Urban sewage treatment status quo and problems: our major cities have polluted rivers, because the river mobility, changes, using the conventional method, which uses artificial and mechanical dredge the river, can not cure the problem of pollution of rivers , pollution of rivers in the world belongs to the forefront of technology. 1999 10 menstrual approved by the provincial Department of Environmental Protection, and in support of the EPA under Haikou City, on October 27 start date Datong ditch in the sea Galaxy Road area 30 meters long, 20 meters wide and 2.0 meters deep production of engineering test run on the river. The river is located in Haikou City, area, nearly 5 kilometers in length, due to the large number of urban sewage discharged into the river in a common method of wastewater treatment, water polluted, producing a large number of primary sludge, seawater back, blue algae continue to breed, smelly gas is very strong, black river, over the years the people called "drainage ditch." 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) in the oil chamber to prevent water from entering the wastewater treatment method, a seal on the oil in the oil chamber run, stop the oil into the stator chamber, under a static seal ring and ring are corrosion resistant sintered tungsten carbide dyeing wastewater treatment methods on a static seal ring and ring and corrosion-resistant graphite sintered tungsten carbide, Each group seal pressed by its own spring system, no maintenance and can automatically adjust, in the clockwise and counterclockwise rotation, 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 domestic wastewater treatment facilities in the integrated wastewater treatment room with a leak-proof seal oil oxidation, by the injection 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.
