1.Which pollutants Cannot be removed by aeration?
The complete removal of hydrogen sulfide must be combined with pH reduction or chemical oxidation. Nonvolatile organic compounds cannot be removed by air stripping. For example, phenols and creosols are unaffected by the aeration process alone..
2.Overview:
In the sewage treatment process, in order to provide the oxygen required for the survival of microorganisms, the common biological filter generally has ventilation holes in the lower part of the filter, and relies on natural ventilation to supply oxygen, which is easy to cause uneven distribution of air pressure, short flow, local air The phenomenon of blocking, the natural ventilation and oxygen supply is subject to the difference between the temperature and the air temperature in the tank, the height of the filter tank, the gap of the filter material and the wind force, which cannot provide stable and uniform ventilation for the filter tank.
The air is forced into the layer to replace the natural ventilation and oxygen supply, so as to fully provide enough and stable oxygen required for the metabolism of microorganisms living on the ceramsite filter material to improve the overall effect of the aerated biological filter. And here plays an important role is the Disc Type Diffuser.
