Iron electrode electric flocculation arsenic removal method for underground water containing sensitive coexisting substances
The invention discloses an iron electrode electric flocculation arsenic removal method for underground water containing sensitive coexisting substances, which comprises five links of underground water extraction and pretreatment, iron electrode electrolytic flocculation, standing sedimentation, drainage or recharge, and sludge discharge and treatment, and couples an underground water extraction technology and a sequencing batch iron electrode electric flocculation technology. By improving the utilization efficiency of limited iron ions, the adverse effect of sensitive coexisting substances on As removal in the flocculation process is avoided or reduced to the greatest extent, the arsenic removal efficiency is greatly improved, and meanwhile, the yield of arsenic-containing sludge and the subsequent treatment cost are reduced. The technical method disclosed by the invention is simple and practical, wide in raw material source, green in technological process, relatively low in operation cost and beneficial to large-scale popularization, and has remarkable economic, environmental and social effects, and construction operation has no too high requirements on equipment.
本发明公开了一种含敏感共存物的地下水的铁电极电絮凝除砷方法，包括：地下水抽提及前处理、铁电极电解絮凝、静置沉降、排水或回灌、排泥与处理处置五个环节，耦合了地下水抽提技术与序批式铁电极电絮凝技术，通过提升有限铁离子的利用效率，进而最大程度地避免或减小絮凝过程中敏感共存物质对As去除的不利影响，大幅提升除砷效率的同时减少了含砷污泥产量与后续处理费用。本发明技术方法简单实用，原材料来源广泛，工艺过程绿色，施工操作对设备没有过高的要求，运行成本相对低廉，利于规模化推广，具有显著的经济、环境与社会效应。
