The above process ensures the full exchange of oxygen, carbon dioxide and nutrients, while removing waste and impurities.

[0003] Whether it is an artificial lake, an eco-tank or other water circulation system, when the water lacks fluidity, the dissolved oxygen content in the water decreases, organic matter accumulates, and provides conditions for the overgrowth of algae and bacteria, resulting in less sunlight penetrating the water, weakened photosynthesis of aquatic plants, a sharp drop in the dissolved oxygen content of the water, and the death and decay of aquatic plants. The dead water phenomenon destroys the ornamental value of the ecological landscape, causes the death of aquatic organisms due to lack of oxygen, produces harmful substances, pollutes the water, destroys the ecological balance, and even accelerates the deterioration of water quality.

[0021] 5. The angle of the solar panels of the device can be adjusted according to the actual situation of use. This function is simple, practical and easy to use;

[0022] 6. If the oxygen content of the water needs to be increased, a suitable spray device can be installed at the outlet of the solenoid valve.

4. A method for water circulation using the device according to claims 1-3, characterized in that: The specific steps of the method are: Step 1, preparation: according to the actual lighting conditions, the solar panel (5) is installed at an angle with the best total amount of lighting, the bag (15) is filled with fillers I (30), fillers II (34), and fillers III (35), the bag (15) is placed in the water filtration pipe (14), the water pump power line (33) of the water pump (13) is connected to the battery (6), and the water pump (13) is placed in the water body to be cleaned; Step 2, water filtering: the sewage valve (12) is closed, and the water pump (13) is operated to pump water. The water is transported to the sewage pipe (11) through the water delivery pipe (16). The water flows along the sewage pipe (11) into the connection pipe (10) and the water filter pipe (14). The annular boss (27) blocks the water from continuing to flow upward. The water flows through the filter water hole (28) into the water filter pipe (14). Large suspended dirt is blocked outside the water filter pipe (14) and deposited in the sewage pipe (11). The water flows into the bag (15) and is filtered by the filler I (30), filler II (34), and filler III (35) in turn, and impurities are further removed. The impurity-free water flows into the solenoid valve (7) through the connecting pipe II (32). The outlet of the solenoid valve (7) is the treated discharge area. Step 3, flushing the sewage pipe: when there is a lot of dirt in the sewage pipe 11 that needs to be removed, close the solenoid valve (7), open the sewage valve (12), and the water pump (13) works normally to pump water, and the dirt in the sewage pipe (11) is flushed and discharged by water flow; Step 4, water filter pipe maintenance: after the drain valve (12) is flushed, if there are still suspended particles in the water discharged from the outlet solenoid valve (7), disconnect the water pump (13), open the drain valve (12), drain the water in the drain pipe (11), unscrew the connecting cylinder (9), remove the water filter pipe (14) from the outlet pipe (8) and the connecting pipe (10), remove the cloth bag (15) from the water filter pipe (14), and clean or replace the cloth bag (15) and the filler I (30), filler II (34), and filler III (35).
