Интегральная Похоронен очистки сточных вод Оборудование

I. Summery With the increase of the economy and population, the human beings have paid more attention on the pollution of nature. On the basis of summarizing the operation of the sewage device and combined with our scientific research achievement and the artificial practice of our company, a set of treatment device for organic waste water has been designed and it has the sewage treatment device adopted the domestic advanced process and production manufacturing technology at the late period of 90s with the fiber glass and stainless steel as the main materials. The purpose is to make the domestic sewage and industrial waste water reach the requirements of the user discharge or recycle by means of the equipment. II.Application of the buried sewage treatment device 1. Hotel, restraint, sanatorium and hospital. 2. Residence community, village and town. 3. Station, air port, sea port wharf and ship. 4. Factory, mine, military, tourist side and scenic spot. 5. Various industrial sewage similar to the domestic sewage. III.
