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...

The invention discloses a sludge dehydration and solidification treatment method and device. The sludge dehydration and solidification treatment device includes a barrel body, a filter tube, a strong drainage plate and a jet tube body, and a wall-breaking solvent is added through the filter tube to reduce the bound water in the sludge. Carry out broken-wall dialysis treatment. Under the action of water pressure difference, the water in the sludge seeps into the strong drainage board. When the water level in the strong drainage board increases and the water pressure difference decreases, the high-pressure water pump or high-pressure air pump is started to pass the fluid. The inlet is connected to a high-pressure water body, so that the water accumulated in the strong drainage plate is continuously sucked into the jet cavity through the water suction port, so that the water level in the strong drainage plate is reduced, and the water pressure difference between the strong drainage plate and the sludge is restored again. The water in the sludge seeps into the strong drainage board again, forming a strong drainage preload; in addition, when the water level in the strong drainage board decreases, a certain degree of vacuum will be generated inside the strong drainage board to form a vacuum preload, and so on. Make the sludge consolidation meet the predetermined requirements.
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 ...
