Description
Technical Field
The utility model relates to a dewatering device, in particular to a device for deep dewatering of excess sludge generated by a municipal sewage treatment plant.
Background
Most of the excess sludge produced by urban sewage treatment plants in China is dewatered and then transported to a refuse landfill to be mixed and buried with domestic refuse. The sludge with the water content of about 80 percent is plastic, the bearing capacity is very low, and the problems of garbage stack landslide, settlement and the like can be caused after a large amount of sludge enters a landfill site for landfill, so that great potential safety hazards exist.
With the rapid development of economy in China, the scale of sewage treatment is larger and larger, the sludge yield is increased day by day, and large-capacity sites and transportation cost are needed for sludge landfill. Therefore, according to the stipulation of sludge treatment mixed landfill for urban sewage treatment plants (GB/T23485-2009) in China, the residual sludge of the urban sewage treatment plants can enter a landfill site for mixed landfill only after deep dehydration is carried out to reduce the water content to below 60%.
At present, the deep dehydration process of the high-pressure plate-and-frame filter press is usually adopted for deep dehydration of the excess sludge, and the deep dehydration process of the high-pressure plate-and-frame filter press has the following defects:
1) the dewatered sludge with the water content of about 80 percent in the existing sewage plant needs to be firstly adjusted into sludge with the water content of about 95 percent, otherwise, the sludge cannot enter a high-pressure plate-and-frame filter press for treatment.
2) The high-pressure plate-and-frame filter press can only operate intermittently, thus increasing the investment of a sludge dewatering system.
3) The deep dehydration process of the high-pressure plate-and-frame filter press has high energy consumption and high operation cost.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a sludge deep dehydration device that mud need not to dilute, can dewater in succession and dewater effectually, the energy consumption is low, easy the maintenance.
In order to achieve the purpose, the utility model relates to a sludge deep dehydration device, which comprises a conveyor, a dosing machine, a mixing machine and a high-pressure belt type filter press, wherein, one side of the conveyor is communicated with a sludge inlet pipe through a sludge inlet reserved interface, and the other side is communicated with a sludge inlet of the mixing machine through a sludge outlet; the mixer is also provided with a medicine inlet, and a medicine outlet of the medicine dispensing machine is communicated with the medicine inlet; the high-pressure belt filter press is provided with a mud inlet belt and a sludge outward conveying interface, the mud outlet of the mixing machine is arranged above the mud inlet belt, so that the sludge falls into the belt, and the sludge subjected to deep dehydration is discharged through the sludge outward conveying interface.
The modified medicament is precisely metered by a dosing machine and then quantitatively fed into a mixer, and the modified medicament can be a commonly used medicament in the field and is used for removing organic components in the sludge.
The utility model discloses be different with prior art in that, the utility model discloses a sludge dewatering device includes conveyer, dosing machine, mixes machine and high-pressure belt filter press, and high-pressure belt filter press has and squeezes the time weak point, can advance mud in succession and dewater, need not to dilute the processing to mud before the sludge dewatering. The high-pressure belt filter press has good dewatering effect, low energy consumption and easy maintenance, and is particularly suitable for deep dewatering of sludge in urban and industrial sewage treatment plants.
The sludge deep dehydration device of the present invention will be further explained with reference to the attached drawings.
