NOVELTY - Treatment of biopharmaceutical wastewater comprising fermentation wastewater and extraction wastewater comprises subjecting fermentation wastewater and extraction wastewater to aeration regulation, hydrolysis acidification, air floatation and demand aeration tank-intermittent aeration tank (DAT-IAT) treatment in series. Coagulant is added to wastewater to deposit suspended matter and obviously reduce inhibition of clear liquid on microbe. Two-phase anaerobic effluent enters sequencing batch reactor to undergo sequencing batch activated sludge process.    USE - Method for treating biopharmaceutical wastewater.    ADVANTAGE - The method overcomes the influence of microbial inhibited factor and ensures wastewater treatment effect.    DETAILED DESCRIPTION - Treatment of biopharmaceutical wastewater comprises subjecting fermentation wastewater and extraction wastewater to aeration regulation, hydrolysis acidification, air floatation and demand aeration tank-intermittent aeration tank (DAT-IAT) treatment in series. The fermentation wastewater is mixed with fermentation residue and microbial bacteria, and the content of suspended matter in fermentation wastewater is high such that it has strong inhibiting action on some microbes. Coagulant is added to wastewater to deposit suspended matter and obviously reduce inhibition of clear liquid on microbe. The extraction wastewater is wastewater obtained by extracting drug ingredients from filtrate by a chemical method, and the water contains chemical agents added in extracting, and some substances can inhibit the growth of methanogenesis microbe, thus anaerobic treatment in the process adopts the two-phase anaerobic treatment where anaerobic acidification is performed, and the wastewater, from which the inhibiting substance to generate methanogens by an adsorption tower at low pH is removed, enters an anaerobic methanator, under the action of methane bacteria, and the pollutant in water is degraded and the methane gas is generated. Two-phase anaerobic effluent enters sequencing batch reactor to undergo sequencing batch activated sludge process.
