Description
Technical field
The invention belongs to intake technology fields, and in particular to a kind of water quality and quantity for being close to river and riverbed radiating aperture water intaking technique
Regulating system, and using aforementioned water quality and quantity regulating system in the method for regulating water quality water.
Background technique
Riverbed river bed water is a kind of underground current water of preservation in the natural sandy cobble water-bearig layer in riverbed.It is close to river and riverbed
Diafiltration water intaking, most typical method for fetching water are Weeping well with natural filter bed water intaking and radiant tube water intaking.Be close to river radiant tube water intaking, be
Sump is constructed on riverbank, sump is communicated with the more radiant tubes protruded into riverbed sand pebble layer with diafiltration function.River
Bed radial water intaking, is mainly to include sump by building reversed water intake system under riverbed and be connected to sump
More water delivery tunnels are equipped with multiple charge for remittance chambers in water delivery tunnel, are communicated with more on charge for remittance chamber and protrude into riverbed sand pebble layer
In radiant tube.
Turbidity is an important indicator of evaluating water quality, and the turbidity standard of urban water water quality is 1NTU, in special circumstances
It is relaxed to 3NTU.The water level in middle riverbed is fluctuation throughout the year, and flood period, riverbed water level increases, water turbidity is high, is gone out in well
Water increases, water turbidity accordingly increases；In dry season, river bed water potential drop is low, water turbidity is low, water yield reduction, water quality in well
Turbidity accordingly reduces.
When dry season, the turbidity of water is low in riverbed, and after sand pebble layer natural filter, the infiltration water energy in sump is enough held
Easy reaches 1NTU or less；Flood period, the turbidity of water is high in riverbed, the infiltration after sand pebble layer natural filter, in sump
Water is hard to reach urban water 1NTU standard, or even needs to filter again and can be only achieved urban water 1NTU standard.
Summary of the invention
Present invention seek to address that the technical problems existing in the prior art, the first purpose of the invention is to provide one kind to be close to
The water quality and quantity regulating system of river and riverbed radiating aperture water intaking technique is percolated using pipeline and is fetched water to solve flood period, water quality
Difference, it is difficult to the problem of reaching urban water standard；Above-mentioned water quality and quantity tune is utilized a second object of the present invention is to provide a kind of
Section system is in the method for regulating water quality water.
In order to achieve the above first purpose, the present invention adopts the following technical scheme: being close to river and riverbed radiating aperture water intaking technique
Water quality and quantity regulating system, including sump, several protruded into sand pebble layer being directly or indirectly connected to sump
Intake pipe, intake pipe completely or partially protrude into sand pebble layer；The end of several intake pipes at the top of sand pebble layer at a distance from
All not identical or all not identical, the turbidity height fetched water in several intake pipes is not all identical or all not identical；It takes
Switch valve is equipped in water pipe.
In above-mentioned technical proposal, flood period, by closing the high intake pipe of turbidity, the water for making to collect in sump is whole
Haze reduction, water intaking water quality when so as to improve flood period, makes up to urban water standard；Turbidity is closed in flood period
High intake pipe improves water intaking water quality under the premise of meeting urban water supply to sacrifice water intaking water.Dry season is meeting
Under the premise of water turbidity, the high intake pipe of turbidity is opened, increases water intaking water, meets the needs of water-supply quantity.
Water quality and quantity regulating system of the invention, flood period, using the big characteristic of its water, in the premise for meeting water withdrawal
Under, water intaking water quality is improved by closing the high intake pipe of turbidity；Dry season leads under the premise of meeting water intaking water turbidity
It crosses and opens the high intake pipe of turbidity to improve water withdrawal；The natural characteristic that riverbed water level height variation throughout the year is utilized comes
Adjust the water quality and quantity of water intaking.
In the preferred embodiment of the present invention, for detecting water turbidity in sump is equipped in sump
One transmissometer and/or limnimeter for detecting water level in sump.
In the preferred embodiment of the present invention, the second turbidity for detecting water turbidity is provided in intake pipe
The output end of instrument, the second transmissometer is connect with long-distance monitorng device.Thus it is convenient for water factory, water supply management organization and water quality monitoring machine
Structure etc. knows that the turbidity of every intake pipe water intaking according to circumstances opens or closes intake pipe in real time.
In the preferred embodiment of the present invention, intake pipe is located at when being close to river, is directly connected to sump, is fetched water
Pipe completely or partially protrudes into sand pebble layer；Recoiling device is equipped in sump, intake pipe is equipped with and connect with recoiling device
Recoil valve；
When intake pipe is located in riverbed, sump is communicated with several water delivery tunnels, is equipped with several charges for remittance in water delivery tunnel
Chamber, intake pipe is connect with charge for remittance chamber or intake pipe is directly connected to sump；Intake pipe completely or partially protrudes into sand ovum
In rock layers；Recoiling device is equipped in sump, charge for remittance chamber, intake pipe is equipped with the recoil valve connecting with recoiling device.
It is located at different positions according to intake pipe, for example is close in river or riverbed, the connection type of intake pipe and sump is not
Together.Dry season, fetch water water shortage when, open recoil valve while turn off the switch valve, by intake pipe to intake pipe periphery
Sand pebble layer is backwashed, its chocking-up degree is reduced, to increase water withdrawal.
In the preferred embodiment of the present invention, recoil valve is located at one end that intake pipe is connect with sump, or anti-
Rush that valve is located at one end that intake pipe is connect with charge for remittance chamber or recoil valve is located at the beginning that intake pipe protrudes into sand pebble layer.Thus
Tamper in the sand pebble layer of intake pipe periphery is backwashed, is rinsed comprehensive.
In the preferred embodiment of the present invention, switch valve is located at the beginning that intake pipe protrudes into sand pebble layer.Thus
After turning off the switch valve, the river bed water in sand pebble layer not can enter in intake pipe, when improving flood period, water of fetching water in sump
Matter.
It further include the controller being connect with long-distance monitorng device in another preferred embodiment of the invention,
