Novel photocatalytic reactor for degradation of DDT in water and its optimization model

一张新奇相片催化反应堆被开发搬迁(从水的 1,1 二度(4-chlorophenyl )-2,2,2-trichloroethane)(DDT ) 。在反应堆， cenosphere 被用来支持借助于大音阶的第五音胶化做的 TiO 2 电影。因为 cenospheres 与 TiO 2, 是涂的，他们的比重稍微从原版被增加 0.6 ∼0.8 到 0.8 ∼0.9，以便他们能在水里被推迟。与 bubbler 的混合操作，在反应堆的水处于一个使流体化得好的状态。反应堆的底部是一张沙过滤器床，它能被用来阻止光催化剂被失去。反应堆的一个数学模型在二个主要有影响的因素被开发了：紫外(紫外) 轻紧张和光催化剂集中。与如此的一个模型一起，反应堆能更相当被设计。

A novel photocatalytic reactor was developed to remove （1,1-bis（4-chlorophenyl）-2,2,2-trichloroethane） （DDT） from water. In the reactor, a cenosphere was used to support TiO2 film made by means of sol-gel. Because the cenospheres were coated with TiO2, their specific gravity was slightly increased from the original 0.6-0.8 to 0.8-0.9, so that they were able to be suspended in water. With the mixed operation of a bubbler, the water in the reactor was in a well-fluidized state. The bottom of the reactor is a sand filter bed, which can be used to prevent the photocatalyst from being lost. A mathematical model of the reactor has been developed in the two primary influential factors： ultraviolet （UV） light intensity and photocatalyst concentration. With such a model, the reactor can be designed more reasonably.
