盘片式过滤器作为污水回用中超滤的预处理部分，其作用主要是进一步降低来水中的颗粒、悬浮物和胶体等，减轻超滤负荷，避免当石英砂反洗不及时或操作工人误操作时漏砂而导致超滤膜被损坏。如果其出现故障，势必影响超滤以及整个污水回用的正常的运行。%The disc type filter is the preprocessing part in the wastewater reuse, its main function is to further reduce the inflow of particles, suspended solids and colloids, to reduce ultrafiltration load, to avoid the ultrafiltration membrane to be damaged when the hourglass sand quartz sand backwash is not timely or operator mistakenly operates. If it fails, it will affect the normal operation of wastewater reuse.
