HP-Naro High pressure micro/nano ozone oxidation technology

The HP-Naro micro-nano ozone advanced treatment technology independently developed by the team can remove refractory organic matter in sewage, greatly improve the COD removal rate in coal chemical wastewater such as coking and blue carbon, and reduce the COD concentration to less than 20 mg/L in municipal wastewater in the park . The effluent COD reached the surface water environmental quality standard III water standard, achieving a technical breakthrough in this direction.

(1) High pressure dissolved gas water is formed by high pressure inlet water and Venturi jet pressurized mixture, which greatly improves the solubility of ozone and improves the solubility of ozone in water to 50-60mg/L.

(2) The high-pressure dissolved gas water is further cut in the mixing cutter and dissolved gas tank to form a large number of micro and nano dissolved gas bubbles, and then evenly distributed in the catalytic column through a special dissolved gas water release device.

HP-Naro micro-nano ozone catalytic oxidation technology greatly improves the reaction rate. Micro-nano bubbles refer to bubbles smaller than 1 micron. Compared with the large bubbles generated by traditional aeration disks, micro-nano bubbles have smaller size, larger specific surface area, slower floating speed and higher mass transfer rate. At the same time, micro-nano bubbles have the characteristics of self-contraction and rupture under the liquid, and generate hydroxyl radicals in this process, thereby improving the ability of ozone oxidation. The size effect of ozone nanobubbles is manifested as long life in liquid, surface charge, and high internal density. The unique interface properties of nanobubbles make ozone micro-nano bubbles more efficient in degrading pollutants.

Competitive advantage

td.PNG in the coal chemical industry wastewater treatment project in the COD removal rate of 50% - 60%, do not need to adding the catalyst, Solve the problem of catalyst scaling, hardening, rapid deactivation and frequent replacement;

using micro/nano bubbles, small particle size, specific surface area is big, quick reaction and mass transfer rates, the effect is good, the reactor residence time short;

high solubility of ozone, up to 50-60 mg/L, micro/nano bubbles of ozone in water long time, and can be as high as 3 hours or more;

, high utilization of ozone can be as high as 95% above, cost savings. Ozone and COD removal dosing ratio is small, ozone dosing and COD removal ratio is generally 1.5-2:1

no ozone exhaust gas overflow, only adding the ozone, adding hydrogen peroxide when necessary, no additional ions dosing, no increase in salinity, do not produce secondary pollution.

HP - Naro high-pressure micro/nano ozone catalytic oxidation technology, under the working condition of the vast majority of industrial wastewater treatment, do not need to add the catalyst.

in some rare condition, you need to add catalyst, research and development of TONRAY ozone catalytic oxidation catalyst also has strong competitive advantage in market competition.

    • 技术优势

    The surface and holes of the new catalyst can capture and enrich ozone in water, increase the local ozone concentration, and increase the conversion efficiency of ozone to hydroxyl free radicals through catalysis, greatly improve the concentration of hydroxyl free radicals, so that the reaction effect is remarkable, the reaction speed is faster, and the degradation of organic matter is more complete and thorough.

    The new catalyst monomer particle is based on activated alumina as the carrier, a variety of proprietary active components sintering, for the diameter of 3~5mm round spherical porous particles, packing density between 0.65~0.70g/cm3, it has good hydrophilic and hydraulic characteristics, so that the catalyst surface and water molecules for full contact. At the same time, interlaced airways and waterways are formed between particles to ensure better mass transfer effect.
