Abstract
The present invention discloses an advanced oxidation process of degrading nonsteroidal anti-inflammatory drugs in sewage by UV persulfate. The sewage flows to a secondary sedimentation tank by gravity, and sediments are precipitated and separated. NaSOsolution is added therein, and a UV lamp is opened. Effluent result is analyzed after photooxidation. The sewage is transferred into a contact disinfection pool to react with ClObefore discharging safely. The present invention uses a UV-based advanced oxidation process, which can effectively remove the nonsteroidal anti-inflammatory drugs in sewage, meets the requirements of sewage discharging, and decreases the environmental risk of nonsteroidal anti-inflammatory drugs. The method has some advantages such as simple equipments, easy operation, reasonable economy, as well as efficient treatment effect and high stability.
