چکیده
In this work, the degradation performance of Fe2+/PAA/H2O2 on three typical pollutants (reactive black 5, ANL, and PVA) in textile wastewater was investigated comparison with Fe2+/H2O2. Therein, had a high removal RB5 (99%) mainly owing to contribution peroxyl radicals and/or Fe(IV). Fe2+/H2O2 showed relatively PVA (28%) resulting from ·OH. comparative removals ANL. Additionally, more sensitive pH than The coexisting anions (20–2000 mg/L) inhibition their followed an order HCO3− > SO42− Cl−. Humic acid (5 10 mg C/L) posed notable following reactive 5 (RB5) ANL PVA. practical effluent, dramatically inhibited by 88%. Bioluminescent bacteria test results suggested that toxicity treated systems lower possible pathways proposed mechanisms hydroxylation, dehydrogenation, demethylation. may favor evaluation advanced treatment wastewater.

Background and Objective: In this research, the performance of coagulation and flocculation process for the removal of pollutants from raw wastewater as well as anaerobic unit effluent of biological treatment of textile dyeing factory wastewater treatment plant was investigated. Methods: For this purpose, the Jar test unit as a batch reactor, FeCl3, PAC, and Alum as coagulants, and two polyelec...
متن کاملPerformance of electrical stimulated anaerobic baffled reactor for removal of typical pollutants from low-strength municipal wastewater at low temperatures
Background: Although anaerobic system has been successfully used for treating the strong industrial wastewater, its efficiency for low-strength wastewater as municipal wastewater is not satisfying. This study aimed to enhance the capability of an anaerobic baffled reactor (ABR) for treating municipal wastewater. Methods: A 7-L ABR with 5 compartments was operated for a 287-day period fed with ...
