Description

A kind of sewage plant MBR emptying overflow balance well system

Technical field

Sewage plant MBR technology fields are the utility model is related to, more particularly to traditional handicraft sewage plant transform MBR techniques as.

Background technology

Water distribution at present catchment mud-collecting well have the advantages that to save take up an area, water distribution waterpower of catchmenting it is uniform, be widely used in biography Process spent water of uniting handles engineering second pond front end.It is middle including mud-collecting well, distribution well and the sump set by interior outer set Mud-collecting well collection mud, and biochemistry pool is back to by dredge pump；Outside is distribution well, and water inlet is by distribution well even into film around Pond；Outermost is sump, and the water outlet of some second ponds is converged by sump is uniformly delivered to next processing structure.

With the development in China city and the raising of water quality requirement, to improve aquifer yield, lifting water standard, traditional work Skill sewage plant is gradually transformed into MBR（Membrane Bio-Reactor, MBR）Technique.But due to MBR techniques water inlet outlet pipe Road, sludge return pipe have changed position, original water distribution, catchment, mud-collecting well is idle.

Utility model content

The purpose of this utility model is：A kind of sewage plant MBR emptying overflow balance well system is proposed, at traditional wastewater Reason factory original water distribution mud-collecting well that catchments is transformed, and makes it have the function such as water balance, overflow, emptying.

The purpose of this utility model is realized by following technical proposals：

A kind of sewage plant MBR emptying overflow balance well system, including membrane cisterna, in addition to liquid level equilibrium well, overflow well and row Empty well, nested setting, several membrane cisternas are set on the outside of liquid level equilibrium well from outside to inside for liquid level equilibrium well, overflow well and emptying well Put and connected by liquid level equilibrium pipe with liquid level equilibrium well, each membrane cisterna is also connected by overflow pipe and membrane cisterna evacuated tube with overflow well Logical, membrane cisterna evacuated tube is provided with exhaust-valve, is connected between overflow well and emptying well by connected holes, and emptying well is provided with outer row's Exhausting pipeline.

This patent is transformed original water distribution mud-collecting well that catchments, and distribution well transform liquid level equilibrium well, sump transformation as For overflow well, mud-collecting well transform emptying well as.When membrane cisterna water level is higher, sewage can flow to overflow by membrane cisterna by overflow pipe Well, realize the function of overflow.When needing to be vented membrane cisterna, the exhaust-valve in membrane cisterna evacuated tube can be opened, allows sewage to flow to overflow Well, connected by connected holes between overflow well and emptying well, arranged finally by outside exhausting pipeline.Liquid level equilibrium is set simultaneously Pipe, surrounding membrane cisterna is connected, realize the function of water level balance by liquid level equilibrium well.

Alternatively, the overflow inlet position that overflow pipe is connected on membrane cisterna is provided with the overflow wall for surrounding overflow inlet, overflows Wall bottom surface closing top surface opening is flowed, and overflow wall apical side height is less than membrane cisterna edge.Preferably, overflow wall is highly low In membrane cisterna edge 300mm.In the program, overflow wall, overflow inlet and overflow pipe realize overflow of the membrane cisterna reclaimed water to overflow well： When membrane cisterna water level is higher, sewage can be crossed overflow wall by membrane cisterna, enter overflow by overflow inlet, overflow pipe successively Well.

Alternatively, exhausting pipeline connects with factory level ground sewage pipe.In the program, enable membrane cisterna overflow sewage and emptying sewage Enough drain into inlet pumping station.

The foregoing main scheme of the utility model and its each further selection scheme can be with independent assortments to form multiple schemes, The scheme that can be used and be claimed for the utility model；And the utility model,（Each non conflicting selection）Between selection and Can also independent assortment between other selections.Those skilled in the art are after the present invention program is understood according to prior art and public affairs Know that general knowledge can understand there are multiple combinations, be the claimed technical scheme of the utility model, do not do exhaustion herein.

The beneficial effects of the utility model：Pass through the transformation for the mud-collecting well that catchmented to water distribution, it is possible to achieve membrane cisterna emptying, membrane cisterna The function of liquid level equilibrium between overflow, membrane cisterna.Wherein each membrane cisterna liquid level equilibrium, can make biochemistry pool flow into the water of membrane cisterna Substantial equilibrium, avoid enter into membrane cisterna water inequality.

Embodiment

The utility model is further described with reference to specific embodiments and the drawings.

With reference to shown in figure 1,2, arrow flows to for sewage in figure, a kind of sewage plant MBR emptying overflow balance well system, including Membrane cisterna 11, in addition to liquid level equilibrium well 4, overflow well 5 and emptying well 6, using the distribution well of raw sewage treatment plant as liquid level equilibrium well 4, sump is overflow well 5, and mud-collecting well is emptying well 6, and well 6 is nested from outside to inside sets for liquid level equilibrium well 4, overflow well 5 and emptying Put, several membrane cisternas 11 set and connected by liquid level equilibrium pipe 3 with liquid level equilibrium well 4, each film around the outside of liquid level equilibrium well 4 Pond 11 is also connected by overflow pipe 2 and membrane cisterna evacuated tube 1 with overflow well 5, and membrane cisterna evacuated tube 1 is provided with exhaust-valve 10, overflow well 5 Connected between emptying well 6 by connected holes 8, emptying well 6 is provided with the exhausting pipeline 7 of outer row, exhausting pipeline 7 and factory's level ground sewage Pipe connects, and the overflow sewage of membrane cisterna 11 and emptying sewage is drained into inlet pumping station.The overflow that overflow pipe 2 is connected on membrane cisterna 11 enters Mouth position is provided with the overflow wall 9 for surrounding overflow inlet, the bottom surface of overflow wall 9 closing top surface opening, and the top surface of overflow wall 9 is high Degree is less than the edge of membrane cisterna 11, and the preferably height of overflow wall 9 is less than the edge 300mm of membrane cisterna 11.

When the water level of membrane cisterna 11 is higher, sewage can flow to overflow well 5 by membrane cisterna 11 by overflow pipe 2, realize overflow Function.When needing to be vented membrane cisterna 11, the exhaust-valve 10 in membrane cisterna evacuated tube 1 can be opened, allows sewage to flow to overflow well 5, overflow Connected by connected holes 8 between well 5 and emptying well 6, arranged finally by outside exhausting pipeline 7.Liquid level equilibrium pipe 3 is set simultaneously, Surrounding membrane cisterna 11 is connected by liquid level equilibrium well 4, realizes the function of water level balance.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
