Description
Technical field
The present invention relates to a kind of water distribution systems of sewage treatment field, in particular, being related to a kind of pulse strength and stringing
The regulatable water distribution system of mode.
Background technique
Sewage Biological Treatment is that the general name of sewage is handled with biological method, is widest in Modern sewage processing application
Dirty Organic substance in water is mainly converted into simple inorganic matter by the decomposition of microorganism, obtains sewage by one of method
Purification.For biological wastewater treatment process, either anaerobic biological treatment or Aerobic biological process system all have
There is scale big, the features such as long flow path, link is more, and subsystem is more, and integration of equipments degree is high.A certain subsystem or local facility go out
Existing problem, usually leads one and dynamic whole body, influences the normal operation of entire processing system.In existing biologic process for treating sewage and
In system equipment operation, pulse water distribution system, which belongs to, to be less susceptible to draw attention, but is easy to the subsystem to go wrong.
Pulse water distribution system is extensive in Sewage Biological Treatment industrial application, principle be by siphon pipe water from upper
Lower flowing takes siphon inner air tube away and generates vacuum, using siphon pipe inside and outside differential pressure as the power of water distribution system, to realize
Water distribution function.However, at present there is following two aspect in the technical equipment in practice:
First is that pulse strength is relatively fixed, can not normality adjust, be difficult and microorganism be strong to water distribution in not same order growth section
The difference requirements of degree are synchronised.This is because conventional water distribution system liquid gross weight during forming siphon and siphon destructive
It measures relatively fixed, causes each water distribution pulse strength almost without too big difference.Pulse strength is excessive to easily lead to activated sludge
It is lost, pulse strength is too small, leads to biochemical reaction inefficiency again.If water distribution system pulse strength can not normality adjust,
It is easy to appear the excessive or too small extreme case of pulse strength, to cause entire processing system unstable and inefficiency.
Second is that existing water distribution system is to set perforation water distributor in biochemical bottom of pond portion, be easy to appear a kind of situation in this way, i.e., it is long
After phase operation, often leads to water distribution blockage and be difficult to overhaul.Pulse water distribution system is generally positioned at anaerobic reactor top, and
Water distributor is then densely arranged in anaerobic reactor bottom, i.e., is protruded into anaerobic reactor pond by water distribution supervisor and adopted in bottom of pond
With perforation water distribution, once water distribution blockage, it is necessary to temporary downtimes, emptying anaerobic reactor carry out system equipment overhaul.Inspection
It adds strain debugging after the completion of repairing again again, has thus elongated the time cycle, reduce the operation effect of entire processing system
Rate.
To solve the above-mentioned problems, overcome prior art drawback, the present invention provides a kind of pulse strength and piping mode is equal
Regulatable water distribution system.
Summary of the invention
The present invention exactly be directed to existing water distribution system during practice existing drawbacks described above and design, especially
The Sewage Biological Treatment big suitable for variation water quality range, suspension content is high.
In order to achieve the above objectives, the present invention adopts the following technical scheme that: a kind of pulse strength and piping mode are adjustable

It is internal that tracheae (3) is mounted on water tank (4)；Central siphon pipe (1) upper end is located at bell jar (2) inside, and lower end is located at water seal arrangement
(8) internal；Water distributing pore (1-1) is arranged in central siphon pipe (1) lower end；Water distribution is responsible for (5) setting on the outside of the cloth water tank (4) and to edge
Horizontal direction extends outwardly, and water distribution branch pipe (7) upper end is vertically connected with water distribution supervisor (5), and the other end extends to biochemical reactor
(6) bottom；Auxiliary siphon tube (15) two sides are separately connected bell jar (2) and ejector (14)；Ejector (14) is intake by jet stream
(13) connection sewage water inlet pipe (11) is managed, it is internal that jet stream outlet pipe (12) extends to water tank (4).
The beneficial effect designed in this way is:
(1) negative pressure in the air velocity for adjusting valve regulation ejector suction inlet and then the central siphon pipe of adjusting is utilized
Degree, to realize adjusting and control the purpose in burst length and intensity.
(2) water-distributing device setting carries out multipoint water feeding by water distribution branch pipe on biochemical reactor top, can want for operation
It asks and high intensity pulses is carried out to any region in reactor, avoid dead angle siltation sludge, water distributor is not limited to anaerobic reactor
Bottom, but flexibly and easily arrange.
(3) water distribution branch pipe and water distribution supervisor can use union or flanged joint, need to only tear pipeline section that band overhauls open when maintenance
It opens and leaves the water, without waste water in blow-down pit；When replacing any independent water distribution branch pipe, biochemical reactor normal operation is not influenced,
Maintenance and Repair are very convenient.
The working method and process of water distribution system of the present invention are designed such that
(1) the water distribution preparation stage: when water enters water tank (4) from sewage water inlet pipe (11) with certain pressure, largely
Water enters water tank (4), and a small amount of water passes through ejector (14) along water inlet pipe (13) with higher flow velocity and takes bell jar (2) away
Air between central siphon pipe (1), gradually generates negative pressure, not yet starts in this process water distribution, and water tank (4) liquid level is not
It is disconnected to rise.
(2) water distribution stage of development: when negative pressure reaches critical point in central siphon pipe, external atmosphere pressure is by water tank (4)
Interior instant water squeezes into central siphon pipe (1), after water distributing pore (1-1), water distribution supervisor (5), water distribution branch pipe (7) evenly distribute,
Water is squeezed into rapidly and forms stirring in anaerobic reactor (6), water tank (4) liquid level constantly declines in this process.
(3) water distribution stop phase: when liquid level is reduced to siphon destructive mouth (2-1), air enters central siphon pipe (1) and makes
Inside and outside differential pressure is identical, and siphonic process is caused to be destroyed, and water tank (4) liquid level stops decline.So far, a complete water distribution period
Terminate, and initially enters next water distribution period, iterative cycles.
In short, the present invention passes through above structure and working method, the optimization design of process, existing water distribution system is overcome
Various drawbacks realize the regulatable purpose of pulse strength and piping mode.
