Abstract
The invention discloses a recycling method of abamectin fermented waste water, belonging to the technical field of the processing method of antibiotic fermented waste water. The method comprises the following steps: the fermented waste water generated in abamectin production is reused for fermenting to produce the abamectin after being processed by acid, alkali and saccharomycetes. In the recycling method of abamectin fermented waste water of the invention, the abamectin fermented waste water is processed by acid and alkali, and is processed by the saccharomycetes, and the obtained culture solution containing the saccharomycetes can be reused for fermenting to produce abamectin. Experiments prove that the fermented waste water can be used repeatedly after being processed by acid, alkali and saccharomycetes, and does not affect the fermentation valence. The application of the method can significantly improve utilization of water source, reduce environmental pollution, and does not add production cost compared with the routine waste water process method.
Description
Technical field
The invention belongs to the technical field of the treatment process of antibiotic fermentation waste water, be specifically related to abamectin fermented waste water and be used further to abamectin fermented after treatment.
Background technology
Avrmectin is a kind of agricultural antibiotic, and it promptly can also can be used for Veterinary Insecticides as agricultural insecticide.Agricultural, forestry desinsection and animal expelling parasite worldwide have been widely used in.China existing nearly 20 tame enterprises produce Avrmectin, produce closely kiloton of Avrmectin per year.Avrmectin is through liquid fermenting production by A Fuman streptomycete Streptomyces avermitilis, present stage Avrmectin the average fermentation level about 4000ug/ml, with regard to this rough calculation, 1 ton of Avrmectin of every production (Avm) produces 250 tons fermentation waste water approximately, and the fermentation waste water generation of producing 1000 tons of Avm so per year reaches 250,000 tons.These waste water were not mostly handled and just were discharged in the environment domestic present stage, and pass through anaerobism/oxygen consumption or the secondary oxygen consumption that have are handled the back discharging slightly.Certainly will cause influence like this, cause environmental pollution even, cause the waste of water resources simultaneously environment.
Summary of the invention
At the problem of prior art existence, thereby the objective of the invention is to design the technical scheme that provides a kind of environmental protection, water reuse to be worth the fermentation waste water recycle method of high conserve water resource.
Described abamectin fermented waste water recycle method is characterized in that being used further to the fermentative production Avrmectin with producing the fermentation waste water that Avrmectin produces after acid, alkali and yeast are handled, and specifically comprises following processing step:
