Floating oil absorption system for sewage treatment

Abstract

The invention discloses an floating oil absorption system for sewage treatment, which comprises a columnar floating oil absorption tower, a cylindrical floating oil absorption tank in the floating oilabsorption tower, a sewage leading-in pipe and a sewage leading-out pipe, the outlet of the sewage leading-in pipe is communicated with the floating oil absorption tank, and the inlet of the sewage leading-out pipe is communicated with the floating oil absorption tank. The floating oil absorption device is simple in structure, wherein the disc-shaped floater divides the circular liquid level intothe continuous vortex-shaped floating oil absorption water channel, and the floating oil collection hole of the floating oil absorption device can gradually sweep through the position below the liquid level of the vortex-shaped floating oil absorption water channel in the anticlockwise vortex direction; besides, the first floating oil guide blades and the second floating oil guide blades play a role in gathering floating oil, so that the vortex-shaped floating oil in the water channel can be absorbed more thoroughly.

Description

technical field [0001] The invention belongs to the field of sewage treatment. Background technique [0002] Before the sewage purification treatment, it is necessary to absorb the waste oil of various components floating on the liquid surface of the sewage before proceeding to the next step. The floating oil includes engine oil, kerosene, diesel oil, lubricating oil and other liquids whose specific gravity is smaller than water ; [0003] The existing absorption method is to set the oil slick absorber at the liquid level in the middle area of ​​the absorption pool, and then continue to absorb the oil slick in the middle of the pool, so that the oil slick around will gradually replenish to the middle area, thereby making the The oil layer on the liquid surface is gradually thinned, so as to absorb the oil slick. This absorption method will gradually thin the oil layer during the absorption process, so the absorption efficiency will become lower and lower as time goes by, an...

Problems solved by technology

[0003] The existing absorption method is to set the oil slick absorber at the liquid level in the middle area of ​​the absorption pool, and then continue to absorb the oil slick in the middle of the pool, so that the oil slick around will gradually replenish to the middle area, thereby making the The oil layer on the liquid surface is gradually thinned, so as to absorb the floating oil. This kind of absorption method will gradually thin the oil layer during the absorption process, so the absorption efficiency will become lower and lower as time goes by, and it cannot be absorbed completely theoretically.
