Abstract

The invention discloses a treatment device and method for treating an internal carbon source released by residual sludge through a cavitation technology, and belongs to the technical field of energy conservation and environmental protection. Comprising a feeding tank, a reaction tank, a water supplementing tank, a PK1 rotor cavitation machine, a PK2 rotor cavitation machine, an H1 spiral feeding pump and an H2 spiral feeding pump, a stirring device is arranged in the feeding tank, the feeding tank is connected with the reaction tank through a high-pressure pipeline, and the water supplementing tank is connected with the reaction tank through a high-pressure pipeline. The PK1 rotor cavitation machine, the H1 spiral feeding pump and the reaction tank form a first cavitation loop through a high-pressure pipeline, and the PK2 rotor cavitation machine, the H2 spiral feeding pump and the reaction tank form a second cavitation loop through a high-pressure pipeline. The device is simple in structure, can effectively solve the problems of insufficient carbon sources and residual sludge treatment in an activated sludge treatment process of a sewage plant, and is green, environment-friendly and pollution-free.

Description

technical field [0001] The invention relates to the technical field of energy saving and environmental protection, in particular to a device and method for treating excess sludge released by cavitation technology for internal carbon source processing. Background technique [0002] Sewage treatment refers to the purification process that treats sewage to meet the requirements of a certain water body or can be reused. People's lives and various industrial productions in cities will produce a large amount of sewage. If these sewage are not treated and discharged directly, it will be Cause serious pollution to the environment. [0003] Urban sewage treatment plants at home and abroad generally adopt the activated sludge treatment process. This process has always had a big disadvantage, that is, it will produce a large amount of excess sludge, with a moisture content of more than 99% and an organic matter content of about 70%. % to 85%, is an extremely complex heterogeneous body...
