Width lifts the clean-up effect of water body, simultaneously because degradation biological on the biological filter bed of material, can further lift effluent quality；
(6) biologic packing material layer is due to the souring of vortex so that biologic packing material layer is not easy to block, and greatly reduces life
The backwash process of thing packing layer；
(7) biologic packing material layer is due to the effect of vortex so that the oxygen content increase in water body, this has greatly reinforced biology and filled out
The degradation of biomembrane on the bed of material, the water body purification effect further lifted；
(8) there is backwashing system in the technique, and this can greatly promote the service life of biologic packing material layer, because backwash is
One uniform scour process, the biomembrane that can maximally retain on biologic packing material layer is washed away during filler, while wash away
The sludge come passes through eddy-current system so that the sewage washed away is further purified, last sludgd deposition to device bottom, is led to
Cross draw clearly or other manner discharge.
(9) due to the addition of magnetic separation and recovery so that the system has good benefits of environment and economy.
