摘　　要：探索光电联合反应的可行性,通过对阴极(Ti)涂覆光催化剂薄膜前后进行对比试验,发现涂膜后阴极在电化学反应中表现出相对较强的氨氮去除效果,以此为基础开展基于阳极直接氧化及阴极吸附光催化氧化模式的光电联合反应装置设计。在相同通电功率和光照条件下,与单纯光催化氧化和单纯电化学氧化法相比,光电联合反应表现出相对更高的氨氮去除效率。This study explores the feasibility of the photoelectric joint reaction.Through comparison tests before and after the cathode(Ti)was coated with a photocatalyst film,it was found that the coated cathode exhibited a relatively strong ammonia-nitrogen removal effect in the electrochemical reaction.The design of a photoelectric joint reaction device based on direct anode oxidation and cathode adsorption photocatalytic oxidation modes was carried out.Compared with the pure photocatalytic oxidation and pure electrochemical oxidation methods,under the same energizing power and light conditions,the photoelectric joint reaction shows a relatively higher ammonia-nitrogen removal efficiency.
