| الوصف: | To solve the problems of unstable chemical oxygen demand (COD), turbidity and suspended solid (SS) removal for the electrocatalytic process and unstable operation of the subsequent ultrafiltration membrane–reverse osmosis membrane in a centralised fracturing wastewater treatment plant in Inner Mongolia, the integrated dissolved ozone flotation (DOF) process was proposed to replace the original electrocatalytic process. Multiple processes, such as ozonation, flotation, coagulation and decolourisation, can be achieved in one integrated DOF reactor. The results showed that the removal efficiency of COD, colour, turbidity and SS in the DOF process could reach 25.4, 49.9, 95 and 96%, respectively. Meanwhile, the treatment cost was reduced by 47% (i.e., 1.77 RMB/m3 for the DOF process) compared with the electrocatalytic process. HIGHLIGHTS Multiple physio-chemical processes can be achieved in one integrated DOF reactor.; The DOF exhibited higher removal efficiency compared with the electrocatalytic process.; The DOF has stable removal efficiency during drastical influent quality variation.; The treatment cost was reduced by 47% compared with the electrocatalytic process.; |
