Description

Desliming system waste water surplus flocculant regenerates and recycling device
Technical field
It the utility model is related to water treatment facilities, and in particular to surplus is flocculated in a kind of sewage treatment plants desliming system Agent regenerates the device with recycling.
Background technology
In existing desliming system, sludge mixes with flocculant, then forms dry cake, pressure-filtering process by filter press press filtration In caused press filtration water be then back to sewage plant Boosting pumping station or pretreatment section mostly.But press filtration water also exist it is unspent Flocculant, therefore press filtration water is directly back to sewage plant Boosting pumping station or pretreatment section not only wastes flocculant, also exist Following problem:1st, surplus flocculant easily assembles scum silica frost and precipitated mud and sand into Boosting pumping station;2nd, Boosting pumping station pond face forms mud Layer, easily causes to be forbidden into water applying ultrasonic lever meter to measure;3rd, Boosting pumping station bottom of pond forms mud, and sulphur is produced after anaerobic fermentation Change hydrogen, increase operating risk;4th, Boosting pumping station bottom sludge enters subsequent cell with sewage lifting, influences equipment and work Skill;5th, sludge granules block water inlet sampling pipe, analysis bottle etc., produce high maintenance cost;6th, mud enters biochemistry pool, influences Oxygen section is aerated efficiency, increases aerator power consumption and acceleration equipment abrasion;7th, surplus flocculant is cleared up or diluted by part Form be discharged into water body, certain water quality and process stabilizing risk be present.
Utility model content
In view of the above-mentioned problems existing in the prior art, the purpose of this utility model is:Desliming system waste water surplus wadding is provided Solidifying agent regeneration and recycling device, solve surplus flocculant and Boosting pumping station, pretreatment section equipment and technology stability are produced The problem of influence.
To achieve the above object, the utility model adopts the following technical scheme that:Desliming system waste water surplus flocculant regenerates With recycling device, including surplus flocculant collection device, recycling device and control device;
Surplus flocculant collection device:Including collecting and collecting pit;
One end of the collecting connects with press filtration water outlet in desliming system, one end of collecting and collecting pit Connection;
Recycling device:Including submersible sewage pump and circulation line;
The submersible sewage pump is arranged on collecting pit bottom of pond, and submersible sewage pump connects with the entrance of circulation line;
Control device:Including liquid level gauge and controller;
The test side of the liquid level gauge is arranged in collecting pit, the signal output part of liquid level gauge and the liquid level signal of controller Input connects, and the control signal output of controller and the control signal input of submersible sewage pump connect.
As optimization, in addition to check-valves, the check-valves is arranged on circulation line.
As optimization, the upper part of the collecting pit is provided with overfall.
Relative to prior art, the utility model has the following advantages that:
Desliming system waste water surplus flocculant regeneration provided by the utility model and recycling device, simple in construction, fortune Row is stable, easy to maintenance, effectively can be recycled surplus flocculant in desliming system waste water, has not only saved and has been produced into This, and reduce as much as possible on influence caused by Boosting pumping station, pretreatment section equipment and technology stability.
Brief description of the drawings
Fig. 1 is structural representation.
In figure, 11- collecting, 13- collecting pits, 21- submersible sewage pumps, 23- circulation lines, 30- deslimers, 40- backflows Well, 50- storage basins.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, the regeneration of desliming system waste water surplus flocculant and recycling device, including surplus flocculant collect dress Put, recycling device and control device;
Surplus flocculant collection device:Including collecting and collecting pit;
One end of the collecting connects with press filtration water outlet in desliming system, one end of collecting and collecting pit Connection;
As optimization, the upper part of the collecting pit is provided with overfall.When collection pit level is higher than overfall, desliming system System waste water can be discharged by overfall.
Recycling device:Including submersible sewage pump and circulation line;
The submersible sewage pump is arranged on collecting pit bottom of pond, and submersible sewage pump connects with the entrance of circulation line, and circulation line goes out Mouth connects with storage basin, and desliming system waste water enters storage basin, implements flocculation in advance to sludge in storage basin;
Preferably, also include the check-valves being arranged on circulation line.The setting of check-valves can be prevented from being pumped into and circulated Desliming system waste water in pipeline flows into submersible sewage pump.
Control device:Including liquid level gauge and controller;
The test side of the liquid level gauge is arranged in collecting pit, the signal output part of liquid level gauge and the liquid level signal of controller Input connects, and the control signal output of controller and the control signal input of submersible sewage pump connect.
Desliming system waste water surplus flocculant regeneration provided by the utility model and the operation principle of recycling device:
Sludge enters deslimer after being mixed with flocculant, and press filtration water caused by desliming process namely desliming system waste water pass through Collecting enters in collecting pit;Work liquid level is pre-set in controller and shuts down liquid level, when the liquid level in collecting pit reaches During the work liquid level pre-set into controller, submersible sewage pump, which is started working, is pumped into the waste water in collecting pit in storage basin, returns Excess sludge in stream well is entered in storage basin, and the surplus flocculant in waste water flocculates to the sludge in storage basin, so It is pumped into again in deslimer afterwards and carries out desliming;When the liquid level in collecting pit reaches shutdown liquid level set in advance in controller, dive Dirty pump is stopped, and so on.
It should be noted that it is the regeneration of desliming system waste water surplus flocculant and circulation profit that the utility model, which needs to be protected, With device in itself, rather than it uses process;In addition when using the device, work liquid level is preset in the controller and shuts down liquid Position, is prior art, and it is i.e. achievable to be that those skilled in the art need not pay creative work.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model Enclose, it all should cover among right of the present utility model.
