Description of drawings
Fig. 1 is a structured flowchart of the present utility model;
Fig. 2 is a use schema of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, the utility model is the specific equipment of a kind of waterworks tail water sludge dewatering treatment, it comprises sludge thickener 1, mud counterbalance cell 2, mixing tank, dewatering unit and dewatered sludge transfer roller 6 that order is provided with, mud counterbalance cell 2 links to each other with mixing tank by first water pump 3, and mixing tank is provided with flocculant concentration device 8.This equipment is by the control of PLC central authorities, and realization intelligence is controlled.
Be provided with stirrer in the mud counterbalance cell 2, the stirring by stirrer prevents sludge settling.On-line Control measuring instruments such as liquidometer and sludge concentration meter also are installed, as the foundation of mud handling capacity and flocculation agent filling rate in the mud counterbalance cell 2.
Dewatering unit adopts chamber-type press filter 5.Chamber-type press filter 5 adopts two oil cylinder compaction techniques, guaranteeing to adopt single cylinder 25MPa on the synchronous technical foundation of oil cylinder, it is big that two oil cylinder compaction techniques that pressure reaches 250T can satisfy in the treating processes need snap-in force, the highest filter pressure can reach 2.0MPa, can satisfy the high job requirement of processing pressure.Relatively have the characteristics in Stability Analysis of Structures, pressure equalization and prolongation pressure filter work-ing life with traditional single cylinder structure.
Also can adopt improvement PP+ modified elastomer membrane filter plate technology to improve pressure filter squeeze force and work-ing life.The squeeze diaphragm of compressed panel adopts improvement PP+ modified elastomer material die cast, and with squeeze diaphragm be bolted on the compressed panel, form demountable structure, convenient and simple, about 12000～15000 times of improvement PP+ modified elastomer material lifetime, maximum squeeze pressure can reach 28kgf/cm2, has directly satisfied the processing requirements of tap water tail water.
This specific equipment level of automation height, dehydrating effect is good, running cost is low, the sludge reduction effect obviously, be easy to realize the recycling sludge utilization, can realize Industry Promotion.
As shown in Figure 2, use a kind of waterworks of the present utility model tail water processing method of sludge dewatering, may further comprise the steps:
A. concentrate, the water ratio that the waterworks is produced is condensed into water ratio at 99.7%～99.1% tail water mud in sludge thickener be 97%～98% thickened sludge;
B. balance, thickened sludge is from flowing in the mud counterbalance cell, and thickened sludge is done short stay in the mud counterbalance cell, and it is constant to guarantee that sludge concentration is handled batch maintenance at each.
For preventing sludge settling, stir by the stirrer that is provided with in the counterbalance cell.
In addition, on-line Control measuring instruments such as liquidometer and sludge concentration meter also are installed in the counterbalance cell, foundation as pressure filter mud handling capacity and flocculation agent filling rate, when sludge quantity and sludge concentration change, liquid level is taken into account the dosage that sludge concentration meter output current signal control flocculant concentration device is regulated flocculation agent, guarantees the proportioning of flocculation agent and mud;
C. flocculation, the mud in the counterbalance cell to mixing tank, adds flocculation agent by the feed worm pump delivery in mixing tank, after flocculation agent and mud react, make mud form flco.
The dynamic mixed flocculation of preferred employing, the mud in the counterbalance cell is delivered in the hollow stir shaft of dynamic mixer, and flocculation agent directly mixes with the mud stirring dynamic by mixing tank.With respect to traditional hybrid mode, this method medicine mud mixes, and coagulation effect is good.
Described flocculation agent adopts polyacrylamide, is configured to 0.1% polyacrylamide solution by the flocculant concentration device, and the dosage of flocculation agent is that over dry mud per ton adds 2Kg～4.5Kg polyacrylamide.
D. solid-liquid separation, the mud flco enters dewatering unit and dewaters.
Above-mentioned dewatering unit adopts the high pressure chamber-type press filter, the mud flco enters in the high pressure chamber-type press filter airtight chamber under the effect of tubing system pressure, under the system pressure that progressively increases, free-water in the sludge system, the associative key of combination water and solids component is destroyed, solids component and water break away from, deviate from water first through filter cloth, next deviates from water through cake layer, the filter cloth discharge side is outdoor, dewatered sludge is retained in the interior filter cloth of chamber, deviate from sewage and return the mud counterbalance cell, dewatered sludge after the dehydration is opened automatically by the automatic arm-tie of pressure filter system realization filter plate, and discharging enters the storage bucket automatically, and the dewatered sludge that is stored in the bucket is sent by screw conveyor.
The feed pressure of chamber-type press filter is from 0Kgf/cm
2Progressively rise to 8Kgf/cm stage by stage
2, keep filtrate to flow out.When feed pressure reaches 8Kgf/cm
2, stop charging, start hydraulic pressure and press system, squeeze water is injected the further pressing cavity mud of membrane filter plate make its dehydration, guarantee the water ratio of mud cake by the system pressure of controlling this process.
The squeeze pressure of chamber-type press filter is from 8Kgf/cm
2Progressively rise to 12Kgf/cm stage by stage
2
The principle of work of aforesaid method is: in the tail water of waterworks is handled, help the effect of coagulating by coagulation, thickened sludge improves solids component; Use professional complete press apparatus to carry out high-pressure filteration, realize mud-water separation and sludge reduction through dehydration; Filtrate is back to original water inlet and handles again after dilution, dehydrated sludge cake outward transport or carry out mummification.Present method has solved the difficult problem of the difficult dehydration of tap water tail water mud, and mud decrement is obvious, can realize tap water system water zero discharge.
