Abstract

A new kind of complex coagulant SPAS has been prepared by using fly ash as primary row materials. Tests about its application to the tertiary oil-recovery wastewater in oilfield treatment have been made and the coagulation mechanism has been discussed. The experimental results show that SPAS has a good coagulation effect on the treatment of tertiary oil-recovery wastewater with wide range of pH. The coagulation effect of SPAS has a great advantage over PAC and PFS.
