Introduction to the results:

As a special hazardous waste, antibiotic residue has been included in the revised National Hazardous Waste List in 2008, and its treatment and disposal has become a bottleneck in the development of the pharmaceutical industry.

This research developed an integrated technology of "efficient pretreatment + enhanced biological anaerobic" to treat antibiotic residue such as penicillin, cephalosporins, oxytetracycline, and streptomycin, effectively achieving the reduction of antibiotic residue. Resource and harmless treatment requirements.

Taking penicillin bacterial residue as an example, an integrated technology of "hot water hydrolysis of bacterial residue + combined anaerobic digestion of bacterial residue and sludge" was developed. The solid content of the feed in the pilot system was 5.~7%, organic load 3~4 kgCOD/m3. d, digestion time 20 days, solid reduction rate>50%, biogas output>450m3/t dry matter, and penicillin residue in biogas residue was not detected. The indicators of biogas residue are lower than the standard values of the "Identification Standards for Hazardous Wastes"(GB5085.7 -2007); the fertilizer efficiency components of biogas residue meet the indicator requirements of "Organic Fertilizer"(NY 525-2002).

This research results have made major breakthroughs and innovations in the treatment process of antibiotic residue, providing technical support for effectively controlling the environmental risks of antibiotic residue, and have important reference value for the treatment of other antibiotic residue.

Application areas:

Solid waste treatment and resource utilization in the field of environmental protection are suitable for the treatment of antibiotic fermentation residue in the effluent of fermentation antibiotic production enterprises.

There are more than 300 antibiotic production companies in my country, with more than 70 types of antibiotic products, accounting for 20% of the world's output~30%, it is the world's largest producer of antibiotic raw materials. After antibiotic residue was included in the National Hazardous Waste List, its treatment and disposal has become a bottleneck in the development of the pharmaceutical industry.

Using this technology can realize the resource and harmlessness of antibiotic residue, completely solve the bottleneck problems that restrict the development of the pharmaceutical industry, and promote the sustainable development of enterprises. The market prospects are broad.
