Problems solved by technology

The existing problems are: the speed of mechanical and biochemical treatment is relatively slow, on-site biogas resource utilization, and the equipment is large in size and difficult to arrange and place
Chinese patent 201210002881.1 discloses a comprehensive treatment system for kitchen waste. It is necessary to collect the garbage first, crush the collected garbage, squeeze it, separate the solid and liquid, dry the obtained solid garbage and store it, and separate the liquid garbage from oil and water. Storage; the existing problems are: the solid waste hot air drying device consumes a lot of energy, and produces a large amount of waste heat and odor emissions
The existing problems are: the extrusion operation controlled by weighing is an intermittent operation mode to realize the solid-liquid separation of food waste, which cannot adapt to the irregular and complex situation of food waste discharge, and it is difficult to implement control. In addition, the oil-absorbing steel The belt can only realize the separation of floating oil, but it is completely ineffective for the separation of dispersed oil and emulsified oil in oil water

Embodiment Construction

[0016] See figure 2 , a method for recycling food waste, the steps of which include: food waste or kitchen washing water, passing through a drying net, coarsely filtered food waste enters the integrated ultra-fine grid (aperture 0.5 mm), screw extrusion The automatic solid-liquid separation device of the conveyor and high-pressure backwashing system is used for separation. The separated solid waste is transported to a low-temperature storage barrel for storage (5°C), and the separated liquid waste is discharged into a small grease trap.

[0017] The small grease trap collects floating oil and enters the grease collection barrel. The water from the grease trap enters the water collection tank, and the water stored in the water collection tank is pumped into the membrane separation device. The sewage separated by the membrane flows back into the grease trap, and the separated clear water is reused as reclaimed water, which can be used as water for the high-pressure recoil syst...

Abstract

The invention discloses a recovery processing method of food waste. The recovery processing method of food waste comprises the following steps of: firstly screening the waste with a coarse filter system; filtering the food waste after being screened; conveying the waste into a low-temperature storage barrel for storage through screw extruding; and carrying out oil-water separation and advanced treatment by separated oil and water entering an oil-water separation device. The recovery processing method of food waste adopting the scheme has the characteristics of being simple in structure, convenient to realize, small in equipment volume, high in degree of automation, high in processing speed and low in cost, and is capable of efficiently carrying out in situ reducing, innoxious and resource processing on the food waste; sewage water can achieve the standard of reclaimed water reuse; and much water resource can be saved.

Description

technical field [0001] The invention relates to the field of kitchen waste treatment, in particular to a recovery and treatment method for on-site reduction, harmlessness and resource utilization of restaurants and kitchen waste. Background technique [0002] At present, various food safety issues caused by kitchen waste such as "gutter oil" and "garbage pigs" have attracted social attention, and have become a major problem affecting the lives and health of the people. The problem of kitchen waste has been highly valued by the relevant state departments, and a series of policies and regulations have been issued successively to require the harmless treatment and resource utilization of kitchen waste, so as to rectify from the root cause. [0003] Chinese patent 201210267197.6 discloses a treatment process of kitchen waste, including solid-liquid separation, solid material crushing and beating and anaerobic digestion to obtain biogas and organic fertilizer resources, so as to ...
