Study on CMC method of synergetic degradation in waste drilling fluid

This article proposes a degradation method of CMC in waste drilling fluid by microwave and coagulation synergetic degradation. This study investigated the influence of the coagulant dosage, pH value and reaction time and so on to the response. The result shows that the degradation effect is remarkable: the dosing quantity of ferric chloride coagulant is 80 mg/L, pH = 5, microwave reaction time is 6 min, the power is 700 W, in this situation CMC solution could be degraded completely, This degeneration efficiency of the method is high, the time is short, the expense is low and the experiment operation is easy and feasible.
