Review of Urban Sewage Treatment Industry in 2022 and Development Prospects for 2023
The future development of the industry has prepared policy reserves, and under the promotion of these new policies, more market demand has been released, promoting the industry to gradually enter a new stage of high-quality development.
Zhiwei environmental protection ozone catalytic advanced oxidation mainly includes two parts: efficient ozone dissolved gas system and efficient catalytic system.
(1) Principle of high efficiency ozone dissolved gas system
The electromagnetic shear principle adopted by this technology is the first technology applied in sewage treatment at home and abroad. Through the effect of electromagnetic (EM) shear field, the cluster structure of water molecules, organic pollutant molecules and ionic atmosphere in sewage is changed, and the physical, chemical and molecular mechanical properties of treated sewage are changed, and the purpose of increasing the ozone dissolution ability and improving the catalytic oxidation efficiency of ozone is achieved.
The effect of the cluster structure of water molecules under the action of EM:
2) Principle of efficient catalytic system
High efficiency and high efficiency catalytic system, divided into homogeneous catalysis and heterogeneous catalysis two kinds.
1) Reaction mechanism of homogeneous catalysis:
① Metal ions promote ozone decomposition, generate ·OH, and use highly active ·OH to oxidize organic matter;
② Metal ions and organic compounds are complexed and then eventually oxidized by ozone.
2) Advantages of homogeneous catalysis:
① is not limited by the process, can be flexibly switched according to different use scenarios, continuous or intermittent operation can be used;
② According to the different water quality, choose different materials of the plate, do not add any chemical agents;
③ Advanced micro-electrolysis technology is used to accurately control the dosage and proportion of homogeneous catalytic ions
④ The dosage is only μg/L, the catalyst loss is small, and the catalytic effect is remarkable.
