According to the difficulty of wastewater treatment and the high pollution indicator of wastewater from gas production in remote gas blocks ,of western Sichuan ,a set of wastewater treatment equipment is developed .The device contains 11 units ,mainly using four kinds of ad-vanced technologies ,such as electro-coagulation air floatation technique ,inclined tube sedimenta-tion process ,sieve tray absorption-O3/H2 O2 complex oxidation process ,and filter-ozone compos-ite process .After field contrast test ,the optimum operating parameters of the device are deter-mined ,w hich the electrical air floatation current is about 3 500 A ,the processing flow is about 8 m3/h ,the pH value of effluent from the first order sedimentation tank is 13 or so ,the dosage of hydrogen peroxide is around 7 g/min , and the ozone dosage is about 96 g/min . T he field wastewater test result shows that the equipment has a good effect in removal of oil ,suspended solids and COD of wastewater in remote gas blocks of western Sichuan ,and the water quality reaches the primary level of the Integrated Wastewater Discharge Standard (GB 8978 -1996) , which provides a convenient and practical device for the field standard treatment with wastewater in the field .
