The invention relates to a method for treating smelting waste water, in particular to a micro-electrolysis method for lead and zinc smelting waste water, which belongs to the technical field of environment protection. The method comprises the following steps of: pretreating lead and zinc smelting acid waste water and feeding the pretreated waste water into an iron carbon bed for reacting, wherein the mass ratio of scrap iron to active carbon is 0.5-3:1; recycling most of heavy metal pollutants by performing a micro-electrolysis reaction, wherein a pH value is increased; adjusting the pH to be between 7.5 and 9.5 and generating a flocculating constituent from Fe<2+> and Fe<3+> generated in a previous reaction; precipitating and removing remaining heavy metal ions together with arsenic and fluorine pollutants by adsorption, flocculation and co-precipitation; and recycling supernatant serving as industrial water. The method has the advantages of good treatment effect on the lead and zinc smelting ...

The invention relates to a method for recovering copper in copper-containing acid waste water of a mine. The method is characterized by an iron-carbon microelectrolysis method and comprises the following steps of: importing waste water into an iron carbon microelectrolysis pond of an iron carbon bed and staying for 0.5-5 hours, wherein the waste water addition takes the standard that added waste water covers the iron carbon of the iron carbon bed and does not overflow out of the iron carbon bed as a reference so as to ensure that the waste water has microelectrolysis and replacement reactions, deposited copper is reduced on a cathode carbon surface so as to achieve the purpose of recovering metal copper, and the mass loading ratio of iron to carbon in the iron carbon bed is 1:5. The method has the advantages of simplicity, good treatment effect, low expense, easy operation, and the like and can be used for recovering copper in the copper-containing acid waste water of a mine.

The invention discloses a micro-electrolysis flocculation method for treating acid waste water containing heavy metals in mine. The treatment step is as follows: waste water pretreatment, iron-carbon micro-electrolysis and flocculation and precipitation, wherein the waste water is pretreated and then fed into an iron-carbon bed reactor with an iron-carbon mass filling ratio of 1-5 for reacting and staying for 5 mintues-6 hours, and most of heavy metal pollutants in the waste water are removed and recycled through micro-electrolysis reaction; the pH value is regulated to be 6.5-10 by effluent so as to carry out the flocculation and precipitation for further removing impurity ions, and the purification effect of the waste water can be enhanced by adding a new flocculant according to the water quality conditions; and after solid-liquid separation, the effluent of the waste water can be reused due to reaching the standard or discharged. The invention has the advantages of low treatment cost ...
