Embodiment Construction

[0014] In conjunction with the process flow chart, the embodiments are described in detail.

[0015] Domestic garbage is sorted; specifically, screening, combined with winnowing, the available resources are recycled. The purity of the sorted organic waste is more than 95%, and it is put into the storage tank. Then it is sent to the chemical catalytic degradation tank through a large inclination conveyor; at the same time, the catalyst is added. The catalyst is based on one ton of concentrated sulfuric acid (98%), mixed with five tons of phosphate rock powder (containing P 2 o 530% or more). The addition amount is 20% of the pure organic matter, and the catalyst is the free sulfuric acid produced in the reaction process and the released phosphoric acid. After the material is full, open the electric control valve of the boiler's high-temperature and high-pressure steam, and let superheated steam flow in. The temperature is 250°C, the pressure is 1.4MPa, and the reaction time...

Abstract

A process for chemically stabilizing the life garbage includes such steps as quickly degradating the organic high-molecular compound containing C and N to become micro moleculae, and Maillard reaction to generate micro-molecular C-N compound to be used as fertilizer.

Description

[0001] The invention discloses a chemical stabilization treatment technology for household garbage Technical field: [0002] The invention belongs to the field of organic solid waste treatment and comprehensive utilization Background technique: [0003] At present, at home and abroad, the long-term composting fermentation method is adopted for the stabilization of organic solid waste such as domestic garbage, and the time is 20-30 days; although the result has achieved the stabilization in the traditional sense, no secondary fermentation It produces heat and kills a large number of insect eggs and pathogenic bacteria; but the negative effect is also obvious; due to long-term composting and fermentation, a large amount of greenhouse gases and volatile toxic and harmful gases are produced; especially malodorous gases, the pollution of the environment is very serious , attract mosquitoes and flies to parasitize, and easily produce epidemic infectious diseases. Due to long-term...
