Biological adsorption tower for reclaimed water reusing system

A biological adsorption tower for reclaimed water reusing system which belongs to the waste water or sewage processing field includes a vertical tower, characterized in that at least a netlike grid is disposed between the water inlet and water outlet of the tower; a stuffing layer is formed by filling biological stuffing between two netlike grids, the surface of the biological stuffing which is crop straw is covered by active biomembrane. The utility model is capable of satisfying the need for microbe biochemical processing technique with small occupying space, simple structure, low running costs, without secondary pollution, reclaiming resources for usage, is widely used for the water purification technical field of constructed wetland system.
