Based on field visits and literature research, the situations of several typical wastewater treatment plants (WWTPs) in the Rhine basin and the Yangtze basin were investigated, to compare the technology and concept of wastewater treatment in these two areas. Our results showed that WWTPs in the Rhine performed well in pollutant removal, and have shifted their focus to energy production and nutrient recovery; While in the Yangtze basin, most WWTPs still operate on the sole concept of pollution treatment. Though China's WWTPs attach importance to water reclamation, the related technologies are still under development. In years to come, the construction of New Concept WWTPs is expected by Chinese famous experts, to integrate sustainable wastewater treatment and energy/nutrient recovery. To better plan its future avenue in wastewater treatment, China is suggested to learn from the successful practice of energy production and nutrient recovery of WWTPs in the Rhine.
基于实地考察和文献研究，调查了莱茵河流域和长江流域几个典型污水处理厂（WWTP）的情况，以比较这两个地区的污水处理技术和理念。研究结果表明，莱茵河流域的 WWTP 在去除污染物方面表现良好，已将重点转移到能源生产和营养物质回收上；而在长江流域，大多数 WWTP 仍仅基于污染治理的理念运行。尽管中国的 WWTP 重视水的再利用，但相关技术仍在开发中。未来，中国著名专家预计将建设新概念 WWTP，将可持续污水处理和能源/营养物质回收相结合。为了更好地规划未来的污水处理途径，中国建议借鉴莱茵河流域 WWTP 在能源生产和营养物质回收方面的成功实践。
