Problems solved by technology

However, this kind of odor treatment method also has the following disadvantages: firstly, the microorganisms used in this type of biological filtration device have not been specially screened and domesticated, and the deodorizing effect is not satisfactory; secondly, the formula of the nutrient solution is only It is set according to the growth needs of microorganisms, without considering that odorous substances can also be used by microorganisms as nutrients, so that the nutrient solution will become eutrophic due to the excessive growth of microorganisms, and the nutrient solution needs to be regularly updated
This not only increases operating costs, but also needs to be treated in order to eliminate the environmental pollution of the eutrophic nutrient solution that is replaced; third, this type of biological filter device does not provide the required nutrients for the various microorganisms that participate in the removal of odorous substances. special ecological environment
This not only cannot give full play to the deodorizing ability of microorganisms, but also aggravates the eutrophication of the nutrient solution.

example 1

[0018] The biological deodorization treatment device is made of PVC board into a box. The residence time of the malodorous gas in the box is 30 seconds; the flow velocity of the malodorous gas in the box is 0.5 m / s; the total airflow resistance of the box is equal to the wind pressure of the exhaust fan that presses the malodorous gas. The box body is divided into four parts connected vertically and vertically by staggered vertical partition boards (2). The bottom is a liquid storage tank (3) equipped with microbial nutrient solution, and a liquid level controller (4) is provided to replenish evaporated water in time. The LQ-SSB complex microbial flora is placed in the nutrient solution. A porous shelf (5) is installed at a certain height from the bottom of the box body, and porous plastic balls (9) with a certain height of nanocomposite mineral carriers are stacked on the upper part; ammonia, hydrogen sulfide, mercapto compounds, amine compounds , lower fatty acids and alde...

example 2

[0021]The biological deodorization treatment device is made of stainless steel plate into a box. The residence time of the malodorous gas in the box is 25 seconds; the flow velocity of the malodorous gas in the box is 0.8 m / s; the total air flow resistance of the box is less than the wind pressure of the exhaust fan that presses the malodorous gas. The exhaust fan adopts the form of horizontal air outlet to reduce the wind resistance of the pipeline. The box body is divided into five parts connected up and down by vertical partition boards (2) staggered up and down, so as to increase the residence time of malodorous gas in the deodorizing biological deodorization device. The bottom is a liquid storage tank (3) equipped with microbial nutrient solution, and a liquid level controller (4) is provided to replenish evaporated water in time. The LQ-SSB complex microbial flora is placed in the nutrient solution. A porous shelf (5) is installed at a certain height from the bottom of...

Abstract

The invention relates to a method for using composite microbe and nanometer composite carrier to treat the gas with bad smell, and relative device. The box of biological filter is divided by several upright baffle plates, which contains microbe nourishment storage pool, a liquid level controller, a porous baffle plate, a nourishment spray tube, and a nourishment circulate pump, while the bad smell flows in the box to contact with the nanometer composite mineral carrier stacked on the porous baffle plate, to degrade the object via the microbe group on / in the nanometer composite mineral carrier into the material without toxicity and harm, as water, carbon dioxide, nitrogen gas and sulfur. And the invention uses the bad smell object as the carbon source, energy source, nitrogen source and sulfur source of microbe to realize circulation, save cost and reduce nourishment consumption. The invention has simple structure and low cost, while the LQ-SSB composite microbe group and nanometer composite mineral carrier have high stability and efficiency.

Description

Technical field: [0001] The invention belongs to the technical field of removing malodorous gas produced by municipal solid waste and residential septic tank sludge, and in particular relates to a method and device for biological deodorization treatment. It can be applied to remove the malodorous gas produced during the treatment of municipal solid waste and municipal fecal sludge. Background technique: [0002] With the enhancement of people's awareness of environmental protection and the improvement of environmental quality requirements, they are more sensitive to the pollution of malodorous gases. Smelly substances can not only make people feel unpleasant and disgusting, but also many of them are harmful to people's health and even life, especially ammonia, hydrogen sulfide, methyl mercaptan, low-grade Odor gas substances such as fatty acids and amines have become serious environmental pollutants. Therefore, when municipal solid waste and municipal fecal sludge are tran...
