紫外消毒
紫外消毒利用UV-C光破坏病原体核酸使其失活,实现无化学药剂消毒,不产生消毒副产物,并对隐孢子虫等耐氯生物具有很强效果。
优势与注意事项
UV leaves no residual, so it is often combined with a small chlorine dose for distribution-system protection. Dose delivery depends on water UV transmittance, lamp aging and fouling, so validated reactors and monitoring are essential.
At higher doses, combined with hydrogen peroxide or chlorine, UV drives advanced oxidation for trace-organic destruction — the basis of the UV/AOP step in potable reuse.
