Embodiment Construction
[0022] The invention relates to a system for incinerating high-salt organic waste water. The system of the present invention includes an incinerator, and a molten inorganic salt discharge device fluidly connected with the incinerator.
[0023] The incinerator used in the system of the present invention is not particularly limited, and may be any incinerator known in the art for incinerating high-salt organic wastewater. In an example of the present invention, the salt-containing organic wastewater treatment device disclosed in CN201688420U is used, and the device includes a salt outlet 12 .
[0024] In the present invention, the term "high-salt organic wastewater" refers to wastewater with a total salt content of at least 1% and organic matter, which mainly comes from chemical plants and oil and natural gas collection and processing. This wastewater contains a variety of substances such as salt, oil, organic heavy metals and radioactive substances, among others. The organic ...

Description
technical field [0001] The invention relates to a treatment method for high-salt organic wastewater. More specifically, the present invention relates to a method for discharging molten salt produced in a high-salt organic wastewater incineration system. The method of the invention is easy to operate, has strong universality and low cost, and can advantageously prolong the operation period of the equipment. Background technique [0002] High-salt organic wastewater mainly comes from the production processes of fine chemicals, medicine, printing and dyeing, papermaking, and pesticides. It also includes concentrated brine produced by other wastewater treatment processes such as nanofiltration, reverse osmosis, electrodialysis, and evaporation concentration. In the prior art, a variety of treatment methods for high-salt organic wastewater have been proposed, including biological methods, membrane separation methods, electrochemical methods, wet catalytic oxidation methods, inci...
