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...

Problems solved by technology

[0004] China's ZL201210295894.2 proposed the combined process of "four-effect evaporation device-coagulation sedimentation-two-phase anaerobic reaction + multi-functional aerobic reaction" to treat high-salinity and high-ammonia-nitrogen pharmaceutical wastewater, and organically combined a number of advanced wastewater treatment technologies In general, it has the advantages of simple operation and management and easy control, but the reaction process of this process is relatively complicated, the hydraulic retention time is long, and the ammonia nitrogen and electrical conductivity of pharmaceutical wastewater are much higher than the ammonia nitrogen ≤ 90mg / L in the water quality index of the implementation case , Sulfate = 300mg / L, so this process does not reflect the superiority in the removal effect of high ammonia nitrogen and high conductivity

[0005] To sum up, according to the complexity of wastewater, it is difficult to achieve the ideal treatment effect by a single treatment method alone. How to optimize the wastewater treatment process of the combined process by focusing on the biochemical treatment process combined with physical and chemical methods to realize pharmaceutical The up-to-standard discharge of wastewater has become a hot and difficult point in the research of pharmaceutical wastewater treatment technology
