## 3 Results and Discussion
A spray wet scrubber was installed to absorb SO\({}_{2}\) and other acidic pollutants effectively. To satisfy the increasingly stringent emission standards, some adjustments to the treatment methods must be made regularly, including mechanical add-ons, activated carbon injection to adsorb heavy metals and organic pollutants, a wet scrubbing tower, and ultra-fine atomization through venturi pump technology to further eliminate SO\({}_{2}\) and PM2.5 [33]. Finally, an end-of-pipe treatment device will again be added to further remove mercury, SO\({}_{3}\), sulfuric acid, aerosols, and PM2.5 among other pollutants to satisfy the expected arrival of even stricter emission standards [8; 34; 35]. The catalytic mechanism of ozone deep oxidation into gaseous pollutants was also proposed. In short, the reaction rate of gaseous pollutants to ozone, the key rate-determined step, will be accelerated by more active oxygen radicals with the help of ozone decomposition acceleration by metal ion valance cycles. The reactants' adsorption is the initial steps. It has been confirmed that the presence of ozone enhances the catalyst adsorption capacity [8], the dominant adsorbed form of nitrogen oxides on the catalyst surface. With the increasing valance of nitrogen oxides, the adsorption capacity was improved, and it significantly increased [8]. The concentration and emission of CO decreases with the increasing ratio of the ozone concentration in air, and the process is enhanced when the thermal power of the third combustion chamber is enlarged [36; 37]. To ensure safe and robust treatment, it is vital to define the ozone demand and ozone kinetics to avoid as much variety in the outcomes as possible. The residual ozone will be separated into 2 parts.

The second part will be mixed with water in a tank then the mixed ozone will be fed to a wet scrubber room in order to treat exhaust gas in a wet scrubber room. After the treatment, the mixed ozone will flow out to a pond and it will be used in the treatment system repeatedly. This is called a recirculation system. Experiments were performed to investigate the ozone kinetics and demand and to evaluate the effects on the air and water quality of the treatment systems [38]. In particular, the water quality parameters were measured, and the organic compound concentration changes during ozonation in the wet scrubber room were monitored and recorded [39]. The ozone reactions were described through kinetics, as they provided a better understanding of the ozone decay mechanisms, particularly the speciation forms of Cd, Pb, and Hg in the exhaust gas, that could be used to define further safe ozone treatment margins in the next steps [25; 40].
