Abstract

The invention belongs to the technical field of pharmaceutical wastewater treatment, and particularly relates to a device and method for treating high-concentration insoluble organic pharmaceutical wastewater. According to the method, high-concentration pharmaceutical wastewater and low-concentration pharmaceutical wastewater are separately treated, the high-concentration pharmaceutical wastewater is treated by adopting a mode combining physicochemical treatment, advanced oxidation process, hydrolysis acidification method and TIC anaerobic reaction tower to remove massive COD, BOD5, SS and the like in water; and the low-concentration organic wastewater is subjected to physicochemical pretreatment to improve the biodegradability of wastewater, and flows into an A / O process, a secondary sedimentation tank, a reaction tank, a final sedimentation tank and a clear water tank to remove ammonia, nitrogen and the like in the water until the water can be discharged at standard. The method has the advantages of stable system operation, remarkable organic matter removing effect, low energy consumption, high load, small floor area and the like, and is applicable to wastewater treatment of large, medium and small sized pharmaceutical factories.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a high-concentration, refractory organic pharmaceutical wastewater treatment device and treatment method. Background technique [0002] Pharmaceutical industry wastewater mainly includes four categories: antibiotic production wastewater, synthetic drug production wastewater, Chinese patent medicine production wastewater, and washing water and flushing wastewater in the production process of various preparations. Pharmaceutical industrial wastewater is characterized by complex components, high organic content, high toxicity, deep color and high salt content, especially poor biochemical properties, and intermittent discharge, which is difficult to treat industrial wastewater. With the development of my country's pharmaceutical industry, pharmaceutical wastewater has gradually become one of the important sources of pollution. How to deal with this type of wastew...
