摘  要:光催化耦合微生物降解技术,在微生物代谢后期,污水中COD下降到光催化剂反应的范围,利用光能激发催化反应,将有机物质氧化成活性基团,可以将水体中难降解的有机物分解。以碳棒作为阳极,以碳布材料作为阴极,以负载TiO_(2)的活性炭作为生物载体,构建微生物燃料电池体系。葡萄酒废水酸性环境下微生物的生长缓慢,当阳极底物质量浓度由1000 mg·L^(-1)增大到3000 mg·L^(-1)时,COD去除率由较低水平的67%增大到较高水平的92%。在一定范围内,随着阳极底物质量浓度的增加,COD的去除率也有所增加。当阳极底物质量浓度由3000 mg·L^(-1)增大到4500 m·L^(-1)时,COD去除率由92%减小到81%,光催化的引入对处理低浓度的氨氮、总磷和COD效果均高于90%。During using photocatalytic coupling microbial degradation technology,in the late stage of microbial metabolism,COD in sewage is reduced to the range of photocatalytic reaction,and light energy is used to stimulate catalytic reaction to oxidize organic substances into active groups,which can decompose refractory organic substances in water.A microbial fuel cell system was constructed by using carbon rods as anodes,carbon cloth materials as cathodes,and activated carbon loaded with TiO_(2) as biological carriers.The growth of microorganisms in the acidic environment of wine wastewater was slow.When the mass concentration of anode substrate increased from1 000 mg·L^(-1) to 3 000 mg·L^(-1),the COD removal rate increased from 67%to 92%.The mass concentration of anode substrate increased to a certain extent,and the removal rate of COD in the anode chamber of MFC increased accordingly.When the anode substrate mass concentration was increased from 3 000 mg·L^(-1) to 4 500 m·L^(-1),the COD removal rate decreased from 92%to 81%.The removal rates of ammonia nitrogen,total phosphorus and COD under low concentrations were more than 90%after the introduction of photocatalysis.
