Embodiment 1

[0029] Embodiment 1 provides a new type of food waste treatment system and treatment process. details as follows.

[0030] see figure 1 , Embodiment 1 provides a new type of food waste treatment system, the treatment system includes a sorting tank, a dehydration tank, a liquid storage tank, a feeding device, a stirring device, a conveying device, a solid fermentation tank and a liquid fermentation tank. pool;

[0031] The sorting tank is used to separate tableware, plastics, napkins and kitchen waste; the deliquoring tank is used to separate the food waste into solid and liquid to obtain solid kitchen waste and organic waste liquid; the stirring device is used to stir mixing solid food waste and fermentation auxiliary materials; the solid fermentation tank is used to ferment solid food waste; the liquid fermentation tank is used to ferment organic waste liquid;

[0032]The sorting tank is connected to the deliquoring tank; the organic waste liquid in the deliquoring tank is...

Embodiment 2

[0040] see figure 1 , embodiment 2 is an improvement on the basis of embodiment 1. In embodiment 2, a water filter device and a drainage pipe are arranged in the sorting tank, and the water filter device uses high-temperature circulating water to preheat the food waste in the sorting tank. Melting solid grease and diluting the oil and salt content of kitchen waste; the filtered water is finally transported to the liquid storage tank one through the drainage pipeline; a slope connection is provided between the sorting tank and the deliquoring tank, so The water filtering device transports the sorted solid food waste to the deliquoring tank through the slope. A multi-layer extruding device is provided in the deliquoring pool, and the multi-layer extruding device is composed of horizontally movable extruding plates of different specifications. There is a nozzle, and the nozzle sprays water to wash the surface of the extruded plate, and the extruded plate is provided with a throu...

Embodiment 3

[0047] see figure 1 , embodiment 3 is the improvement that is carried out on the basis of embodiment 2, and liquid fermentation tank comprises aerobic fermentation tank, anaerobic fermentation tank, liquid storage tank two and aeration tank among the embodiment 3, described aerobic fermentation tank, The anaerobic fermentation tank, liquid storage tank 2 and aeration tank are airtight structures and are all equipped with manual detection channels. The aeration plate, pressurization device and oxygen ventilation device at the bottom of the aerobic fermentation tank; the organic waste liquid passes through the pipeline From the deliquification tank to the liquid storage tank 1, the organic waste liquid in the liquid storage tank 1 flows from the liquid storage tank 1 into the aerobic fermentation tank for aerobic fermentation through the pipeline, and the organic waste liquid after aerobic fermentation flows into the anaerobic fermentation tank through the pipeline The fermentat...

Abstract

The invention discloses a novel kitchen waste treatment system and process, and belongs to the technical field of kitchen waste reutilization, solid kitchen waste can be used for preparing protein feed, organic waste liquid can be used for preparing liquid organic fertilizer, the reutilization rate of the kitchen waste is high, waste is few, and the environment protection requirement is met; the treatment system provided by the invention is scientific in design, few in internal equipment and low in equipment cost; according to the treatment process provided by the invention, oil-water separation is not needed, aerobic and anaerobic continuous fermentation is directly carried out on the organic waste liquid after solid-liquid separation, and manual real-time detection is adopted in the fermentation process to ensure the trophism and safety of the liquid organic fertilizer; the kitchen waste is subjected to high-temperature circulating water filtration, so that the purposes of reducing the oil and salt content of the kitchen waste and sterilizing are achieved; the solid kitchen waste is subjected to aerobic fermentation, and the fermentation is thorough; the fermentation auxiliary agent provided by the invention is good in fermentation effect, high in macromolecular substance degradation efficiency and higher in nutrient substance utilization rate.

Description

technical field [0001] The invention relates to the technical field of kitchen waste recycling, in particular to a novel kitchen waste treatment system and treatment process. Background technique [0002] With the rapid growth of my country's economy, the acceleration of urbanization process and the general improvement of people's living standards, the output of kitchen waste continues to increase. Due to the complex composition of food waste, including oil, water, fruit peels, vegetables, rice noodles, fish, meat, bones, waste tableware, plastics, paper towels and other substances, it is easy to rot and deteriorate, emits stench, spreads bacteria and viruses, and is harmful to the ecology. The environment and living environment pose a serious threat. Compared with other garbage, kitchen waste has the characteristics of high water content, organic matter content, oil content and salt content, and rich nutrient elements, and has a very high recycling value. Therefore, it is...
