Abstract

The invention belongs to the technical field of waste water treatment, and particularly discloses a method for reducing toxicity of antibiotic wastewater through flash evaporation. The method comprises the steps that (1) waste water containing antibiotic is put in a high-pressure tank, the waste water in the high-pressure tank is pressurized and heated, and the pressure in the high-pressure tank is 0.3-0.4 Mpa; (2) the waste water in the pressure state in the step (1) is released in a negative-pressure tank, the pressure in the negative-pressure tank is 0.02-0.05 Mpa, and when flowing into thenegative-pressure tank, the waste water is stirred, and waste gas is generated; (3) the waste water in the negative-pressure tank in the step (2) is drained out, and meanwhile, the waste gas in the negative-pressure tank is pumped out. The method is mainly used for reducing toxicity of antibiotic in the waste water, and the problem that the waste water containing antibiotic can easily pollute theenvironment is solved.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and specifically discloses a method for reducing the toxicity of antibiotic waste water through flash evaporation. Background technique [0002] Antibiotics are compounds produced by microorganisms, plants, and animals during their life processes. They have the ability to selectively inhibit or kill other microorganisms or tumor cells at low concentrations. Important chemicals for animal and plant diseases. [0003] Most of the antibiotics produced in China are extracted through fermentation process. The production process includes: microbial fermentation, filtration, extraction and crystallization, chemical extraction, refining and other processes. In the process of extracting antibiotics, waste water will be produced, which contains more antibiotics that are difficult to degrade, causing serious pollution to the environment. Contents of the invention [0004] The purpose of t...
