The invention discloses a compound biological bacterium enzyme and a method for treating pharmacy enterprise sewage by the compound biological bacterium enzyme. The compound biological bacterium enzyme comprises protease, amylase, cellulase and lipase according to a certain weight ratio. The compound biological bacterium enzyme is used for treating antibiotic sewage of a pharmacy enterprise fermentation waste liquid, can remove antibiotic residues in the sewage by specific degradation functions, has strong adaptive capacity to the environment and has good treatment effects on various difficultly-degraded pollutants in the polluted water. The method for treating pharmacy enterprise sewage comprises pre-treatment, comprehensive biochemical treatment by the compound biological bacterium enzyme, sludge treatment discharge and product water discharge. Through the method, the product water can satisfy national sewage discharge standards. The method has the characteristics of small land occupation area, stable operation and high sewage treatment efficiency, can greatly reduce pollution of the pharmacy enterprise and can effectively remove antibiotic residues in the sewage. |
