摘要
采用不同吸附剂、氧化剂和曝气方法对浮选废水进行色度去除试验研究,确定先加Ca(ClO)2,再加活性炭(40～80目)的方法联合处理浮选废水色度.结果表明:在 200 mL原水中,活性炭的最优用量为1g,降低Ca(ClO)2 的使用量为 1g时,对浮选废水进行色度处理,能较好地去除浮选废水色度,且处理后的溶液pH值符合排放标准.
Abstract
Different adsorbents,oxidants,and aeration methods were used to study the chromaticity removal of flotation wastewater.The method of first adding Ca(ClO)2 and then adding activated carbon(40～80 mesh)was determined to jointly treat the chromaticity of flotation wastewater.The results showed that in 200 mL of raw water,the optimal dosage of activated carbon was 1 g,and when the usage of Ca(ClO)2 was reduced to 1 g,the chromaticity treatment of flotation wastewater could effectively remove the chromaticity,and the pH value of the treated solution met the discharge standards.
