STABILIZATION OF ACTIVE SLUDGE AFTER WASTEWATER TREATMENT CONTAMINATED BY P ETROLEUM PRODUCTS
Journal Title: Вісник Національного Авіаційного Університету - Year 2016, Vol 67, Issue 2
Abstract
Purpose: Biochemical purification of wastewater containing refined petroleum products takes place due to the oxidation of pollutants by active sludge organisms. As a result of this process the intense consumption of pollutants by active sludge and its growth occurs. Therefore, the possibility to use active sludge containing refined petroleum products after wastewater treatm ent requires its stabilization. Methods: In this work the oxidation by a 30% hydrogen peroxide solution was studied for its use as a stabilizer. Ch emical oxidizers, including hydrogen peroxide destroy organic polymers retaining free water thus promoting water rele ase from the structure of sludge particles. On the other hand remains of fine structur ed oxidized biopolymers can lead to filter clog ging, that is, reduce moisture exchange of sludge. Results: The experiment was carried out to find out the correlation between the doses of hydrogen peroxide and the resistivity value of sludge filtration. Discussion: Stabilized active sludge can be used as a fuel for boiler rooms, which in its turn will reduce natural gas consumption for the enterprise needs.
