3. Deep water extraction: the deterioration of water quality generally starts from deep water, and the extraction of deep water to perform a certain degree of water treatment is a technology that can be selected for river sewage treatment.
4. Hydrodynamic cycling: circulation of the body of water may be achieved by means of pumps, jets or aeration, usually complete circulation, which may prevent stratification of the body of water or disrupt already formed stratification.
5. Aerating in deep water;
6. dredging bottom mud;
7. ecological control: the ecological control technology is to control the number of aquatic organisms within a certain range by utilizing the ecological relationship among the aquatic organisms.

The motor 37 is installed on the support rod 4, and the support rod 4 is of an automatic telescopic structure so that the stirring blades 38 are located at different water body depths. The solar energy conversion device further comprises a solar panel and a storage battery, wherein the solar panel converts solar energy into electric energy and stores the electric energy in the storage battery to be used by the motor 37.
The control principle of the stirring mechanism which is reset by the mutual matching of the two stirring mechanisms is as follows:
And 2, collecting the numerical value of the oxygen content monitoring sensor by the automatic control unit to display that the oxygen content of the position of the sewage treatment net 9 is too low to be beneficial to the growth of submerged plants and the treatment of sewage.
And 4, starting a motor 37 of another stirring mechanism, and repeating the action in the step 3 to push the expansion plate 32 which is started first to return to the original state from the maximum displacement state.
And 5, repeating the movement in the steps 3 and 4 to enable the expansion plate 32 to move back and forth, and enabling the stirring blades 38 to also move back and forth, wherein the stirring blades 38 continuously stir the river sewage to improve the oxygen content of the sewage.
And 6, when the oxygen content monitoring sensor detects that the oxygen contents of all parts in the river water body do not reach preset values, the motor 37 works all the time and enables the sewage treatment net 9 to move up and down and back in the river, and the sewage treatment net 9 and the stirring blades 38 move simultaneously to increase the oxygen contents of the water body.
Or, step 6, when the oxygen content monitoring sensor detects that the oxygen content of part of the water body in the river reaches a preset value, the motor drives the sewage treatment net 9 to move to the part, and the operation is stopped.
Or 6, when the oxygen content monitoring sensor detects that the oxygen contents of all parts in the river water body reach a preset value, the motor automatically stops working. The foregoing shows and describes the general principles, essential features, and advantages of the invention.
