Academician Hou Li'an: The purification rate of air purification technology of "five in one" is as high as nearly 100%

Hou Li'an, an academician of the Chinese Academy of Engineering, the first batch of experts and members of the review committee of China Science and Technology Think Tank, and an expert on environmental engineering. He is currently the director of the Institute of Rocket Army Logistics Science and Technology Research Institute.

Hou Lian has long been committed to scientific research, engineering design and technical management in the field of environmental engineering. In terms of drinking water safety guarantee, decentralized daily sewage treatment, and the purification of the environmental air purification, it has taken the lead in proposing and successfully developing independent intellectual property rights Water treatment and air purification technology and series of equipment have achieved a number of breakthrough results and creative achievements. A variety of anti -epidemic "artifacts" have been developed, which has made important contributions in environmental safety guarantee.

R & D air purification technology to help epidemic prevention and control

The main ways of transmission of new coronary virus include contact dissemination, droplet transmission, and closed space air -solid solidarity. The latter two propagation methods use air as a medium. In order to solve the problem of air pollution in the epidemic ward and protect the medical staff from infection, Hou Lian led the team to propose a solution to the hospital air quality guarantee solution to the hospitals that responded to different epidemic prevention needs, and provided validity for the full time to achieve the full time of the pathogenic microorganisms in the hospital in the epidemic area. Technical Support. He led the scientific research team to carry out the emergency research of air purification and anti -killing technology in the ward, developing a fresh air system -indoor purification -indoor disinfection -environmental function material -the full process of the exhaust system "five -in -one" air purification technology- "cloud The sterile air purifier "and put it into the anti -epidemic line.

Hou Lian said that the "cloud -style sterile air purifier", as an air purification equipment that settled in the new crown pneumonia's ward in a special period, rationally integrated and integrated a number of technologies to ensure that the pathogen was completely active with dual elimination technology. The purifier does not require filter materials, and the purification accuracy is high. It can remove fine particles such as dust, PM1, PM2.5, and droplets in the air, thereby achieving the purpose of purifying the air, blocking the virus and bacteria in the ward. He said that the purification rate of the "five -in -one" system can reach 99.9996%of the gas -soluble gum, and the use of this technology can transform ordinary offices, conference rooms, and residences into negative pressure wards.

Not only that, Hou Li'an led the team to participate in the preparation of the "Guidelines for the Operation of Environmental Protection and Environmental Protection and Environmental Security During the Prevention and Epidemic Prevention of Office, Residence and Housing and Medical Environment. During this period, indoor air safety guarantee and civil building epidemic prevention and control have important guiding significance.

Hou Lian also suggested that in the process of gradual resumption of work in various places, strengthen indoor air pollution and communication blocking work; isolation of designated hospitals and suspected cases, as well as densely populated old communities, commercial buildings and schools to carry out building air pollution and dissemination of building air pollution and dissemination Risk assessment; strengthen public environment and health education, and carry out epidemic notifications and education through the Internet and media to improve the public's environment and health literacy; take effective engineering transformation and technical measures for buildings of different ventilation types to prevent new coronary viruses from being indoors indoor air. Drial.

Strengthen scientific and technological support and improve the rural living environment

At present, the state attaches great importance to the improvement of rural living environment. In January 2019, 18 departments including the Central Agriculture Office and the Ministry of Agriculture and Rural Affairs issued the "Rural Human Resources Environmental Rectification Village Cleaning Action Plan" to solve the problem of "dirty mess" in the village environment. Hou Lian said that the overall quality improvement of the rural living environment is a complex project, which is not only related to the investment in regional infrastructure funds, but also affected by factors such as local residents' living habits, regional geographical environment, and resident cultural level. He said that the current coverage of rural domestic sewage treatment is low; the technology of domestic waste disposal technology needs to be improved; the level of sanitation construction in rural toilets is uneven; excessive application of chemical fertilizers and pesticides, and agricultural activities such as livestock and poultry breeding wastewater discharge. Natural water bodies produce water bodies nutrition; as well as long -term supervision and operating mechanism construction lag.

To this end, he suggested that scientific investigations should be conducted, the main problems of the rural human settlement environment are accurately identified, and the influence of pollution sources, terrain factors, and resident customs on the rural living environment; adhere to government guidance, formulate rectification plans according to local conditions, and avoid "" The situation of Qiancun's strategy appears; strengthens scientific and technological support, accelerates the research of rapid contamination monitoring equipment and data transmission technology, and enhances the management and supervision capabilities of the rural living environment.

Create a comprehensive research platform to prevent new pollutants

In recent years, new pollutants such as micro -plastic, endocrine interference, drugs and personal care have been frequently detected in water body, which has brought new challenges to the safety guarantee of drinking water. Hou Lian said that the water environment is the main carrier of new pollutants, and more than 90%of new pollutants will enter natural water bodies. The exposure path of new pollutants is complicated, and people's understanding of its environmental ecology and health toxicity is inconsistent, resulting in the low efficiency of the existing new pollutants' disposal schemes and treatment technology. He emphasized that "in the face of new challenges and new prevention and control needs, we should carry out a series of basic theories and key technologies to effectively prevent the environment and health risks of the new pollutant's environment and health risks."

In this regard, Hou Lian put forward four major suggestions, namely the evaluation system of impacting the impact of new pollutants on the safety of drinking water; accelerating the construction of an emerging pollutant environment and health risk assessment platform; strengthening the intelligent monitoring of emerging pollutants in the drinking water supply system; and Develop green and efficient emerging pollutant control technology and equipment. He emphasized that the "new pollutant prevention and control" key special projects should be established in the national science and technology plan, creating a comprehensive research platform, and realizing scientific research and engineering data sharing.
