摘要：
Solar powered electrocoagulation technology is a new water treatment technology, which combines the renewable and sustainable characteristics of solar photovoltaic power generation and the advantages of electrocoagulation in wastewater treatment. Such as no need to add chemicals, less sludge production, easy operation of equipment and small land occupation. SPEC brings a more efficient, environmentally friendly and energy-saving water treatment method for areas rich in solar energy. The principle of electrocoagulation is expounded, and analyze the effects of anode material, electrode arrangement, current density, pH, initial conductivity and plate spacing on pollutant removal efficiency. Then the research progress of domestic and foreign scholars on the treatment of dye wastewater, phosphorus-containing wastewater, oily wastewater, diecentralized wastewater in remote areas and SPEC coupled with other technologies for wastewater treatment are emphatically discussed. In the end, the shortages and challenges of solar powered electrocoagulation technology are pointed out, and put forward prospect of the future research direction. © 2021, Chemical Industry Press Co., Ltd..
