The invention relates to a device for treating high-concentration ammonia nitrogen in pharmaceutical wastewater by using a surface activity catalyst, belonging to the field of sewage treatment. The device consists of a raw water inlet (1), an air outlet (2), a water distributor (3), an aeration device (4), a packing tube (5), a gas-water redistributor (6), an air flue (7), an effluent weir (8), an effluent collecting part (9), a high-pressure pump (10), an ejector (11) and a diaphragm type aerator (12), wherein the ejector (11) is connected with the high-pressure pump (10); the water distributor (3) is connected with the raw water inlet (1) and is positioned below the aeration device (4); the packing tube (5) is arranged inside the aeration device (4). Due to adoption of PVDF as a valve body material, the ejector is optimal in abrasion resistance, high in mechanical strength and is solid, durable, and corrosion-resisting. The device is high in practicability and high in removal rate, the production cost is saved, the removal rate of the high-concentration ammonia nitrogen wastewater which is treated by using the device provided by the invention is more than 99.9%, and thus the environment pollution is reduced.
Description
technical field [0001] The invention discloses a device for treating high-concentration ammonia nitrogen in pharmaceutical waste water with a surface active catalyst, belonging to the field of sewage treatment. 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. The 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 wastewater is a difficult problem in envi...
