Biochemical equipment and treatment method for integrated treatment of waste gas and sewage

Abstract

The invention discloses a biochemical device for integrally treating exhaust gas and sewage. The biochemical device comprises a reactor tower body, an exhaust gas outlet, an exhaust gas inlet, a spraying device, a circulation liquid inlet, a manhole, structured enzymes floating filler, a settling zone, a circulation liquid outlet, a circulation water pump, a sewage inlet, a water collection zone, a water outlet and a valve. The filler is structured, the upper layer and the lower layer are arranged and installed in a crossed mode, liquid is secondarily and uniformly distributed in the downstream process, and due to the fact that the novel enzyme floating filler is very good in a hydrophilia and adsorbs zoogloea in muddy water very easily, sludge grows easily; due to the fact that intervals among the structured filler are uniform, no large difference exists between gas resistance and liquid resistance, and when reaching a certain thickness, a filler biological film can naturally disengage, and a dynamic balance is reached; the filler blockage problem is eliminated.

Description

technical field [0001] The invention relates to the technical field of environmental protection biological treatment, in particular to a biochemical equipment for integrated treatment of waste gas and sewage and a treatment method thereof. Background technique [0002] Including garbage treatment plants, feces treatment stations, fine chemical production plants, sewage sludge treatment plants, petrochemical, paint plants and other enterprises that produce low concentrations of malodorous gases or low concentrations of volatile organic compounds. There are many treatment methods for odor, which are mainly divided into ion method, combustion method and absorption and adsorption method, among which the most economical and effective method is biological method. There are three main processes for biological treatment of waste gas: biological scrubbing, biological filtration and biological trickling, among which biological trickling is the most commonly used biological deodorizati...

AI Technical Summary

Problems solved by technology

[0003] Commonly used biological trickling filter equipment can only be used for odor and simple organic waste gas treatment, but not for small flow sewage treatment in towns, villages, urban residential areas, medical institutions, small and medium-sized enterprises, and urban service industries

Conventional sewage treatment cannot be used for the treatment of odor and organic waste gas

[0004] In addition, conventional biochemical equipment uses ceramic Raschig rings, plastic Raschig rings and other fillers as fillers, which have the following defects: 1. The fillers are piled up in disorder, the surface is relatively smooth, and the filler itself does not absorb water, so there are slow biofilms and hangs. The problem of small film volume; 2. Due to the uneven accumulation and inconsistent channels, some channels will gradually become smaller during the operation of the device due to reasons such as hydraulic operation and coagulation of biological bacterial gelatinous groups, resulting in gas-liquid short flow and blockage. The treatment capacity and water effluent effect are greatly reduced, and the short-term water cut-off makes the packing layer easy to dry and harden
