Description

technical field [0001] The invention relates to the technical field of ozone treatment in water treatment, in particular to an evaluation system and method for ozone water treatment technology. Background technique [0002] Ozone is a highly oxidizing gas that has been widely used in advanced sewage treatment. Ozone mainly plays the role of decolorization, sterilization and oxidation in sewage treatment. In addition, ozone can generate active hydroxyl radicals through catalyst catalysis. Ozone And free radicals can break the macromolecular organic matter in water into small molecular organic matter or directly mineralize. Therefore, ozone is widely used in water and sewage treatment. [0003] However, ozone is very unstable and decomposes slowly at room temperature, and if pollutants are added to the reactor, the pollutants will deplete the ozone, and the unreacted ozone will leave the system with the tail gas, and there will be some dissolved parts in the water ozone.

Problems solved by technology

[0003] However, ozone is very unstable and decomposes slowly at room temperature, and if pollutants are added to the reactor, the pollutants will deplete the ozone, and the unreacted ozone will leave the system with the tail gas, and there will be some dissolved parts in the water ozone

Ozone's instability and multi-phase characteristics make its accurate detection difficult, the cost of detection and evaluation is high, and the determination of its reaction kinetics is easy to deviate from the real situation

This makes it impossible for the design of the ozone process to select appropriate design parameters based on a variety of actual water quality, which brings uncertainty to the process effect and operating cost
