Embodiment 1

[0020] Citrate pylorgi ZT-S5 was cultured by culture fluid, and the concentration of CFU values ​​of 1.1 × 109 were obtained by 1.1 × 109 concentration CFU value of 1.1 × 109;

[0021] Pour the Citrogen pylori ZT-S5 bacterial solution into a self-made reactor of 1 cubic meter;

[0022] Pour 400L diameter of 3-5 mm wood base carbonized wood;

[0023] Open the bottom of the reactor, ventilation for 2 hours, stop the intake air standing for 2 hours, the ventilation is 2 hours, stop the intake of allowing for 2 hours, pull out the pull-free screen box, naturally drained water, the wood-based granules Carbon carrier solidification microbial filler about 400L;

[0024] Pour the 400L wood-based granulated carbon carrier into 1 cubic meter diameter 1-3mm, about 30% of the porosity, and the specific surface area of ​​8 m2 / g, the mixture is stirred, One biological soil deodorization is composite filter material.

Embodiment 2

[0026] The three diameter of 20 cm, a height of 100 cm is produced, and a biological soil deodorizing composite filter material (filter column A), volcanic filter (filter column B), a volcanic filter material (filter column B), and volcanic filtration filter (filter column B). Bamboo charcoal filter material (filter column C).

Abstract

The invention provides a composite filter material for biological soil deodorization and application thereof. The composite filter material is mainly composed of semi-weathered sandy soil filter material and wood-based granular carbon carrier solidified microbial filler. The semi-weathered sandy soil filter material has a diameter of 1-3mm, a porosity of 20%-40%, and a specific surface area of ​​6-10m2 / g. Wood-based granular carbon carrier solidified microbial filler carrier is carbonized broken wood particles, the particle diameter is 3-5mm, the carbonization condition is 600°C-700°C anoxic condition, and the carbonization time is 3-5h. The microorganism used in the wood-based granular carbon carrier solidified microbial filler is a kind of Facultative Citrobacter ZT‑S5 (Citrobacter sp.), and the strain preservation number is CGMCC No.15120. Maintain the abundance and activity of microorganisms, and quickly restart after a long period of shutdown, so that the biological soil deodorization system can quickly meet the waste gas treatment requirements. The invention is easy to obtain materials, and the wood-based granular carbon carrier solidifies the microbial filler to make a simple process, and the source of the Citrobacter used is collected from a sewage treatment plant, without secondary pollution and ecological risk.

Description

Technical field [0001] The present invention relates to the field of malodous exhaust gas treatment, and more particularly to composite filter materials for biological soil deodorization. Background technique [0002] The sewage industry produces a large amount of exhaust gas containing malodoric components such as hydrogen sulfide, ammonia, organic sulfur, organic amine during sewage collection, delivery and treatment. The malodous exhaust gas needs to be treated to meet environmental requirements, reducing the health hazards of staff and surrounding residents. The existing malodous exhaust treatment technology mainly includes biological deodorization, chemical washing deodorization, adsorption deodorizing, photoelectric plasma deodorizing, plant fluid spray odor, etc. Among them, biological deodorization is widely adopted in the sewage industry due to its stable treatment effect, simple operation, low operation and maintenance costs, high environmentally friendly.
