程总投资节约32.3%的同时,每吨水处理利润可提升30%。由此,新型精细膜法解决方案在国内污水厂提标扩能改造项目中的占比具备较大提升潜力,案例为今后国内污水厂改造工艺的选择提供新的思路。A municipal WWTP plans to upgrade the effluent standard and capacity.The treatment scale will be expanded from the current 50000 m/d to 100000 m/d,and the effluent standard will be upgraded from the first class B discharge standard to the quasi class IV criteria of surface water.In order to explore energy-saving and economic transformation plans,this case elaborates on the process design principles of traditional solutions and new fine membrane solutions,and compares the economic indicators of the two.By comparison,it can be concluded that the new fine membrane method solution has a shorter construction period and lower construction difficulty compared to traditional methods,and has significant advantages in land intensive renovation projects;Meanwhile,the new fine membrane method scheme can save 32.3%of the total project investment and increase the profit per ton of water treatment by 30%.Therefore,the proportion of new fine membrane solutions in domestic WWTP upgrading and capacity expansion projects has great potential for improvement.This case provides new ideas for the selection of WWTP renovation processes in the future.
