Kitchen waste treatment process

Abstract

The invention discloses a kitchen waste treatment process. The kitchen waste treatment process comprises the following steps of conveying kitchen waste into a pre-treatment system for screening, pulping and heating; conveying the kitchen waste treated by the pre-treatment system to a recycling system for three-phase separation, to obtain crude oil, residues and waste water; processing and recycling the crude oil and residues in the recycling system, and leading wastewater to enter an anaerobic reactor through the pre-treatment system; conveying marsh gas generated by the anaerobic reactor to an energy recovery system, and conveying the wastewater and floating oil generated by the anaerobic reactor to a post-treatment system; and purifying and discharging the generated wastewater through the post-treatment system, and returning activated sludge generated by the post-treatment system to the recycling system. According to the kitchen waste treatment process, energy and resources in the waste can be fully utilized, the kitchen waste is harmlessly treated after the resources are utilized, and the whole process is environmentally friendly, clean and easy to use.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a kitchen waste treatment process. Background technique [0002] With the continuous development of the economy, people's living standards continue to improve; in the era of increasing food and non-staple food, the kitchen waste composed of kitchen residues and post-meal residues is increasing day by day. Randomly discarded food waste not only rots and smells, breeds mosquitoes and flies, spreads diseases, but also pollutes the environment, so it has gradually become a source of pollution that cannot be ignored; its treatment has also received increasing attention. However, the amount of food waste in my country is very large, and it is showing a rapid upward trend. With the continuous acceleration of the urbanization process, the environmental and ecological problems caused by food waste are becoming more and more significant. However, food waste contains a lar...
