Problems solved by technology

The disadvantage is that the amount of biological flocs in the water after the biological treatment of the soft packing layer increases, and the concentration of suspended solids in the mixed liquid is high. Without solid-liquid separation, it directly enters the hard packing layer, which is easy to cause the hard packing layer to harden.

Abstract

The invention relates to a composite biological carbon filtering device, and belongs to a water treatment device. The device comprises a shell (1), wherein a water storage tank (2) is arranged above an inner cavity (1a) of the shell; an outlet (3) is formed on the upper part of the water storage tank; a water outlet on the lower part of the shell is connected with a water outlet pipe (4); the water outlet pipe (4) is communicated with a water inlet (6) on the lower part of the water storage tank (2) through a water pipe (5); a water distribution pipe (8) connected with a water inlet pipe (7) is arranged on the upper part of the inner cavity (1a) of the shell; a biological activated carbon filtering layer (9), a supporting layer (10) and a secondary filtering layer (11) are arranged below the water distribution pipe (8) from top to bottom in turn; a perforated water distribution pipe (13) connected with an air inlet pipe (12) is arranged in the supporting layer (10); an air pipe (14) communicated with the inner cavity (1a) of the shell is arranged on the upper part of the shell; and the water inlet pipe (7) is connected with a backwashing water discharge pipe (15). The device can improve effluent quality, has a reasonable structure, can realize automatic backwashing by using the filtered water, and is easy and convenient to operate.

Description

technical field [0001] The invention relates to an advanced treatment device in the process of water treatment and purification. Background technique [0002] The combination of biological activated carbon with ozone or oxygen can effectively treat pollutants in water. Notification number CN2873759Y document discloses a "composite biological filter", its structure includes a shell, a water distributor connected to the water inlet pipe on the top of the inner cavity of the shell, and a soft packing layer, Hard packing layer, microporous aerator at the bottom of the soft packing layer, perforated aerator at the bottom of the hard packing layer, backwash outlet pipe on the top of the shell, outlet pipe connected to the bottom of the shell, and backwash inlet pipe connected to the outlet pipe , The "composite biological filter" uses biochemical effects such as biological oxidation and biological flocculation, and physical and chemical effects such as micro-flocculation, adsorpt...
