环境友好型城市污水处理厂

城市污水处理厂对解决我国日益严重的水污染问题起到了重要作用,不过城市污水处理厂出水达不到地表水标准,产生剩余污泥,释放恶臭气体、温室气体和气溶胶等,以上都会对环境造成影响,而且污水处理厂运行时需要外界提供大量能量。本研究针对以上问题,基于清洁生产和循环经济的理念,提出了"环境友好型城市污水处理厂"的理念。该污水厂将污水处理单元、污泥处理和产电单元、恶臭气体、气溶胶和温室气体处理单元以及太阳能发电单元等有机融合,单元与单元之间互相促进,能基本实现污染零排放,且能源需求量大大降低。

Environment-friendly Urban Sewage Treatment Plant

Urban sewage treatment plant play an important role in solving the increasingly serious water pollution problems in our country. But the effluent quality of the city sewage treatment plant can＇t reach surface water standards as well as to produce residual sludge, to release malodorous gases, greenhouse gases and aerosols, all of this problems have an adverse effect on environment. What＇s more, the sewage treatment plant running in the condition of provided a lot of energy In this study, to solve the above problems, the idea of ＇environment-friendly urban sewage treatment plant＇ that based on clean production and circular economy concept has been present. The wastewater treatment plant will promote organic integration between organic wastewater treatment unit, sludge treatment and electricity generation units, malodorous gases, aerosols and greenhouse gas treatment unit and a solar power unit, etc. Unit and unit promote mutually to achieve the goals of zero pollution release and greatly reduce energy demand.
