Embodiment 1

[0028] A recycling process for domestic organic waste, comprising the following steps:

[0029] (1) Domestic organic waste is collected, measured and weighed and dumped on a sorting table with a solid-liquid separator to achieve preliminary solid-liquid separation. Eliminate unprocessable non-organic substances visible to the naked eye, including porcelain, glass, and metal;

[0030] (2) The domestic organic waste after preliminary separation and sorting by the sorting table enters the horizontal conveyor belt, and the domestic organic waste is spread out on the horizontal conveyor belt, and can be sorted again to remove the non-organic matter hidden in the domestic organic waste;

[0031] (3) After the domestic organic waste passes through the horizontal conveyor belt, it enters the climbing conveyor belt. The top of the climbing conveyor belt is equipped with a spray washing device, which can reduce the oil stains and adhered metal cations on the surface of the domestic orga...

Abstract

The invention discloses a resource treatment process of domestic organic waste, which comprises (1) solid-liquid separation; (2) sorting and removing non-organic matter; (3) removing oil stains and metal cations by spraying and rinsing; (4) crushing and dehydrating, Pressing and dehydration; (5) high temperature aerobic fermentation; (6) natural secondary biological fermentation; (7) material screening; (8) water, oil and water discharged from the liquid outlet below the sorting table and the drain directly below the press dehydrator Separation; (9) remove the heavy metal ions in the organic wastewater, and then carry out aerobic fermentation to obtain a fermented liquid; (10) concentrate the fermented liquid at high temperature; (11) detect the concentrated fermented liquid; Fermentation broth is proportioned. The invention processes organic waste to obtain solid organic fertilizer, organic liquid fertilizer and oil, solves the problem of excessive heavy metals in the fertilizer, and improves the utilization rate of organic waste resources to over 95%.

Description

technical field [0001] The invention relates to a kitchen waste treatment process, in particular to a domestic organic waste resource treatment process. Background technique [0002] With the continuous improvement of urban and rural living standards and the rapid development of industrial and agricultural production levels, the discharge of urban and rural organic waste (including human organic waste, agricultural straw waste and livestock manure, etc.) is increasing day by day. According to statistics, China's annual output of urban domestic organic waste exceeds 310 million tons; the annual output of agricultural straw exceeds 650 million tons, and the annual output of livestock and poultry manure exceeds 2.6 billion tons. China has become the world's largest producer of organic waste. At present, there are three main methods of organic solid waste treatment at home and abroad: landfill, incineration and biological treatment. Landfill will cause soil pollution and high c...
