Embodiment 1
[0046] The preparation of embodiment 1 micron magnetic separation fly ash
[0047]The fly ash is screened with a magnetic separator to screen out the high-iron fly ash, and then the high-iron fly ash is ball milled, sieved and re-magnetically separated to obtain a particle size ≤ 10 μm and an iron grade between 30-50%. Medium-magnetic high-iron fly ash: place medium-magnetic high-iron fly ash in 0.1mol / L dilute hydrochloric acid for 4 minutes, put it in an oven and dry it at 110°C for 24 hours to obtain micron-sized magnetically separated fly ash.
[0048] The electron microscope picture (9000 times) of the prepared micron-scale magnetic separation fly ash is as follows figure 1 shown. figure 1 The data show that the prepared micron-scale magnetic separation fly ash is oval, with a diameter of 80-100um and a specific surface area of 9.7m 2 / g, the iron element content reaches 53.2%, and the main valence form is Fe 3 o 4 .
Embodiment 2
[0049] The preparation of embodiment 2 magnetic sludge charcoal
[0050] Step 1, centrifuge the Fenton sludge at 4000r / min for 8 minutes to remove excess water, then freeze-dry the centrifuged sludge at 8°C to obtain the sludge carbon precursor;
[0051] Step 2, put the sludge carbon precursor in the tube furnace, with N 2 As a protective gas, heat to 600°C, keep the temperature constant for 3 hours, and obtain magnetic sludge charcoal after cooling.
[0052] The electron micrograph (4000 times) of the prepared magnetic sludge charcoal is as follows figure 2 shown. Depend on figure 2 It can be seen that the surface of the magnetic sludge carbon is rough, with multi-level pores evenly distributed, iron oxides embedded in the carbon material, the iron content reaches 15.2%, the structure is stable, and the specific surface area reaches 109.7m 2 / g, which is conducive to the high adsorption and concentration of microorganisms and pollutants.
Embodiment 3
[0053] Embodiment 3 sewage treatment system
[0054] sewage treatment systems such as image 3 As shown, it specifically includes: water inlet pump 1, anaerobic reaction zone 2, three-phase separator 3, microporous aeration head 4, micro-oxygen reaction zone 5, water outlet pump 6, backwashing device 7, and backwashing outlet 8; Wherein, the anaerobic reaction zone 2 is an anaerobic reaction processor (UASB), and the microaerobic reaction zone 5 is an aerated biofilter, and the aerated biological filter is provided with 6 aeration heads; the anaerobic reaction zone filler is an embodiment The micron-scale magnetic separation fly ash prepared in 1, the micro-aerobic reaction zone filler is the magnetic sludge charcoal prepared in Example 2.
