Background
The existing catalytic oxidation process is mainly based on a spray tower structure, and when the concentration of inlet air is high, organic matters decomposed by a compound oxidant are dissolved in spray liquid, so that the concentration of the spray liquid is high. When the catalytic oxidation decomposition is continued, the oxidation effect is poor, and organic matters in the circulating liquid can bring out a part of pollutants, so that the outlet exceeds the standard. Original oxidation tower has the risk that exceeds standard when meetting the higher tail gas of concentration, and main one water tank of sharing when original, the circulating liquid uses mixedly, and the circulating liquid concentration of the superiors all can be higher than tail gas pollutant concentration, when blowing on tail gas, takes out the circulating liquid, leads to tail gas to exceed standard.
