Transfer-electron type electroosmosis-advanced oxidation sludge dewatering system and dewatering method thereof

Abstract

A transfer-electron type electroosmosis-advanced oxidation sludge dewatering system and a dewatering method thereof are disclosed. The system of the invention comprises a power supply, a positive and negative convertor and an underframe. A mounting rack is arranged above the underframe. An electroosmosis liquid collecting bin which is positioned below the mounting rack is installed on the underframe. A rectangular electroosmosis reactor is installed on the mounting rack. The mounting rack is connected to a dosing injection device through a rope. The length direction of the electroosmosis reactor is the horizontal direction. Width and length of the electroosmosis liquid collecting bin are both greater than width and length of the electroosmosis reactor. The left side and right side of the electroosmosis reactor are both opened. The top of the electroosmosis reactor is provided with a sludge opening, the rear side of which is hinged to a cover plate through a hinge. The front side of the cover plate is connected to the top wall of the electroosmosis reactor through a buckle. In conclusion, sludge is dewatered through combination of electroosmosis and advanced oxidation without addition of lots of advanced oxidizing agents, heavy metal pollution will not be caused due to excessive corrosion of a plate electrode, and the technological process is simple.

Description

technical field [0001] The invention belongs to the technical field of sludge dewatering, and in particular relates to a conversion electrode type electroosmosis advanced oxidation sludge dewatering system and a dewatering method thereof. Background technique [0002] Sludge is an extremely water-soluble solid substance produced after wastewater treatment by activated sludge in sewage plants, which contains a large amount of organic matter, toxic and harmful substances and some inorganic fragments. [0003] Sludge has the characteristics of large output, high moisture content, and difficult treatment. If sludge is not disposed of or improperly disposed of, it may cause secondary pollution and endanger the health of land, water sources, residents and livestock. The study found that the premise of safe disposal and even secondary utilization of sludge is to effectively remove the water in the sludge, thereby reducing the difficulty of the disposal process. [0004] The treatm...
