Water purification device system: consists of coagulation tank, sedimentation tank, filtration tank, water quality stabilization dosing device, backwashing device, water pump and electrical control cabinet.
1, coagulation tank: the use of WTH pipeline static mixer, through the hydraulic automatic mixing coagulant. The raw water with coagulant is fed into the coagulation tank from the water inlet pipe, and mixed with the special eddy current reaction and coagulant, so that the suspended matter in the water and coagulant can fully contact and react to form alumina. General water purification device is to use eddy current reaction to make water and coagulant mixing, but the effect by the change of water volume and not stable. Can also be used in special mixer stirring, so that the suspended solids in the water and coagulant full contact reaction to form alum flowers, not subject to changes in the amount of water and affect the effect.
2, sedimentation tank: the water is coagulated with coagulant to form alum, flow to the equipment of the sedimentation tank for sedimentation, sedimentation tank using inclined tube sedimentation method, the surface load of 7-8m?/m2.h. After trapezoidal inclined plate sedimentation chamber sedimentation to complete the separation of solid-liquid precipitation, precipitation of sludge is discharged into the mud hopper.
3, filtration tank: the water after precipitation flows to the filtration tank filtration, filtration tank structure at the bottom of the cloth water pipe, the middle of the quartz sand, the upper part of the white coal. The filtration speed is 7~10m/h, the flushing strength is 14~16L/m2.s, and the last clear water flows into the clean water pool for disinfection and drinking. The backwash cycle of the filtration pool is about 12 hours, and the backwash time is 5-10 minutes. The filtration part is filtered by polystyrene bead ball.
