Long history of health as a whole septic tank 
 Septic tanks first originated in the 19th century Europe, dating back more than 100 years of history, septic tanks and sewage is flowing through the pond sediment sludge direct contact, the role of organic solids by anaerobic bacteria break down a sedimentation tank . First occurrence of septic tanks as a way to avoid clogging pipes set the cut-off manure facilities, retention, precipitation of large particles of impurities in sewage, sewage pipes to prevent clogging, reducing the pipeline depth, play an active role in protecting the environment. In China, the septic tank is an essential life supporting people living facilities, almost every building septic tanks are equipped with appropriate facilities. 
 Brick and concrete septic tanks due to the design, construction, use, management, many problems, resulting in more than 95% use septic tanks serious leakage after 1-2 years, due to not being seriously, septic tank leakage serious pollution of underground drinking water sources and the underground water supply pipes, causing more serious degree of tilt in different buildings. In addition, the traditional brick and concrete septic tank due to lack of technical content, handling poor water quality, discharge of sewage seriously overweight, has greatly increased the workload of the sewage treatment plant, municipal pipe network in the absence of a few areas of traditional septic tank treated sewage directly discharged into rivers and lakes, to the surrounding river water caused serious damage to the environment. Because the traditional low-tech septic tanks, corruption function is poor, Qingtao cycle is short, if the daily maintenance and management in place, there will be gas poisoning, explosion and other hidden dangers. 
 Developed capitalist countries in the West, septic tanks, facilities have already gone beyond the traditional sense of "septic tank" has become a sewage treatment facilities, water treatment technology has already reached the level of reuse. Our R & D Dragon Sport Series FRP fiberglass septic tanks, buried the whole environment-friendly and highly effective biological septic tank is a septic tank technology for China's current development status, combined with advanced technology and experience of Western developed countries, continue to develop in line with China's national conditions improve septic pool equipment, for China to make greater contribution to environmental protection.
