The role of rotary lobe pump in the field of environmental protection

The rotor pump is a new type of sewage sludge conveying pump. In the sewage treatment plant, the screw pump is traditionally used to transport the sewage sludge. After the rotor pump entered China, it has almost replaced the screw pump in many occasions. Compared with the single screw pump, the rotary lobe pump has significant advantages such as small footprint, simple maintenance, low cost of spare parts, and low energy consumption. In addition, the rotor pump also has the characteristics of strong self-priming ability and forward and reverse reversible operation, and is used as a membrane suction pump in the membrane treatment process. Rotor pumps are widely used in the field of sewage, from primary sedimentation tank - aeration tank - secondary sedimentation tank - concentration tank - digestion tank to dehydrator feeding, and finally to the final dehydration of dry mud transportation, each process section can be Rotary pumps are used to transport sludge sewage.
