Problems solved by technology

Among them, the dosage of chemical reagents in the process of physical and chemical pretreatment of wastewater is large, so this method not only has high operating costs, but also the chemical reagents added are likely to cause secondary pollution to the environment; the operating conditions of the anaerobic biological treatment process are strict and the reaction time is long. , and the toxic substances in the wastewater have inhibitory or poisonous effects on anaerobic microorganisms, and the quality of the effluent is poor and has a strong odor; after conventional aerobic biological treatment, the water quality still cannot meet the discharge requirements or can not be reused even though it meets the standards, causing serious damage to water resources. waste

Embodiment 1

[0021] Such as figure 1 Shown: the method of the present invention can ensure that the treated effluent reaches the standard stably, and has been successfully operated on many engineering examples. The specific process is as follows:

[0022] (a) Antibiotic waste water passes through the grid and removes part of the suspended matter and enters the regulating pool. After entering the iron-carbon micro-electrolytic cell from the regulating pool, add homogeneous granular fillers and mix evenly for micro-electrolysis. The amount of homogeneous granular fillers added is 4 times the flow rate of waste water.

[0023] Wherein, the above-mentioned homogeneous particle filler is formed by iron powder, carbon powder and bonding material; the composition ratio of the two components of the iron powder and carbon powder is 1:2; the addition amount of the bonding material is 5 %.

[0024] (b) After the wastewater enters the coal / natural gas indirect liquefaction tank from the iron-carbon...

Embodiment 2

[0029] The method of the present invention handles the engineering application of a certain company's production wastewater:

[0030] (a) Antibiotic waste water passes through the grid and removes part of the suspended matter and enters the regulating pool. After entering the iron-carbon micro-electrolytic cell from the regulating pool, add homogeneous granular fillers and mix evenly for micro-electrolysis. The amount of homogeneous granular fillers added is 6 times the flow rate of waste water.

[0031] Wherein, the above-mentioned homogeneous granular filler is formed of iron powder, carbon powder and bonding material; the composition ratio of the two components of the iron powder and carbon powder is 2:4; the added amount of bonding material is 10%.

[0032] (b) After the wastewater enters the coal / natural gas indirect liquefaction tank from the iron-carbon micro-electrolysis tank, it is oxidized by adopting a hierarchical reaction method, and the Fenton oxidant is added to...

Embodiment 3

[0037] The method of the present invention handles the engineering application of a certain company's production wastewater:

[0038] (a) Antibiotic waste water passes through the grid and removes part of the suspended matter and enters the regulating pool. After entering the iron-carbon micro-electrolytic cell from the regulating pool, add homogeneous granular fillers and mix evenly for micro-electrolysis. The amount of homogeneous granular fillers added is 5 times the flow rate of waste water.

[0039] Wherein, the above-mentioned homogeneous granular filler is formed by iron powder, carbon powder and bonding material; the composition ratio of the two components of the iron powder and carbon powder is 3:5; the addition amount of the bonding material is 7 %.

[0040](b) After the wastewater enters the coal / natural gas indirect liquefaction tank from the iron-carbon micro-electrolysis tank, it is oxidized by adopting a hierarchical reaction method, and the Fenton oxidant is a...

Abstract

The invention discloses a treatment method of antibiotic production wastewater. The innovation point is as follows: through an adjusting tank, antibiotic successively enters an iron-carbon micro-electrolysis tank, an FT oxidation tank, a coagulative precipitation tank, an air floatation tank, a treating tank equipped with an anaerobic internal circulation reactor, an upflow sludge blanket filtering basin, a hydrolysis acidification pool, a contact aeration basin and a secondary sedimentation tank so as to undergo recovery processing. According to the treatment method of antibiotic production wastewater, improved iron-carbon micro-electrolysis and improved coal / natural gas indirect liquefaction FT oxidation technologies are adopted for pretreatment, so as to destroy and degrade hardly-degraded and toxic organic pollutants in wastewater. Thus, toxicity is destroyed and water concentration is reduced while biodegradable performance of pollutants in wastewater is improved. Favorable conditions are created for follow-up biochemical treatments, and treatment efficiency and effluent quality standard are raised.

Description

technical field [0001] The invention relates to a treatment method for antibiotic production wastewater, belonging to the field of wastewater treatment. Background technique [0002] Antibiotic production includes microbial fermentation, filtration, extraction and crystallization, refining, refining and other processes. Wastewater has the characteristics of high COD concentration, complex components, and the presence of biologically toxic substances. It is one of the more difficult toxic organic wastewater to treat. [0003] At present, there are more than 300 enterprises producing antibiotics in my country, producing 70 varieties of antibiotics accounting for 20% to 30% of the world's output. The output is increasing year by year, and China has now become one of the major antibiotic preparation countries in the world. The antibiotic production process includes microbial fermentation, filtration, extraction, crystallization, refining, refining and other processes. The waste...
