Example Embodiment

[0027] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0028] like Figures 1 to 6 shown, is the first embodiment of the present invention.

[0029] An internal circulation fluidized reaction device for sewage treatment includes a pool body 1, and two vertical partitions 2 parallel to each other are arranged in the pool body 1, and each partition 2 is connected to the pool body 1. Between the pond walls is the fluidized aerobic reaction zone 3, and between the two partitions 2 is the precipitation catchment zone 4, that is, the pond body 1 is provided with two fluidized wells located on both sides thereof respectively. Oxygen reaction zone 3 and a precipitation catchment zone 4 located in the center thereof, the separator 2 can be respectively fixed on the pond wall of the pond body 1 through its two end faces during the specific implementation, so as to be fixed in the pond body 1, as Try to u...

Abstract

The invention relates to an internal circulation fluidized bioreactor used for the sewage treatment, a pool body thereof is internally provided with a fluidized aerobic reaction zone, a settlement collecting area and an anoxic reaction zone, the bottom of the pool body is provided with an aeration device, the top part of the settlement collecting area is provided with a yielding aqueduct, the anoxic reaction zone is internally led with a water inlet pipe, the top part of the anoxic reaction zone is provided with an exhaust pipe, and the bottom of the anoxic reaction zone is provided with a water distribution pipe which communicates with the anoxic reaction zone and the fluidized aerobic reaction zone. The fluidized aerobic reaction zone is internally provided with a vertical partition board which divides the reaction zone into two zones, gaps communicated with the two zones are arranged on the partition board at intervals, and the aeration device is positioned outside the partition board. Compared with the prior art, the pool body is divided into the anoxic reaction area, the fluidized aerobic reaction zone, and the settlement collecting area, a biological reaction, a mud-water separation, and a sludge return flow systems of the sewage are combined organically, the sewage purification effect is good, the partition board divides the position of the original aerobic zone into two positions, so as to cause the aeration range to be small, the oxygen utilization ratio to be improved, and the aeration effect to be greatly increased.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an internal circulation fluidized biological reaction device for sewage treatment by using biological reactions. Background technique [0002] With the continuous shortage of water resources and the continuous strengthening of environmental pollution control, people have begun to pay attention to the treatment of various sewage and reuse it as much as possible. At present, the devices for treating urban domestic sewage can be roughly divided into activated sludge filter tanks, biological reaction filter tanks, biological contact oxidation filter towers, etc. The biological reaction filter tanks use biological fillers to fully contact sewage to produce biological reactions. , so that the sewage can be purified. Most of the current biological reaction filter tanks have defects such as large construction area, large investment, complicated operation and management, and hig...
