A treatment device for catering wastewater

Abstract

The invention provides a treatment device for catering wastewater, which can reduce the amount of chemicals used and at the same time ensure the wastewater treatment effect. It includes a solid-liquid separation tank, a grease trap, an air flotation tank and an adsorption tank. The grease trap is connected to a slick oil collection device. The air flotation tank includes a dissolved air system and a sequentially connected drug dissolution tank, reaction tank, contact mixing tank, separation tank and Clean water tank, clean water tank connected to the adsorption tank, characterized in that: the solid-liquid separation tank is provided with a water inlet pipe, a water distribution pipe, and a grille between the water inlet pipe and the water distribution pipe; the oil separation tank is divided into area A and area B by a baffle , the lower part of the baffle is suspended in the air, the water distribution pipe is connected to area A and extends to the baffle, and area B is connected to the reaction tank through pipelines; area A is located below the water distribution pipe and has several oil-water separation channels that are arranged obliquely and parallel to each other. The upper end of the side wall of the adjacent oil-water separation channel is connected to the lower end of the baffle plate, and the lower end of the side wall is suspended, and the upper part of area B communicates with the reaction tank through a pipe.

Description

Technical field [0001] The invention relates to the technical field of catering wastewater treatment, in particular to a catering wastewater treatment device. Background technique [0002] In the existing catering wastewater treatment process, grease traps, air flotation tanks, and adsorption tanks are usually combined to remove grease, protein, cellulose, etc. in the wastewater. However, in actual use, we found that the existing grease trap has an unsatisfactory effect on removing oil slick, and some oil slick enters the reaction zone of the air flotation tank, resulting in a large amount of medicament usage, and the wastewater treatment effect is not ideal. In addition, we also found that the catering wastewater treatment system is huge and takes up a lot of space. Summary of the invention [0003] In view of the above problems, the present invention provides a catering wastewater treatment device, which can reduce the amount of medicament used while ensuring the wastewater tre...

AI Technical Summary

Problems solved by technology

However, in actual use, we found that the removal effect of the existing grease trap on the slick oil is not ideal, and some slick oil still enters the reaction zone of the air flotation tank, resulting in a large amount of chemicals used, and at the same time, the wastewater treatment effect is not ideal

In addition, we also found that the catering wastewater treatment system is bulky and takes up a lot of space
