Problems solved by technology

Due to the presence of cell walls and / or cell membranes in microorganisms, reaction substrates (pollutants) need to pass through cell walls and / or cell membranes to interact with active enzymes in microorganisms, which greatly reduces the treatment efficiency

Abstract

The invention discloses a treatment process of antibiotic pharmacy waste water, which comprises the steps of pretreatment of the antibiotic pharmacy waste water, immobilized bio-enzyme treatment, immobilized activated sludge treatment and the like. The method enables the immobilized enzyme technology and the immobilized activated sludge technology to be combined and applied to treatment of the antibiotic waste water and improves the effects by 2-3 times compared with a method singly using an immobilized microorganism technology or a biological reinforcement technology. The method does not usespecial-effect genetic engineering bacteria which antibiotics can tolerate or natural bacteria subjected to pure culture and separation, and the environmental risks of formation and diffusion of superbacteria are reduced.

Description

technical field [0001] The invention relates to a waste water treatment process, in particular to a treatment process for antibiotic pharmaceutical waste water. Background technique [0002] Antibiotic pharmaceutical wastewater is a kind of high-concentration organic wastewater with complex components, high chroma, refractory substances and biological toxic substances. Residual antibiotics and solvents in wastewater have a certain inhibitory effect on microorganisms. At the same time, the refractory biodegradable substances produced by biological fermentation and metabolism in wastewater lead to poor comprehensive biodegradability. Therefore, it is important to develop economical and effective antibiotic wastewater treatment technology. significance. [0003] Antibiotic production technology is mainly based on biosynthesis by microbial fermentation. The main sources of wastewater are crystallization waste mother liquor, acid-base wastewater and organic solvent wastewater in...
