Embodiment 1
[0104] Embodiment 1: Treatment of river raw water
[0105] Detect the river water, the raw water turbidity is less than 200NTU, input to such as figure 1 In the integrated water purification system and equipment shown, the sludge discharge valve 34 is opened to discharge sludge, the solenoid valves 31 and 22 are opened, and the main water pump 28, air compressor 33, and dosing pump 16 are opened at the same time, and the membrane module 37 passes through the main water supply system. The suction of the water pump 28 generates permeate water. Equipment into the water 7.5m 3 / h, concentrated water 1.5m 3 / h, the water output of the equipment is 6m 3 / h, backwash time 5min; water backwash flow 9m 3 / h, air flushing flow rate 13m 3 / h. Influent water quality: turbidity 34.5NTU, organic content 3.52mg / L, total coliform > 1600MPN / 100mL; effluent quality: turbidity 0.046NTU, total coliform not detected, organic content 2.25mg / L.
Embodiment 2
[0106] Embodiment 2: Treatment of reservoir raw water
[0107] Detect the reservoir water, the turbidity of the raw water is less than 8.0NTU, input to such as figure 1 In the integrated water purification system and equipment shown, the sludge discharge valve 34 is opened to discharge sludge, the solenoid valves 31 and 22 are opened, and the main water pump 28, air compressor 33, and dosing pump 16 are opened at the same time, and the membrane module 37 passes through the main water supply system. The suction of the water pump 28 generates permeate water. Equipment into the water 7.5m 3 / h, concentrated water 1.5m 3 / h, the water output of the equipment is 6m 3 / h, backwash time 5min; water backwash flow 9m 3 / h, air flushing flow rate 13m 3 / h. Influent water quality: turbidity 4.0NTU, organic matter content 2.50mg / L, algae 46 million / L; effluent water quality: turbidity 0.021NTU, algae not detected, organic matter content 1.6mg / L.
