    • A water treatment apparatus includes a plurality of meshed tubes made of synthetic yarn and provided with cilia; a plurality of tube stack cages containing the meshed tubes; and an aeration diffuser positioned between the tube stack cages and configured to provide air so that to-be-treated influent water moves to the tube stack cages. The hollow interior of the filter media, i.e. meshed tubes, enables water to move in any direction, and the high porosity maximizes the area for filtering of suspended solids and attachment of microorganisms. The resulting efficiency of removal of suspended solids and soluble organic material is far greater than conventional methods. Arrangement of diffusers in the middle of the reaction tank and between the tube stack cages and aeration by them result in perfect mixing in the reaction tank. The load of suspended solids and soluble organic materials is evenly distributed over the entire filer media.
    • 水处理装置包括由合成纱线制成并具有纤维的多个网眼管; 包含所述网状管的多个管堆笼; 以及曝气扩散器,其位于所述管堆叠笼之间并且构造成提供空气,使得待处理的流入水移动到所述管堆笼笼。 过滤介质的中空内部,即网状管,使得水能够在任何方向移动,并且高孔隙率使用于过滤悬浮固体和附着微生物的面积最大化。 所得到的悬浮固体和可溶性有机材料的去除效率远远大于常规方法。 在反应槽中间和管堆笼之间以及它们通气之间的扩散器的布置导致反应罐中的完美混合。 悬浮固体和可溶性有机材料的负载均匀分布在整个过滤介质上。
