The application provides a
wastewater treatment method and treatment equipment containing iron,
arsenic and
antimony, and relates to the field of
water pollution control and treatment. The
wastewater treatment method containing iron,
arsenic and
antimony comprises the following steps: S1, sequentially performing coarse
filtration and
ultrafiltration on the
wastewater containing iron,
arsenic and
antimony; S2, performing
reverse osmosis concentration treatment on the filtered wastewater again, and obtaining an enrichment liquid containing iron, arsenic and antimony; and S3, adding
pyrite into the obtained iron-arsenic-antimony enrichment liquid, stirring and heating to obtain a reduction solution. The wastewater treatment method containing iron, arsenic and antimony can repair water bodies polluted by iron, arsenic and antimony, simultaneously realize harmless treatment and
resource utilization of
solid waste (distiller's grains, electrolytic
manganese residue and the like), and achieve the purpose of treating
pollution with waste; the adsorbent of the application adopts a one-step
pyrolysis method, the process is simple, no chemical
reagent needs to be added, the adsorbent is
environmentally friendly, the adsorbent can be recycled, regenerated and reused, and the specific surface area and total pore volume of the adsorbent are large.
