Embodiment

[0035] A combined treatment process for bioengineering pharmaceutical wastewater, comprising a pretreatment step and a biochemical treatment step, wherein the pretreatment step includes:

[0036] (1) Remove suspended solids through a filter device;

[0037] (2) Add concentrated sulfuric acid to the wastewater treated in step (1) to make the pH of the wastewater = 1-2, keep the temperature of the wastewater at 60-80°C, and keep the temperature for 1-2h, and the workers will unify the volatilized gas After condensation and collection, use the existing liquid separator to separate, take out the organic layer for fuel combustion, and dump the water layer;

[0038] (3) adding unslaked lime to the waste water treated in step (2), adjusting the water quality of the waste water to be pH=6-8, then cooling the waste water to minus 5-10°C;

[0039] (4) Filter the wastewater treated in step (3) with a filter device, then heat the wastewater, keep the temperature of the wastewater at 80-1...

Abstract

The application of the present invention belongs to the technical field of treatment of water, waste water, sewage or sludge, and specifically discloses a combined treatment process for bioengineering pharmaceutical wastewater, including a pretreatment step and a biochemical treatment step. The pretreatment step includes: (1) passing through a filter device Remove suspended solids; (2) add concentrated sulfuric acid to the waste water after step (1) treatment, make the pH of waste water=1-2, the waste water temperature remains on 60-80 ℃; (3) to step (2) after treatment Add quicklime to the waste water to adjust the water quality of the waste water to pH=6-8, and then cool the waste water; (4) filter the waste water treated in step (3), then heat the waste water, and keep the waste water temperature at 80-120°C (5) return the wastewater treated in step (4) to normal temperature, and filter. The processing steps of the process are simple, the processing time is short, and secondary pollution is not easy to be caused.

Description

technical field [0001] The invention belongs to the technical field of water, waste water, sewage or sludge treatment, and specifically discloses a bioengineering pharmaceutical waste water combined treatment process. Background technique [0002] my country's pharmaceutical industry is mainly divided into bioengineering pharmaceuticals, chemical pharmaceuticals and Chinese herbal medicine pharmaceuticals. Among them, the wastewater discharged from bioengineering pharmaceuticals has the following characteristics: [0003] (1)COD cr high concentration; [0004] (2) The concentration of suspended solids (SS) is high, mainly the residual culture substrate of fermentation and the microbial cells of fermentation; [0005] (3) Contains various biologically active substances (such as antibiotics and Mycobacterium bovis with live virus, influenza virus, rabies virus, etc.), amino acids and some drug intermediates. Since the biologically active substances in this type of wastewate...
