Problems solved by technology

[0003] At present, domestic rubber tire companies mostly use water absorption and activated carbon adsorption methods, but due to the treatment effect, operation management, operating costs and other reasons, the problem of odor pollution cannot be solved fundamentally. The biological method of odor gas treatment has the advantages of simple equipment, low investment and low operating costs. Low cost, convenient maintenance and management, good effect, etc. Biological method can be used to treat rubber waste gas

Embodiment 1

[0030] A microbial composite bacterial agent for degrading waste gas from a rubber factory, comprising, in parts by mass, 10 parts of Bacillus atrophaeus, 5 parts of Stenobacter brevis, 2 parts of Photobacterium luminescent, 2 parts of Pseudomonas alcaligenes, and Cladobacillus pantothenicis Bacillus 2 parts, Pseudomonas putida 10 parts.

[0031] Application of exhaust gas treatment in the mixing workshop of tire factory: inoculate the microbial compound bacterial agent into the biological box of the biological trickling filter tower, the inoculation amount is 10% of the circulating water quality in the water tank of the biological trickling filter tower, and the waste gas from the inlet of the biological trickling filter tower The waste gas is passed through, and the concentration of VOCs in the waste gas at the inlet is detected before treatment, and the concentration of VOCs in the waste gas at the outlet of the biological trickling filter is detected one week later. The te...

Embodiment 2

[0033] A microbial composite bacterial agent for degrading waste gas from a rubber factory, comprising, calculated in parts by mass, 5 parts of Bacillus atrophaeus, 5 parts of Stenobacter brevis, 5 parts of Photobacterium luminescent, 5 parts of Pseudomonas alcaligenes, and Cladobacillus pantothenicis Bacillus 5 parts, Pseudomonas putida 5 parts.

[0034] Application of exhaust gas treatment in the vulcanization workshop of rubber products factory: inoculate the microbial compound bacterial agent into the biological tank of the biological trickling filter tower, the inoculation amount is 5% of the circulating water quality in the biological trickling filter tower water tank, and the waste gas from the biological trickling filter tower exhaust gas inlet The waste gas is passed through, and the concentration of VOCs in the waste gas at the inlet is detected before treatment, and the concentration of VOCs in the waste gas at the outlet of the biological trickling filter is detecte...

Embodiment 3

[0051] The preparation method of the microbial composite bacterial agent, the specific preparation steps are as follows:

[0052] (1) Determination of the composition of waste gas from rubber factories

[0053] According to the gas sampling method of GB16157-1996 "Sampling Method for Particulate Pollutants and Gaseous Pollutants in Exhaust from Stationary Pollution Sources", waste gas from rubber factories is collected, and the recovered gas is analyzed by GC-MS. The analysis results show that the main components of waste gas from rubber factories are Toluene and xylene;

[0054] (2) Sampling and preparation of medium

[0055] Take the bottom sludge discharged from the rubber factory as the inoculum, settle the fresh bottom sludge for 30min, and take 50mL of thick bottom sludge with sterile water to make 10 -7 , 10 -8 , 10 -9Gradient dilution, for use, prepare the selective medium with toluene and xylene as carbon source;

[0056] The selective medium components are: tolu...

Abstract

The invention discloses a microbial compound fungicide for degrading waste gas of a rubber plant and a preparation method and application thereof. The compound fungicide comprises, by mass, 5-10 partsof bacillus atrophaeus, 5-10 parts of empedobacter brevis, 2-5 parts of photobacterium beijerinck, 2-5 parts of pseudomonas alcaligenes, 2-5 parts of virgibacillus pantothenticus and 5-10 parts of pseudomonas putida. The microbial compound fungicide can be applied to degradation of the waste gas of the rubber plant, the degradation effect is good, the culture cost is low, the microbial compound fungicide is easy and convenient to use, the VOCs removal rate is 90% or above, and the national emission standard is met.

Description

technical field [0001] The invention belongs to the technical field of waste gas treatment, and in particular relates to a microbial composite bacterial agent for degrading waste gas from a rubber factory, a preparation method and application thereof. Background technique [0002] In the production process of rubber tires, both the vulcanization and rubber mixing processes produce process exhaust gas. These odorous exhaust gases are harmful to the human body and cause serious disturbance to the people. In recent years, there have been more and more odor complaints against rubber tire companies, which has brought great harm to the normal life of rubber companies. Development has brought great influence, so the problem of odor pollution has become one of the environmental protection problems urgently to be solved by rubber tire enterprises [0003] At present, domestic rubber tire companies mostly use water absorption and activated carbon adsorption methods, but due to the tre...
