Catering sewage floatation treatment device

Abstract

The invention discloses a catering sewage floatation treatment device. The catering sewage floatation treatment device comprises a shell, an upper cavity, a centrifugal mechanism, a middle cavity anda lower cavity; the shell is of a cubic structure with the bottom provided with a pair of oil-leak ports, the top horizontally provided with a first strip hole and two opposite walls vertically provided with second strip holes; the upper cavity is arranged in the shell, a feed sleeving is vertically arranged in the top of the upper cavity, and the bottom of the upper cavity is open; the centrifugal mechanism is arranged in the upper cavity and comprises a first motor arranged on the filter screen, a centrifugal barrel fixedly connected with the output shaft of the first motor and a feed pipe communicated with the centrifugal barrel; the middle cavity is located below the upper cavity and is of a funnel-shaped structure; the lower cavity is located under the middle cavity, the top of the lower cavity is open, and the middle cavity is hermetically connected with the lower edge of the middle cavity. By the arrangement, residues, oil and water in catering sewage are screened and separated,secondary use of the residues is facilitated, oil and water are separated completely, good separation effect is achieved, and oil content of the separated sewage is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an air flotation treatment device for catering sewage. Background technique [0002] With the continuous development of my country's tertiary industry - the catering industry, people's fast-paced life and the continuous increase of the floating population, the catering industry is becoming more and more important in people's lives, and the resulting amount of catering wastewater is also increasing. The bigger the problem of environmental pollution is, the more prominent it will be. According to statistics, the catering industry in more than 100 large and medium-sized cities across the country produces nearly 3 million tons of wastewater every day, accounting for about 3% of the total discharge of urban domestic sewage, but the organic matter content accounts for one-third of the total load. There are as many as one of them, and this situation is still increasing. Cateri...

Problems solved by technology

The disadvantages are that there is a large amount of hogwash and a large-capacity container is required, so the labor intensity of moving is large, the transportation volume is large, the efficiency of manual separation is low, the separation is not complete, and the addition of chemicals will cause secondary pollution. Sewage residue for secondary use
