Description

An integrated water intake and water purification device for surface water sources

technical field

The invention relates to a device for water intake and purification of water sources such as rivers, lakes, reservoirs, etc., and belongs to the technical field of river water intake purification treatment.

Background technique

As long as the water source of reservoirs in rivers and lakes is not polluted, it can be used for urban landscape, irrigation, greening, urban miscellaneous and process water, etc. However, due to various reasons, the water sources in rivers, lakes, and reservoirs are always polluted to a certain degree, and can only be used after purification. Usually, the water is taken out from the rivers, lakes and reservoirs and then transported to the purification treatment system over a long distance, which is time-consuming and laborious, with long and complex processes, high energy consumption, large floor space and high treatment costs. Water intake technology such as the disclosed "river water intake structure" of Chinese patent document CN203373703U.

Most of the water body purification documents of present various rivers, lakes and reservoirs are used for polluting water bodies, such as "a kind of water purification method for rivers and lakes and its special flow-making aeration equipment" disclosed by Chinese patent document CN 1300016C and disclosed by CN1163861A "Purification method and purification system for lakes and swamps". Due to the limitation of equipment and process, these technologies are limited to be used in sewage treatment plants, etc., and cannot be directly used in rivers and lakes.

CN102040317 A discloses a "A System and Method for Reusing Water from a River Channel Supplemented by Reclaimed Water", which adopts the method of combining a reoxygenated bank filter with a nanofiltration membrane to draw water from a river channel supplied by regenerated water, and after purification It is used for reuse of various types of non-direct drinking water. The system includes a reoxygenation type bank filter, a clear water tank, a flow control valve and a nanofiltration system. The reoxygenation type bank filter is set along the river. The sand layer is filled in the type bank filter, and non-woven fabrics are laid on the side of the bank filter close to the river; A baffle is laid on one side of the pool, and a fine mesh grid and a filter are arranged on the lower part of the baffle; the clean water pool is connected to the nanofiltration system through a pipeline and a flow control valve. This technology is also purified after taking water from the river, and cannot be directly used in rivers and lakes.

The water intake and purification integrated device of the present invention is realized by the following technical solutions:

The device includes a central cavity and a lateral flow inclined plate sedimentation tank. At least one lateral flow inclined plate sedimentation tank is arranged on the side of the central cavity, and the lateral flow inclined plate sedimentation tank is connected with the central cavity. The upper end of the inclined plate sedimentation tank is connected with a buoy, and the lower end is provided with a sludge vertical deflector. Fiber bundle filter material is wrapped on the outside, a floating rod is arranged on the upper end of the fiber bundle filter material, and an ultrafiltration membrane is installed inside the mesh bucket, and the ultrafiltration membrane is connected with a water delivery pipe, and the water delivery pipe is connected with a water pump.

The above device is placed in a river, lake or reservoir, and the water source enters from the lateral flow sloping plate sedimentation tank on both sides, and the mud and water are separated in the lateral flow sloping plate sedimentation tank, and the sediment enters the sludge vertical deflector and is discharged. The settled water enters the central cavity, and the floating rod makes the fiber bundle filter material tightly wrapped around the mesh barrel, and the water in the central cavity passes through the fiber bundle filter material, mesh barrel and ultrafiltration membrane in turn to obtain purified water , the effluent can meet the requirements of the three types of groundwater quality standards, and the purified water is pumped to the ground through the water pipe for reuse of various indirect drinking water, such as urban landscape, irrigation, greening, urban miscellaneous and process water, etc.

The invention integrates the water intake and water purification process into one, floats in the water body by itself, has a compact structure, is convenient to move, simple and convenient to operate and control, effectively removes pollutants in water, has good purification effect and high stability.

Detailed ways

As shown in Fig. 1, Fig. 2 and Fig. 3, the integrated water intake and purification device of the present invention mainly includes a central cavity 4 and a lateral flow inclined plate sedimentation tank 2, and a lateral flow tank 2 is respectively arranged on both sides of the central cavity 4. Inclined plate sedimentation tank 2 (more than two lateral flow inclined plate sedimentation tanks can also be arranged on the periphery of the central cavity 4), and the two lateral flow inclined plate sedimentation tanks 2 are connected to the central cavity 4. The upper end of each lateral flow inclined plate sedimentation tank 2 is connected with a buoy 1 , and the lower end is provided with a sludge vertical deflector 3 . The buoy 1 is used to improve the buoyancy of the whole device in water. The lateral flow inclined plate sedimentation tank 2 solves the problem of mud-water separation. As shown in FIG. 5 , the sludge vertical deflector 3 is composed of several vertical deflector pipes 13 . The bottom of the central cavity 4 is provided with a bracket 9, the mesh bucket 6 is connected to the bracket 9, and the bottom of the bracket 9 is provided with an aeration head 10. Figure 4 shows the structure of the mesh barrel 6. The outside of the mesh barrel 6 is wrapped with a fiber bundle filter material 5 , and a floating rod 8 is arranged on the top of the fiber bundle filter material 5 . The interior of the mesh bucket 6 is equipped with an ultrafiltration membrane 7 (see FIG. 3 ), the ultrafiltration membrane 7 is connected to a water delivery pipe 11 , and the water delivery pipe 11 is connected to a water pump 12 .

The operation process of the above-mentioned integrated water intake and purification device is as follows:

Place the above device in a river, lake or reservoir. Rivers, lakes, reservoirs and other water sources first enter from the lateral flow inclined plate sedimentation tank 2 on both sides, and the mud and water are separated in the lateral flow inclined plate sedimentation tank 2, and the sediment after sedimentation enters the sludge vertical deflector 3, It is discharged directly through the vertical guide pipe 13. The settled water enters the central cavity 4 along the horizontal direction, and the central cavity 4 can play the role of uniform water distribution. The floating rod 8 rises with the rise of the water level in the central cavity 4, and pulls up the fiber bundle filter material 5, so that the fiber bundle filter material 5 is tightly wrapped around the periphery of the mesh barrel 6, and under the action of hydraulic force, the fiber bundle filter material 5 Material 5 has larger gaps along the water flow direction and gradually becomes smaller, and the fiber density becomes larger, forming an ideal filtration layer and effectively improving the filtration effect. The water filtered out by the fiber bundle filter material 5 enters the barrel cavity through the mesh of the mesh barrel 6, and the mesh barrel 6 plays a role of supporting the skeleton. The water body in the central cavity 4 passes through the fiber bundle filter material 5, the mesh barrel 6 and the ultrafiltration membrane 7 in sequence to obtain purified water. The purified water is pumped to the ground by the water pump 12 through the water delivery pipe 11. When backwashing, there is no water in the central cavity 4, and the floating rod 8 falls to make the fiber bundle filter material 5 into a relaxed state, and the water enters the ultrafiltration membrane 7 from the water delivery pipe 11, and the ultrafiltration membrane 7 and the fiber bundle filter material 5 are reacted Aeration is carried out through the aeration head 10 to form air-water backwashing (air-water combined washing). During the process of bubble gathering and dispersing and hydraulic flushing, the fiber bundle filter material 5 is in a state of constant shaking, under the action of hydraulic force and rising air bubbles , get cleaned.
