Problems solved by technology

[0002] At present, in petrochemical wastewater treatment, port terminals, oil depots, light industry oily, oleochemical, mechanical processing and other fields, most of the influent water is oily sewage with high emulsified oil, so most of them use electrode devices to remove oily pollution. Large, directly through the electrode device to remove oil, the effect of suspended particles is not good, and the removal rate of oil is low

Abstract

A sewage treatment equipment. Provided is a sewage treatment equipment with simple structure, reliable operation and improved efficiency. It includes a cylinder body, which includes a primary air flotation chamber and a secondary air flotation chamber separated by a partition plate; and also includes an air blowing mechanism, a buoy and a lifting mechanism, and the air blowing mechanism is located in the primary air flotation chamber. The upper part includes a gas cylinder, a gas pipe and a gas pipe two. The two ends of the gas cylinder are provided with rotating shafts, and the two ends of the buoy are connected to the rotating shafts respectively through the pull rope. Air outlet, the buoy is facing the air outlet of the air cylinder, the air cylinder is provided with a side plate, the air pipe extends out of the cylinder body and is connected to the air inlet of the air cylinder, and the air pipe extends out of the cylinder body and communicates with The side plate; the lifting mechanism includes a hanging rope and a motor, the rotating shaft of the air cylinder is connected with the hanging rope, and the hanging rope extends out of the cylinder body. The invention reduces the labor intensity of workers and has good oil discharge effect.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to sewage treatment equipment. Background technique [0002] At present, in petrochemical wastewater treatment, port terminals, oil depots, light industry oily, oleochemical, mechanical processing and other fields, most of the influent water is oily sewage with high emulsified oil, so most of them use electrode devices to remove oily pollution, but due to the high surface tension of oily water Large, directly through the electrode device to remove oil, the effect of suspended particles is not good, and the removal rate of oil is low. Contents of the invention [0003] Aiming at the above problems, the present invention provides a sewage treatment equipment with simple structure, reliable operation and high efficiency. [0004] The technical solution of the present invention is to include a cylinder, the cylinder includes a primary air flotation chamber and a secondary air flotation c...
