Abstract

The invention belongs to the field of environmental protection, and in particular relates to a microbial active filler containing Brachybacterium nesterenkovii. The Brachybacterium nesterenkovii is specifically (Brachybacterium nesterenkovii) NY-1, and the preservation number is CGMCC No. 13747. The microbial active filler containing the Brachybacterium nesterenkovii NY-1 is higher in degradationefficiency of organochlorine, and the degradation efficiency of the organochlorine can reach 90 to 96%; moreover, the adaptation period of dominant bacteria is short, and the degradation reaction canbe quickly started within one week, and the bioactive filler is applied to a bioreactor for purifying organochlorine-containing waste gas, so that the starting period can be shortened.

Description

Technical field: [0001] The invention belongs to the field of environmental management, and in particular relates to a biologically active filler of Brachybacterium nesterenkovii NY-1. Background technique: [0002] Organochlorine pesticides are organic compounds containing organochlorine elements in the components used to prevent and control plant diseases and insect pests, and are recognized as a very important class of persistent organic pollutants. During the production of organochlorine pesticides and the treatment of pesticide wastewater, volatile pesticide products or intermediates volatilize from the liquid phase and escape into the air, forming air pollution. Volatile pesticides and intermediates include: trichlorfon, dichlorvos, phosphorus trichloride, DDT, chloral urea, sodium trichloroacetate, HHC, aldrin, chlordane, endrin, seven Chlorine, toxaphene, hexachlorobenzene, mirex, chloral, etc. Most of these substances have a pungent smell, and some substances, such...
