Beneficiation wastewater treatment method circularly used for ceramic filter
A technology of ceramic filter and beneficiation wastewater, which is applied in the directions of water/sewage multi-stage treatment, neutralized water/sewage treatment, water/sludge/sewage treatment, etc. Capillary clogging, affecting the filtering effect and other problems, to achieve the effect of reducing the amount of fresh water, good water quality, and normal filtering effect

Example Embodiment
[0020] Example 1:
[0021] Based on each liter of wastewater, add 10 mg of anionic flocculant PAM, 60 mg of aluminum sulfate and a certain amount of sodium carbonate to the above-mentioned beneficiation wastewater, mix well, let stand for 20 minutes, and sample and analyze. The treatment results are shown in Table 1. When the amount of sodium carbonate in each liter of wastewater is 1250-1500 mg, the calcium, magnesium ions and heavy metal ions in the wastewater are all reduced, and the water quality is clearer.

Example Embodiment
[0024] Example 2:
[0025] Based on each liter of wastewater, add 1500mg of sodium carbonate to the above-mentioned beneficiation wastewater, mix and let stand for 20 minutes, then add a certain amount of aluminum sulfate and 10mg of anionic flocculant PAM, mix and let stand for 20 minutes After sampling and analysis, the processing results are shown in Table 2. It can be seen from Table 2 that aluminum sulfate has no effect on the removal of Ca ions and Mg ions in wastewater, but it can remove a large amount of heavy metal ions. The effect is best when the amount of aluminum sulfate per liter of wastewater is 30mg, and the effluent becomes clear. Transparent.

Example Embodiment
[0028] Example 3:
[0029] Based on each liter of wastewater, add 1500mg of sodium carbonate to the above-mentioned beneficiation wastewater, mix and let stand for 20 minutes, then add 30mg of aluminum sulfate and a certain amount of anionic flocculant PAM, mix and stand for 20 minutes Sampling and analysis, the processing results are shown in Table 3. It can be seen from Table 3: the effect of flocculant PAM on Ca in wastewater 2+ , Mg 2+ , Pb 2+ , Zn 2+ Both have a certain reduction effect, mainly to accelerate the precipitation of water-incompatible particles, and at the same time flocculate and precipitate heavy metal ions. The effect is best when the amount of PAM per liter of wastewater is 10 mg.
