纳米气泡水体透析技术/Nanobubble water dialysis technology

纳米气泡水体透析原理图/Principle diagram for nanobubble water dialysis

纳米气泡水体透析技术工作原理

       1、快速而持久的增加水体溶氧量，增加好氧生物活性；

       2、产生大量负氧离子，杀灭水体厌氧细菌及藻类；

       3、负电荷纳米气泡絮凝固体溶解物和化学物质上浮；

       4、负离子降解水体底泥，切断水体黑臭根源；

       5、形成生态链，完成水体自我修复。

The working principle of the nanobubble water dialysis technology

       1. increase the dissolved oxygen concentration and aerobic biological activity in a fast and persistent manner in order to improve activity of aerobic organism;

       2. produce large amount of negative oxygen ion, kill anaerobic bacteria and algae in water;

       3. nanobubble with negative charge will make solid solubility and chemical substances flocculate and go up;

       4. anion may degrade sediment in water body and cut off the black smelly water source;

       5. form eco-system and complete self-repairing of water body.

       纳米气泡自身的表面具有较强的张力，在水中不断收缩，后收缩到一定程度则消失溶解于水体中，这是它具有强大溶氧性的原因所在。而且在收缩的过程中，随着气泡的缩小，气泡内的气压呈反比例地迅速提高，让泡内气体处于超高压状态，这种超高压状态与超高温效应结合，是纳米气泡产生超声波性状的重要原因所在。因此能长时效进行氧化反应，并杀灭细菌。

       The surface of nanobubble has strong tension which may constantly shrink in the water to a certain degree and then disappear in the water body which is the reason of its strong oxygen dissolving ability. The bubble becomes smaller during shrinking process and the air pressure inside the bubble increases quickly in inverse proportion which make the gas inside the bubble under super-high pressure. This super high pressure together with super high temperature effect is the may reason for nanobubble to produce ultrasonic wave. Therefore long-time and effective oxidation reaction and bacteria killing is available.

       纳米气泡表面带有负电荷，所以气泡间难合为一体，在水体中能产生浓密而细腻的气泡，不会像常规气泡一样会融合增大而破裂。而且可以吸附水体中带正电的物质。利用表面电荷对水体微粒的吸附性，可以把水体中的有机悬浮物固定而分离，产生絮凝的效果，这特性是它得以在水处理中发挥出超常分离效应的关键所在。

       Negative charge exits on nanbubble surface, so it's difficult for two bubbles becoming one. Thick and fine bubbles will form in water which will not become one and break as normal bubbles. Instead, these thick and fine bubbles may absorb substances with positive charge in the water. By this absorption ability of surface charge on fine particles in water, the organic suspended substances in the water body will be fixed and separated which result in flocculation effect which is the key property for its super separation function in water treatment.
