Example Embodiment
[0026] Example 1
[0027] like figure 1 As shown, it is an electric flocculation-fiber filtration water treatment device, including a reaction tank body 1, a water inlet 2 is provided at the bottom of one side of the reaction tank body 1, and a pool is provided at the top of the opposite side of the reaction tank body 1 and the water inlet 2 Body water outlet 3, the interior of the reaction tank body 1 is provided with an anode and a cathode, the anode includes a first anode plate 4 and a second anode plate 5, and the cathode is composed of a central filter body 6 and a carbon fiber filament 7 wound around the central filter body 6. Conductive carbon fiber filter cathode, wherein the first anode plate 4 and the second anode plate 5 are located upstream of the water flow, and can be connected to the positive electrode of the DC power supply 10 through the anode wire 8, and the carbon fiber filter cathode is located in the water flow downstream, and can pass through the cathode ...
Example Embodiment
[0042] Example 2:
[0043] Adopt the electro-flocculation-fiber filtration water treatment device of embodiment 1 to process acid orange 7 simulated dye waste water, and the acid orange 7 concentration of the pollutant to be treated is 20mg / L:
[0044] Control reaction parameters: adjust the initial pH of wastewater to 6-8 and the current density to 90A / m 2 , the control flocculation reaction time is 30min;
[0045] Treatment process: After adjusting the pH of the wastewater, pass it into the reaction tank 1, turn on the stirring device 11, then start the DC power supply 10, and set the system voltage or current according to the requirements. After the flocculation reaction has passed for a period of time, the peristaltic pump is used to extract the wastewater at a constant speed. Filtration was carried out using a fiber filter cathode, and the effluent was collected.
[0046] Treatment results: After many tests, the average removal rate of acid orange 7 was over 95%, and th...
Example Embodiment
[0047] Example 3
[0048] Adopt the electroflocculation-fiber filtration water treatment device of embodiment 1 to process methylene blue simulated dye waste water, and the methylene blue concentration of the pollutant to be treated is 20mg / L;
[0049] Control reaction parameters: adjust the initial pH of the wastewater to be 9, and the current density to be 110A / m 2 , the control flocculation reaction time is 30min;
[0050] Treatment process: the same as in Example 2;
[0051] Treatment results: With the progress of the electro-flocculation process, the wastewater in the reaction tank 1 changed from blue to dark green, reddish-brown, and black-brown in turn. The lower anode 4 produced floccules, and the cathode had bubbles escaping. The color of the effluent is close to transparent; after testing, the removal rate of methylene blue in the effluent reaches 96.70%.
