Waste water cryogenic treating apparatus for deaminizating phosphor-removing ventilating layer

A waste water treatment equipment with the aerate layer of ammonia and phosphorus removal. The hollow material layer which have the function of ammonia and phosphrus removal divided the percolation fileration layer into aerobic layer and anaerobic layer. The waste water flow through the anaerobic layer from up to down to remove the SS, BOD, NH4+-N, T-P. The invention can remove the NH4+ and P efficiently and deal with the wastewater deeply.
