Embodiment 1
[0053] In this example, using figure 1 Processing device shown.
[0054] The farmhouse catering wastewater collected through the pipe network flows into the oil separation sedimentation tank 1 by itself, and the suspended solids and oil in the sewage are initially separated by natural flotation, so as to prevent it from clogging the subsequent treatment unit and reduce the load of subsequent treatment, and then pass through The pretreated sewage enters the aerobic tank 2, and a combined film-hanging filler is set in the aerobic tank, and microorganisms are inoculated. The growth provides strong conditions and increases its contact area with the sewage. The bottom of the oxidation tank filler is directly blown and aerated, and the biofilm is directly strongly disturbed by the updraft, which renews quickly and maintains a high activity. At the same time, the influent load is stable. Under certain circumstances, the biofilm can maintain a certain thickness and is not prone to cl...
