Embodiment 1

[0035] like Figures 1 to 4 As shown in the figure, a basin water ecological restoration system based on water conservancy deployment includes a sewage purification filter tank and a flood storage and irrigation wetland. The flood storage, drainage and irrigation wetlands are arranged on both sides of the river bank 51 to improve the self-purification capacity of the water body and facilitate further agricultural or municipal use.

[0036] The sewage purification filter tank includes a first tank body 1 and a cover plate 2 that closes the port on the first tank body 1 . The first tank body 1 is provided with a first partition 3 and a second partition 4 in turn from left to right, the front and rear ends of the first partition 3 and the front and rear ends of the second partition 4 They are respectively seamlessly connected with the inner walls of the front and rear sides of the first tank body 1 , and the bottom of the first partition plate 3 and the bottom of the second part...

Embodiment 2

[0050] A watershed water ecological restoration system based on water conservancy deployment is set according to the structure of Example 1, except that the microsphere filler is prepared by the following steps:

[0051] (1) Mix the polytetrafluoroethylene powder and wollastonite powder uniformly according to the mass ratio of 9:1, and extrude and granulate at 340°C to obtain base particles;

[0052] (2) adding polyvinyl alcohol to water, stirring to dissolve, then adding silicate powder to obtain silicate dispersion; wherein, the addition of polyvinyl alcohol in water is 8g / L, and the addition of silicate is 42g / L;

[0053] (3) mixing the base particles described in step (1) and the silicate dispersion liquid obtained in step (2) according to a mass ratio of 3:45, stirring for 20 minutes, ultrasonicating for 20 minutes, stirring for 3 hours, and extruding and granulating at 250°C, The particle size is 5-6 mm, that is, it is obtained.

Embodiment 3

[0055] A watershed water ecological restoration system based on water conservancy deployment is set according to the structure of Example 1, except that the microsphere filler is prepared by the following steps:

[0056] (1) Mix the polytetrafluoroethylene powder and wollastonite powder uniformly according to the mass ratio of 3:1, and extrude and granulate at 320°C to obtain base particles;

[0057] (2) adding polyvinyl alcohol to water, stirring to dissolve, then adding silicate powder to obtain silicate dispersion; wherein, the addition of polyvinyl alcohol in water is 15g / L, and the addition of silicate is 35g / L;

[0058] (3) mixing the base particles described in step (1) and the silicate dispersion obtained in step (2) according to a mass ratio of 3:25, stirring for 20 minutes, ultrasonicating for 20 minutes, stirring for another 3 hours, and extruding and granulating at 250°C, The particle size is 5-6 mm, that is, it is obtained.

[0059] After tests, the performance ...

Abstract

The invention discloses a river basin water ecological restoration system based on water conservancy allocation, including a sewage purification filter tank and a flood storage and irrigation wetland. There are an aerobic treatment room, anoxic treatment room, and a baffled anaerobic room. The baffled anaerobic room is equipped with a baffle plate. By setting a water pump and an ejector, the anoxic-anaerobic-aerobic continuous space sequence can be realized. Circulation; the flood storage, drainage and irrigation wetlands are arranged on both sides of the river embankment. The flood storage, drainage and irrigation wetlands include a second pool body, a filter tank and a water collection pool. Through the action of matrix fillers and plants, the pollution factors in the water body are removed. The invention realizes source control and sewage interception through the sewage purification filter, realizes water conservancy allocation and ecological restoration through flood storage, drainage and irrigation, and promotes the development and configuration of water resources through water quality purification and maintenance.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a watershed water ecological restoration system based on water conservancy allocation. Background technique [0002] Water is the source of life, the essential of production, and the foundation of ecology. Water conservancy is an important support for economic and social development, the core content of ecological civilization construction, and a strategic infrastructure to ensure national water security. With the acceleration of industrialization and urbanization in my country, the level of development and utilization of water resources has gradually improved, and the demand for water resources has continued to increase. Due to the low efficiency and serious waste of water resources, the contradiction between supply and demand has become increasingly prominent; at the same time, due to People do not pay enough attention to the development, utilization a...
