征求意见稿尤其明确了“容易发生严重水污染问题而需要采取特别保护措施的地区”和“容易发生严重大气环境污染问题的地区”的锡、锑、汞及其化合物在污水和废气中的排放限值。这些排放值标准在一定程度上填补了现有标准的空白,如《污水综合排放标准》(gb 8978-1996)仅规定了污水中总汞的排放标准,并未涉及锡、锑的排放含量。

(1)fe2 与fe3 的循环还原氧化作用

电解过程中,铁阳极氧化电解,使得fe被氧化为fe3 。从铁的电极电位可以知道,在金属活动顺序表中排在铁后面的金属有可能被铁置换出来而沉积在铁的表面上。



由于fe3 极易水解生成氢氧化铁胶体沉淀,在弱酸性溶液中,氢氧化铁胶体丰富的比表面积显出较高的表面活性,能吸附多种金属离子及有机分子,能促进金属和有机分子的去除。在酸性条件下,fe2 与fe3 是很好的絮凝剂,把溶液ph调至碱性会形成fe(oh)2和fe(oh)3絮凝沉淀。由于电解过程有电荷配合作用,使得生成的fe(oh)3胶体絮凝剂的吸附能力高于一般药剂水解得到的fe(oh)3吸附能力。这样,废水中原有的悬浮物,通过电解反应产生的不溶物以及有机物降解大分子均可被其吸附凝聚。
