| titleOfInvention | Efficient flocculent precipitate purification method for polymetallic ore benefication wastewater |
| abstract | The invention discloses an efficient flocculent precipitate purification method for polymetallic ore benefication wastewater. Specifically, the purification method comprises the steps of: neutralizing and regulating the pH value of benefication wastewater by adopting a little amount of alkaline materials; then sequentially feeding a proper amount of proper suitable flocculant for efficient flocculation and a little amount of efficient coagulant aids for fast precipitation; separating sludge from water through action of a partition wall, wherein the treated wastewater achieves primary standard of national Integrated wastewater discharge standard (GB8978-1996); through SV30 evaluation; settling for 5minutes to achieve 45-55mL of supernatant by volume; and settling for 15 minutes to achieve 70-80mL of supernatant by volume. The purification method can fully utilize the traditional benefication wastewater lime and sedimentation process, is simple in procedure, and can simultaneously remove suspended particulate matters, organic matters and heavy metal ions in wastewater, is high in flocculation efficiency and fast in sedimentation speed, and can better solve the purification problem of the low-concentration and high-tubidity polymetallic ore benefication wastewater of multiple heavy metals. |
