Problems solved by technology

When the system is backwashed, the air compressor is directly connected to the backwash air pipe, and the gas produced by the blower is unstable, resulting in unstable gas flow during backwashing, and it is easy for water to flow back into the air compressor, resulting in damage to the air compressor; The

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.

Abstract

The invention discloses an integrated water purification and supply method, which comprises the following processing steps of: (1) extracting raw water and injecting it into a membrane filtration device for treatment; (2) injecting the effluent water treated by the membrane filtration device into a water storage tank through a water pump; (3) adding a disinfectant into the water storage tank for disinfection treatment; and (4) outputting the disinfected water in the water storage tank directly for water supply. The invention also discloses a corresponding integrated water purification and supply system. The system of the invention maximumly optimizes the system configuration, and substantially saves the total investment and operating cost while ensuring the treatment effect, thus improving popularization and application in the water treatment industry. With two functions of water purification and water supply, the system provided in the invention is a feed water treatment systems and apparatus characterized by effluent water quality consistent with national standards, simple operation, convenient operation management, small floor space, low construction cost, and low running cost.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an integrated water purification method and system. Background technique [0002] The conventional treatment methods for water supply are mainly coagulation, sedimentation (clarification, air flotation), filtration and disinfection. However, the conventional water treatment method has the disadvantages of requiring more equipment, complex operation and management, large floor space, high investment and high operating costs. [0003] At present, most of the water plants or water supply stations built in remote areas are simple due to the constraints of conditions. The water supply treatment process adopted is simple, and some only set filtration and disinfection, and some only set disinfection, which cannot guarantee the safety of drinking water. In addition, the water supply plants or water supply stations in remote areas are small in scale and scattered in large number...
