Description
Technical field
A kind of sewage plant tail water offshore discharge device with tide linkage is the utility model is related to, is kept away more particularly to one kind
It is near with the counter tail water that increases lake pollution thing load to lake waters near estuary of filling of eagre to exempt from tail water pollutant
Extra large tapping equipment, belongs to field of environment protection.
Background technology
At present, major part sewage treatment plant tail water in domestic coastal city uses offshore discharge mode, although tail water water quality reaches
To discharging standards, but coastal waters hydrodynamic force is weaker, and long-term continuous discharge has a great influence Offshore Waters.For lake of bordering on the sea,
Since tail water continuously discharges, at the incoming tide, tail pollutant in water can be filled to lake with tidewater is counter, increased lake pollution material and born
Lotus, in addition lake waters more close, water flowing is poor, renewal period of water body length, water body in lake self-purification capacity is poor, therefore tail water
Discharge can have a negative impact Water Environment In Lakes and Ecology.
To avoid a series of environmental problems that tail water offshore discharge is brought, Some Domestic coastal cities are required to sewage plant tail
Water carries out deep sea emission.But deep sea emission pipeline and structures difficulty of construction are larger, discharge tube often gos deep into seashore line number public affairs
In, pipeline is longer, and engineering investment cost and sewage plant operational management cost are higher.
Above two Tail water reuse mode respectively has feature, at home and abroad there is many Engineering Projects, specific to engineer application,
The selection of port area sewage plant Tail water reuse mode should take into full account the feasibility of technology, and economic reasonability, tail water is to discharging water
The many factors such as body ecology and environment influence.
Utility model content
The purpose of this utility model is to provide a kind of sewage plant tail water offshore discharge device with tide linkage, can mitigate
Because sewage plant Tail water reuse and caused by offshore waters and lake pollution thing load increase.
In order to achieve the above object, the technical solution of the utility model is as follows：A kind of sewage plant tail water with tide linkage
Offshore discharge device, it is characterised in that the device includes
Tail water cache pool, the tail water cache pool are connected with sewage plant Tail water reuse mouth, for interim storage sewage factory and office
Rear tail water up to standard is managed, sets Tail water reuse to pump in tail water cache pool；
Liminmeter, the row of being arranged on Haikou, for measuring tidal level change；
Control system, the control system receive the measurement result of liminmeter, and if flood tide state, then Tail water reuse pumps
It is stopped, if ebb tide state, then control system control Tail water reuse pump is discharged.
Further, when the storage volume V of tail water cache pool should be not less than single duration of flood tide T and cache pool emptying
Between the unit of total Tail water reuse amount V1, wherein V and V1 in T1 be m3, the unit of T and T1 are h.
Further, cache pool emptying time T1 (h) should be less than single duration of flood tide T（h）, but be no less than
（h）, i.e., should meet≤ T1≤T, the discharge capacity Q1 of Tail water reuse pump（m3/h）Should meet Q1 >=, and frequency conversion should be used
Control.
Further, tidal level is calculated as 2 sets of tidal level measuring instruments at the row of being arranged on Haikou, and 1 is standby with 1, becomes for measuring tidal level
Change.
Further, tidal level measuring instrument carries out data communication using wireless communication mode and sewage plant.
Further, tidal level measuring instrument is powered using solar panels, wind-power electricity generation associating power supply system, electric power system
It is made of solar panels, wind power generation plant, power-supply controller of electric, storage battery.
Further, the chlorination contact tank and regeneration pond of tail water cache pool and sewage plant are built jointly.
The Tail water reuse of the utility model links with receiving ocean tidal level, and at the incoming tide, sewage plant is handled in Tail water reuse marine site
Tail water after up to standard initially enters tail water cache pool in factory and caches, after tidal level measuring instrument measures ebb tide, using wireless telecommunications side
Formula and factory's controlling system progress data communication, start cache pool internal drainage pump, tail water are discharged, so as to avoid in tail water
Pollutant increases lake pollution thing load with counter fill to lake waters near estuary of eagre, while tail water is according to tide
Rule intermittent discharge, can reduce influence of the tail water to greater coasting area water quality.The application of this Tail water reuse method has obvious
Social benefit and environmental benefit.
