Abstract

A sludge concentration-dehydration-drying integrated treatment plant and a treating method thereof are disclosed. The integrated treatment plant includes a sludge concentration device and a sludge deep-dehydration device. The sludge concentration device includes a wedge-shaped filter screen and a rotating first spiral shaft. The wedge-shaped filter screen includes a low-concentration sewage filtration segment, a sludge concentration segment and a sludge extruding segment. The first spiral shaft includes a central shaft, a first rubber ring and a first spiral blade. The sludge deep-dehydration device includes a spiral conveying-extrusion integrated machine and an extruding dehydrating chamber. The spiral conveying-extrusion integrated machine includes a second spiral blade, a conveying shell and a second spiral shaft varying in pitch. The extruding dehydrating chamber includes a left filtration plate, a right filtration plate and a middle filtration plate. The left and right filtration plates adopt the middle filtration plate as an axis and expand outward or close inward. The integrated treatment plant overcomes problems of the prior art that water contents after sludge treatment are high and a running cost is high.

Description

technical field [0001] The invention relates to the field of sludge concentration and dehydration and drying, in particular to an integrated treatment device for urban domestic sludge or sludge concentration, dehydration and drying of farms and septic tanks and a treatment method thereof. Background technique [0002] At present, in the process of sewage treatment, a by-product——sludge will be produced. Sludge is a solid sediment produced by water and sewage treatment. Sludge dehydration is to concentrate or digest sludge to remove water and convert it into A sludge treatment method of semi-solid or solid sludge. Energy conservation and emission reduction is one of the basic national policies for the sustainable development of my country's economy. With the strengthening of water environment governance and protection, the treatment technology of sludge dewatering is also developing continuously. [0003] The existing urban domestic sludge or sludge concentration and dehydra...
