Description

Buried sewage pool Technical Field The application relates to the technical field of sugar manufacturing, in particular to a buried sewage pool. Background During the production period of the squeezing and cleaning workshops of the laboratory and the production line of the sugar refinery, sewage is produced every day. The discharged sewage can be discharged after being treated and meeting the environmental protection requirement. The sewage generated in the above environments is mainly collected in the buried sewage collecting barrels for respective recovery treatment. Submersible pumps are arranged in the barrels. The laboratory sewage is conveyed to a sewage collecting tank of a cleaning workshop, is discharged or recycled after being treated by an end sewage treatment system together with other production sewage, and the sewage is collected by a smaller sewage tank in a squeezing and cleaning workshop.
