Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing.

[0030] The advanced treatment process of fermentation pharmaceutical wastewater, the effluent of the biochemical treatment secondary sedimentation tank is directly pumped into the bottom of the Fenton-like reactor without adjusting the pH, and passes through the composite catalyst bed from bottom to top. The catalyst is uniform and granular, and the flow rate is controlled so that The expansion rate is around 30% to reduce loss. The organic matter in the wastewater was added to the FeSO 4 ·7H 2 O and H 2 o 2 Degradation is carried out under the joint action of 4 ·7H 2 O dosage is 0.2-0.4mmol / L, 30% (mass concentration) H 2 o 2 The amount added is 2-3mmol / L. In order to strengthen the removal of COD and blow off a small amount of unreacted H 2 o 2, Fenton-like reactor effluent is aerated, and the aeration time is 20 minutes.

[0031] The effluent from the Fent...

Abstract

The invention belongs to the technical field of waste water treatment, particularly relates to an advanced treatment process for fermented pharmaceutical waste water, which comprises the following steps: placing the pharmaceutical waste water after being subject to bio-chemical treatment into a Fenton reactor to perform oxidation treatment, and performing coagulating precipitation, ultra-filtration and reverse osmosis. The advanced treatment process for the fermented pharmaceutical waste water overcomes the shortcoming that limitation of potential of hydrogen (pH) in a Fenton method needs to be adjusted in the waste water treatment of biopharmaceutical industry, operation is simple, waste water treatment efficiency and reuse rate are high, and operating cost is low.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an advanced treatment process for fermented pharmaceutical wastewater. Background technique [0002] Biopharmaceutical wastewater has complex components, high concentration, high toxicity, heavy color and odor, and contains refractory substances and inhibitory drugs, so it is extremely difficult to treat. In order to reduce the treatment cost, most domestic biopharmaceutical enterprises currently focus on the anaerobic-aerobic process, but the traditional UASB, UBF and ABR reactors have low treatment capacity, and with the "Fermentation Pharmaceutical Industry Water Pollutants With the implementation of the "Emission Standard" (GB21903-2008), a single secondary biological treatment can no longer meet the requirements, and advanced treatment must be carried out, and it is best to reuse the quality to meet the requirements of future clean production.
