The effect of products of adhesive wastewater oxidation with Fentons reagent on biological treatment in SBR

The advanced oxidation process with Fenton’s reagent can be used in industrial wastewater treatment, especially for the degradation of not easily biodegradable contaminations. Chemical oxidation of industrial wastewater or other substances as a pre-treatment before biological purification is the most effective method of wastewater treatment. However the Fenton process requires low pH of wastewater and final neutralization with a big amount of iron-containing precipitate. Thes paper presents laboratory experiments dealing with the treatment of adhesive wastewater in an sequencing batch reactor following the Fenton process without final neutralization.
