[0002] Sewage itself has good resource utilization potential. Objectively, a large amount of organic matter is contained in sewage, which can be converted into available resources. For example, an anaerobic expanded granular sludge reactor is used to treat the pretreated concentrated carbon source hydrolysis solution of sewage to generate available biogas, etc. However, there are some problems that are difficult to solve in the sewage treatment process: Usually, sewage enters the reactor from the bottom water distribution system, making the wastewater contact with the granular sludge in the EGSB reactor, and then the treated sewage is discharged. However, during the reaction process, the reactor works continuously, so it is possible that the wastewater is discharged before the reaction is complete, thus affecting the surrounding environment. Content of the Utility Model

[0003] In view of the above, the utility model provides a sewage carbon source concentration equipment to solve the problems put forward in the above background technique.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a sewage carbon source concentration equipment, including a device main body, the device main body includes a sewage tank for storing sewage, a reaction device for reacting sewage, and an extraction device.
