The Application of Screw Pump in Sewage Treatment
With the rapid development of modern industry and technology, sewage pollution has become a serious problem. In order to effectively control the pollution of sewage and protect the environment, the treatment of sewage has become an important issue in the current social public welfare. Therefore, the use of screw pumps in sewage treatment has become the focus of attention in all aspects.
Screw pumps, also known as screw centrifuges, have the advantages of being able to transport liquids with suspended solids and corrosive substances. Firstly, the screw pump is composed of an impeller, a stator, and a drive motor, etc, using the conveying principle of pressure and suction to transport liquids. Secondly, the screw pump works by relying on the rotation of the screw blades to form a vacuum suction, so that the liquid can be continuously sucked in, not only the suction is large, but also the suction power is stable. Therefore, this kind of screw pump has strong adaptability and can transport gases, liquids, and suspensions. Moreover, compared with other pumps, its structure is more simple, its operation and maintenance is convenient, and its running noise is also very low.
Therefore, the screw pump is now widely used in the treatment of sewage and other occasions. In the sewage treatment, a certain amount of chemical agents and treated water are added to the sewage, and then a certain amount of bacteria are added to speed up the treatment process. After the screw pump is used to stir the sewage, the macromolecular organic matters in the sewage are rapidly hydrolyzed and oxidized, and then it will be separated and precipitated in the sedimentation process. Then through the filtration of the filter material, the fine suspended solids can be removed from the sewage, thus achieving the purpose of effectively purifying the sewage.
In addition, screw pumps are also used to treat sludge. Generally, after being treated by the screw pump, the sewage sludge can be effectively condensed and separated, and then the scum generated by the separation process is sent to the wastewater treatment station for further treatment, so as to achieve the purpose of reducing the volume of the sludge and improving the water quality.
In conclusion, the screw pump is an important equipment in the industry and it has many advantages. In particular, its use in the treatment of sewage and sludge is very effective. Therefore, it is necessary to increase the use of screw pumps in sewage treatment and make them play an important role in the ecological environment protection.
