Abstract
The invention relates to a sewage processing device and a sewage processing method, and specifically refers to deposition pond a <{EN0}>supermatant discharge system and a sludge condensation method; the supermatant discharge system comprises the deposition pond; the bottom of the deposition pond is provided with a mud inlet pipe, and an upper portion of the deposition pond is provided with a water discharge pipe; the supermatant discharge system also comprises mud discharge equipment including a mud discharge pipe; an inlet of the mud discharge pipe is positioned on the bottom of the deposition pond; the mud of the previous mud processing equipment enters the deposition pond through the mud inlet pipe, when the mud settles on the bottom of the deposition pond and the supermatant is positioned on the upper portion, the supermatant can be discharged by the water discharge pipe on the upper portion of the deposition pone, and condensation mud is discharged to the next mud processing equipment through the mud discharge equipment; mud water content and mud volume are reduced.
Description
Technical field
the present invention relates to a kind of waste disposal plant and sewage water treatment method, specifically a kind of sludge sump supernatant liquor blowdown system and sludge concentration method.
Background technology
?activated sludge process is most widely used sewage disposal technology in the world at present, in treating processes, can produce a large amount of mud.In Sewage Plant operational process, preliminary sedimentation tank, second pond, advanced treatment all can produce mud.The moisture percentage in sewage sludge of general primary settling tank of sewage plant is probably in 97% left and right, and the moisture percentage in sewage sludge of second pond is probably 99%, and the moisture percentage in sewage sludge of advanced treatment is probably more than 99%.The sludge volume that these operations produce is large, and water ratio is high, and when processing, infrastructure investment is high, and production run cost is large.
Therefore, reduce moisture percentage in sewage sludge in Sewage Plant operational process, carry out mud and concentrate, reduce mud volume, be conducive to Sewage Plant and save energy and reduce the cost and reduce working cost.
Summary of the invention
?the invention provides a kind of for reducing sludge sump supernatant liquor blowdown system and the sludge concentration method of sludge moisture content and mud volume.
Technical scheme of the present invention is: a kind of sludge sump supernatant liquor blowdown system, and it comprises a sludge sump, and the bottom of described sludge sump is provided with into mud pipe, and top is provided with water shoot; It also includes soil discharging facility, and described soil discharging facility comprises shore pipe, and the entrance of described shore pipe is positioned at the bottom of sludge sump.
On described water shoot, be provided with control valve.
In sludge sump supernatant liquor blowdown system claimed in claim 1, mud in previous sludge treatment device enters sludge sump by entering mud pipe, when sludge settling is to the bottom of sludge sump, when supernatant liquor is positioned at top, supernatant liquor is discharged by the water shoot on sludge sump top, then the mud after concentrated is drained in a rear sludge treatment device by soil discharging facility.
Advantage of the present invention is: utilize the effect of mud self gravitation, the moisture in mud is separated in to top, and then supernatant liquor is discharged, reach the effect concentrated to mud.On water shoot, be provided with control valve, can adjust emission flow and intermittent time according to the size of entering mud concentration.
Accompanying drawing explanation
Fig. 1 is the structural representation of sludge sump supernatant liquor blowdown system of the present invention;
