From each town in the County Street, all 印染废水水量大,色度深,碱性强,水质变化大,难降解有机污染物含量高。目前,印染废水普遍采用生化法,混凝沉淀法,混凝气浮法和活性炭吸附法进行处理。这些方法投资费用高,管理难度大,脱色效果和去除率都不理想。近几年来报道了许多用电化学法处理印染废水的研究成果和技术专利,并应用于各种规模的印染企业的废水治理工程,收到了良好的效果。利用微电解法处理染料废水,CODcr去除率达67%左右,脱色率几近100,。结果表明酸性废水有利于去除CODcr,和脱色,选择pH值为4的酸性废水为宜;延长微电解反应时间有利于提高处理效果,但会增加投资和运行费用,反应时间控制在5O min为宜;石灰乳的用量过多或过少均会影响CODcr的去除,调pH值为9时较合适;微电解反应器选择铁屑与焦炭的质量比为1:1效果最佳。 铁炭微电解法处理实际生产染料废水,实验结果表明,微电解法对染料废水有明显的去除效果,进水pH为l左右,接触时间为0.5h时,COD的去除率在60,左右,色度去除率大于94,;微电解法主要通过氧化还原作用和铁的絮凝作用去除COD和色度。 【【【【微电解填料【用户体验】开始啦～提供免费的“微电解填料样品”进行实验;开通了“微电解填料咨询热线”;同时提供全面详细的微电解填料资料等等。】】】】 3.2 含砷废水的处理 随着冶金和化工等行业发展以及贫矿的开发,砷伴随主要元素被开发出来,进入废水中的砷数量相当大。据1995年中国环境状况公报报道,95年砷排放量达到1084吨,比94年增长4.4%,1996年中国环境状况公报报道,96年砷排放量达到1132吨,比95年增长4.2%。含砷废水有酸性和碱性,当中一般也含有其它重金属离子。砷与铅等共同作用会使废水的毒性更大,国内外都曾发现废水中砷的中毒事件。 含砷废水中砷的存在形态受pH的影响很大,在中性条件下,可溶砷的数量达到最大,随着pH的升高或降低其溶解的数量都将降低。pH为5.0时,溶液中砷主要以无机砷的形态存在,当pH为6.5时,有机砷为其主要存在形态。但由于含砷废水的来源并不单一,其成分也是复杂多变的。 含砷废水的处理在六十年代就已得到世人的关注。如能回收利用则不仅可解决了砷对环境的污染问题,而且经济效益显著,节约资源。目前,比较系统的处理方法有化学沉淀法,物理法以及新兴的,最具发展前途的—新型铁碳微电解技术。 砷化物是一种高毒性物质,对环境污染严重。含砷废水目前常采用离子交换法,沉淀法和浮选法治理。陆萸英等对含砷废水处理进行了系统的概述。在上述方法中,沉淀法加入沉淀剂的量较难控制,过少除不尽砷,过多会造成二次污染。浮选法则因泥渣中含水量大,也易造成二次污染。Nazarora G N等报道了消耗Fe电极的电凝结方法处理含砷废水,但此法耗电量很大。彭根槐等人对铁屑微电池反应处理含砷废水进行了研究,结果表明通过腐蚀电池电极反应产forming the Government, enterprises and the public forces and actively participate in, sharing a strong atmosphere.
