The main equipment of this system is mainly composed of wastewater mixing system, thermal oxidation system, waste heat recovery system, tail gas post-treatment system and induced draft fan. The waste liquid is atomized by the injection equipment and then injected into the oxidizer, where it is mixed with air in the form of droplets and burned. The temperature of the combustion chamber is controlled above 800°C to gasify and decompose the waste liquid. This system adopts the most advanced treatment process at present, which can not only treat pollutants with high efficiency, but also achieve the greatest energy-saving effect.
