An inlet (1-1) and an outlet (1-2) for remaining sewage sludge are arranged on the agitating and modulating tank (1). An overflow tank (2-1) is arranged on upper part inside the concentration tank (2) and an outlet (2-2) for flocculated and concentrated remaining sewage sludge is positioned at the bottom of the concentration tank (2). An outlet for rinsing is arranged in the overflow tank (2-1) of the concentration tank (2), and the outlet (1-2) for remaining sewage sludge of the agitating and modulating tank (1) is connected with the inlet of the pipe for sewage sludge. The outlet of pipe for sewage sludge extends into inside the concentration tank (2). The utility model greatly decreases the cost for disposing sewage sludge and labor intensity of worker because of the advantages of low current drain, water consumption, consumption of devices, as well as low maintenance costs of devices.
Description
Technical field
The utility model relates to the waste disposal plant field.
Background technology
At present, sewage mostly adopts sludge dehydration device that mud in the excess sludge and clear water are separated in treating processes.Sludge dehydration device is mainly formed by stirring modulation jar and sludge dewatering equipment, the principle of work of sludge dehydration device is, the excess sludge (water ratio is about 99.6%) that sewage is produced after biochemical treatment, by adding the flocculation agent polyacrylamide in stirring modulation jar behind the mixing, enter the sludge dewatering equipment flocculation dewatering, sludge dewatering equipment separates water in the excess sludge and mud, and clear water can turn back to Sewage treatment systems, reaches the purpose of excess sludge reduction.Its weak point is, because sewage is after biochemical treatment, it is lower to enter the excess sludge silt content that sludge dewatering equipment handles, and is generally about 0.4%, excess sludge clear water amount after flocculating is big, and the speed that clear water is separated is slow thereby influence the working efficiency of sludge dewatering equipment.
Technology contents
The purpose of this utility model is exactly that to enter the excess sludge silt content that sludge dewatering equipment handles lower at existing, a kind of sludge dewatering concentrating unit that influences the deficiency of sludge dewatering equipment working efficiency and provide, it is by stirring modulation jar 1, concentration tank 2 and sludge pipe 3 are formed, stir modulation jar 1 and be provided with excess sludge import 1-1 and excess sludge outlet 1-2, be provided with spilling water weir notch 2-1 at concentration tank 2 internal upper parts, be provided with flocculation in concentration tank 2 bottoms and concentrate excess sludge outlet 2-2, in the spilling water weir notch 2-1 of concentration tank 2, be provided with clear water output 2-3, the excess sludge outlet 1-2 that stirs modulation jar 1 communicates with the water-in of sludge pipe, and the water outlet end of sludge pipe is inserted in the concentration tank 2.It cleans water pipe 4 in addition, and the water-in of cleaning water pipe 4 communicates with the clear water output 2-3 of spilling water weir notch 2-1, and the water outlet that cleans water pipe 4 communicates with the excess sludge import of stirring modulation jar 1, on cleaning water pipe 4 valve is installed.
The utility model has the advantages that: after it can add excess sludge earlier flocculation agent flocculation concentration, secondary added the flocculation agent flocculation and enters the sludge dewatering equipment dehydration again.Excess sludge is entered before the sludge dewatering equipment, wherein existing water over half is separated in concentration tank, make in the excess sludge silt content surpass more than 1%, the excess sludge silt content that enters like this in the sludge dewatering equipment is enhanced about more than once, clear water in the former excess sludge has over halfly need not pass through sludge dewatering equipment, is equivalent to make the sludge dewatering equipment working efficiency to be enhanced about more than once.Promptly improved mud handling capacity in the unit time more than one times, reduced the working time of sludge dewatering equipment, reduced power consumption, water consumption, equipment loss, maintenance of the equipment maintenance cost, thereby greatly reduce the sludge treatment cost.Also reduced simultaneously labor strength.Use this device also can save the traditional sludge concentration basin, saved the investment cost of sludge thickener.
Description of drawings
Accompanying drawing 1 is the utility model structural representation, and white arrow is that clear water flows in the accompanying drawing, and black arrow flows to for concentrating excess sludge; Accompanying drawing 2 is the utility model concentration tank sectional structure synoptic diagram.
Embodiment
Stir modulation jar and concentration tank all with steel plate processing, stirring modulation jar and the stirring in the existing sludge dehydration device, to modulate jar structure the same, and agitator is installed in jar, and the height of concentration tank can be 8 meters, 2 meters of diameters.The spilling water weir notch is the groove that is provided with along tank skin in concentration tank, the wide 150mmm of overfalling weir bottom land, and high 160mm, the overfalling weir trench bottom can be reinforced with angle steel, and the upper surface of spilling water weir notch is provided with the sawtooth mouth.At each import and export place valve can be installed.The water-in that cleaning is assured communicates with the clear water output of spilling water weir notch, and water outlet communicates with the excess sludge import of stirring the modulation jar, on the cleaning water pipe valve is installed.
Other by specification and the connection of Figure of description mode of connection get final product.
Using method: former adding sludge dehydration device is stirred excess sludge in the modulation jar, after adding the flocculation agent polyacrylamide, be evacuated in the stirring modulation jar of this device behind the mixing, enter (will close the rinse water pipe valve this moment) in the concentration tank.In concentration tank,, there is clear water over half to overflow into the spilling water weir notch on top approximately, discharges through clear water output through flocculation sediment.Flocculation mud sinks down into the bottom, after concentrated excess sludge outlet adds the flocculation agent polyacrylamide, from the stirring modulation jar 5 that flow in the sludge dehydration device, after stirring, sends into sludge dewatering equipment 6 again and carries out processed again.The effect of cleaning water pipe is before sludge dehydration device quits work, close earlier and enter the excess sludge import that this device stirs the modulation jar, open the rinse water pipe valve, make clear water flow into this device and stir the modulation jar, with clear water this device is cleaned, the muddy water of cleaning is delivered to sludge dewatering equipment, stops sludge dehydration device after this device cleans up substantially again, after avoiding stopping sludge dehydration device, mud is difficult to remove after accumulating and doing in this device.
