Description

MBR system micro-power agitating unit

Technical Field

The utility model relates to a little power agitating unit of MBR system belongs to water treatment technical field.

Background

With the rapid development of economy in China, the bearing capacity of the water environment is seriously tested, on one hand, the water resource is seriously short, and simultaneously, a large amount of sewage is generated, thereby greatly influencing the sustainable development of society and environment. Meanwhile, the water environment treatment in China also faces more and more challenges, and particularly the field of treatment of domestic sewage and black and odorous water is particularly urgent. The traditional sewage treatment equipment cannot meet the market demand due to the defects of single process, easy sludge deposition, easy damage to an anoxic system, low integration degree and the like, and the existing integrated sewage treatment equipment still needs to consider the comprehensive cost problems of process stability and later-stage technology upgrading while meeting high-standard water outlet. At present, MBR integrated sewage treatment equipment has been widely applied to various waste water treatment fields such as domestic sewage, municipal wastewater, black and odorous water, aquaculture wastewater, textile printing and dyeing wastewater as a novel and efficient sewage treatment technology. Although the integrated design can effectively combine various processes, the problems of easy damage of an anoxic system, insufficient underwater power stirring and the like exist due to the structural design.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a little power agitating unit of MBR system is provided, this agitating unit forms inside whirl through the angle that control deoxygenator intake entry and backward flow entry for the inside fluidic disturbance in anoxic zone has effectively prevented the deposit of mixing mud in the liquid, has protected the oxygen deficiency environment in anoxic zone.

For solving the technical problem, the utility model discloses the technical scheme who adopts as follows:

a micro-power stirring device of an MBR system is arranged in an anoxic zone of the MBR system; the stirring device comprises a deoxygenator, and a water inlet pipe and a return pipe which are respectively connected with the deoxygenator; the sewage to be treated tangentially enters one side of the deoxygenator through a water inlet pipe, and meanwhile, the reflux liquid in the aerobic zone of the MBR system tangentially enters the other side of the deoxygenator through a reflux pipe.

Wherein, the deoxygenator is fixed at the central position of the anoxic zone through a bracket.

Wherein, the water inlet pipe and the return pipe are arranged at the upper part of the deoxygenator, the water inlet pipe and the return pipe are arranged in the same horizontal plane, and the water inlet pipe and the return pipe are arranged vertically.

Wherein, the connecting line of the water inlet and the center of circle of the cross section corresponding to the deoxygenator is vertical to the water inlet pipe, and the connecting line of the reflux port and the center of circle of the cross section corresponding to the deoxygenator is vertical to the reflux pipe.

The water inlet and the two tangential fluid actions of the backflow port entering the deoxygenator enable the internal fluid of the deoxygenator to form micro-rotational flow to generate disturbance, so that the whole anoxic tank fluid is driven to be stirred.

Has the advantages that: the water inlet and the backflow port arranged in the device of the utility model can tangentially feed water along the deoxygenator, thereby forming rotational flow, generating disturbance to the water body and forming micro-stirring effect; in addition, a deoxygenator in the device is fixed at the central position of the MBR system through a bracket, so that the system space is fully utilized, and the hydraulic condition is optimized; finally, this device makes the MBR system carry out the even stirring of mixed liquid under unpowered operating mode, makes it obtain the intensive mixing, has effectively avoided the inhomogeneous settlement of anoxic zone mud, has maintained system stability.

FIG. 2 is a schematic diagram of the connection of the water inlet pipe and the return pipe with the deoxygenator.

Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-2, the MBR system micro-power stirring device of the present invention is disposed in the anoxic zone 6 of the MBR system; the stirring device comprises a deoxygenator 2 (deoxygenation cylinder) and a water inlet pipe 1 and a return pipe 4 which are respectively connected with the deoxygenator 2; the sewage to be treated tangentially enters one side of the deoxygenator 2 through the water inlet pipe 1, and meanwhile, the reflux liquid in the aerobic zone of the MBR system tangentially enters the other side of the deoxygenator 2 through the reflux pipe 4; the deoxygenator 2 is fixed in the center of the MBR system (anoxic zone 6) by a bracket 3. The water inlet pipe 1 is fixedly connected with an external drain pipe through a flange 5, the water inlet pipe 1 is fixedly connected with a water inlet 8 of the deoxygenator 2 through a flange, and the return pipe 4 is fixedly connected with a return port 7 of the deoxygenator 2 through a flange.

Wherein, inlet tube 1 and back flow pipe 4 all set up in deoxygenator 2 upper portion, and inlet tube 1 and back flow pipe 4 set up in same horizontal plane, and inlet tube 1 and back flow pipe 4 mutually perpendicular set up. Wherein, the connecting line of the water inlet 8 and the center of the cross section corresponding to the deoxygenator 2 is vertical to the water inlet pipe 1, and the connecting line of the reflux port 7 and the center of the cross section corresponding to the deoxygenator 2 is vertical to the reflux pipe 4.

When the system operates, the inlet water enters the deoxygenator 2 in a tangential direction, the reflux liquid also enters the deoxygenator 2 in a tangential direction, and the inlet water and the reflux liquid are converged at the upper part of the deoxygenator 2 to form a rotational flow, so that the water body is disturbed and fully stirred, and the sludge in the fluid is effectively prevented from being deposited.
