【摘要】 以某黄金矿山井下废水为研究对象,进行了混凝、超声强化混凝处理和氧化处理试验研究,结果表明铁系混凝剂SF去除砷、锑效果最好,砷和锑去除率分别达99.81%和91.84%以上;超声强化混凝处理可有效提高锑除去效果;二氧化氯在低p H值条件下去除氰化物效果好,超声强化混凝和氧化可以作为该井下废水处理的主要工艺单元。更多还原

【Abstract】 Taking a gold mine wastewater as the research object,the results of the coagulation,ultrasonic strengthening coagulation treatment and oxidation treatment show that the iron series coagulant SF works best to remove arsenic and antimony,arsenic and antimony removal rate is above 99. 81% and 99. 81% respectively;Ultrasonic strengthening coagulation treatment can improve the effect of antimony removal effectively; The treatment effect of chlorine dioxide cyanide under the condition of the low p H is good,ultrasonic strengthening coagulation and oxidation can be used as the main unit of the mine wastewater treatment process.更多还原
