Soil composite biological deodorization equipment

Abstract

The invention discloses soil composite biological deodorization equipment which comprises a concrete pond bottom, an odor pipeline and turf, the odor pipeline is arranged above the concrete pond bottom, a gas distribution layer is arranged at the lower end of the odor pipeline, and a glass fiber reinforced plastic grating is arranged above the gas distribution layer and fixed to the edge side of the concrete pond bottom. A volcanic rock filler layer is arranged above the glass fiber reinforced plastic grating, and a deodorization layer is arranged above the volcanic rock filler layer. According to the soil composite biological deodorization equipment, 30% of volcanic rocks are added into soil, components of single soil are improved and are changed into composite components, the soil composite biological deodorization equipment is resistant to hardening, easy in strain biofilm culturing and high in air permeability, 50 cm volcanic rocks are padded under the soil, biofilm culturing can be carried out for strain culturing, meanwhile, the stink retention time can be prolonged, stink can more uniformly pass through the equipment by the bottom built on stilts. Meanwhile, a heating circulating pipeline can be arranged in the soil layer according to needs, and it is guaranteed that strains can have the proper survival temperature in cold winter.

Description

technical field [0001] The invention relates to the technical field of biological deodorization, in particular to soil composite biological deodorization equipment. Background technique [0002] With the increase of people's awareness of environmental protection, the requirements for the environment are getting higher and higher. When the malodorous gas is discharged, it will be treated by a deodorization device. The existing malodorous gas treatment methods mainly include physical methods and chemical methods. There are three types of biological methods, the common gas deodorization method in the biological method, the principle is to directly cultivate deodorizing bacteria in the soil, so that the odor passes through the soil, and the odor is decomposed by the microorganisms in the soil to achieve deodorization effect, but this kind of deodorization equipment also has some shortcomings when used: [0003] The existing deodorization equipment uses a single soil layer to pr...

Problems solved by technology

[0005] The purpose of the present invention is to provide a kind of soil composite biological deodorization equipment, to solve the problem that the existing deodorization equipment on the market proposed by the above background technology uses a single soil layer to process the gas, and the single soil is easy to harden when it meets water, and the biofilm It is difficult to survive, and the single soil has poor air permeability, high resistance, insufficient height of soil filling layer, and short residence time of odor
