【Abstract】 In this paper, the content of solid particles in the inflow and outflow water of the whirling sand-removing system of one sewage treatment factory has been measured together with the distribution of particle sizes as well as its specific gravity. In turn, the removing effect of this system has been evaluated. As a result, what caused the low removing rate and little amount of the removed sand in the actual running of this system has been found out.更多还原
