Embodiment 1
[0050] see Figure 1-2 , a domestic wastewater treatment method based on electrocoagulation, comprising the following steps:
[0051] S1. Discharge the domestic wastewater to be treated uniformly into the wastewater regulating pool 1 equipped with grilles, and adjust the water quality and quantity in a targeted manner;
[0052] S2. Pump the wastewater in the wastewater regulating pool 1 into the electrolytic tank 2 through the delivery pump, and use a high-frequency high-voltage pulse power supply to energize the electrodes in the electrolytic tank 2 to electrolyze the domestic wastewater;
[0053] S3. During electrolysis, use the breathing coagulation aid assembly installed between the electrodes to continuously collect the flocs produced by electrolysis, and clean the passivation film on the electrode surfaces on both sides;
[0054] S4. Open the valve to lead the electrolyzed waste water to the aeration tank 4, use the dissolved air flotation machine to carry out the disso...
