Abstract

The invention discloses an oil-removing and slag-skimming device for sewage treatment. The device comprises a sewage pool, a first partition plate and a second partition plate which are distributed ina horizontal structure are welded on the inner wall of the bottom of the sewage pool, the first partition plate is positioned between the side inner wall of the sewage pool and the side outer wall ofthe second partition plate, a precipitation cavity is defined by the side inner wall of the sewage pool, the bottom inner wall of the sewage pool and the side outer wall of the first partition plate,an oil filtering cavity is defined by the bottom inner wall of the sewage pool, the side inner wall of the first partition plate and the side outer wall of the second partition plate, a drainage cavity is formed between the bottom inner wall of the sewage pool and the side surface inner wall of the second partition plate and a sludge discharge pipe, a water inlet pipe, an oil outlet pipe and a water discharge pipe are inserted into the positions, close to the bottom and the top, of the outer wall of the side face of the sewage pool correspondingly. Sewage in the device sequentially enters allthe cavities through the gravity of the sewage, the purpose of oil removal and skimming is achieved through different densities of waste oil, sewage and residues, and the device is simple in overallstructure.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oil removal and scum removal device for sewage treatment. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of being discharged into a certain water body or reused. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc. Various fields are also increasingly entering the daily life of ordinary people. [0003] Most of the existing degreasing and scumming devices for sewage treatment have complex structures and are equipped with a large number of transmission mechanisms, which causes serious wear between parts and wastes energy, and most of the existing degreasing and scumming devices for sewage treatment are open structures , When the device is running, the smell of sewage is di...
