Three-phase separation and waste water purification standard treatment device of kitchen waste including 'waste oil' and solid waste and kitchen waste water

Abstract

The invention discloses a three-phase separation and waste water purification standard treatment device of kitchen waste including 'waste oil', solid waste and kitchen waste water. The three-phase separation and waste purification standard treatment device of the kitchen waste including the 'waste oil', the solid waste and the kitchen waste water is mainly composed of a shell body, a solid-liquid separation chamber, a filtering bag with meshes, a liquid level displayer, an oil-water interface detector, a numerical control electric valve which discharges the 'waste oil', a flowmeter of the 'waste oil', a collection tank of the 'waste oil', a blower, an air heating device, a filtering tank, a drug adding tank and the like. According to the three-phase separation and waste water purification standard treatment device of the kitchen waste including the 'waste oil', the solid waste and the kitchen waste water, oil and water separation and waste water purification are carried out in the same device, an equipment structure is simplified, the water quality after being purified is in line with each indicator of 'water quality standard of sewage discharged into the city sewer' (CJ3082-1999), The three-phase separation and waste purification standard treatment device of the kitchen waste including the 'waste oil', the solid waste and the kitchen waste water has the advantages that the size is small, the investment is low, either manual or automatic operation is available and the like, and obvious creativity, novelty and good industrial applicability are provided.

Description

technical field [0001] The invention relates to a device for three-phase separation of "waste oil", solid waste, and kitchen waste water from kitchen waste, and a waste water purification and standard treatment device, belonging to the field of environmental protection equipment; Background technique [0002] With the continuous improvement of people's lives, the amount of food waste generated is increasing day by day. Standardized, intelligent and low-cost collection of food waste in restaurants and kitchens can completely prevent the "gutter oil" in food waste from being put on the table, from the source Collecting and treating "waste oil" well, avoiding kitchen waste directly entering the food chain as feed, and maintaining people's food hygiene and health are major issues of concern in today's society and have great environmental and social significance. [0003] Generally, in kitchen waste, solid waste (such as chopsticks, leftovers, etc.) accounts for about 10% (wt%), ...

Problems solved by technology

[0003] Generally, in kitchen waste, solid waste (such as chopsticks, leftovers, etc.) accounts for about 10% (wt%), "waste oil" accounts for about 5-10% (wt%), and waste water accounts for 85-80% About (wt%); There are many reports on the oil-water separation equipment of relevant food waste, as in CN101215020, disclose " kitchen waste waste water grease integrated separation device and method ", in CN202492418U, disclose " a collection Oil-Water Separator for Waste Oil"; the existing open and market-applied oil-water separation equipment for food waste mainly adopts the following principle of oil-water separation, namely: utilizing the immiscibility of non-polar oil and polar water, and The density of water is greater than that of oil and other physical properties; since the natural separation of oil and water takes a certain amount of time, and this time is closely related to the specific conditions such as the flow rate and temperature of the swill to be treated, the sewage in the catering industry Most of the grease and suspended particles are very small. The dispersed oil, emulsified oil, dissolved oil and solid adhered oil in the s
