A continuous flow sbr sewage treatment device

Abstract

The invention discloses a continuous flow SBR sewage treatment device. The continuous flow SBR sewage treatment device comprises a box, reaction pools and a three-phase separator are arranged in the box, sludge pools are arranged at the bottom of the box, the two sides of each sludge pool are provided with sewage draining ports respectively, and a sludge floating preventing filter screen is arranged on the top of each sludge pool; a microporous aerator is arranged at the bottom of each reaction pool, wherein an air pipeline is arranged on one side of the microporous aerator, and an air blower is arranged on one side of the air pipeline; stirrers are arranged on the top of the box, a settling pool is arranged on the top of the three-phase separator, a filter is arranged at the bottom of the settling pool, a filter area is arranged at one side of the filter, and a solid-gas-liquid separating area is arranged at one side of the filter area. According to the continuous flow SBR sewage treatment device, digestive gas, digestive liquid and sludge particles are separated through the three-phase separator, the digestive gas is exhausted through exhaust holes, and the sludge particles slip into the sludge pools through a conical sludge slipping plate; by arranging the sludge floating preventing filter screens on the tops of the sludge pools, sludge floating can be avoided.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a continuous flow SBR sewage treatment device. Background technique [0002] SBR is an activated sludge sewage treatment technology that operates in an intermittent aeration mode. Different from traditional sewage treatment processes, SBR technology uses time-segmented operation instead of space-segmented operation, and unsteady biochemical reactions replace steady-state biochemical reactions. Reaction, ideal sedimentation instead of traditional dynamic sedimentation, with the development of society, all kinds of sewage are constantly produced, and the treatment of sewage has become the primary problem of people now, and the current sewage treatment equipment is installed in the reaction tank The three-phase separator realizes the treatment of sewage, but there will still be problems in the treatment of sewage. When the sludge is settling, the phenomenon of sludge floating will appear...

[0002] SBR is an activated sludge sewage treatment technology that operates in an intermittent aeration mode. Different from traditional sewage treatment processes, SBR technology uses time-segmented operation instead of space-segmented operation, and unsteady biochemical reactions replace steady-state biochemical reactions. Reaction, ideal sedimentation instead of traditional dynamic sedimentation, with the development of society, all kinds of sewage are constantly produced, and the treatment of sewage has become the primary problem of people now, and the current sewage treatment equipment is installed in the reaction tank The three-phase separator realizes the treatment of sewage, but there will still be problems in the treatment of sewage. When the sludge settles, the phenomenon of sludge floating will appear, resulting in incomplete sewage treatment.
