Description

The near-zero release processing system and method for a kind of high concentrated organic wastewater and sludge
Technical field
The invention belongs to chemical industry and environmental technology field, and in particular to a kind of height using supercritical Water Oxidation Technology as core The near-zero release processing system and method for concentration organic wastewater and sludge.
Background technology
Under normal conditions, water exists with steam, liquid water and the common state of three kinds of ice, and liquid water is polar solvent, its Density changes little with the rise of pressure, can dissolve most of electrolyte including salt, to gas and most of Organic matter then slightly soluble or insoluble.Supercritical water refers to that temperature, pressure are above the spy of its critical point (374.15 DEG C, 22.1MPa) Water under different state.The property of supercritical water can occur greatly to change, its density, dielectric constant, diffusion coefficient and thermal conductivity Rate is all different from light water.Moreover, the solubility of organic matter and gas in supercritical water significantly improves.
Supercritical Water Oxidation Technology (SCWO technologies) is exactly that make use of water possessed special nature in the supercritical state, Oxidant and organic matter is set to be dissolved completely in supercritical water and homogeneous oxidation reaction occurs, rapidly, thoroughly by organic matter It is converted into the micromolecular compounds such as harmless carbon dioxide, nitrogen and water.Traditional highly difficult, bio-refractory have with other The treatment technology of machine waste water is compared, and supercritical Water Oxidation Technology has the advantage that：
1st, oxidation efficiency is high, and the theoretical removal rate of organic matter is up to more than 99.9%；
2nd, the reaction time is short, and device structure is simple, and floor space is small；
3rd, after organic matter mass concentration reaches 3%, system can realize self-heating.
Supercritical Water Oxidation Technology has at home and abroad been applied, but when process object is petrochemical sludge, still There are the problem of several respects to need to solve, and is mainly manifested in：
Although theoretically seeing, the COD removal rates that can make organic wastewater (sludge) using SCWO technologies are up to 99.9%, But this data is realized under very good reaction environment, including higher coefficient of oxidation (3~10 times), higher is anti- Answer condition (600~700 DEG C, 27~29MPa), longer reaction time (100~150s).Like this, system pipeline Selection, the quantity delivered of oxygen and the size of reactor will improve, this needs high raising to be realized into original, SCWO skills The economy of art treated sewage will have a greatly reduced quality.Therefore need to aid in SCWO technical finesses by other sewage disposal means.
Contain the organic matter of more easy coking in sludge, if be fed by traditional method using heating furnace to sludge Preheated, the extreme temperatures of pipe heating, the organic matter in water-containing sludge has higher coking tendency on high-temperature wall surface.Such as Fruit monitors not in time, and wall occurs coking and causes wall temperature to ascend to heaven, and causes to block in wall overtemperature tube burst or pipe.
When the treating capacity of sludge is larger, whole system flow is longer, if reactor inlet temperature deficiency needs to mend temperature, If heated using gas-fired heater, heating amount is unable to control.If using electric furnace, it is electrically heated startup the time compared with Long, thermal inertia is strong, can not realize quick concurrent heating.Therefore a kind of device that can control heating power quick concurrent heating at the same time is needed.
SCWO processes are an exothermal reaction process, and studies have shown that after organic matter mass concentration reaches 3%, put by reaction The heat gone out preheats the material into before reactor enough.But since SCWO reactions are that high temperature, high pressure, a hyperoxia contain The strong corrosive environment of amount, it is high for the equipment choice requirement in system, nickel-base alloy is typically chosen as cores such as reactors The material of equipment, the higher price of nickel-base alloy, many materials even not yet realize throwing in advance that is domestic, therefore can causing higher Money.
