机械过滤器，主要作用是去除水中的悬浮物质、固体颗粒。悬浮固体是水中不溶解的非胶态的固体物质，它们在条件适宜时可以沉淀。用过滤器截留悬浮固

体，以过滤介质截留悬浮固体前后的重量差作为衡量过滤器发挥作用的依据。过滤介质一般使用D=0.5-1.0mm的滤料介质.根据水中的杂质成份可以采用单层过

滤、双层过滤和多层过滤。

The main function of mechanical filter is to remove suspended matter and solid particles from water. Suspended solids are non-colloidal solids that are insoluble in water and can be precipitated under suitable conditions. The filter is used to intercept the suspended solids, and the weight difference before and after the interception of the filter media is used as the basis to measure the function of the filter. The filter media generally use the filter media of Dust 0.5-1.0mm. According to the impurities in the water, single-layer filtration, double-layer filtration and multi-layer filtration can be used.
