Fenton method during processing, if pH control is bad, is easy to generate a large amount of hydroxide precipitating, and it is therein can
Soluble catalytic agent recycling is more difficult.Photo-Fenton method is higher to the removal efficiency of beta-lactam antibiotic, while TOC is gone
Except rate is also risen, and the enhancing of treated saprobia degradable ability, but the turbidity of sewage is required.It inhales
Attached method once substituted oxidizing process and was used, but was not used widely, for the equal energy of Adsorption efficiency of antibiotic
Reach 80% or more, but it the shortcomings that be that can generate new waste, and majority is carried out using active carbon in studying
Absorption, cost are very high.It is that removal antibiotic is most effective although technology combined techniques are not common methods in sewage treatment
Method, and handle after can reduce sewage toxicity.It is due to its process flow complexity, behaviour that this method, which is not used more widely,
Make at high cost, and cannot be used for continuous processing in most cases.
