Description
Technical Field

Background
The water pollution is increasingly serious, if the wastewater treatment station is adopted to treat the polluted water, the cost is high, and if the wetland is adopted to purify, the occupied area is large. The in-situ microorganism treatment technology improves the sediment while improving the water quality, is beneficial to the recovery of the biological diversity of the water body, and improves the self-cleaning capacity of the water body to a certain extent [1]. Therefore, the purification of the water body can be realized by improving in-situ microorganisms in the water body, and the pollution of the water body purified by adopting exogenous microorganisms is avoided.
The in-situ microorganism number can be increased by putting in-situ microorganisms in a water body, or putting an accelerant into the water body, so as to promote the proliferation of the in-situ microorganisms, or inhibit the activity of exogenous microorganisms, so that the competitiveness of the in-situ microorganisms is improved. The complex enzyme biological promoter has an activating effect on microorganisms, so that the accumulated oxygen consumption of the microorganisms is obviously increased, and the self-cleaning capacity of the water body is effectively improved [2].
If the accelerating substance is directly put into the water body, the concentration of the put accelerating substance is diluted along with the flushing of the water flow, and the effect of the accelerating substance cannot be effectively exerted. The substances can be mixed into the river bed of the water body, namely the bottom mud of the water body, so that the loss of running water scouring is reduced. The existing underwater diving device is square and regular, the water flow resistance is high in the advancing process, and the underwater operation efficiency is low. Or the existing underwater vehicle adopts propeller power to excite the bottom mud, so that the underwater operation environment is poor.
