Description
Technical field
The utility model relates to field of environment engineering more particularly to a kind of small head uniform water distribution system facilities of normal pressure.
Background technique
In sewage disposal system, water distribution uniformity has a great impact to system treatment effect, for certain treatment process
For uniform water distribution technology be even more very important one of key technology, such as the USAB technique of anaerobism[1], aerobic aeration it is raw
Object filter tank technique.Conventional uniform water distribution technology mainly has two kinds of forms of big resistance water distribution technology and slight drag water distribution technology, usually
The big resistance water distribution technology of tubular type is due to big with water pressure, and the jamproof stability of water distribution is good, but energy consumption is high.Water small for normal pressure
Head matches water problems, never more satisfactory solution.
Weir flow water distribution technology is a kind of small head water distribution technology of normal pressure, and identical crest of weir specification and weir bottom absolute altitude are on identical weir
The uniformity of water distribution can be realized under head effect.But weir flow water distribution technology also has limitation, the slight change to weir head
It is very sensitive, due to the factor of Open Channels hydraulic gradient, uniform water distribution is difficult to realize on the open channel of relatively long distance.
Numerous domestic correlative study at present[2]From the conservation of energy and the conservation of momentum, floods in conjunction with aperture and flow out, according to
Actual conditions impose a condition, and obtain many normal pressures uniform water distributions such as such as equal velocity method, equal in width method, depth of water method and variable orifice shot
Design method, while being made some attempts in practice in conjunction with introducing technology in engineering.But due to single engineering design uniqueness
Feature and be difficult to carry out the practical uniform water distribution measure of merit of water distribution system, cause project planner to be not easy to judge, select and
Optimization, there are no systematizations and standardization for the relevant technologies.
Currently in order to solving the problems, such as uneven water distribution, there is scholar to propose with the adjusting dress that elevation of weir crest is arranged on mill weir
It sets[3], it is high according to the artificial regulating weir of the different load of equipment, but will cause the waste of human resources in this way, improve whole process
Cost.There are also scholar using width along the distributing channel of journey gradually constriction；Using the distributing channel of reversed base slope；Each equipment uses
Different in width matches mill weir；It is appropriate to increase distributing channel roughness；Each equipment uses different size of distribution structure hole；Distributing channel uses
Centre water inlet, two-way water distribution[4-8].But process control is more complicated, some techniques also need professional to adjust at any time, no
Only higher cost and controllability is bad.
China Patent No. is 201710135637.5, and data of publication of application is that the application case of 2017.03.08 discloses water distribution
Device, the patent provides a kind of water injection rates not because of the injection well downhole flow regulator of the changes and modifications of well head pressure, and may be implemented water injection rate can
It adjusts and keeps constant current during water filling, avoiding leads to water injection rate not because of the variation of water injection pressure and borehole pressure
Stable problem.But its structure is complicated, system cost is higher, it is difficult to promote and apply.
