Embodiment Construction

[0024] refer to figure 1 and figure 2 The sludge dehydration and solidification treatment device of the present invention comprises a barrel body 10 for accommodating sludge, a filter pipe 20 inserted into the sludge and a strong drainage board 30 surrounding and distributed on the outside of the filter pipe 20 are arranged in the barrel body 10, and the barrel The body 10 is designed to be 20 meters high and 50 meters in diameter. The position and quantity of the strong drainage board 30 and the filter pipe 20 are arranged and distributed at intervals according to the actual situation. A vertical drainage channel is formed between the core and the filter membrane, and the strong drainage plate 30 and the jet pipe body 40 are driven into the sludge through the construction of the inserting plate.

[0025] Wherein, the jet pipe body 40 has a fluid inlet 41, a fluid outlet 42, and a water suction port 43 respectively, and the inner hollow of the jet pipe body 40 forms a jet in...

Abstract

The invention discloses a sludge dewatering and solidification treatment method and device. The sludge dewatering and solidification treatment device comprises a barrel body, a filter pipe, a forced drainage plate and a jetting pipe body. The method comprises the steps that a wall breaking solvent is added through the filter pipe to conduct wall-breaking dialysis on bound water in sludge, under the effect of a water pressure difference, the water in the sludge permeates and enters the forced drainage plate, when along with increase of the water level in the forced drainage plate, the water pressure difference is reduced, a high-pressure water pump or a high-pressure air pump is started, high-pressure water is introduced through a fluid inlet, and the water accumulated in the forced drainage plate is continuously sucked into a jetting inner cavity through a water suction port; in this way, the water level in the forced drainage plate is decreased, the water pressure difference between the forced drainage plate and the sludge is restored again, the water in the sludge permeates and enters the forced drainage plate again, and forced drainage pre-pressure is formed; in addition, when the water level in the forced drainage plate is decreased, a certain vacuum degree can be generated in the forced drainage plate, the vacuum pre-pressure is formed, the steps are repeated, and accordingly sludge solidification reaches a predetermined requirement.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge dehydration and solidification treatment method and device. Background technique [0002] In the process of sewage treatment, a large amount of sludge with extremely high water content will be produced. The treatment of sludge is generally carried out by concentration and dehydration. After concentration treatment, the water content is still very high, and further dehydration is required to reduce the water content. The existing common dehydration methods mainly include natural drying and mechanical dehydration. In addition, there are other processes such as electroosmotic dehydration, but generally there are problems such as small processing capacity and high operating costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sludge dehydration and solidification treatment method and device with low ...
