采用颗粒污染物的旋流分离模型设计了螺旋升流塔式光催化反应器,能够在悬浮态光催化反应系统中提高光催化剂的回收率.反应器采用塔式结构布置,能有效提高反应器的光照面积与反应液体积之比(A/V值),在本试验条件下A/V值可达到12.95.采用该反应器处理硝基苯模拟废水,当硝基苯初始浓度为466 mg/L时,反应器对硝基苯的去除率稳定在60%左右,运行12 h后对光催化剂的回收率为92.80%.

Based on the cyclone separator model for granular pollutants, a spiral up-flow tower-type photocatalysis reactor was designed to increase the recovery rate of photocatalyst. In order to reach a high A/V ratio (the ratio of illumination area to reaction solution volume), a tower structure was used on this reactor, and the A/V ratio can reach 12.95 in this experimental condition. This reactor was used to treat the nitrobenzene simulated wastewater. When the initial concentration of nitrobenzene is 466 mg/L, the removal rate of nitrobenzene is about 60%, and the photocatalyst recovery rate reaches 92.80% after 12h.
