Embodiment 1
[0055] 1. Squeeze, crush, and dehydrate the food waste to obtain solid-phase and liquid-phase materials, and then recycle the solid-phase food waste and liquid-phase food waste respectively.
[0056] 2. Disposal of food waste in solid phase:
[0057] 1) Evenly mix the food waste solid phase with rice straw at a weight ratio of 9:1, and then mix it with the bacterial liquid at a mass-volume ratio of 100:1, and then transfer it to a fermentation reactor. Wherein, the moisture content of the mixed material after mixing the bacterial solution is 75%, the moisture content of the straw is 15%, and the length of the straw is 8cm, and the materials are all from Zhejiang.
[0058] 2) The start-up warehouse adopts intermittent aeration and ventilation at the bottom. 30 minutes is an aeration and ventilation cycle. In each cycle, it is opened for 15 minutes and closed for 15 minutes. The aeration and ventilation rate is 1.4L / min per kilogram of material, and the temperature is 40°C.

Abstract
The invention discloses a kitchen waste solid-liquid two-phase resource total recovery treatment method and system. The method comprises the following steps: carrying out solid-liquid separation on the kitchen waste to obtain a solid-phase substance and a liquid-phase substance; auxiliary materials and a microbial agent are added into the solid-phase matter for substrate adjustment, a mixed solution is obtained, the mixed solution is sent into a fermentation reactor, aeration aerobic fermentation is conducted under the heating condition, and the organic fertilizer is obtained; and removing grease in the liquid-phase substance, feeding the grease-removed liquid-phase substance into a fluidized bed reactor, adding a magnesium ion-containing solution and an induction carrier into the fluidized bed reactor, and carrying out an induced crystallization reaction to obtain struvite crystals after the reaction. The kitchen waste is treated in a manner of coupling aerobic fermentation and struvite precipitation, the aim of fully recycling resources is achieved, and the method has the advantages of being short in treatment period, high in treatment efficiency and the like.
Description
technical field [0001] The invention belongs to the field of environmental protection, relates to the technical field of harmless treatment and resource utilization of organic solid waste resources, and in particular relates to a method and system for full recovery and treatment of solid-liquid two-phase resources of kitchen waste. Background technique [0002] Resource recovery is of great ecological strategic value. At present, the discharge of organic waste is increasing at an average annual rate of 5% to 10%, and its types and quantities have also increased sharply, causing pressure on the ecological environment. However, these solid wastes contain a large amount of organic matter. Under the current situation, developing organic solid waste resources, turning harm into profit, and turning waste into treasure can not only reduce the pollution of waste to the environment, but also realize the recycling of waste, and realize the "harmless, reduced, It will be an ideal choi...
