一、净水构筑物运行管理(一)沉淀池的运行管理要点1.及时掌握原水的水质和水量的变化情况,定时测定浊度、PH 值等,发现水质、水量变化,及时调整凝聚剂的用量或采取相应措施。2.注意观察絮凝效果和沉淀池内矾花的形状,遇到异常情况,应及时查出原因和采取措施。3.及时排泥。如沉淀池底积泥过多,将会缩小沉淀池过水断面,相应缩短沉淀时间,减少沉淀池容积;如排泥过于频繁又会增加耗水量。
I. Operation and management of water purification structures (1) Operation and management points of sedimentation tanks 1. Timely monitoring of changes in the quality and quantity of raw water, timing determination of turbidity, pH, etc., finding changes in water quality and water volume, and timely adjusting the amount of coagulant Or take appropriate measures. 2. Observe the effects of flocculation and the shape of the pods in the sedimentation tank. When an abnormal situation is encountered, the cause should be identified and measures must be taken. 3. Drain the mud in time. If too much sediment is deposited at the bottom of the sedimentation tank, the sedimentation section will be reduced to reduce the sedimentation time and reduce the sedimentation tank volume. If the sludge is discharged too frequently, it will increase the water consumption.
