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 structured as figure 1 As shown), except that the reaction zones are separated by partitions, 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 has the function of separating and defining each functional zone.

[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 loca...

Embodiment 2

[0058] The container-type staged membrane bioreactor device is a container body structure, which is composed of a half reaction zone 1, anaerobic reaction zone 2, and aerated reaction zone 3 (its structure is as follows: figure 1 shown), the reaction zones are separated by partitions, and the half-reaction zone is connected to 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 s...

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 (its structure is as follows: figure 1 As shown), each reaction zone is separated by a partition, and the pure water zone is not connected to the bottom of other zones, which has the function of separating and defining each functional zone.

[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 m...

Abstract

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. It is composed of half reaction area, anaerobic reaction area, aeration reaction area, and pure water area. The half reaction area is connected to the bottom of the aeration area. There is a vent valve at the bottom of the half reaction area, a water inlet pump on one side, and fillers in the inner ring. , there is a mixer on the top, and the water from the semi-reaction zone flows into the anaerobic zone; there is a mixer on the top of the anaerobic reaction zone, and a sludge discharge valve at the bottom. Drug port; there is an internal return pump at the bottom of the aeration reaction area, and an aeration pipe is installed below, and the air inlet of the aeration pipe is located on the side of the aeration reaction area. There is a vent valve at the bottom and a membrane module in the middle; the pure water area is divided into two units, and each unit is equipped with a water outlet valve. The invention has the advantages of good effluent quality, multi-function, small occupied area and flexible and convenient use. It is suitable for the treatment of domestic sewage, slightly polluted raw water, etc., making the application of membrane bioreactor water treatment and water resource technology more extensive and convenient.

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...
