Non-antibiotic pharmaceutical wastewater treatment process

Abstract

The invention discloses a non-antibiotic pharmaceutical wastewater treatment process which is characterized by comprising the following steps: I. separating out grease in non-antibiotic pharmaceutical wastewater by virtue of an oil separator so as to obtain grease and wastewater a; II. leading the wastewater a into a collecting tank and preprocessing the wastewater a by virtue of a modified Fe-C microelectrolysis system so as to obtain processed wastewater b; and III. processing the wastewater b through the following processing tanks sequentially: a primary settling tank, a regulating tank, an up-flow anaerobic sludge blanket (UASB) anaerobic tank, an activated sludge tank and a biological contact oxidation tank, and settling sludge by virtue of a secondary settling tank until discharged water reaches a discharge standard. In processing non-antibiotic pharmaceutical wastewater, the process disclosed by the invention can be used for achieving high capacities of pollution resistance and resistance to impact load, avoiding the addition of a flocculating agent and the like and keeping a processing station at a relatively low running cost, and the quality of the discharged water can be kept within a stable range as required; and the wastewater treatment has a broad application prospect.

Description

technical field [0001] The invention relates to a non-antibiotic pharmaceutical wastewater treatment process. Background technique [0002] With the development of society, my country's pharmaceutical industry is developing faster and faster. The sewage produced by various pharmaceutical companies is due to its different production, pollutant diversity and differences, including antibiotic production wastewater, non-antibiotic production wastewater, and most pharmaceutical wastewater. Its complex structure, toxic, harmful and biodegradable organic substances cause serious pollution to water bodies. Among them, there are many kinds of non-antibiotic drugs. The wastewater is characterized by complex components, high content of organic matter, usually with average or poor biodegradability, and is mostly difficult to treat. [0003] Non-antibiotic pharmaceutical industrial wastewater is characterized by complex components, high organic content, and difficult treatment, especiall...
