简介: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TiO2电影。因为cenospheres与TiO2,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。
