所述阳极与阴极间的工作电压为2~8V，电流密度为10～250mA/cm2 ，阳极与阴极间的工作电压最好为3～5V，最佳电流密度为100～150mA/cm2 。
所述的混凝沉淀池中加入的絮凝剂为铝盐、铁盐、聚铝、聚铁中的一种或多种的组合，加入量为2～500g/m3；所述的助凝剂为聚丙烯酰胺，加入量为2～300g/m3 。
在对淡水、海水和苦咸水、废水、市政污水进行处理时，首先通过装置内的混凝沉淀池，在搅拌作用下加入适量的絮凝剂和助凝剂，加快水中固体颗粒物质（如化学沉淀物、混凝处理所形成的絮体和生物处理的污泥等）相互凝聚，形成粒径和质量较大的颗粒固体物，并快速沉淀下来而从水中去除，同时通过沉淀作用去除水中的砂粒；然后，进入一级气浮池，溶气释放器产生的微小气泡粘附水中大量的轻质悬浮物（如细小固体颗粒、油、苯等）上浮，达到固液分离或液液分离的效果，从而降低水中的COD、氨氮、色度、浊度等；一级气浮池的出水进入电解气浮池，电解产生的强氧化性物质杀灭水中的微生物、细菌、藻类和浮游生物，并氧化分解水中的有机物，使得水中的COD、色度、浊度、氨氮、臭味等污染指标大幅度降低；最后通过排渣池收集沉淀物和浮渣，使得水体获得净化。
所述的电解气浮池在对淡水进行消毒净化时，通过覆盖于阳极表层的纳米涂层的电催化作用，降低电解的过电位，从而使淡水在较低的电压条件下电解产生游离基，如初生态的氧、初生态的氯、羟基和氢，并发生以下四个作用：
1、电解产生的游离基如初生态的氧、初生态的氯、羟基等强氧化物质可以杀灭水中的微生物、细菌、藻类和浮游生物，产生的尸体可以与阴极产生的大量微小气泡结合上浮去除，消除微生物、藻类和浮游生物的污染并降低浊度；
2、电解产生的强氧化物质可以氧化分解水中的有机物，降低水中的COD、色度、臭味等污染指标；
3、在电场作用下，一方面使得水中的悬浮物、胶体、带电微粒等物质脱稳，另一方面水中的阳离子、阴离子分别向阴极和阳极移动，在阴极和阳极发生双电层作用和多电层作用，形成沉淀诱发絮凝作用，促使细小的悬浮物、胶体、带电微粒等物质形成粗大的絮凝体，加速杂质沉降，有效降低SS、浊度等污染指标；
4、电解时阴极产生的大量初生态的氢可形成氢气小气泡，具有气浮效果，随着气泡的上浮，会粘附大量的轻质悬浮物，达到固液分离或液液分离的效果，从而进一步降低水中的COD、色度、浊度等。
所述的电解气浮池在对海水和苦咸水净化消毒时，是通过覆盖于阳极表层的涂层的电催化作用，降低电解的过电位，从而使一级气浮后的海水、苦咸水在较低的电压条件下电解，产生初生态的氯[Cl]和初生态的氢[H]，并发生以下四个作用：
1、电解产生的初生态的氯[Cl]具有强氧化性，可以杀灭水中的微生物、藻类和浮游生物，产生的尸体可以与阴极产生的大量微小气泡结合上浮去除，彻底消除微生物、藻类和浮游生物的污染并降低浊度；
2、电解产生的初生态的氯[Cl]能氧化分解水中的有机物，降低水中的COD、色度、臭味等污染指标；
3、在电场作用下，一方面使得水中的悬浮物、胶体、带电微粒等物质脱稳，另一方面水中的阳离子、阴离子分别向阴极和阳极移动，在阴极和阳极发生双电层作用和多电层作用，形成沉淀诱发絮凝作用，促使细小的悬浮物、胶体、带电微粒等物质形成粗大的絮凝体，加速杂质沉降，有效降低SS、浊度等污染指标；
4、电解时阴极产生的大量初生态的氢可形成氢气小气泡，具有气浮效果，随着气泡的上浮，会粘附大量的轻质悬浮物，达到固液分离或液液分离的效果，从而进一步降低水中的COD、色度、浊度等。
所述的电解气浮池在对废水、市政污水进行处理时，是通过覆盖于阳极表层的涂层的电催化作用，降低电解的过电位，从而使一级气浮后废水、市政污水在较低的电压条件下电解，产生初生态的强氧化性物质，在有大量氯离子存在时，产生的是初生态的氯[Cl]和初生态的氢[H]；在没有氯离子存在时，产生的是初生态的氧[O]、羟基[OH]和初生态的氢[H]，并发生以下七个作用：
1、电解产生的初生态的强氧化性物质杀灭水中的微生物、细菌、藻类和浮游生物并与阴极产生的大量微小气泡结合上浮去除，消除微生物、细菌、藻类、浮游生物的污染并降低浊度；
2、电解产生的初生态的强氧化性物质快速氧化分解废水中的有机物，使得大分子物质分解为小分子物质，降低废水中的COD，同时提高B/C值，改善可生化性，为后续处理创造更好的生化条件；
