hydrogen sulfide:
ammonia
Methyl mercaptan:

to explain further: sulfate radicals (SO4) are radicals with higher redox potentials and are therefore believed to oxidize most organics under ideal conditions, as detailed in the above reaction mechanism.
The surface of the silicon carbide ceramic substrate plate is of a micropore accumulation structure, and the specific surface area is very large. When the substrate plate carries an oxidizing agent to perform oxidation reaction, the surface of the substrate plate is basically free of residues. When the struvite is loaded with sodium dihydrogen phosphate and magnesium sulfate, the struvite is sensitive to humidity in the air and is collected on the surface of the substrate after a long time to form struvite;
sulfate radicals attack N bonds and H bonds and directly destroy skatole structures to form heterocyclic substances and organic weak acids;
after the reaction with the oxidation bed A3 and the oxidation bed B4, the treatment process can be completed without any auxiliary conditions except for the need of fixing the flow rate of gas in the pipeline 5, so that the treatment effect is achieved, and the oxidation bed A3 and the oxidation bed B4 can be conveniently combined, carried and transported. When the substrate plate is inactivated, the substrate plate can be prepared by the A oxidant or the B composite reactant again, so that the substrate plate can be repeatedly used, and the operation cost is reduced.
