A treatment system and treatment method for antibiotic fermentation wastewater

Abstract

The invention discloses a treatment system and a treatment method for antibiotic fermented wastewater. The system comprises a coagulation reaction pond, a first settling pond, a first neutralization pond, an anaerobic pool, an aerobic pond, a second settling pond, an acid adjusting pond, a Fenton reaction pond, a second neutralization pond, a third settling pond and an oxidizing pond which are connected, wherein stirrers are arranged in the first neutralization pond, the second neutralization pond and the Fenton reaction pond; a first coagulation stirring device is arranged in the coagulation reaction pond; and suspended carriers are arranged in the anaerobic pool and the aerobic pond, and the aerobic pond is connected to an aerating device. The system and method disclosed by the invention can effectively reduce COD in pharmaceutical wastewater, improves the biodegradability of a wastewater effluent, and is good in wastewater treatment effect; and the equipment is good in impact resisting effect, can be suitable for relatively large water fluctuation generated by the pharmaceutical wastewater, and is long in service life.

Description

technical field [0001] The invention belongs to the technical field of industrial wastewater treatment, and in particular relates to a treatment system and method for antibiotic fermentation wastewater. Background technique [0002] With the continuous growth of the economic level, the total amount of pharmaceutical wastewater is also increasing, so the demand for wastewater treatment is also increasing. Antibiotics will produce a large amount of wastewater in the pharmaceutical process. These wastewaters have complex water quality components, large impact loads, and many toxic and harmful substances. The existing traditional processes of urban sewage plants cannot cope with this type of wastewater, and even this type of wastewater is discharged into cities and towns. Sewage treatment facilities may affect the normal operation of urban sewage plants. [0003] Existing pharmaceutical wastewater treatment devices usually use coagulation and aerobic aeration treatment processe...

Antibiotics will produce a large amount of wastewater in the pharmaceutical process. These wastewaters have complex water quality components, large impact loads, and many toxic and harmful substances. The existing traditional processes of urban sewage plants cannot cope with this type of wastewater, and even this type of wastewater is discharged into cities and towns. Sewage treatment equipment may affect the normal operation of urban sewage plants

[0003] Existing pharmaceutical wastewater treatment devices usually use coagulation and aerobic aeration treatment processes to remove COD in wastewater (chemical oxygen demand: refers to the amount of COD consumed when a certain strong oxidant is used to treat water samples under certain conditions. The amount of oxidant. It refers to an indicator indicating the content of reducing substances in water. The reducing substances in water include various organic matter, nitrite, sulfide and ferrous salt); however, the COD of wastewater treated in this way is still high, which can be Poor biochemical properties, difficult to meet wastewater treatment standards
