Embodiment Construction
[0019] The B-circulating fluidized bed aerobic system of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] Such as figure 1 Shown, the B-circulating fluidized bed aerobic system of the present invention is vertical structure, and it comprises successively connected anaerobic reaction zone 1, anoxic reaction zone 3, aerobic reaction zone 4, precipitation zone 7, anaerobic reaction zone Zone 1 is located below the system and is set in the form of a folded plate. The anaerobic reaction zone 1 is connected to the water inlet pipe 13. The anoxic reaction zone 3 and the aerobic reaction zone 4 are located above the anaerobic reaction zone 1 and communicate with each other. The top of the oxygen reaction zone 1 is fixedly installed with a lift pump 2 through a guide rod 10, and the lift pump 2 transports the waste water into the anoxic reaction zone 3, and the aerobic reaction zone 4 is located above the anoxic reaction zone...

The invention discloses a B-circulating fluidized bed aerobic system. The aerobic system is a vertical type structure, and comprises an anaerobic reaction region, a hypoxic reaction region, an aerobic reaction region and a settling region which are connected in sequence, wherein the anaerobic reaction region is positioned below the system; the hypoxic reaction region region and the aerobic reaction region are positioned above the anaerobic reaction region, and are communicated and circulated with each other; and the settling region is positioned at the side of the anaerobic reaction region and is communicated with a water outlet of the aerobic reaction region. The aerobic system disclosed by the invention adopts an integrated design, and realizes that the whole set of equipment is movable, flexible and various in application; and different treatment processes are adopted for different kinds of wastewater, so that efficient and stable denitrification and phosphorous removal needs of wastewater are met.
Description
technical field [0001] The invention relates to waste water treatment equipment, in particular to a B-circulating fluidized bed aerobic system capable of realizing integrated waste water aerobic treatment, nitrogen and phosphorus removal. Background technique [0002] With the development of society, people have higher and higher requirements for environmental protection, but at present, the discharge points of domestic wastewater in cities and towns are scattered, there are no perfect collection facilities, and the treatment rate is not high. There are still many cities and towns in my country that fail to treat domestic wastewater and discharge it directly Into rivers and lakes and other water bodies, causing greater pollution to the environment. Since the water quality of urban sewage fluctuates greatly, contains a certain amount of nitrogen and phosphorus, and has strong biochemical properties, the integrated wastewater treatment equipment is especially used for this kind...
