Municipal wastewater treatment plants (WWTPs) will face challenges in the coming decades including reducing energy consumption and decreasing carbon emissions. These challenges can be addressed by combining electrochemical, biological, and bio-electrochemical technologies within existing WWTPs. The results from this review indicate that electrochemical technology is an effective advanced treatment method for WWTPs. However, electrochemical technology is not yet economically suitable as a stand-alone unit for treating wastewater because it consumes energy in the operation process. Electricity generation from biological and bio-electrochemical technologies can provide the power supply needed for WWTP electrochemical processes while reducing greenhouse gas emissions. WWTPs coupled with electrochemical, biological, and bio-electrochemical technologies can increase electricity recovery in WWTPs, impart energy self-sufficiency to the WWTPs, and decrease greenhouse gas emissions.
未来几十年，城市污水处理厂（WWTP）将面临减少能源消耗和降低碳排放的挑战。这些挑战可以通过在现有的 WWTP 中结合电化学、生物和生物电化学技术来解决。本综述的结果表明，电化学技术是 WWTP 的一种有效高级处理方法。然而，电化学技术在作为处理废水的独立单元方面还不具有经济性，因为它在运行过程中消耗能源。生物和生物电化学技术产生的电能可以为 WWTP 的电化学过程提供所需的电力供应，同时减少温室气体排放。与电化学、生物和生物电化学技术相结合的 WWTP 可以提高 WWTP 的电力回收，赋予 WWTP 能源自给自足的能力，并减少温室气体排放。
