Embodiment 1
[0041] refer to figure 1 As shown, the present invention is a kind of food waste recycling process, comprising the following steps;
[0042] Step 1. Solid-liquid separation: take the kitchen waste, and use a solid-liquid separation device to separate the food waste into solid-liquid phase to obtain solid-phase kitchen waste and liquid-phase kitchen waste;
[0043] Step 2. Solid waste sorting: effectively separate and sort the organic matter and inorganic matter in the solid-phase food waste through the food waste pretreatment equipment;
[0044] Step 3, solid organic waste treatment: steaming, extruding and pulverizing a part of the organic matter sorted in step 2 to obtain organic breeding feed, and using the obtained organic breeding feed for black soldier fly breeding;
[0045] Step 4, liquid waste treatment: combine the kitchen waste in the liquid phase in step 1 and the liquid obtained in the extrusion process in step 3 to obtain a liquid phase material, and use an oil-w...
Embodiment 2
[0065] Wherein, step 5 aerobic fermentation process following steps:
[0066] a. Separately crush organic waste and agricultural waste;
[0067] b. Mix 40kg of organic matter, 20kg of insect excrement and residual substances, 5kg of microbial agent and 15kg of sludge residue in the solid-phase kitchen waste and evenly stack them on the bottom, and then pile up 100kg of crushed organic waste and agricultural waste on the bottom Finally, 150kg of humic acid concentrated water will be added from the top of the pile by spraying;
[0068] c. Since the mixture is put in, within 72 hours, the fermentation temperature reaches 55-60°C and lasts for 3-5 days, then the temperature drops naturally, and the fermentation is completed when it drops to 35-40°C.
[0069] Among them, 50kg of straw, 80kg of weed leaves, and 20kg of fruit shells are used for agricultural waste; waste paper is used for organic waste.

Abstract
The invention discloses a kitchen waste recovery treatment technology and relates to the technical field of resource recovery and recycling treatment. The kitchen waste recovery treatment technology comprises the following steps of 1, solid-liquid separation, 2, solid waste sorting, 3, solid organic waste treatment, 4, liquid waste treatment, 5, aerobic fermentation, and 6, concentrated fermentation. With the adoption of the kitchen waste recovery treatment technology, the purpose that a recycling resource in kitchen waste is recovered to the greatest extent is achieved, and at the same time,occupation and pollution on an environmental resource are reduced, so that good environmental benefits, economic benefits and social benefits are obtained; according to the kitchen waste recovery treatment technology, the kitchen waste is separated into a solid phase material, an oil phase material and a water phase material in advance, then the water phase material is sequentially subjected to filtration, ultrafiltration and nanofiltration, and the water quality of discharge water reaches an integrated wastewater discharge standard; and the kitchen waste recovery treatment technology is stable in treatment effect, and pollutants are removed completely.
Description
technical field [0001] The invention belongs to the technical field of resource recovery and recycling treatment, and in particular relates to a kitchen waste recovery and treatment process. Background technique [0002] Kitchen waste is the most common waste produced in urban daily life. It belongs to urban domestic waste. Its main components include organic matter such as starchy food, plant fiber, animal protein and fat. It has high water content, high oil and salt content. High, perishable and smelly, not conducive to the transportation of ordinary garbage trucks. If this kind of garbage is not treated by classification and special treatment, it will cause great harm to the environment. [0003] Food waste mainly comes from food processing leftovers (kitchen waste) and food residues (swill) produced by the catering service industry, households, canteens of enterprises and institutions, etc. [0004] Food waste contains a lot of organic matter, which has certain utiliza...
