Biochemical organic matter and can be by the suspended solid of activated sludge absorption and some other material, while can also remove a part of phosphorus
Element and nitrogen, it is the general designation of the various methods for the microorganism (micro-organism) that biological wastewater treatment is suspended in water.
Typical activated sludge process is made up of aeration tank, sedimentation basin, sludge recirculation system and excess sludge removal system.
Sewage and the activated sludge of backflow enter aeration tank and form mixed liquor together.The compressed air sent from air compressor station, lead to
The air-diffuser for being laid on aeration tank bottom is crossed, is entered in the form of tiny bubble in sewage, it is therefore an objective to increase in sewage
Dissolved oxygen content, mixed liquor is in the state of vigorous agitation, in suspended state.Dissolved oxygen, activated sludge and sewage are mutual
Mix, fully contact, activated sludge reaction is normally carried out.
In practice, it has been found that pollutant is transferred to efficiency that sludge gets on quickly, and metabolic rate is slower.Handle city
During city's sewage, waste water BOD was just often reduced by 90% or so less than 1 hour.But if these sludge refluxes to aeration tank,
But such ability can not be reproduced.The key for solving this problem has been found by long-term research people, if it is possible to carry
The aeration efficiency of high aeration tank, the metabolic rate of activated sludge can significantly improve, and can avoid this phenomenon naturally.
However, current biochemical oxidation system aeration uses the modes such as aeration plate, aeration tube, boring aeration, arrangement
Arrange that oxygen transmission efficiency is up to 20% for bottom of pond.In order to ensure the activity of sludge in aeration tank, it is necessary to significantly improve and expose
Tolerance, the waste of oxygen of air supplies and substantial amounts of energy loss are caused, and need substantial amounts of aerator to carry out air
Supply distribution.
