Several comparative process sewage treatment system: In order to select the most reliable on the craft, the investment the most economical and convenient management of urban sewage treatment system, combined with local conditions, we investigated the mature experience in wastewater treatment plants and trends, and compared. Currently, domestic and municipal sewage treatment plant processes mostly by a handle and two handle. A treatment is the use of physical methods, mainly through the grille interception, precipitation and other means to remove chunks of suspended solids in wastewater and sand and other substances. The treatment process at home and abroad are mature, very different. Secondary treatment is the use of chemical and biological methods, mainly by means of microbial life to remove waste water sports suspension, dissolved organic matter and nitrogen, phosphorus and other nutrients. Currently environmental business phone, the treatment process there are several ways Tianli environmental business phone, summed up the main representative of the conventional activated sludge process, oxidation ditch, A / O or A2 / O process, SBR and the CCAS process and so on. Currently, there are several representatives of the practical application of technology at home and abroad. Integrated wastewater treatment equipment mechanical seals: Each pump is equipped with up and down at least two mechanical seals, seal under a running water (sludge), and prevents water from entering the oil chamber, on a run in the oil chamber seal oil, stop oil into the stator chamber, under a static seal ring and ring are corrosion resistant sintered tungsten carbide, on a static seal ring and ring and corrosion-resistant graphite sintered tungsten carbide, each sealed by its own spring New pressing environmental company phone system, requires no maintenance and can automatically adjust, in the clockwise and counterclockwise rotation Taiyuan environmental company phone, did not affect the sealing function, the lack of sealing ring or in the form of compensation required pressure differential pressure is unacceptable. Note hole on the integrated wastewater treatment equipment room with a leak-proof seal oil through the filling hole oiling oiling should be able to prevent overfilling the oil chamber, leaving the oil chamber oil expansion space. Domestic use reliable seal of quality mechanical seal, ensure that the sewage sludge can not enter the oil chamber and the motor cavity.
