摘要:
针对矿区含铅废水处理效率低的问题，采用果壳生物炭协同氧化石墨烯强化超滤（SB-GO-UF）处理矿区含铅废水，考察了该工艺对COD、NH3-N、浊度和Pb2+的去除效果。结果表明，在水温为21.0~29.0 ℃、pH为5.0~5.2的条件下，组合工艺对COD、NH3-N、浊度和Pb2+的去除效果较好，平均去除率分别为91.2%、96.1%、97.6%和95.3%，其中对Pb2+的去除率比单独超滤工艺和传统工艺（曝气法）分别高15%~28%和18%~33%，出水COD平均浓度为17 mg/L、NH3-N基本在1.0 mg/L以下、浊度<1.0 NTU、Pb2+<0.40 mg/L，其水质优于《煤炭工业污染物排放标准》（GB 20426—2006）。采用清水、弱酸和弱碱进行反冲洗时，可使膜通量分别恢复至新膜通量的63%、88%、83%，综合考虑膜损伤，该体系采用弱碱进行反冲洗的效果较好。
Abstract:
In response to the low treatment efficiency of lead?containing wastewater in mining areas, a combined process using shell biochar combined with graphene oxide-enhanced ultrafiltration (SB-GO-UF) was employed to treat lead?containing wastewater from mining areas. The removal effects of this process on COD, NH3-N, turbidity and Pb2+ were investigated. The results showed that under the conditions of water temperature 21.0-29.0 ℃ and pH 5.0-5.2, the combined process achieved good removal efficiencies for COD, NH3-N, turbidity and Pb2+, with average removal rates of 91.2%, 96.1%, 97.6% and 95.3%, respectively. The removal rate of Pb2+ was 15%-28% higher than that of the standalone ultrafiltration process and 18%-33% higher than those of the conventional process (aeration method). The average effluent concentrations were 17 mg/L for COD, below 1.0 mg/L for NH3-N, less than 1.0 NTU for turbidity, and below 0.40 mg/L for Pb2+. The effluent quality met the standards of the Emission Standard for Pollutants from Coal Industry (GB 20426-2006). When backwashing with clean water, weak acid and weak alkali, the membrane flux could be restored to 63%, 88% and 83% of the new membrane flux. Considering membrane damage, weak alkali backwashing was more effective for this system.
