Abstract

The invention relates to the technical field of resource and environment, in particular to a supercritical water oxidation system and a starting method thereof. The system comprises a fuel branch, evaporable water branches, a waste liquid branch, an oxygen branch, a water membrane reactor and a mixer; the fuel branch and the waste liquid branch are respectively connected to the mixer, and the mixer is connected with a raw material inlet of the water membrane reactor; the evaporable water branches are respectively connected to a raw material inlet and a side wall surface of the water membrane reactor, and the oxygen branch is connected with an oxygen inlet of the water membrane reactor. The supercritical water oxidation system adopts the fuel as a starting simulation material to start the supercritical water oxidation reaction of the simulation material, thereby achieving an effect for warming a furnace; then the real waste liquid is gradually used to substitute the fuel, so that the waste liquid can be directly injected into the reactor without being preheated.

Description

Technical field [0001] The invention relates to the technical field of resources and environment, in particular to a supercritical water oxidation system and a starting method thereof. Background technique [0002] High concentration (chemical oxygen demand COD> 2000mg / L), the treatment of toxic and refractory organic wastewater is a technical problem recognized at home and abroad. Traditional organic wastewater treatment technologies (such as physical and chemical treatment technology, biological treatment technology, wet oxidation, incineration, etc.) have problems such as high cost, low degradation rate, and secondary pollution. Supercritical Water Oxidation (SCWO), as a new type of organic wastewater treatment technology, is one of the effective methods to solve this problem. [0003] Supercritical water oxidation is a method of "burning" and oxidizing organic matter with air or other oxidants under high temperature and high pressure conditions exceeding the critical point ...
