Embodiment 1

[0053] A pharmaceutical factory discharges 170m of pharmaceutical wastewater per day 3 , its wastewater mainly comes from the pretreatment and extraction process of traditional Chinese medicine, mainly organic pollution, its main components are hydrocarbon organic matter, plant acid, plant alkaloid, polysaccharides, lignin, pigment, etc., the main pollution factor is COD , BOD, SS and chroma etc. It has the characteristics of high concentration of organic pollution, difficulty in biochemical degradation, and large fluctuations in water quality.

[0054] Adopt the chemical synthesis pharmaceutical wastewater treatment system and method of the present invention, and add compound biological enzyme, the compound biological enzyme is composed of 2% alcohol dehydrogenase, 4% pectinase, 6% α-amylase, 3% by weight % β-amylase, 3% xylanase, 8% cellulase, 9% catalase, 2% β-glucanase, 3% glucoamylase, 3% polyphenol oxidase, 6% pancreatic Made of lipase, 3% neutral protease, 5% laccase,...

Embodiment 2

[0058] A pharmaceutical factory discharges 600 tons of pharmaceutical wastewater per day, and the wastewater produced contains a large amount of toxic organic substances, such as side chain fats, petroleum ether, acetone, methanol, ethanol, methylene chloride, toluene and various acids and alkalis, as well as cephalosporins Antibiotic residues. This type of wastewater has complex components, high organic content, large molecular weight, toxic substances and antibiotics in the water have a strong inhibitory effect on the biochemically treated bacteria, and conventional treatment methods are difficult to achieve ideal treatment effects. Adopt the novel chemical synthesis pharmaceutical wastewater treatment device and method of the present invention, and add compound biological enzyme, the compound biological enzyme is composed of the following weight percentages: 4% alcohol dehydrogenase, 5% pectinase, 5% α-amylase , 2% β-amylase, 2% xylanase, 5% catalase, 3% glucoamylase, 5% po...

Embodiment 3

[0060] A biochemical pharmaceutical company produces 400 tons of pharmaceutical wastewater per day. It has a wastewater treatment system that uses aerobic-sedimentation-filtration process to treat wastewater, and the effluent cannot meet the relevant discharge standards. The wastewater generated by the project mainly comes from production process drainage, cleaning equipment wastewater, resin regeneration wastewater, reverse osmosis concentrated water, circulating cooling water, workshop floor cleaning wastewater, and domestic sewage, including heparin sodium, benzethonium chloride, sodium metabisulfite, ethanol , methanol, dichloromethane and brine, etc. The wastewater has high salt content and high concentration of organic matter, which is a high-concentration refractory organic wastewater. Its wastewater has the characteristics of high salt content, high concentration of organic matter, difficult biochemical degradation, and large fluctuations in water quality. Adopt novel ...

Abstract

The invention discloses a chemical synthetic pharmaceutical wastewater treatment device. The device comprises a pre-exposition adjustment pond, an enzyme supplementation anaerobic pond, an enzyme supplementation contact oxidation pond, an MBR biochemical pond and a sludge concentration pond; a reflux pipeline is connected between the pre-exposition adjustment pond and the enzyme supplementation anaerobic pond, a reflux pipeline is connected between the enzyme supplementation anaerobic pond and the enzyme supplementation contact oxidation pond, and a reflux pipeline is connected between the enzyme supplementation contact oxidation pond and the MBR biochemical pond; a biological suspension ball and an oxidation reduction potential (ORP) control system are arranged in the pre-exposition adjustment pond; an ORP control system, an MLSS online monitor and a DO online monitor are arranged in the MBR biochemical pond. The invention further discloses a sewage treatment method adopting the device. The method is resistant to high salinity, high in COD removal rate and remarkable in decoloration function, and the decoloration effect of wastewater high in treatment difficulty and the degradation effect of organic matter hard to degrade are remarkable. Moreover, the treatment cost is low, operation is simple, and the effluent quality index is stable; a composite biological enzyme obtained through the method can keep activity for a long term, and therefore the system has a long-lasting treatment effect.

Description

technical field [0001] The invention belongs to the field of environmental engineering, and in particular relates to a treatment device and method for chemically synthesized pharmaceutical wastewater. Background technique [0002] With the development of synthetic pharmaceutical industry, chemical pharmaceutical wastewater has become one of the serious pollution sources. The pharmaceutical industry is one of the 12 key industries in the national environmental protection plan. Due to the wide variety of chemical components, a variety of raw materials are used in the pharmaceutical production process, the production process is complex and changeable, and the components such as wastewater produced are also very complicated. Due to different pharmaceutical products and different production processes, there are great differences. The production process is characterized by long processes, complex reactions, and many by-products. The reaction raw materials are often solvent substa...
