Abstract

The invention relates to an oily wastewater treatment device. The oily wastewater treatment device aims to solve the technical problem of low sewage treatment efficiency caused by the fact that a plurality of existing sewage treatment devices in the prior art only simply adopt a filtering mode and cannot remove waste oil contained in sewage. The device of the invention comprises a rotational flowair floater, a pre-filter for filtering impurities and a coalescence filter for gathering waste oil which are sequentially arranged in the flow direction of wastewater, wherein the pre-filter comprises a first tank body, a plurality of first filter elements vertically arranged in the pre-filter and a cleaning assembly arranged in the first tank body and used for cleaning the first filter elements;and the coalescence filter comprises a second tank body and a plurality of second filter elements which are vertically and detachably arranged in the second tank body and used for coalescing waste oil entering the second tank body. The device is simple in structure and mainly used for oil removal treatment of wastewater.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an oily wastewater treatment device for oil removal. Background technique [0002] Sewage is mixed with a certain amount of suspended impurities and waste oil. Generally, simple filtration is used in sewage treatment, and the filtrate is treated again in a concentrated manner. Doing deep processing brings certain difficulties. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the prior art, and propose an oily wastewater treatment device, which is used to solve the problem that some existing sewage treatment devices mentioned in the background technology simply adopt filtering methods and cannot remove the waste oil contained in the sewage. , resulting in the technical problem of low sewage treatment efficiency. [0004] To achieve the above object, the present invention adopts the following technical solutions:...
