Embodiment 1

[0044] Example 1 Application of a bacterial agent containing Pseudomonas monsonii in purifying waste gas containing organic chlorine

[0045] A bacterial agent prepared by Pseudomonas monteilii (Pseudomonas monteilii) LW-1, which can be used to purify organic chlorine-containing waste gas and solve the pollution problem of volatile organic phosphorus produced in processes such as pesticide wastewater treatment, said The preparation method of bacterial agent is as follows:

[0046] (1) Fermentation broth preparation method

[0047] Pseudomonas monsonii LW-1 was cultured on a slant and then inserted into the fermentation medium, and the inoculation amount was 10% to expand the culture step by step. The fermentation conditions: 35°C, ventilation rate 10L / min, dissolved oxygen > 2.0mg / L, Under the condition of tank pressure 0.03-0.10Mpa, the cultivation time is 55h;

[0048] The composition of the slant medium is: glucose 0.5g, K 2 HPO 4 0.5g, KH 2 PO 4 1.5g, (NH 4 ) 2 S...

Abstract

The invention belongs to the field of environmental treatment, and in particular relates to the application of a bacterial agent containing Pseudomonas monsonii in purifying chlorine-containing waste gas. The Pseudomonas monteilii is specifically Pseudomonas monteilii (Pseudomonas monteilii) LW-1, the preservation number is CGMCC No.13748, and the bacterial agent is used to treat the organic chlorine-containing waste gas produced by the pesticide wastewater storage tank, Gas flow rate is 100‑5000m 3 / h, residence time 1.0-5.0min, temperature 35-55°C, chloral concentration 5-100mg / m 3 , the degradation efficiency of chloral can reach more than 75%.

Description

Technical field: [0001] The invention belongs to the field of environmental treatment, and in particular relates to the application of a bacterial agent containing Pseudomonas monteilii LW-1 in purifying volatile organic chlorine waste gas. Background technique: [0002] Wastewater from pesticide production contains a large amount of organosulfur pesticides and organochlorine pesticide intermediates, with complex components, high concentrations, and strong toxicity. Some organosulfur pesticides and organochlorine pesticide products or their intermediates, such as parathion, malathion, methyl parathion, chloral, phosphorus trichloride, etc., are volatile, and most of them are organic Sulfur and organochlorine pesticides have a pungent odor. [0003] Parathion (C 10 h 14 NO 5 PS) is a colorless oily liquid with a solubility in water of 24mg / L (25°C). Slightly soluble in petroleum ether and kerosene, miscible with most organic solvents, has garlic odor. Rapidly hydrolyzed...
