Examples
Embodiment 1
[0062] An exchange electrode electroosmosis sludge dewatering method based on voltage classification detection. Two sets of experiments were carried out for comparison. The first group used traditional electroosmosis technology, and the second group used exchange electrode electroosmosis technology. The rest of the conditions were the same. The results of the two groups of experiments were Figure 4 shown.
Embodiment 2
[0064] An exchanged electrode electroosmosis sludge dewatering method based on voltage classification detection. Three sets of experiments were carried out for comparison. The first group used traditional electroosmosis technology, and the second group used exchanged electrode electroosmosis technology combined with ammonium persulfate advanced oxidant , the third group used exchanged electrode electroosmosis technology combined with ferrous activation of ammonium persulfate oxidant, and the rest of the conditions were the same. The results of the two groups of experiments were Figure 5 shown.
Embodiment 3
[0066] An exchanged electrode electroosmosis sludge dewatering method based on voltage classification detection. Two sets of experiments were carried out for comparison. The first group used traditional electroosmosis technology, and the second group used exchanged electrode electroosmosis technology combined with ammonium persulfate advanced oxidant And take the voltage classification detection system, the rest of the conditions are the same. The results of the two groups of experiments were Figure 6 shown.
[0067] From the above three examples, it can be clearly concluded that the second group in Example 3 has the best dehydration effect. It also proves the good effect of using exchanged electrode electroosmosis technology combined with ammonium persulfate advanced oxidant and adopting voltage classification for sludge dewatering.
