Problems solved by technology

[0008] Aiming at the problem of low reoxygenation efficiency in the existing water body aeration and reoxygenation technology, the present invention provides an in-situ aeration device and method for bottom mud in a wind-solar hybrid system, which can simultaneously aerate the bottom mud and the overlying water body. Oxygen disturbs the sediment to increase the content of active sludge, and inhibits the release of N, P nutrients and various pollutants in the sediment. At the same time, the device system can adjust the migration, has a certain flexibility, and can fundamentally solve the problem of water pollution. Anoxic problems with sediment

Embodiment 1

[0052] combine Figure 1-3 , an in-situ aeration device for sediment in a wind-solar hybrid system, comprising a wind-solar hybrid power supply system and a microporous aeration system, wherein the wind-solar hybrid power supply system includes an inverter 4, and the microporous aeration system includes a blower 5 and a microporous aeration system Gas plate 8, the output of inverter 4 is connected with air blower 5, and air blower 5 is connected with microporous aeration plate 8. The structure principle of the present invention is simple, the manufacturing cost is low, and it is easy to realize.

[0053] The reoxygenation efficiency in the existing water body aeration and reoxygenation technology is generally 20-35%. Aiming at the problems that the reoxygenation efficiency of the existing aeration technology is not high, the anaerobic environment of the bottom mud cannot be changed and the bottom mud continues to release nutrients, the present invention The oxygen efficiency ...

Embodiment 2

[0055] Similar to Example 1, the length of the air hose 7 connecting the blower 5 and the microporous aeration plate 8 is adjustable, so that the aeration device can aerate river and lake sediments at different water depths. The air hose 7 is made up of several sections of 0.5m short pipes connected. When the microporous aeration plate 8 is not completely flattened in the bottom mud, the floating plate 6 is pulled by the gravity of the microporous aeration plate 8. It will be in a tilted state. At this time, increase the number of short pipes at the air outlet of the blower 5, so that the hoses are in a slack state, and the floating plate 6 restores balance, thereby realizing that the length of the air hose 7 can be adjusted to be suitable for different water depths. river course.

Embodiment 3

[0057] Similar to Embodiment 1, wherein, the upper part of the balance fixing device 9 is a balance bar, and the lower part is an anchor;

[0058] The balance fixing device 9 is shaped like a ship's anchor, and its material is stainless steel. It mainly consists of an upper balance bar and a lower anchor. It can balance and fix the floating plate 6 just below the floating plate 6. Iron chain adjusting device 10 is positioned at the center of floating plate 6, and connects balance fixing device 9 by iron chain, and iron chain is wound on the cylinder of iron chain adjusting device 10, retracts and controls the length of iron chain, so balance fixing device 9 is not affected by The limitation of water depth is suitable for rivers and lakes with different water depths.

Abstract

The invention discloses a wind-solar complementary system bottom mud in-situ aeration device and method and belongs to the field of water bottom material treatment. The device comprises a wind-solar complementary power supply system and a microporous aeration system. The wind-solar complementary power supply system comprises an inverter. The microporous aeration system comprises an air blower and a microporous aeration plate. The output of the inverter is connected with the air blower, and the air blower is connected with the microporous aeration plate. The wind-solar complementary system bottom mud in-situ aeration device and method aim to overcome the defects that existing aeration is mainly applied to riverway or lake water, the capacity of oxygen to permeate bottom mud is limited, and the black and odorous bottom mud anaerobic environment cannot be directly and effectively improved. Aeration is directly conducted through bottom mud; oxygen is directly permeated into the bottom mud without causing intensive disturbance of the bottom mud; the bottom mud anaerobic environment is effectively improved; aeration is driven through the natural energy wind-solar complementary system; the problem that in the wild, it is inconvenient to supply electric power is solved; energy consumption is saved. The wind-solar complementary system bottom mud in-situ aeration device is simple in structural principle, low in production cost and easy to implement and has high environmental benefits and economic benefits.

Description

technical field [0001] The invention relates to the field of bottom treatment of water bodies, and more specifically relates to an in-situ aeration device and method for bottom mud of a wind-solar hybrid system. Background technique [0002] The wind and solar hybrid power generation system is a device that combines wind energy and solar energy to realize simultaneous wind and solar power generation and complementary power generation. It uses the complementarity of wind energy and solar energy to make up for the defects of wind power and photovoltaic independent systems, and can obtain relatively stable output power. Realize power supply continuity, stability and reliability. [0003] The phenomenon of black and odorous rivers is common in our country, and it is a major chronic disease in the field of water pollution control. One of the important causes is the oxygen consumption of the sediment. Sediment, as an important part of the water environment, is one of the main des...
