The main function of sewage lift pump is to pump sewage from one pool to another, or from one sewage treatment link to another, so as to realize sewage transportation, and it is widely used in sewage treatment.
The sewage lift pump is placed at the water inlet of the sewage treatment plant, and the sewage level transported by the sewage pipe network is low, so it is necessary to use the sewage lift pump to pump the sewage with low water level to the subsequent treatment process equipment. Many sewage treatment facilities are set according to the elevation. Through the water level difference, sewage can automatically flow to the subsequent facilities, reducing energy consumption. Another function is to pump the sewage treated in the last pond to the next pond for the next different sewage treatment process.
2. dosing pump
In dosing pump, sewage treatment chemicals are mainly added to sewage tanks, so that the sewage treatment chemicals react with some pollutants in sewage, remove pollutants and purify water quality. Sewage treatment chemicals are prepared in the dosing box, stirred evenly with a stirrer, and put into the solution box. Dosing pump inhales the liquid medicine from the solution tank, then mixes it with the water in the working medium and transports it to the polluted water, so as to achieve the purpose of dosing. The physical and chemical properties of sewage treatment chemicals contacted by dosing pump are different. When selecting the corresponding dosing pump according to the characteristics of the chemicals, the stability and accuracy of the dosing process should also be considered.
3. Sludge pump
The main function of the sludge pump is to pump the sludge produced after sewage treatment from the bottom of the pool for sludge treatment. Sludge pumps are mainly used in ponds that produce sludge, such as sedimentation tanks, sludge tanks, biochemical tanks and filtration tanks. The sludge pump pumps the generated sludge into the filter press, and the filter press removes water from the sludge to realize sludge treatment. The pressure of the sludge pump determines the water content of the sludge pumped by the sludge pump, which has a direct impact on the sludge treatment of the filter press.
