摘要
太阳能电絮凝技术(SPEC)是一种水处理新技术,其结合了太阳能光伏发电可再生、可持续的特点和电絮凝处理废水无需添加化学药剂、产泥量少、设备易操作、占地小的优势,为太阳能丰富的地区带来了更加高效、环保和节能的水处理方法。本文阐明了电絮凝的原理,并分析了阳极材料、电极连接方式、电流密度、初始pH、电导率和极板间距对废水中污染物去除效率的影响。随后,重点综述了国内外学者对SPEC技术处理染料废水、含磷废水、含油废水、偏远地区分散式废水和SPEC与其他技术耦合处理废水的研究进展。最后,点明了SPEC技术当前存在的不足及挑战,并对未来的研究方向提出了展望。
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.
