Embodiment 1

[0048] The container-type staged membrane bioreactor device is in the structure of a container body, which is sequentially composed of a semi-reaction zone 1, anaerobic reaction zone 2, aeration reaction zone 3, pure water zone 4-1, and pure water zone 4-2 (the other The structure is shown in Figure 1), except that the reaction zones are separated by partitions, and the pure water zone is not connected to the bottom of the anaerobic zone, but the semi-reaction zone is connected to the bottom of the aeration zone, which separates and defines each functional zone. effect.

[0049] The water inlet system is composed of filler 5, water inlet pump 7, mixer 10, vent valve 14-1, flow meter 19 and water inlet valve 21. The water inlet is sucked by the water inlet pump 7 located on the side of the half-reaction area to the half-reaction area 1; the water inlet valve 21 is connected to the water inlet pump 7 through the flow meter 19 to control the flow rate; the filler 5 is located in ...

Embodiment 2

[0058] The container-type staged membrane bioreactor device is in the structure of a container body, which is composed of a semi-reaction zone 1, anaerobic reaction zone 2, and aerated reaction zone 3 in sequence (the structure is shown in Figure 1). The separator is separated, and the half reaction zone is connected with the bottom of the aeration zone.

[0059] The water inlet system is composed of filler 5, water inlet pump 7, mixer 10, vent valve 14-1, flow meter 19 and water inlet valve 21. The water inlet is sucked by the water inlet pump 7 located on the side of the half-reaction area to the half-reaction area 1; the water inlet valve 21 is connected to the water inlet pump 7 through the flow meter 19 to control the flow rate; the filler 5 is located in the semi-reaction zone 1, with a ring arrangement as the main body, and is mainly used to strengthen the denitrification and hydrolysis functions of the semi-reaction zone The mixer 10 is located at the top of the semi-r...

Embodiment 3

[0068] The container-type staged membrane bioreactor device is a container body structure, which is composed of a flocculation tank 1, a sedimentation tank 2, a reaction tank 3, a pure water area 4-1, and a pure water area 4-2 (the structure is shown in Figure 1 Shown), each reaction area is separated by a partition, the pure water area is not connected to the bottom of other areas, and it has the function of separating and defining each functional area.

[0069] The water inlet system is composed of water inlet pump 7, mixer 10, dosing port 13-1, vent valve 14-1, flow meter 19 and water inlet valve 21. In the flocculation tank 1; the water inlet valve 21 is connected to the water inlet pump 7 through the flow meter 19 to control the flow rate; at the same time, the dosing port 13-1 is enabled to add the flocculation agent, and the mixer 10 is located at the top of the half reaction zone 1 to promote the flow of the agent. Dissolving and flocculation net capture; if maintenanc...

Abstract

The invention relates to a staged membrane bioreactor device, for treating sewage or micro-polluted source water, with a water container, pertaining to the environmental protection technology field. The device consists of a half-reaction zone, an anaerobic reaction zone, an aeration reaction zone and a pure water zone. The half-reaction is communicated with the bottom of the aeration zone, the bottom of the half-reaction is provided with an empty valve, one side of the half-reaction zone has a water inlet pump, the inside of the half-reaction has an internal ring filled with stuff, and the top of the half-reaction is provided with a stirrer, and the effluent of the half-reaction automatically flows into the anaerobic reaction zone. The top of the anaerobic reaction zone is provided with a stirrer, the bottom thereof is provided with a sludge empty valve, and a sludge empty device is shaped like a horn mouth and positioned in the anaerobic reaction zone, and the top of the anaerobic reaction zone is provided with a drug feeding mouth. The bottom of the aeration reaction zone has an internal return pump, the lower part of the aeration reaction zone is provided with an aeration pipe with an air inlet positioned at one side of the aeration reaction zone, and a fan is connected to the aeration pipe through the air inlet; the top of the aeration reaction zone is provided with an overflow pipe, the bottom of the aeration reaction zone is provided with an empty valve, while the middle is provided with a membrane component. The pure water zone is divided into two units, and the inside of each unit is provided with an effluent valve. The invention has the advantages of good effluent quality, multi purposes, small land occupancy, flexible and convenient using method, and is applied to the treatment of domestic sewage and micro-polluted source water, and can widen and facilitate the application of membrane bioreactor water treatment and water resource reutilization technique.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a container-type staged membrane bioreactor device for treating sewage or slightly polluted raw water. Background technique [0002] The membrane bioreactor (MBR, membrane bioreactor) formed by the combination of membrane separation technology and activated sludge technology has the characteristics of good effluent quality and small footprint, and has very attractive potential in the sewage reuse process. It is considered It is one of the most promising processes for the treatment of water resources in the 21st century. [0003] The biological unit of the membrane bioreactor mostly adopts the activated sludge method, and the membrane treatment unit used mostly uses microfiltration or ultrafiltration membranes made of organic or inorganic materials. Its main feature is to use the characteristics of membrane separation to separate excellent effluent fr...
