[0002] In recent years, the nanofiltration process has gradually become the mainstream process in sewage regeneration treatment and landfill leachate treatment. Although the effluent water quality is good, the nanofiltration system will produce 20%~30% of the concentrate
In the prior art, the refractory organic matter in nanofiltration and reverse osmosis concentrated liquid contains a large amount of humus and hardness ions, which has worse biodegradability, higher salt content, and more difficult treatment, so it needs to be properly treated

Embodiment Construction
[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0024] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a strong oxidization treatment process for nanofiltration concentrated liquor. The process includes: precipitating or settling the nanofiltration concentrated liquor; performing catalytic ozonation treatment; regulating water pH; performing high-speed turbulent flow biological treatment to remove residual total nitrogen; performing strong oxidization treatment; recycling tail gas; performing solid-liquid separation. The strong oxidization treatment process has the advantages that the process is high in efficiency, fast, thorough in oxidation and the like, the biotoxicity of the concentrated liquor is lowered greatly, refractory organics can be effectively degraded, and normal and stable operation of a whole treatment system is guaranteed.
Description
technical field [0001] The invention relates to the technical field of nanofiltration concentrated liquid treatment, in particular to a strong oxidation treatment process for nanofiltration concentrated liquid. Background technique [0002] In recent years, the nanofiltration process has gradually become the mainstream process in sewage regeneration treatment and landfill leachate treatment. Although the effluent water quality is good, the nanofiltration system will produce 20%~30% concentrate. In the prior art, the refractory organic matter in nanofiltration and reverse osmosis concentrates contains a large amount of humus and hardness ions, which has worse biodegradability, higher salinity, and more difficult treatment, so proper treatment is required. Contents of the invention [0003] In order to overcome the above shortcomings and deficiencies, the purpose of the present invention is to provide a strong oxidation treatment process for nanofiltration concentrated liqui...
