Oily sewage treatment apparatus and treatment method thereof

Abstract

The invention relates to an oily sewage treatment apparatus and a treatment method thereof. An upper precipitation zone and a lower precipitation zone are arranged to realize full precipitation, the bottom of a first precipitation zone forms an inclined plane used for recovering a waste material, a second precipitation zone is formed below the inclined plane of the first precipitation zone, the first precipitation zone is connected with the second precipitation zone through a first overflow pipeline, and a control valve controlled by a water level induction switch is arranged in the pipeline. The second precipitation zone is connected with an oil-water separation zone through a second overflow pipeline, an oil collecting chamber and an oil overflow opening are arranged at the top of the oil-water separation zone, the oil-water separation zone and the oil collecting chamber are divided by a separator plate to form a left chamber and a right chamber, and a conduit used for conducting the left chamber with the right chamber is arranged on the separator plate; and a filter zone and a clear water zone are arranged adjacent to the right chamber of the oil-water separation zone, a filter layer is arranged in the filter zone, the top of the filter layer is connected with the bottom of the right chamber of the oil-water separation zone through a third overflow pipeline, the bottom of the filter layer is connected to the upper portion of the clear water zone through a flow guiding tube provided with a switch valve, and the clear water zone is correspondingly provided with a water discharge opening in order to realize step-by-step filtering discharge of sewage.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to oily sewage treatment equipment and a treatment method thereof. Background technique [0002] With the accelerated pace of social development and the continuous expansion of urban scale, urban pollution has become a major problem in today's society, especially water pollution. Not conducive to environmental sustainable development. For the treatment of sewage, the most important thing is to control the source of pollution. Only by dealing with the source of pollution in time can we ensure the follow-up treatment and reduce pollution. For this reason, prior art has disclosed some sewage treatment equipments, and these sewage treatment equipments mostly comprise settling area, filtering area, and settling area is used for the sedimentation of sewage, and filtering area then carries out filtration and purification to sewage, according to different industry needs, for example For indus...
