Buried domestic sewage treatment biological contact oxidation method

The buried sewage treatment equipment is a modular high-efficiency sewage biological treatment equipment. It is a sewage biological treatment system that uses biofilm as the main body of purification. It fully utilizes biofilm reactors such as anaerobic biological filter and contact oxidation bed. It has the characteristics of large biological density, strong dirt resistance, low power consumption, stable operation and convenient maintenance. At present, the integrated device has a wide application prospect.

Biological contact oxidation

The biological contact oxidation method is a wastewater biological treatment method derived from the biofilm method, that is, a biological contact oxidation tank is filled with a certain amount of filler (elastic three-dimensional filler), and the biofilm attached to the filler and the fully supplied oxygen are used. Biological oxidation, oxidative decomposition of organic matter in wastewater, to achieve purification purposes. It has the advantages of activated sludge method and biofilm method combined with the advantages of activated sludge method and biofilm method. Under the biochemical conditions, no matter whether it is applied to industrial wastewater or aquaculture sewage or domestic sewage treatment, good economic benefits have been achieved. The process is widely used in sewage treatment systems of various industries due to its characteristics of high efficiency, energy saving, small footprint, impact load resistance and convenient operation and management.

The domestic sewage (via septic tank) from the inflow into the fine grid pool to remove large particles can sink solids and suspended solids in water and then flow into the conditioning tank. Regulating the effluent into the biological contact oxidation pond in the biological contact oxidation pond pool filled with soft filler aeration wastewater flowing through the packing layer to make the surface of the filler overgrown with biofilm to increase micro-power, that is, a small blower blasting the sewage under aerobic conditions and biofilm full The microorganisms in contact with the sewage gradually oxidize the organic matter remaining in the sewage into carbon dioxide, water and cell material sewage to be purified. At the same time, the dissolved oxygen level is controlled to ensure that the ammonia nitrogen in the sewage is converted from nitrated bacteria to nitrate nitrogen. The effluent is separated into solid and liquid by the sedimentation tank, and then introduced into the filter tank to be filled with hard-filled quartz sand, and the effluent from the sedimentation tank is further adsorbed and precipitated to meet the discharge requirements. After the zui sewage flows into the disinfection tank, the chlorine dioxide is used to disinfect the water to reach the standard discharge.

Advantages of buried domestic sewage equipment:

Buried domestic sewage treatment technology The biological contact oxidation process has the characteristics of small footprint, not easy to damage the landscape characteristics of the surrounding community and the landscape of the buried area. At the same time, the buried sewage device can also bring noise and odor to the residents of the residential area. The impact is reduced to zui low. The buried biological contact oxidation process applies micro-power enthalpy to change the state of insufficient oxygen supply and insufficient biological activity of the sewage treatment device to increase the removal rate of pollutants. The micro-power aeration tank unit is a modular structure, which can better meet the requirements of the phased construction of the sewage treatment station plant.
