本发明属于一种用聚焦激光产生的等离子体,通过消毒和/或降低化学耗氧量的方法,对被污染的液体进行净化的工艺过程。通过用某种由聚焦激光产生的等离子体的气体与被微生物污染的水溶液相接触的办法来进行溶液消毒。同样,含有有机物的废水可以通过使它同某种含氧的气体接触的办法来进行净化,在这种气体中,由聚焦激光产生的等离子体促进有机物氧化而变成无害的产物。
The present invention pertains to a process for purifying contaminated liquids by means of a focused laser generated plasma by a method of disinfecting and / or reducing the chemical oxygen demand. Solution sterilization is performed by contacting the gas with a plasma generated by the focused laser with an aqueous solution contaminated with microorganisms. Similarly, wastewater containing organic matter can be purified by contacting it with some oxygen-containing gas, where the plasma generated by the focused laser promotes the oxidation of the organics into a harmless product.
