Exploration of Phenol Sources in Wastewater Sludge of Personal Care Products Wastewater
Phenol is not added to the original and auxiliary materials of personal care products in an enterprise,and no phenol is produced in the production process.However,phenol is detected in the wastewater sludge.In order to explore the source of phenol in sludge,based on the exclusion of contaminated samples and detection errors,combined with the photocatalytic conditions,degradation mechanism and degradation intermediates of triclosan,it is concluded that the wastewater treatment process has photocatalytic degradation conditions,which may be the source of phenol in wastewater sludge.In addition,in order to avoid the omission of important detection indicators in hazardous waste identification with wrong conclusions,it is proposed to pay attention to pre-detection.
