Description
Technical field
The present invention relates to a kind of underflow type Vatch basin that combined closure system is controllable and its amount control methods that shuts off, and belong to Municipal
Pumping equipment technical field.
Background technique
Vatch basin is the important structures in one of municipal drainage system, collects dry days in line sewage, and the abatement rainy day overflows
Stream pollution.When dry days, the sewage of discharge outlet along the river is shut off into sewage treatment plant；When the rainy day, part rain dirt mixed flow water is cut
Stream enters sewage treatment plant, and the rain dirt mixed flow water more than the ability of shutting off is discharged into surface water body.
Traditional Vatch basin has slot type, the weir weir Shi Hecao convolution, has the disadvantage that 1. design combined closure systems and objective need
The combined closure system difference asked is larger.Design combined closure system is that it is high to set different overflow weirs by centainly investigating and theoretical calculation
The measures such as degree determine；The combined closure system of objective demand is dirty according to the actual conditions of each row mouthful interflow mixed flow and overflow
What the ability of dye control requirement and urban sewage treatment system determined.The error of the two is very big, and height of weir plate is once setting
It is difficult to adjust.2. water drainage blocks water.Design discipline requires overflow weir to rise higher than river flood position to prevent river water from flowing backward, this is bound to
It is unsmooth to form water drainage.3. low efficiency of shutting off.It has usually been connected several Vatch basins by the main pipe that shuts off in drainage system, upper one
A well shut off after water shut off with next well before water mix after shut off again, mixed flow water is diluted step by step, eventually enters into sewage
The water concentration of system is low.4. depositing seriously polluted.What is shut off is mostly surface layer water body, and pipe, well deposition are seriously polluted, finally with heavy rain
It washes away one and is incorporated to river, influence Urban Water Environment.
In recent years, Vatch basin technology is developed, and is mainly included the gate valve substitution fixed weir by power manipulation, is realized
Combined closure system is adjustable；There is the automated system according to the information such as rainfall, river water level control gate valve aperture；Reliable buoyancy control
Complicated transmission device of gate valve aperture, etc..These new technologies realize the controllable of combined closure system, but using complicated electromechanical equipment
And automatic control equipment, necessity is not strong, and high failure rate, investment is big, O&M cost is high.In addition, the water concentration that shuts off is low, water drainage blocks water
Etc. situations still have.
Summary of the invention
The present invention is for combined closure system of the existing technology is difficult to control, the water concentration that shuts off is low, water drainage blocks water, river water falls
It fills, complex structure and other problems, the control method of a kind of Vatch basin and its combined closure system is provided, can effectively improve and cut a dirty efficiency, adaptation
Interception ratio, fair current are freely arranged, reflux check, no mechanical equipment, and high reliablity is with low investment, and O&M cost is low, are suitble to Chinese city
Status Quo of Infrastructures and demand for development.
In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is that providing a kind of underflow type that combined closure system is controllable
Vatch basin, including well body, well lid and mixed flow tube, the structure of Vatch basin are as follows: mixed flow tube passes through the two sides of well body, and one end is entrance,
The other end is outlet；The middle section bottom of mixed flow tube is provided with notch in well, the outlet for the main pipe that shuts off is entered for mixed flow sewage, in well
Pipeline leakage plugging device is socketed on mixed flow tube, the internal diameter of the pipeline leakage plugging device is identical as mixed flow pipe outside diameter, and length is greater than mixed flow tube undercut；Axis
To mobile pipeline leakage plugging device, change the relative position of pipeline leakage plugging device and notch, for adjusting the flow of mixed flow outlet of sewer.
In technical solution of the present invention, the bottom of well body is equipped with chute, the shaped upper part of chute arc low between the senior middle school of both sides
Shape, the main pipe that shuts off are set among chute.The outlet end of the mixed flow tube is oblique section, and flap valve is mounted on the outlet end of mixed flow tube.
Technical solution of the present invention also provides a kind of amount control method that shuts off of Vatch basin, includes the following steps:
(1) mixed flow tube is passed through to the two sides of well body, one end is entrance, and the other end is outlet；The middle section bottom of mixed flow tube is opened in well
There is notch, the outlet for the main pipe that shuts off is entered for mixed flow sewage, is socketed pipeline leakage plugging device, the internal diameter of the pipeline leakage plugging device on mixed flow tube in well
Identical as mixed flow pipe outside diameter, length is greater than mixed flow tube undercut；
(2) ability according to pollution load of overflow control necessary requirement and urban sewage treatment system, determines total interception ratio；
(3) the sewage quantity measuring and calculating according to each Vatch basin institute coverage and total interception ratio, calculate the design of single Vatch basin
Combined closure system；
(4) the practical combined closure system that Vatch basin is determined using hydraulic test method, establishes practical combined closure system and pipeline leakage plugging device relative position
Relationship, the axial position of initial setting Vatch basin pipeline leakage plugging device；
(5) after Vatch basin comes into operation, according to running situation of actually shutting off, then axially adjustable pipeline leakage plugging device position, change mixed
The discharge area of flow tube lower cut meets requirement of shutting off.
Compared with prior art, the beneficial effects of the present invention are: pass through adjust pipeline leakage plugging device relative position it is adjustable real
The size of border combined closure system, effective amendment design error, makes it more meet objective requirement, under conditions of sewage treatment capacity is certain
Utmostly control pollution load of overflow；It eliminates because of the resistance that drains flooded fields caused by shutting off；Underflow type mixed flow tube lower cut can reach higher
Concentration of shutting off；It solves the problems, such as to dilute step by step；It is unobstructed that flap valve design can be realized draining, and prevents river water from flowing backward；
No equipment design means higher reliability, the investment more saved and less O&M cost.
