Water braking aeration carrier circulation fluidized bed sewage treatment device

Abstract

The invention discloses a water braking aeration carrier circulation fluidized bed sewage treatment device, which structurally comprises a water inlet pipeline, a sludge cavity, a first processing cavity, a gas inlet opening, a circulation fluidized bed device and a water discharge pipeline, wherein the sewage drives an impeller to rotate, so that a cam repeatedly extrudes an air tube to generatepressure difference; the air pushes open a piston block shrinkage opening to realize the pressurization entering into an air guide plate; then, the airflow is fast sprayed into a carrier cavity from aspray head by using a pressurization cavity; the flowing of an inside carrier is pushed; the oxygen content is increased; the carrier activity is improved; next, a stop block is used for changing theairflow tracks; the rotational flow is generated; the pressurization and speed acceleration are realized through a force storage mold flap; the spraying out from a far aeration plate is ensured; theflow mixing and oxygenization are realized; meanwhile, the carrier cavity is separated into a special structure with an upper part and a lower part by the gas guide plate, so that the sewage can pushthe carrier; the carrier at the left upper corner inside the carrier cavity and the carrier at the right lower corner realize the staggered circulation use, so that the carrier activity is improved; the degradation on organic matters is promoted.

Description

technical field [0001] The invention relates to the field of sewage treatment, more precisely, it relates to a water brake aeration carrier circulating fluidized bed sewage treatment device. Background technique [0002] With the development of industry, the impact of industrial wastewater on environmental pollution has been deepening, making the treatment of sewage increasingly important. At present, most of the sewage is purified so that it can be recycled, and the organic matter in the sewage is filled in the flow. The carrier inside the chemical bed is adsorbed and degraded. The existing traditional technology is not comprehensive, and has the following disadvantages: [0003] Since the water flow continuously passes through the fluidized bed from bottom to top, the carrier is continuously used to purify the sewage, and the carrier does not have free time to repair itself and improve the activity. Excessive use makes the activity of the carrier continue to decrease and i...

Problems solved by technology

[0003] Since the water flow continuously passes through the fluidized bed from bottom to top, the carrier is continuously used to purify the sewage, and the carrier does not have free time to repair itself and improve the activity. Excessive use makes the activity of the carrier continue to decrease and is constantly being used. Consumption, which greatly reduces the service life of the fluidized bed, and at the same time, due to the need to provide sufficient airflow to assist the flow of the carrier inside the fluidized bed and promote the degradation of organic matter, more energy needs to be wasted, and the cost of sewage treatment is increased, and the flow of the airflow Insufficient uniformity, resulting in insufficient mixing between carriers, reducing processing efficiency
