Description

Oily wastewater treatment device

Technical Field

The utility model relates to a sewage treatment technical field, concretely relates to oily wastewater treatment device for deoiling.

Background

A certain amount of suspended impurities and waste oil are mixed in the sewage, a simple filtering mode is adopted for common sewage treatment, the filtered substances are treated in a concentrated mode, and the waste oil mixed in the sewage cannot be effectively removed by simple filtering, so that certain difficulty is brought to subsequent advanced treatment of the sewage.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is to prior art not enough, provides oily effluent treatment plant for some current sewage treatment plant that mention in the solution background art only adopt the filtration mode simply, can not get rid of the waste oil that contains in the sewage, thereby cause the technical problem that sewage treatment efficiency is low.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

oily effluent treatment plant includes according to the waste water flow to the whirl air supporting ware that sets gradually, filter impurity's prefilter and the coalescence filter who is used for making waste oil assemble, the prefilter includes first jar of body, a plurality of vertical first filter core of locating in the prefilter and locates the first jar of internal washing subassembly that is used for wasing a plurality of first filter cores of internal, the coalescence filter includes that the second jar of body and a plurality of vertical and all dismantlement formula locate the internal second filter core of second jar to be used for the coalescence to enter into the internal waste oil of second jar.
