NOVELTY - Tower-type biological filter pool comprises a tower pool body (1) and a tower pool cover (3). The tower pool body upper part is set with a sewage water inlet pipe (2). The tower pool body lower part is set with an air inlet system and a drainage system. The drainage system comprises a water collecting tank (10), a clean water outlet water pipe (11) and a sewage circulation pipe. A tower filtering pool lower end is set in water collecting tank. The system comprises an air inlet gap set with an air inlet set on tower body wall pool. A rotating cloth device is set with sewage water inlet pipe.    USE - Used as a tower-type biological filter pool.    ADVANTAGE - The filter pool rapidly forms breeding bed exhibiting good bio-oxidation treatment performance of industrial waste water, can degrade refractory organic pollutants with high stability, provides natural ventilation during oxidation, is economical, and produces water with good quality.    DETAILED DESCRIPTION - Tower-type biological filter pool comprises a tower pool body (1) and a tower pool cover (3). The tower pool body upper part is set with a sewage water inlet pipe (2). The tower pool body lower part is set with an air inlet system and a drainage system. The drainage system comprises a water collecting tank (10), a clean water outlet water pipe (11) and a sewage circulation pipe. A tower filtering pool lower end is set inside water collecting tank. The system comprises an air inlet gap which is set with an air inlet located on the tower body wall pool. A rotating cloth device is provided with sewage water inlet pipe. The tower pool body lower part is set with a filtering material body whose lower part is set on a water distributor. The filter material body is set with filter body many layers of foaming cement concrete brick intertwined with spacer masonry. The foam cement concrete brick is located between honeycomb-shaped ventilating channels. The foaming cement concrete brick comprises microbial cultures agent and an oxidation catalyst.
