    Biological turntable secondary processing flow

    Source: Author: Time: 2016-08-03 Views: Times

    The biological turntable process is an artificial enhancement of sewage irrigation and land treatment. This treatment method allows bacteria and fungal microorganisms and micro-animals such as protozoa to grow and breed on the biological turntable filler carrier to form membrane-like biological sludge --- Biofilm. The sewage is contacted with the biofilm after the primary treatment of the sedimentation tank, and the microorganisms on the biofilm take up organic pollutants in the sewage as nutrients to make the sewage purified. In the pneumatic biological turntable, dissolved oxygen required for microbial metabolism is supplied through an aeration tube provided on the lower side of the biological turntable. 污水 时,转盘表面上形成一层薄薄的水层,水层也从空气中吸收溶解氧。 The surface of the turntable is covered with an air cover. The compressed air released from the aeration tube drives the air cover to rotate the turntable. When the turntable leaves the sewage , a thin layer of water is formed on the surface of the turntable, and the water layer also absorbs and dissolves from the air. oxygen.
