Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically an integrated equipment for treating biomedical research and development wastewater. Background Technology

[0002] The biopharmaceutical industry, which is engaged in the production of in vitro diagnostic reagents, stem cell transplantation diagnostic reagents, pilot production and R&D, often has a small scale of wastewater treatment. The main types of wastewater discharged are: culture vessel and reaction vessel cleaning wastewater, sterilization wastewater, disinfection wastewater, RO preparation concentrate, etc., with relatively low pollutant concentrations. Common characteristic pollutant indicators are: COD, ammonia nitrogen, E. coli and SS. The physicochemical method of neutralization + coagulation flocculation sedimentation + disinfection can effectively remove SS and E. coli pollutants from wastewater.

[0003] The wastewater generated by the aforementioned enterprises is usually not large in volume and is generally treated using physicochemical methods. These enterprises have tight deadlines for wastewater treatment, and the traditional concrete construction method results in long construction periods. Furthermore, many biopharmaceutical R&D companies lease factory buildings in industrial parks later in the process, without considering wastewater treatment facilities during the initial construction phase. Therefore, it is not feasible to rebuild wastewater treatment structures using traditional civil engineering methods. Thus, it is essential to develop an integrated biopharmaceutical R&D wastewater treatment system that combines wastewater collection, chemical reaction and sedimentation, clean water disinfection and discharge, chemical dosing, sludge dewatering, and automatic control. This system would allow for more efficient and rational use of space, integrated assembly, saving floor space, and shortening the construction cycle of environmental protection projects.
