Abstract:

The treatment methods of lead-bearing wastewater were reviewed, which were divided into chemical precipitation(hydroxide precipitation, sulfide precipitation, phosphate precipitation, ferrite precipitation and chelate precipitation), adsorption(active carbon adsorption, carbon nanotube adsorption and biomass adsorption), membrane separation(ultrafiltration and electrodialysis), ion exchange, bioremediation(phytoremediation and microbial remediation) and electrolysis. The concept, reaction conditions, removal efficiency, advantages and disadvantages were introduced respectively. Furthermore, the future development trend of lead-bearing wastewater treatment technology was prospected.

Key words: lead-bearing wastewater, precipitation, adsorption, membrane separation, bioremediation

摘要:

对当前含铅废水的处理技术进行综述,将其归纳为化学沉淀(氢氧化物、硫化物、磷酸盐、铁氧体和螯合沉淀)、吸附(活性炭、碳纳米管和生物质吸附)、膜分离(超滤和电渗析)、离子交换、生物修复(植物修复和微生物修复)和电解除铅,分别介绍了不同处理技术的概念、反应条件、去除效果、优缺点,并对含铅废水处理技术未来的发展趋势进行展望。
