Embodiment 1
[0039] Experimental group: configuration containing 4-chlorophenol concentration of 50mg L -1 Simulated waste water was treated in the device of the present invention for 40 minutes. The specific operating parameters and processing effects are as follows: the ultrasonic input power is 80W, and the ultrasonic frequency is 25kHz. The operating voltage of the regulated power supply is 1V, and the current density is 0.85mA cm -2 . In order to improve the conductivity, the sewage treatment tank contains an inert electrolyte Na 2 SO 4 , whose concentration is 0.05mol L -1 . The anode material chooses conductive ceramic material titanium suboxide active film electrode (length 7.7cm, inner diameter 2.3cm, length 2.8cm), the cathode material chooses stainless steel mesh (length 55cm, height 7.5cm, wire diameter 1mm, aperture 2.63mm), and the reference Electrode selection Ag / AgCl electrode (0.195V vs SHE). The wire material is copper wire. The anode is located in the center of t...
