Treatment Technology For Oilfield Wastewater Which

Treatment Technology For Oilfield Wastewater Which Containing Polymers By combining the electro-catalytic cracking technology and SSF wastewater purification technology, this technique first catalytically pyrolyzes the polyacrylamide in wastewater which contains polymers,and then purifies the water through SSF. The Mechanisms for this technology: mainly using the free radicals produced from electrolytic reaction of electrode, the electro-catalytic cracking device decomposes organics in wastewater and reduces its chroma..When electrolyzing, anode and cathode, under the voltage applied, form the electric field effects in wastewater, which dramatically improves the activity of water molecules. In particular, -OH is produced, which can oxidate many organic compounds. Technical Indexes High removal rate of SS, remaining at higher than 90%; Power consumption: 0.5 3 KW•h/m3; Electro-catalytic materials: composite catalytic materials such as composite metallic oxide; Utility range of Ph: 5.0 10.0; Retention time: 20 40min; Outlet water index (oil≤5mg/L, SS≤10mg/L and median particle diameter≤2μm). A short, simple and reliable process which demands small space; Small dosage and low overall operational cost; Effective purification after treatment ; Simple operation,safe,practical,and easy to manage.
