The invention relates to the technical field of wastewater treatment, in particular to a continuous membrane filtration type electroplating wastewater treatment method. The method comprises the following steps: a) feeding the electroplating wastewater into an oil separation tank for oil separation treatment, and feeding water separated from the oil separation tank into a reaction tank; b) removingoil and suspended matters in the water subjected to oil separation treatment in the reaction tank through a flocculating agent, ferrous sulfate and sodium hydroxide; c) feeding into a continuous membrane filtration system for filtration; d) feeding sludge discharged by the continuous membrane filtration system into a sludge concentration tank; e) feeding the sludge subjected to aeration treatmentinto a supercritical water oxidation system for treatment; and f) preparing the sludge treated by the supercritical water oxidation system into bricks. The treatment efficiency of the electroplatingwastewater is improved through the continuous membrane filtration system. Sludge is subjected to aeration treatment through a sludge concentration tank, organic matters are removed through the supercritical water oxidation system, and finally, the sludge is directly made into bricks. Therefore, the cost is saved, and the treatment efficiency is improved.
发明涉及废水处理技术领域，尤其是连续膜过滤式电镀废水处理方法。该方法的步骤为：a)电镀废水被送入隔油池内进行隔油处理，隔油池内分离出来的水送入反应池内；b)经过隔油处理后的水在反应池内，通过絮凝剂、硫酸亚铁、氢氧化钠来除去水中的油和悬浮物；c)送入连续膜过滤系统进行过滤；d)连续膜过滤系统排出的污泥则进入污泥浓缩池内；e)曝气处理后的污泥送入超临界水氧化系统内进行处理；f)将超临界水氧化系统处理后的泥制成转。本发明通过连续膜过滤系统来提高电镀废水的处理效率。通过污泥浓缩池对污泥进行曝气处理，再通过超临界水氧化系统清除有机物，最后将污泥直接制砖。从而节约了成本，提高了处理效率。
