Problems solved by technology

[0003] Many antibiotic wastewater treatment processes reported in the literature are almost all evaluating the treatment effect of wastewater based on the removal of wastewater COD as an index, but did not pay enough attention to the antibiotic compounds contained in wastewater, and the treated wastewater still contains antibiotic compound

Abstract

The invention discloses a method and a device for deeply treating antibiotic pharmaceutical wastewater based on magnetic Fenton-like resin. The device comprises a coagulative precipitation tank, a Fenton-like reactor, an anaerobic baffle plate reactor, an aerobic biological contact oxidation tank, a sedimentation tank, a magnetic resin Fenton-like oxidation tank and a resin adsorption tower which are sequentially communicated by virtue of pipelines. By using the method and the device, the antibiotic pharmaceutical wastewater can be deeply treated; and effluent obtained after the antibiotic pharmaceutical wastewater is treated by using the method and the device disclosed by the invention can stably reach up to the emission limit regulated by Fermented Pharmaceutical Industrial Water Pollutant Emission Standard (GB21903-2008).

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a method and device for advanced treatment of antibiotic pharmaceutical wastewater based on magnetic Fenton resin. Background technique [0002] Antibiotics are important chemical drugs for humans to control various diseases. At present, in antibiotic production, there are still many technical difficulties in the screening and production of antibiotics, strain selection, etc., resulting in many problems such as low raw material utilization rate, low refining purity, high residual antibiotic content in wastewater, and serious environmental pollution. Antibiotic pharmaceutical wastewater mainly comes from production processes such as fermentation, filtration, extraction and crystallization, chemical extraction, and refining. The wastewater has high concentration of COD, BOD and ammonia nitrogen, strong acidity and strong biological toxicity. At present, the treatme...
