Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Such as Figure 1 to Figure 13 Shown, the processing method of the oily waste water of the present embodiment comprises the following steps,

[0037] 1. Transport the sewage to the water inlet chamber 11 of the treatment tank 1;

[0038] 2. Sewage enters the filter chamber from the water inlet chamber 11 to filter oil;

[0039] 3. The sewage after the oil pollution is filtered enters the water outlet chamber 12 from the filter chamber;

[0040] Sewage flows along a U-shaped path in the treatment tank 1, and the sewage enters the treatment tank 1 from the sewage inlet on one side of the treatment tank 1, and the sewage treated by the treatment tank 1 is discharged from the treatment tank 1 from the sewage outlet on the same side of the sewage inlet;

[0041] In step 2, the sewage enters the upper cavity of the filter cavity from the l...

Abstract

The invention relates to an oil stain wastewater treatment method which comprises the following steps of conveying sewage into a water inlet cavity, enabling the sewage to enter the filter cavity to filter oil stains, enabling the sewage to enter the water outlet cavity from the filter cavity, enabling the sewage to flow along a U-shaped path in the treatment tank, enabling the sewage to enter thetreatment tank from a sewage inlet in one side of the treatment tank, and enabling the sewage to be discharged out of the treatment tank from a sewage outlet in the same side of the sewage inlet after treatment, enabling the sewage to sequentially pass through N oil stain filter cavities of the filter cavities, filtering oil stains in the sewage by the oil stain filter, and intercepting the oil stains on the oil stain filter screen and decomposing the oil stains by microorganisms, due to the flow guide plate, enabling filtered water entering the water outlet cavity to flow up and down in an Sshape, and discharging filtered water which flows up and down in an S shape from one end of the water outlet cavity to the other end of the water outlet cavity out of the treatment tank from the water outlet cavity. The method has the advantages that oil stains in sewage are filtered and treated without power, the flow path of the sewage in the treatment tank is prolonged, and the sewage is subjected to more treatment processes in the same treatment space.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment method for oily waste water in catering sewage. Background technique [0002] There is an existing Chinese invention patent application with the application number CN201710457124.6 titled "Food Sewage Treatment Equipment and Its Treatment Method", which discloses a catering sewage treatment equipment and its treatment method, which includes internal partitions to form a slag removal area and a sedimentation area. , the oil-water separation area, and the box body of the sewage discharge area. The oil-water separation area is separated by a partition to form an outer oil-water separation area and an inner oil-water separation area. Oil pipe; the inner oil-water separation area is located inside the outer oil-water separation area, the top of the inner oil-water separation area is provided with a second oil collection chamber connected with the first oil collect...
