Air floatation and oxygen limiting membrane integrated food wastewater treatment equipment and treatment process

Abstract

The invention discloses air floatation and oxygen limiting membrane integrated food wastewater treatment equipment and treatment process, wherein the air floatation and oxygen limiting membrane integrated food wastewater treatment equipment comprises a box body, and further comprises a plurality of water inlet pipes, a sludge scraping device, a stirring mechanism and a pushing mechanism, and the water inlet pipes are respectively inserted into the bottom end of the left side of an inner cavity of the box body; the sludge scraping device is arranged on the right side of the top of the box body; the stirring mechanism is assembled on the left side of an inner cavity of the box body; and the pushing mechanism is assembled on the right side of the inner cavity of the box body. According to the invention, the use defect caused by single stirring direction of traditional equipment is overcome, a flocculating agent, a coagulant aid and substances in water can be promoted to carry out a more comprehensive reaction in a positive and negative alternate motion manner, the flocculation reaction rate and the overall working efficiency of the equipment are accelerated, the practicability is higher, the accumulation of flocs on the surface of a filter screen is avoided, the effect of cleaning water while producing is achieved, it is guaranteed that water is rapidly and smoothly separated out downwards, the overall circulation rate of the equipment is increased, and the use requirements of the existing market can be better met.

Description

Technical field [0001] The present invention relates to the technical field of wastewater treatment equipment, in particular a gas floating, residential oxygenating film integrated treatment of food wastewater equipment and processing processes. Background technique [0002] Food wastewater as a classification in light industrial wastewater, in recent years, with the opportunity of the development of the third industry service industry, food processing enterprises gradually increase, food production technology with chocolate, cream, dairy, meat products, soy products, etc. High proteins have added edible pigments in the production of raw materials. Food wastewater is a variety of colors rich in protein, fat and other macromolecular organic pollutants. If the pollution environment is discharged directly, the drain network will generate a certain impact load on the sewage plant, so it must be a corresponding environmental primary treatment; the gas floating device, the wastewater i...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a kind of air flotation, oxygen-limiting membrane integrated treatment food wastewater equipment and treatment process, to at least solve the prior art when stirring after adding a certain amount of flocculant and coagulant, the direction of stirring is single, It is not conducive to the rapid and effective flocculation reaction, and it is also not conducive to the rapid precipitation of large particle sludge, and the flocs will adhere to the surface of the filter net to cause blockage and affect the downward precipitation of water for treatment, which reduces the problem of water circulation rate
