Embodiment 1
[0033] The sludge to be dewatered is collected from a sewage treatment plant in Beijing, which uses the traditional activated sludge process to treat municipal sewage. The activated sludge collection point is located somewhere on the return path from the secondary sedimentation tank to the aeration tank. The sludge concentration (MLSS) reached 6.87g / L, the moisture content was 99.29%, and the pH value was 7.34.
[0034] 1) Place the activated sludge in a horizontal pressurized electric field reactor;
[0035] 2) Accurately weigh the magnetic material of 300g / kg of dry sludge, quickly put the magnetic material into the sludge at a stirring intensity of 750 rpm / min, stir for 30 seconds, and then stir for 25 minutes at 50 rpm / min;
[0036] 3) Connect the negative and positive poles of the reactor to the negative and positive poles of the power supply, and adjust the voltage to a constant 40V. Connect the pressure control device and set the pressure value to 100kPa. Turn on the p...

[0039] The sludge to be dewatered is collected from a sewage treatment plant in Beijing, which uses the traditional activated sludge process to treat municipal sewage. The activated sludge collection point is located somewhere on the return path from the secondary sedimentation tank to the aeration tank. The sludge concentration (MLSS) reached 6.20g / L, the moisture content was 99.36%, and the pH value was 7.44.
[0040] 1) Place the activated sludge in a horizontal pressurized electric field reactor;
[0041] 2) Accurately weigh the magnetic material of 300g / kg of dry sludge, quickly put the magnetic material into the sludge at a stirring intensity of 900rpm / min, stir for 30s, and then stir for 25min at 50rpm / min;
[0042] 3) Connect the negative and positive poles of the reactor to the negative and positive poles of the power supply, and adjust the voltage to a constant 40V. Connect the pressure control device and set the pressure value to 300kPa. Turn on the power switch ...

[0045] The sludge to be dewatered is collected from a sewage treatment plant in Beijing, which uses the traditional activated sludge process to treat municipal sewage. The activated sludge collection point is located somewhere on the return path from the secondary sedimentation tank to the aeration tank. The sludge concentration (MLSS) reached 6.37g / L, the moisture content was 99.42%, and the pH value was 7.38.
[0046] 1) Place the activated sludge in a horizontal pressurized electric field reactor;
[0047] 2) Accurately weigh the magnetic material of 150g / kg of dry sludge, quickly put the magnetic material into the sludge at a stirring intensity of 900rpm / min, stir for 30s, and then stir for 25min at 100rpm / min;
[0048] 3) Connect the negative and positive poles of the reactor to the negative and positive poles of the power supply, and adjust the voltage to a constant 50V. Connect the pressure control device and set the pressure value to 300kPa. Turn on the power switch...
