Multi-stage oil-water separator

Abstract

The invention relates to the technical field of water treatment equipment, in particular to a multi-stage oil-water separator. The multi-stage oil-water separator is characterized in that a first support is fixedly arranged on a first reservoir; a first conveying belt is fixedly arranged on the first support; a second conveying belt is fixedly arranged on the first support; an impurity pump is fixedly arranged on a base; a filter screen is embedded and fixed in an upper port of a pressurizing tank; an oil-water separator is fixedly arranged on the base; a second water storage tank is fixedly arranged on the base; the outlet end of the oil-water separator is inserted into the second water storage tank; and a sealing cylinder penetrates through and is fixed at the lower end of the rear sidewall of the pressurizing tank. When the multi-stage oil-water separator conducts solid waste separation, floating solid waste treatment is firstly carried out, then precipitated solid waste treatmentis carried out in a pressurizing mode, then solid waste of different layers is independently treated, so the treatment efficiency of different procedures cannot be affected; and meanwhile, the flow speed of sewage during filtering can be increased and a filtering speed can be increased by adopting the pressurizing treatment mode.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a multistage oil-water separator. Background technique [0002] Oil-water separation equipment is a kind of equipment for treating sewage mixed with insoluble oils. In addition to being used in large-scale sewage treatment plants, it will also be integrated and installed in the sewer pipeline of restaurants such as restaurants; most of the existing oil-water separation equipment only It has a structure of one-stage solid-liquid separation and one-stage oil-water separation. When the sewage contains solid wastes of different layers such as floating matter and sediment, the working efficiency of the solid waste filtering device in the equipment will be significantly reduced, which will affect the The working efficiency of the equipment needs to be improved. Contents of the invention [0003] The object of the present invention is to aim at the defects and defic...
