Embodiment 1
[0023] Example 1: What this embodiment adopts is the activated sludge process and its improved process. The volume ratio of each reactor is aeration tank:secondary sedimentation tank:magnetization tank=20:8:1. The concentration of sludge in the aeration tank is 1-3g / l, the temperature in the aeration tank is kept at 20-40 degrees, the pH is kept at 6.8-7.5, and trace elements calcium, iron, magnesium, and cobalt are added to the aeration tank , Nickel, the addition amount is 0.08 mg / l, 0.08 mg / l, 0.08 mg / l, 0.04 mg / l, 0.04mg / l respectively, so that the concentration of trace elements iron, manganese, calcium, magnesium and sodium are kept at A certain concentration, the magnetic field strength of the magnetization pool is 50GS. There are 3 sets of experimental devices (marked as a, b, c). The three sets of devices are all connected to the activated sludge of the secondary settling tank of a sewage treatment plant, and the untreated sewage (COD is 250mg / l) is fed into the ...
