Energy-saving and environmentally-friendly treatment device for oil-containing sewage

Abstract

An energy-saving and environmentally-friendly treatment device for oil-containing sewage is provided, including a first purification barrel. A material feeding pipe is inserted into the top of the first purification barrel. The top end of the material feeding pipe is fixedly connected to a feeding hopper, and the bottom end of the material feeding pipe is fixedly connected to a water inlet of a filter bag. Left and right sides of the upper surface of the filter bag are fixedly connected to bottom ends of two supporting bars respectively. The top ends of the supporting bars are fixedly connected to the top of the inner wall of the first purification barrel. In the device, through arrangement of the first purification barrel, the material feeding pipe, the feeding hopper, the filter bag, thesupporting bars, an activated carbon layer, a first filtration layer, a second filtration layer, a drainage pipe, a guide hopper, a purified water tank and a first communicating pipe, when sewage enters the first purification barrel through the feeding hopper and the material feeding pipe, the sewage is purified in the activated carbon layer to remove pollutants in water, and the sewage is subjected to filtration between the first and second filtration layer to remove filter dregs.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an energy-saving and environment-friendly oily sewage treatment device.
