Abstract

The invention discloses a bacterial agent for production of diacetone alcohol degradation bacteria during sewage treatment and a preparation method of the bacterial agent. The bacterial agent comprises the diacetone alcohol degradation bacteria, yeast, glucose, sodium chloride, sodium metasilicate pentahydrate, fatty alcohol polyoxyethylene ether and the balance active water. The preparation method comprises the following steps of S1, material preparation; S2, culture of a primary-generation diacetone alcohol degradation bacterium colony; S3, culture of a multi-generation diacetone alcohol degradation bacterium colony; S4, concentrated culture of the diacetone alcohol degradation bacterium colony; S5, preparation of the bacterial agent with the diacetone alcohol degradation bacterium colony. According to the bacterial agent, the adopted composition is an international regulation raw material, and the produced bacterium colony of the prepared bacterial agent with the diacetone alcohol degradation bacterium colony has high concentration, high activity and a good degradation effect, has advanced significance on treatment of water pollution and has high commercial popularization value.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a bacterial agent for production of diacetone alcohol-degrading bacteria in sewage treatment and a preparation method thereof. Background technique [0002] Diacetone alcohol is an intermediate in the process of producing mesityl oxide, methyl isobutyl ketone, methyl isobutyl carbinol, hexanediol, phorone, and isophorone from acetone. Diacetone alcohol can be used as Preparation of metal cleaners, wood preservatives, photographic film preservatives, pharmaceutical preservatives, antifreeze, hydraulic oil solvents, extractants and fiber finishing agents, etc. [0003] Diacetone alcohol can be widely used as a solvent for electrostatic spray paint, celluloid, nitrocellulose, fat, grease, wax and resin, etc. Therefore, the industrial wastewater produced by the above products contains a large amount of residual diacetone alcohol, and diacetone alcohol Acetol is a toxic and ...
