Analysis of Commissioning Operation of Ⅴ-type Filter in Water Supply Treatment
The Ⅴ-type filter in a water plant uses homogeneous quartz sand as filter material,and achieves energy saving effect through the backwash form of gas-water backwashing + surface washing.The operation shows that the quartz sand is stable in filtering and backwashing,the backwashing effect is good,the pneumatic valve control is fast,the end suction pump is compact,the number of equipment is small,the daily maintenance is small,and the application is mature and reliable.From the design of the tank body to the construction,the whole process is strictly implemented in accordance with the relevant specifications and standards,especially in the high-load experimental debugging stage,with the addition of chemical dosing,coagulation and precipitation,the turbidity of the filtered effluent is stable within 0.5 NTU,and the discharge meets the requirements of the GB 5749-2006"Standard for drinking water quality".
