摘要
以造粒还原铁粉为吸附剂,采用吸附剂法处理印染废水中的锑。通过连续通水试验考察了p H值和温度对锑吸附的影响。结果表明,用造粒还原铁粉吸附工艺对含锑质量浓度0.8 mg/L的实际生产废水进行处理,处理后出水的锑浓度可降至0.1 mg/L以下,完全符合GB 4287—2012的排放标准。
The sorbent method ed reduced iron powder as an s applied to treatment of wastewater conta ning antimony with granulat- adsorbent. The influence of pH value and temperature on the adsorption of antimony is investigated by continuous water experiments. The results show that treatment of the ac- tual production wastewater containing antimony of 0.8 mg/L cerium with the granulated reduced iron powder adsorption process, the antimony content of outlet can be reduced to less than 0.! mg/L, which can fully meet the requirements of the emission standards of GB 4287-2012.
