利用太阳光与固定床型光反应器处理有机废水的研究

自制了一种模拟工业处理废水的光催化反应器。该反应器将TiO2固定在玻璃板上，以太阳光为光源，以邻氯苯酚为处理对象，研究了邻氯苯酚水溶液光降解的可行性。结果表明，在实验条件下，该系统能对邻氯苯酚水溶液进行有效的光解。光照60分钟后．其降解率可达87％。此外还探讨了流速、邻氯苯酚溶液初始浓度和初始pH值对光解反应的影响。

Fixed-bed reactor for water decontamination using solar light

A photocatalytic reactor using immobilized TiO2 on a glass plate was studied on a bench scale using solar light as the source of radiation,aqueous o-chlorophenol solution was selected as a model compound. It showed that o-chlorophenol was remarkably photolized under the condition of the experiment. The influence of parameters such as the slope of the plate, flow rate, as well as the initial concentration and pH of ochlorophenol solution was studied. An initial concentration of 1 mmol/L of o-chlorophenol decayed to 0. 13 mmol/L in about 60 min of irradiation.
