Embodiment Construction

[0020] The system of the present invention is composed of the following steps: before the expanded granular sludge bed, an oil separator, an adjustment tank, a micro-electrolysis tank, a Fenton catalytic oxidation tower, a horizontal flow primary sedimentation tank, a comprehensive adjustment tank and a hydrolysis acidification tank are arranged in sequence; After the granular sludge, an A / O tank, a two-stage BCO tank, a BAF tank, a secondary sedimentation tank, a coagulation tank, an air flotation tank, and a final sedimentation tank were established in turn.

[0021] The advective primary sedimentation tank, secondary sedimentation tank, coagulation tank, BAF tank, and final sedimentation tank are connected with the sludge thickening tank, so that the sludge in the five tanks is discharged into the sludge thickening tank, and the sludge thickening tank is pressed against the plate and frame. The filter is connected, the sludge is dehydrated by the plate and frame filter press...

Abstract

The invention provides a micro-electrolysis-Fenton-EGSB-A/O-BCO-BAF-coagulation treatment pharmaceutical wastewater system. The system composition comprises an oil separation pool, a regulation pool, a micro-electrolytic reaction pool, a Fenton catalytic oxidation tower, a horizontal flow type primary sedimentation pool, an integrated regulation pool, a hydrolysis acidification pool, a swell granule sludge bed, an anoxia/aero-biotic pool, a two-stage biological contact oxidation pool, and a secondary sedimentation pool, a biological aerated filter pool, a coagulating pool, an air floating tank and an end sedimentation tank; wherein 200t/d low concentration pharmaceutical and 50t/d domestic sewage are input to the integrated regulation pool and fully mixed with wastewater, after the dilution, the COD concentration is reduced, and the biodegradability of the wastewater is increased, after jointly going into the follow-up process system for processing, the wastewater reaches the standard and is discharged; the flat flow type primary sedimentation pool, the secondary sedimentation pool, the coagulating pool, the BAF pool and the end sedimentation and the sludge concentration are connected, and are connected with the plate-and-frame press filter machine; the sludge of each pool is collected to a sludge concentrated pool, after being concentrated then dehydrated by the plate-and-frame press filter machine, finally the sludge cakes are transported to the outside. The system is stable in efficiency, strong in shock resistance load ability.

Description

technical field [0001] The invention relates to a micro-electrolysis, a Fenton oxidation tower, an expanded granular sludge bed (EGSB), an anoxic / aerobic pool (A / O), a two-stage biological contact oxidation pool (BCO), a biological aerated filter ( BAF) and a coagulation tank combined treatment system for pharmaceutical wastewater, belonging to the field of environmental science and engineering technology. Background technique [0002] In recent years, my country's pharmaceutical industry has developed rapidly. There are a large number of pharmaceutical companies, producing tens of thousands of drugs and nearly one million tons of pharmaceuticals each year. The amount of pharmaceutical wastewater is large, but the average annual treatment rate is less than 30%. Due to the complex composition, high toxicity, high chroma, difficult biodegradation, and large changes in water quality and quantity of pollutants in pharmaceutical wastewater, it is one of the more difficult types o...
