Embodiment 1

[0035] Such as Figure 1~4 As shown, a river basin water ecological restoration system based on water conservancy deployment includes a sewage purification filter and a flood storage and drainage wetland. The sewage purification filter is set at the sewage outlet of the river to control the pollution caused by the upstream discharge of wastewater. The above-mentioned flood storage and irrigation wetlands are set 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 includes a first pool body 1 and a cover plate 2 closing the upper port of the first pool body 1 . The first partition 3 and the second partition 4 are sequentially arranged in the first pool body 1 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...

Embodiment 2

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

[0051] (1) Mix polytetrafluoroethylene powder and wollastonite powder evenly at a mass ratio of 9:1, extrude and granulate at 340°C to obtain base granules;

[0052] (2) Add polyvinyl alcohol into water, stir until dissolved, then add silicate powder to obtain a silicate dispersion; wherein, the addition of polyvinyl alcohol in water is 8g / L, and the addition of silicate is 42g / L;

[0053] (3) Mix the base particles described in step (1) with the silicate dispersion obtained in step (2) at a mass ratio of 3:45, stir for 20 minutes, ultrasonicate for 20 minutes, stir for another 3 hours, and extrude at 250°C for granulation. The particle size is 5-6 millimeters, that is to say.

Embodiment 3

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

[0056] (1) Mix polytetrafluoroethylene powder and wollastonite powder evenly at a mass ratio of 3:1, extrude and granulate at 320°C to obtain base granules;

[0057] (2) Add polyvinyl alcohol into water, stir until dissolved, then add silicate powder to obtain a silicate dispersion; wherein, the addition of polyvinyl alcohol in water is 15g / L, and the addition of silicate is 35g / L;

[0058] (3) Mix the base particles described in step (1) with the silicate dispersion obtained in step (2) at a mass ratio of 3:25, stir for 20 minutes, ultrasonicate for 20 minutes, stir for another 3 hours, and extrude and granulate at 250°C. The particle size is 5-6 millimeters, that is to say.

[0059] After testing, the performance of the microsphere fillers prepared in Exampl...

Abstract

The invention discloses a drainage basin water ecological restoration system based on water conservancy allocation. The drainage basin water ecological restoration system comprises a sewage purification filter pond and flood storage irrigation and drainage wetlands, the sewage purification filter pond is arranged at a sewage outlet of a river, an aerobic treatment chamber, an anoxic treatment chamber and a baffling anaerobic chamber are sequentially arranged in the sewage purification filter pond from left to right, and a baffling plate is arranged in the baffling anaerobic chamber; a water pump and an ejector are arranged, so that anoxic-anaerobic-aerobic continuous circulation is realized in a space sequence; the flood storage irrigation and drainage wetlands are arranged on the two sides of a river embankment, each flood storage irrigation and drainage wetland comprises a second pond body, a filter tank and a water collecting pond, a water distribution chamber, a surface flow wetland chamber, a subsurface flow wetland chamber and a water outlet chamber are arranged in each second pond body, and pollution factors in the water body are removed under the action of matrix filler and plants. Source control and sewage interception are achieved through the sewage purification filter tank, water conservancy allocation and ecological restoration are achieved through the flood storage irrigation and drainage wetlands, and development and allocation of water resources are promoted 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 river basin water ecological restoration system based on water conservancy deployment. Background technique [0002] Water is the source of life, the key to 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 for ensuring national water security. With the acceleration of industrialization and urbanization in our country, the level of development and utilization of water resources has gradually increased, and the demand for water resources has continued to increase. Due to the low utilization efficiency and serious waste of water resources, the contradiction between supply and demand has become increasingly prominent; at the same time, due to People don't pay enough attention to the development, ...
