specific Embodiment approach 1

[0023] Specific Embodiment 1: In this embodiment, a gravity-driven drinking water purification device based on a near-zero operation and maintenance double-membrane method includes a three-phase flow high-speed sedimentation tank 1, a cleaning-free microfiltration membrane tank 2, and a gravity-driven ultrafiltration membrane tank 3 And high-efficiency mixed disinfection pool 4;

[0024] The water inlet pipe 11, the high-efficiency rapid sedimentation tank 1, the no-cleaning microfiltration membrane tank 2, the gravity-driven ultrafiltration membrane tank 3, the high-efficiency mixing disinfection tank 4 and the outlet pipe 30 are connected in sequence.

specific Embodiment approach 2

[0025] Specific embodiment two: the difference between this embodiment and specific embodiment one is: one end of the three-phase flow high-speed sedimentation tank 1 communicates with the raw water through the water inlet pipe 11, and the other end of the three-phase flow high-speed sedimentation tank 1 passes through The outlet pipe 12 is connected to one end of the no-cleaning microfiltration membrane pool 2, and the other end of the no-cleaning microfiltration membrane pool 2 is connected to one end of the gravity-driven ultrafiltration membrane pool 3 through the microfiltration water production pipe 17, and the gravity-driven ultrafiltration membrane The other end of the pool 3 communicates with one end of the high-efficiency mixing disinfection pool 4 through the ultrafiltration membrane water production pipe 20, and the other end of the high-efficiency mixing disinfection pool 4 communicates with the outlet pipe 30 through the sump 23 at the bottom. Other steps are the ...

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is: the three-phase flow high-efficiency rapid sedimentation tank 1 includes the sewage pipe 5 of the rapid sedimentation tank, the sewage valve 37, the water distribution wall 33, the gas release 6, three-phase flow rate immersed tube 7 and evenly distributed perforated water collection pipe 9; the water distribution wall 33 is arranged at the water inlet of the three-phase flow high-speed sinking tank 1, and multiple rows of small holes are arranged on the water distribution wall 33 to achieve uniform water distribution Function, the material of the three-phase flow rate immersed tube 7 can be steel pipe or plastic tube, the inner wall is rough, which is easy to attach biofilm, and the inside of the tube is a gas-liquid-solid three-phase mixed flow, and the water flow, gas and biofilm work together in the three-phase flow rate immersed tube 7 , simultaneously realize particulate matter, organic ...

Abstract

The invention discloses a gravity-driven drinking water purification device based on a near-zero operation and maintenance double-membrane method and a method for treating distributed source water by using the gravity-driven drinking water purification device. The invention relates to a drinking water purification device and a method for treating distributed source water by using the drinking water purification device. The invention aims to solve the multi-element pollution problems of turbidity, microorganisms, organic matters, NH3-N and the like in the existing device and method for purifying water source water. The gravity-driven drinking water purification device based on the near-zero operation and maintenance double-membrane method comprises a three-phase flow high-efficiency rapid sedimentation tank, a cleaning-free microfiltration membrane tank, a gravity-driven ultrafiltration membrane tank and a high-efficiency mixed disinfection tank, the water inlet pipe, the high-efficiency rapid sedimentation tank, the cleaning-free micro-filtration membrane tank, the gravity-driven ultra-filtration membrane tank, the high-efficiency mixed disinfection tank and the water outlet pipe are sequentially communicated with one another. When the gravity-driven drinking water purification device based on the near-zero operation and maintenance double-membrane method is used for treating distributed source water, the operation cost is almost zero. The gravity-driven drinking water purification device based on the near-zero operation and maintenance double-membrane method can be obtained.

Description

technical field [0001] The invention relates to a drinking water purification device and a method for treating distributed source water using the device. Background technique [0002] The water supply in my country's decentralized agglomeration areas has prominent problems such as difficulty in ensuring water quality safety, high energy consumption for long-distance water delivery, and difficulty in later operation and maintenance. Surface water is the main source of drinking water, mainly reservoir water, river water, and river water, as well as a small amount of mountain spring water, rainwater, and water from cellars. Moreover, surface water has common problems such as turbidity and the total number of bacteria exceeding the standard, and some of them also involve Organic matter and ammonia nitrogen pollution. In some areas, groundwater is still used as drinking water source, with slight turbidity and excessive microorganisms, and some areas are facing iron and manganese...
