Embodiment 1

[0043] Embodiment 1: a kind of sludge dewatering container, such as figure 1 As shown, it includes an insulating container body 1, which is a cubic structure (wherein, it is not limited to a cube, it can be a cylinder, a cuboid, etc.), and the insulating container body 1 includes a container side wall, a bottom, a top, and a Two electrode materials 4 on the bottom and the top, the two electrode materials 4 are connected with the positive pole and the negative pole of the power supply to form two situations of upper yang and lower yin or upper yin and lower yang, wherein the upper yin and lower yang are used to flocculate the mud, and the upper yang is used to flocculate the mud. The lower shade is used for deep dehydration of the flocculated sludge.

[0044] like figure 1 and 2 As shown, the bottom end of the insulating container body 1 is open to form a mud outlet 11, the bottom is a flip-type bottom cover 3 that can close the mud outlet 11, and one side of the bottom cover...

Embodiment 2

[0055] Embodiment 2: a kind of dehydration method of dehydration container, comprises the following steps:

[0056] S1, packing, close the sludge outlet 11 of the sludge dewatering container, add sludge to the sludge dehydration container from the sludge inlet 12, and seal the sludge outlet 11 with the top cover 2 after filling;

[0057] S2, energize and dehydrate, control the lifting cylinder 6 to continue to elongate, so that the counterweight block is in conflict with the sludge, continue to control the elongation of the lifting cylinder 6 at this time, shrink the telescopic rod, and release the pulling force of the lifting cylinder 6 on the counterweight.

[0058] The electrode material 4 on the top cover 2 is connected to the positive pole of the intermittent power supply equipment, the electrode material 4 on the bottom cover 3 is connected to the negative pole of the intermittent power supply equipment, and the intermittent power supply equipment is started to energize t...

Abstract

The invention discloses a sludge dewatering container and a dewatering method by adopting the container. The sludge dewatering container comprises an insulating container body, wherein the insulatingcontainer body comprises container side walls, a bottom, a top, and electrode materials respectively arranged at the bottom and the top, the anode material is arranged at the top, and the cathode material is arranged at the bottom; an alkali adding device is further arranged on the insulating container body, wherein the alkali adding device comprises a detection unit used for detecting electric conductivity of sludge and a liquid outlet for supplying a liquid to the electrode material at the top, the supplied liquid of the liquid outlet is controlled by the detection unit, and every time whenthe electric conductivity of the sludge is reduced by a preset value A, the liquid outlet is opened for liquid supply. The alkali adding device is introduced, and the electric conductivity of the sludge is detected through the detection unit; after electroosmosis is carried out for a period of time, the electric conductivity of the sludge is reduced, and then, a bit of an alkaline solution is added to the electrode material at the top for ensuring the electric conductivity of the sludge and the dewatering effect of electroosmosis.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a sludge dehydration container and a dehydration method using the container. Background technique [0002] Sludge dehydration is a sludge treatment method that removes water from fluidized primary, concentrated or digested sludge and converts it into semi-solid or solid sludge. The sludge produced by sewage treatment has a high water content. Due to the combination of water and sludge particles, mechanical removal has certain limitations. It has an important influence on the final solid content. Generally speaking, the solid content of 20%-30% can be obtained by mechanical dehydration, and the formed sludge is also called mud cake. [0003] However, extrusion dehydration is difficult and costly, and for some difficult-to-handle sludge, the water content is still high after the mud cake is formed, and further dehydration treatment, such as thermal drying, is required. ...
