Embodiment 1
[0031] combine Figure 1 to Figure 4 As shown, this embodiment provides a desulfurization wastewater clarification system, including a pool body 1, an electroflocculation assembly, and a sloping plate assembly disposed inside the pool body 1. The sloping plate assembly includes a plurality of sloping plates 2 arranged at intervals and inclined. The electrocoagulation assembly includes a plurality of electrode plates 3 and a power supply 4 for supplying power to the plurality of electrode plates 3 , and each electrode plate 3 is detachably installed on a slant plate 2 .
[0032] Such as figure 1 As shown, the desulfurization wastewater clarification system of this embodiment also includes a guide rail 5 and a hoisting device 6 slidingly arranged on the guide rail 5, and the hoisting device 6 is connected with the swash plate assembly through a connecting piece 7; wherein, the hoisting device 6 is the In the field of light and small lifting equipment, the wire rope or chain is ...
Embodiment 2
[0047] This embodiment provides a desulfurization wastewater treatment method, using the desulfurization wastewater clarification system in Example 1 to perform electrocoagulation treatment on the desulfurization wastewater; wherein, the F in the desulfurization wastewater - The concentration is 70mg / L, the concentration of suspended matter is 350mg / L, and the content of 10-50μm particles in the suspended matter is 64.13%.
[0048] The conditions of electrocoagulation treatment are: current density 15mA / cm 2 , processing time 90min.
[0049] After testing, F in desulfurization wastewater - Concentration dropped from 70mg / L to 4.35mg / L, F - The removal rate reached 93.78%; the concentration of suspended solids dropped from 350mg / L to 40mg / L, and the removal rate of suspended solids reached 88.57%; the concentration of 10-50μm particles in suspended solids dropped from 227mg / L to 46mg / L, fine The removal rate of suspended matter reaches 79.74%.
Embodiment 3
[0051] This embodiment provides a desulfurization wastewater treatment method, wherein:
[0052] The desulfurization wastewater to be treated is as follows: suspended matter is 65425mg / L, COD is 680mg / L, BOD 5 3.3mg / L, heavy metal zinc 5.00mg / L, lead 0.25mg / L, copper 0.36mg / L, nickel 0.5mg / L, chromium 0.49mg / L, soluble fluorine 56mg / L, The content of 10-50μm particles in the suspension is 42526mg / L.
[0053] The desulfurization wastewater treatment agent includes: the first component: about 500 mesh Fe 3 o 4 Magnetic material; second component: flocculant polyaluminum chloride (PAC); third component: coagulant polyacrylamide (PAM); wherein, the first component, the second component and the third component The mass ratio between them is 200:100:2.
[0054] The steps of the desulfurization wastewater treatment method of the present embodiment are as follows:
[0055] 1) Add about 500 mesh Fe to 1L of desulfurization wastewater to be treated 3 o 4 0.2g of magnetic material...
