1. Experimental principles and purposes:

ABF's process process, a tower filter is set before the usual activated sludge process. It can be connected in series or connect with the aeration tank, but it is m--nly connected in series. There are many active sludge attached to the surface of the tower filter filter material, so the material of the filter material uses a polypropylene ball, ø40 ～ ø50, the porosity rate between the balls, the natural ventilation, and the biofilm when the biological membrane falls off at the age The filter bed is not easy to block. In the project, the tower is generally 4-6m high. The design load rate of the tower is 3.2kg/m3 ・ d, and the removal rate is about 65 %. The effect of treatment in winter is poor, which is related to water temperature. The outflow of the tower is as high as 6 to 8 mg/L (20 ° C), and the hypoxic fluid requires a high oxygen rate. As the concentration of wastewater is different, it can reach about 30 to 300mg/L ・ H.

The filter here uses a blanket (can also be exposed). The tower is a strong oxygen. Therefore, ABF can be regarded as a composite active sludge method.

The time of the sewage flow filter is less than 1min, but due to the existence of the pendant water of the filter material sludge layer, the staying time of the sewage is actually much longer.

Through the "ABF process" experiment, I hope to achieve the following purpose:

1. Master the basic operation process of the active biological filter "ABF process";

2. Deepen the principle of understanding the experiment;
