转盘式过滤器由中心转鼓、转盘、反洗系统和配套控制电气系统等组成。转 盘固定在中心转鼓周围，并与中心转鼓具有连通孔。原水（污水）由中心转鼓的 一端开口流入转鼓内，并通过连通孔进入各转盘，转盘两侧装有过滤布，过滤布 为不锈钢丝或聚酯丝编织而成，过滤孔径最小可达 10μ m 。原水通过过滤布过滤 后，清水流出过滤布，从过滤水出口排出系统外。

The rotary filter is composed with rotary drum, rotary discs, backwash system and configured electrical control system. The rotary discs are fixed around the rotary drum with interlocking holes. The raw water (sewage) flows from the open end of rotary drum into the rotary drum and comes into each rotary disc via interlocking holes. The rotary disc can be equipped with filtration cloth on both sides that is weaved by metal wire or other organic materials with the diameter of filtration hole less than 10μ m. After the filtration of raw water by filtration cloth, the clean water flows out from the filtration cloth and then drains off the system through the exit of filtered water.

随着过滤的进行，过滤布内侧的截留杂质不断增加，过滤压差随之增加，透过滤布的水量减小。当杂质堆积到一定程度，中心转鼓液位达到设定值，需要进行反洗，将过滤布内侧堆积的杂质反洗出。

With ongoing filtration, the residual impurities inside filtration cloth will increase continuously, and the same is true for differential pressure of filtration. Meantime, the water flow is reduced through the filtration cloth. When the impurities are accumulated to a certain extent and the level of rotary drum reaches the preset value, it is necessary to conduct the backwash and get rid of the accumulated impurities inside filtration cloth.

反洗水泵抽取透过过滤布的清水，喷洒到过滤布外侧，将过滤布内侧的截留杂质冲洗下来，冲洗后污水掉落在接液盘内，然后排出装置外。

The backwash water pump draws out clean water through filtration cloth to sprinkle on the outside of filtration cloth until the residual impurities come off. After rinsing, the sewage drops into catchment tray and then drains off the device.

反洗时转盘旋转，反洗水喷洒不同角度的过滤布，直至转盘旋转一周，过滤布全部经过清洗，反洗停止，重新进入静止过滤过程，直至再次进行反洗。

The rotary discs take the spinning in the process of backwash. The backwash water sprinkles upon different places of filtration cloth until the rotary discs run one circle. After the thorough cleaning of filtration cloth, the backwash comes to the end and restores the static filtration process until the next backwash starts.

技术特点

(1) 滤布反洗系统更加先进

我公司在传统转盘过滤技术上进行改进，采用多喷头交错清洗方式，可在不增加反洗喷嘴水量和水压的情况下，扩大反洗面积并降低滤布疲劳损伤，提高了工作效率；并且还可根据反洗的需要，交替喷射反洗水工作，达到灵活调节和节水的效果。反洗过程中选用脉冲式冲洗方式，通过频繁冲击式反洗，更好的将滤渣从滤布上冲洗下去。

（2）采用德国原产滤布作为过滤介质，提高设备整体性能

滤布由特殊经纬线的不锈钢丝或聚酯丝编织而成，可供客户选择；

不锈钢滤布丝线采用316L 材质，精度更高，强度更高，透水率、开孔率
