Embodiment 1

[0018] Embodiment 1: a kind of advanced treatment technology of fermented class antibiotic waste water, as figure 1 , figure 2 As shown, firstly, the fermentation antibiotic wastewater is biochemically treated: three steps: hydrolytic acidification, anaerobic reaction and aerobic reaction. The conditions for hydrolytic acidification are that the pH of the wastewater is between 5-9, and the temperature of the wastewater is 20-40°C. A large number of microorganisms are required to participate in the reaction in the hydrolytic acidification tank, and the main purpose is to improve the biodegradability of wastewater; the conditions for anaerobic reaction are that the pH of the influent is between 6.8-7.6, and the temperature of the wastewater is optimal at 30-36°C, which requires a large amount of anaerobic reaction. Microbes participate in the reaction, including methanogenic bacteria, acetogenic bacteria, etc. The conditions for aerobic reaction are that the pH of the wastewate...

Abstract

The invention relates to the technical field of wastewater treatment, in particular to an advanced treatment process for fermentation antibiotic wastewater. The advanced treatment process comprises the following steps: the fermentation antibiotic wastewater subjected to biochemical treatment is sent into a coagulation reaction tank, and a coagulant and a coagulant aid are added for a reaction; effluent of the coagulation reaction tank is subjected to precipitation separation treatment in a coagulative precipitation tank, and floc precipitates obtained after precipitation are sent into a sludge thickener; effluent of the coagulative precipitation tank is sent into a catalytic oxidation reaction tank and subjected to a Fenton catalytic oxidation reaction; effluent of the catalytic oxidation reaction tank is sent into a catalytic oxidation precipitation tank for precipitation separation treatment, flocs in the effluent obtained after an oxidation reaction are precipitated in the precipitation tank, and precipitated flocs enter the sludge thickener; effluent of the catalytic oxidation precipitation tank enters a two-membrane process desalter for desalting treatment, and the fermentation antibiotic wastewater treated with the process is high in quality and can meet the requirement for reuse of reclaimed water.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an advanced treatment process for fermented antibiotic wastewater. Background technique [0002] Fermented antibiotic wastewater contains a large amount of organic pollutants and salt that are difficult to biodegrade. If only biochemical treatment is used, the biodegradable COD in the fermented antibiotic wastewater after biochemical treatment is almost completely removed by microorganisms, but the biodegradable COD is almost completely removed. Pollutants still remain in the wastewater, and it is difficult for the effluent to meet the requirements of the "Discharge Standards for Pollutants in the Fermentation Pharmaceutical Industry" (GB21903-2008), resulting in the discharge of wastewater that cannot meet the standards. According to investigations, most of the commonly used advanced wastewater treatment technologies are electrolysis technology, ozone oxidation tech...
