Problems solved by technology

[0005] However, in order to ensure that the water content in the sludge reaches the required level, on the one hand, it is necessary to switch the electrodes multiple times to increase and reduce the water content in the sludge on the cathode side, so as to reduce the overall water content of the sludge, and the dehydration cycle of the entire sludge is relatively long. That is, the dehydration efficiency is low; on the other hand, in the subsequent dehydration process, the water content of the cathode is not particularly high, and the water content of the anode is even lower, resulting in a linear increase in energy consumption, resulting in a significant increase in energy consumption

Description

technical field [0001] The invention relates to the field of sludge dewatering, in particular to a sludge dewatering method and a control system. Background technique [0002] Sludge has a high water content. Due to the characteristics of the combination of water and sludge particles, mechanical dehydration has certain limitations. Thus, the method of electroosmosis dehydration is produced. Electroosmosis dehydration is to insert a metal electrode in the sludge and pass a direct current. Under the action of the electric field, the water in the sludge flows from the anode to the cathode, resulting in electroosmosis, so that the content on the anode side The amount of water is greatly reduced, while the water content of the cathode is increased, and a drainage device will be installed on the cathode side to drain water to reduce the water content of the sludge on the cathode side. [0003] In the prior art, the sludge electroosmotic dehydration device includes a dehydration c...
