High-concentration pharmaceutical wastewater treatment equipment and technology with intensified treatment of functional bacteria

Abstract

The invention discloses high-concentration pharmaceutical wastewater treatment equipment and a technology with intensified treatment of functional bacteria, and belongs to the technical field of wastewater treatment. The treatment equipment comprises a physicochemical treatment system, an anaerobic treatment system and an aerobic treatment system. The treatment technology includes the following steps of physiochemical treatment, anaerobic treatment, high-load aerobic treatment, first-section A/O treatment and second-section A/O treatment. A physiochemical method and a biochemical method are used in combination, and due to the fact that the combined process of high-load aerobic treatment plug two-section A/O treatment combined technology is selected, the removable efficiency of pollutants is improved, and it is ensured that effluent quality reaches the discharging standard. Through the combined technology of the physiochemical method and the biochemical method, it can be ensured that the effluent quality of high-concentration integrated pharmaceutical wastewater reaches the standard.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to high-concentration pharmaceutical waste water treatment equipment and technology for enhanced treatment by functional bacteria. Background technique [0002] The wastewater generated in the pharmaceutical process mainly includes antibiotic wastewater, traditional Chinese medicine wastewater and chemical pharmaceutical wastewater. The production of pharmaceutical wastewater is large. The output value of the pharmaceutical industry accounts for only 1.7% of the national total industrial output value, and its wastewater discharge accounts for 2% of the national wastewater discharge. One ton of antibiotics produces an average of 150~200m³ of high-concentration organic wastewater, and the fermentation unit is low. variety, its wastewater volume has doubled; chemical and pharmaceutical wastewater has a complex composition, containing antibiotic residues, antib...
