Dongguan water treatment equipment can promote the renewal of biofilm

           Water treatment equipment is helpful for biofilm inoculation to promote biofilm renewal, and the sedimentation effect of the primary sedimentation tank will be improved, but the returned biofilm is easy to block the filter material. The process returns the effluent from the biological filter directly, and the biological sludge in the secondary sedimentation tank is returned to the primary sedimentation tank. Through the above process, the organic matter in the sewage in the oxidation tank is reduced, and the biofilm on the sewage is purified. The biofilm on the turntable also experiences film growth and thickening. In the process of aging and falling off, the feature of the process is that there is no secondary sedimentation tank, and the effluent from the filter tank contains biological sludge directly back to the primary sedimentation tank, which can improve the effect of the primary sedimentation tank, and the sewage treatment equipment also has the function of secondary sedimentation. The process is suitable for wastewater with high suspended solids and low dissolved organic matter concentration.
                                             
            Compared with the process, the process can avoid increasing the volume of the primary sedimentation tank, and the process can improve the effect of the primary sedimentation tank, but it increases the load of the primary sedimentation tank. The biofilm absorbs oxygen from the air to oxidize organic matter. The reflux measures of the treated water make the high-load biological filter have a variety of processes, which are several representative processes of the single-pool system.
