%X The treatment of natural gas purification wastewater by microwave assisted processes was studied. The removals of the color, COD, suspended solids (SS), oil content, bacteria and the corrosion rate of the wastewater were investigated in the processes of flocculation and oxidation under microwave irradiation, and the comparable experiments at room temperature and without microwave irradiation were also conducted. Compared with normal flocculation (no microwave), the dosing amounts of PAC and PAM flocculants reduced 100 mg/L and 5 mg/L, respectively, sedimentation time was shortened to 1/4 of normal flocculation time, and COD removal efficiency increased 4.6% in the flocculation with microwave irradiation. The removal efficiency of oil content in the wastewater reached 94%, and sterilization efficiencies of sulfate reduction bacteria in two wastewaters were more than 97%, and the corrosion rate of the wastewater decreased to 1/7 of the original, and the biodegradation of the wastewater increased greatly after the treatment. It shows that microwave assisted processes have a significant effect on the treatment of natural gas purification wastewater.
