Key Points

The study aims to explore the degradation mechanisms of polyacrylamide using low-dosage Cu-MOF-74 and peroxymonosulfate (PMS).
Employed hydrothermal treatment techniques for viscosity reduction.
Analyzed the degradation of high-concentration polyacrylamide in produced water.
Assessed the efficiency of Cu-MOF-74 combined with PMS under optimal conditions.
Achieved significant viscosity reduction with the Cu-MOF-74/PMS treatment, with over 70% breakdown of PAM observed.
Identified key degradation products confirming the effectiveness of the mechanism.
Demonstrated rapid degradation rates under hydrothermal conditions enhancing treatment efficiency.

Implication

Investigates viscosity reduction of polyacrylamide in produced water, suggesting an effective treatment method.

Abstract

The high viscosity of oilfield produced water caused by high-concentration polyacrylamide (PAM) readily leads to quartz sand filter clogging, necessitating efficient viscosity reduction during the sedimentation stage.This study employed hydrothermally...
