一种以外电场强化微电解技术处理含重金属废水的方法

Method for treating heavy-metal-containing wastewater by external electric field reinforced micro-electrolysis technology

Abstract

The invention discloses a method for treating heavy-metal-containing wastewater by an external electric field reinforced micro-electrolysis technology, and belongs to the fields of water treatment technologies and recycling. In the method, the heavy-metal-containing wastewater is pretreated or not pretreated and then introduced into an external electric field reinforced micro-electrolysis reactor to be treated, a micro-electrolysis filler is filled in the reactor and is put in an external electric field with certain intensity, and micro-electrolysis reaction is promoted and reinforced through the reinforcing effect of the external electric field, so that metal ions in the wastewater are reduced into metal simple substances on the surface of the filler, and effluent can meet the requirement of the wastewater emission standard or can be directly recycled in the production process. The method has the advantages of high reaction speed, removal rate, recycling efficiency and environment compatibility and the like.
本发明公开了一种以外电场强化微电解技术处理含重金属废水的方法,属于水处理技术及资源化领域;本方法是将含重金属废水经过或不经过预处理后引入外电场强化微电解反应器进行处理,反应器内填充有微电解填料并将其置于一定强度的外电场中,通过外电场的强化作用,促进和强化微电解反应的进行,使得废水中金属离子在填料表面还原成金属单质,最终出水能达到废水排放标准要求或可直接回用于生产过程;本方法具有反应速度快、去除率高、资源化效率高、环境兼容性好等优点。
