Shandong Mingquan New Material Science and Technology Co.,Ltd.methanol plant has a set of sewage treatment,the process is"pre-treatment+biological treatment",the main treatment process adopts"A/O+SBR(with filler)"process.Treatment scale is 260 m3/h,the treated water meets the discharge standards,the original design of aeration is jet aeration(jet pump+aeration fan,operation by increasing dissolved oxygen in water through jet aerators),the aeration method exists in the aeration head is easy to block,uneven distribution of dissolved oxygen,jet pump scouring cavitation serious,high power consumption and other operational difficulties,so the aeration method has been technologically modified to a lifting air cyclone aerator method.to solve the above problems,while saving electricity,to maximize the benefits of enterprises.
