Research of Civil Air Defense Projects Biogas Purification Independent Drainage System

The traditional drainage system of civil air defense projects is designed to discharge waste water directly to engineering external, depending on the external facilities of the project seriously, result in poor survival of the entire civil air defense in wartime. Through the engineering biogas tanks sewage treatment technology in underground engineering, independence of internal drainage system is greatly enhanced, the whole project’ self-protection and ability to substantially is greatly strengthened in wartime, then it will not only have good environmental and economic benefits, but also have a strong military benefits.
