By the Chinese center for disease control and prevention, including infectious disease control and prevention, virus disease control and prevention, sexually transmitted diseases such as HIV/AIDS prevention and control center, animal center multiple experimental research activities building, there are 200 biological safety laboratory. The waste water and waste water produced by biological laboratories often contain various pathogenic microorganisms, such as bacteria, viruses, fungi and parasites, which are of great harm. Without strict sterilization treatment, it will be possible to contaminate the environment, cause epidemic disease and seriously endanger human health.
The Chinese center for disease control and prevention has built a laboratory sewage treatment plant for the treatment of wastewater and the safety of the environment. After more than 4 years of actual operation management, the water quality is good and stable. The process and effect of wastewater treatment are analyzed as follows.
Objects and methods
Laboratory wastewater produced mainly for laboratory experiments wastewater, composition is pathogenic microorganisms, disinfection detergents, chemicals, such as washing wastewater, sewage must be inactivated through high temperature and high pressure device for a rear can row to biological inactivated treatment experiment sewage pipes, sewage treatment station into the experiment. General laboratory sewage is directly drained into the experimental sewage pipe and into the experimental sewage treatment station.
The sewage treatment technology on the Chinese center for disease control and prevention, with polyaluminium chloride and sodium hypochlorite disinfectant, the processed water samples testing results show that the effluent water quality fully meet GB18466-2005 "water pollutant discharge standard of medical institution". That BSL - 2 laboratory using a high temperature and high pressure within the research activities building inactivated, park laboratory wastewater treatment station centralized secondary treatment process, general laboratory using the process of laboratory for central treatment of sewage treatment station, from the perspective of biological safety, is currently the most safe and reliable manner.
China’s rapid economic growth has made great achievements in all its construction, but it has also paid the price of resources and environmental destruction. The national "twelfth five-year plan" has made clear the goal of energy conservation and emission reduction, among which the increase of water pollution depth management is one of the key points of the project. The national center for disease control and prevention has been increasing its displacement, and the comprehensive utilization of wastewater treatment will become one of the research directions for resource development of the CDC.
The water quality of China’s disease control and prevention control center has reached the standard of landscaping. Sewage has become a useful resource, economy, environment and social benefit, which is in line with the requirements of establishing an energy-efficient society.
