Grease waste liquid treatment device

Abstract

The invention discloses a grease waste liquid treatment device. The treatment device comprises a treatment box body, an aeration system, a rotating shaft system and a central rotating shaft driving system, an inner cavity of the treatment box body is divided into an oil-water separation cavity and a multi-stage waste liquid treatment cavity, and the treatment device can be used for carrying out aerobic treatment, anaerobic treatment or anaerobic and aerobic composite treatment on oil-removed waste liquid after oil-water separation according to requirements. The internal structure of the treatment device is reasonably improved; the oil-water separation effect of the grease waste liquid is enhanced based on the gravity-air floatation principle; meanwhile, a biological treatment function is integrated; aerobic treatment, anaerobic treatment or anaerobic and aerobic composite treatment of the deoiling waste liquid obtained after oil-water separation can be respectively realized as required; resource utilization and environmental protection of the grease waste liquid are facilitated, the purposes of simplifying equipment and reducing treatment cost are achieved while high efficiency isachieved, and the method is particularly suitable for common families, catering merchants of various scales, central kitchens and other scenes.

Description

technical field [0001] The invention belongs to the technical field of grease waste liquid treatment, and in particular relates to a grease waste liquid treatment device for separating oil and water from kitchen grease waste liquid and biologically treating the oil-removing liquid phase to discharge standards. Background technique [0002] With the rapid development of my country's urbanization process and the improvement of people's living standards, the development of the catering industry has been greatly promoted, and a large amount of kitchen waste has also been generated. Due to the particularity of the nature of kitchen waste, a series of social and environmental problems will arise if it is not treated effectively. [0003] Kitchen oil waste has become an important factor threatening human health. Kitchen oil waste liquid is extremely perishable and degenerate, emits stench, and spreads bacteria and viruses. There are many toxic substances such as (benzoflower, benz...

AI Technical Summary

Problems solved by technology

If the untreated kitchen grease waste liquid is directly discharged to natural water bodies, it will not only reduce the reoxygenation rate of the water body, but also consume dissolved oxygen in the water, deteriorate the water quality, and seriously affect the living environment of aquatic organisms and fish; if directly discharged As far as urban sewage treatment plants are concerned, due to the refractory nature of grease, an oil film will be formed on the surface of the wastewater, which will affect the normal metabolic process of activated sludge and biofilm, and increase the load of urban sewage treatment plants; and grease can condense on the inner wall of the pipeline and is not easy to Clean up, which in turn affects the water passing capacity of the urban drainage network
