Industrialized treatment facility and method for catering wastes

Abstract

The invention discloses an industrialized treatment facility and method for catering wastes. The facility is composed of a filter, an oil-water separator, an oil sump, a sedimentation tank, a neutralization and deodorization tank, a storage tank, a tail gas absorption system, a waste water treatment system and a waste residue treatment system, wherein the filter and the oil-water separator are arranged in the oil sump, the oil sump, the sedimentation tank, the neutralization and deodorization tank and the storage tank are sequentially communicated; a waste water pump is arranged between the oil sump and the sedimentation tank, and a boiled oil pump is arranged between the sedimentation tank and the neutralization deodorization tank; and the tail gas absorption system is respectively communicated with the filter, the oil-water separator, the sedimentation tank and the neutralization and deodorization tank. The production process in the invention comprises six procedures of solid-residue separation, oil-water separation, neutralization and deodorization, tail gas purification, sewage treatment and waste residue treatment. In the invention, catering wastes are subjected to physical and chemical treatment under the close condition, and no waste gas, waste residue or waste water is discharged; separation, deodorization, decolourization and other technologies are utilized to separate waste oil from the catering wastes, and the waste oil is used for producing industrial production raw materials of biodiesel, lubricating grease and the like; and 'three wastes' produced in the production process are recycled by adopting chemical and physical methods, thus biomass fuel, reuse water for life and purified air are obtained. The invention thoroughly avoids secondary pollution in waste oil refining and separating process and realizes recycling of waste water, waste gas and waste residue.

Description

technical field [0001] The invention relates to comprehensive utilization technology of food and beverage waste, in particular to facilities and methods for industrial separation, pollution control and recycling of food and beverage waste grease and residue. Background technique [0002] With the acceleration of people's life rhythm and the rapid expansion of urbanization construction, the development of the catering service industry has become increasingly popular. [0003] Usually, the recycling method of waste oil and residues in catering such as waste oil and swill oil: one is personal collection, the residue is fed to pigs, and the waste oil is separated and sold; the other is a large-scale waste oil collection method—simple The separation and classification of waste oil and swill oil are placed in a large pot or an open oil storage tank, heated by fire or steam, and a small boiler is used for simple oil-water separation. The problems of this method are: 1. , the oil-w...
