【摘要】：采用"電絮凝-流態(tài)化微電解耦合法"技術(shù)處理鉛鋅冶煉廢水,主要考察了pH、水力停留時(shí)間、鐵炭投加量、電壓、鐵炭粒度等反應(yīng)條件對廢水中鉛、氟離子去除率的影響,并對比了不同電極材料、不同電極數(shù)量和極板間距下的處理效果。研究結(jié)果表明,鋁電極對鉛鋅冶煉廢水具有更好的處理效果;在最佳工藝條件(考慮能耗成本),即采用四塊鋁電極、pH 4.0、水力停留時(shí)間30 min、鐵炭投加量45 g、電壓5 V、鐵炭粒度20~27目時(shí),電絮凝-流態(tài)化微電解耦合法對廢水中各離子的去除效果最佳;處理實(shí)際鉛鋅冶煉廢水時(shí),鉛去除率達(dá)到了99.9%,氟去除率達(dá)到了82.7%,各種離子殘留濃度均低于污水綜合排放標(biāo)準(zhǔn)(GB 8978-1996)一級(jí)標(biāo)準(zhǔn)值。
[Abstract]:The electroflocculation-fluidized micro-electrolysis method was used to treat lead-zinc smelting wastewater. The effects of pH, hydraulic retention time, iron and carbon dosage, voltage, iron and carbon particle size on the removal rate of lead and fluorine ions in the wastewater were investigated.The effects of different electrode materials, different electrode number and plate spacing were compared.The results show that aluminum electrode has better treatment effect on lead-zinc smelting wastewater.Under the optimum technological conditions (considering the cost of energy consumption, such as pH 4.0, HRT 30 min, iron and carbon dosage 45 g, voltage 5 V, iron and carbon particle size 20 ~ 27 mesh), four aluminum electrodes are used.The electroflocculation-fluidized micro-electrolysis coupling method has the best effect on the removal of the ions in the wastewater, and in the treatment of the actual lead-zinc smelting wastewater,The removal rate of lead and fluorine reached 99.9 and 82.7 respectively. The residual concentrations of various ions were lower than the first grade standard of wastewater discharge standard GB8978-1996.
