Experimental Study on Pressure Treatment of Algae-bearing Raw Water in Drinking Water Plant
The raw water of drinking water plants is mostly taken from lakes and reservoirs and other closed water systems.The high concentration of raw water containing algae affects the quality of water.The existing algae removal technology has poor treatment effect on raw water containing algae or causes secondary pollution by breaking algae cells and releasing intracellular substances.In this study,pressure treatment was used to eliminate the influence of algae on drinking water quality.The effects and parameters of pressure pretreatment were studied by small scale experiment.The results showed that pressure treatment had obvious removal effect on the typical microcystis aeruginosa,and the maximum removal effect could be achieved when the pressure increased to 0.7 MPa.The rupture of vesicles by pressure is an instantaneous and irreversible process.Pressure will not cause the rupture of algal cells,and their contents will not be released and pollute the water.
