Water eutrophication control system and control method based on remote control

Abstract

The invention discloses a water eutrophication control system and method based on remote control. The control system comprises a remote control center, a nutrition detection unit for detecting parameters of a water body of the constructed wetland, an image acquisition unit for acquiring image data of a water body collection area on a water inlet side of the constructed wetland and a water body ecological landscape area on a water outlet side of the constructed wetland, a water body treatment area arranged between one side of an outlet of the water body collection area and one side of an inlet of the water body ecological landscape area, and a nutrition control unit used for controlling the water body collection area, the water body treatment area and the water body ecological landscape area to operate, wherein the water body collection area is communicated with the water body ecological landscape area through the water body treatment area. By monitoring the quality condition of the water body in real time and accurately eliminating the eutrophication problem of the water body, residual nitrogen, phosphorus and organic pollutants in the water body can be rapidly purified and discharged into rivers and lakes, the labor cost and the economic cost are greatly reduced, and large-scale application and popularization are facilitated.

Description

technical field [0001] The invention belongs to the technical field of eutrophic water body treatment, and in particular relates to a water eutrophication control system and control method based on remote control. Background technique [0002] Eutrophication of water body refers to the phenomenon of water quality pollution caused by excessive content of nutrients such as nitrogen and phosphorus in the water body. Generally, the water body with total phosphorus reaching 0.02 mg / L and inorganic nitrogen reaching 0.3 mg / L is already in a state of eutrophication. Nutritization and eutrophication of water body are one of the important signs of extreme deterioration of water quality. When eutrophication of water bodies is caused by human activities and industrial and agricultural production, a large amount of nutrients such as nitrogen and phosphorus required by organisms enter slow-flowing water bodies such as lakes, rivers, and bays, causing algae and other plankton to multiply ...

AI Technical Summary

Problems solved by technology

The complexity of pollution sources, nitrogen and phosphorus nutrients that lead to eutrophication of water quality, both natural sources and man-made sources; both exogenous and endogenous, which brings difficulties to control pollution sources

At present, the control methods of water body eutrophication mainly include chemical, biological and physical methods. Using chemical methods to put chemicals or reagents in lakes will inevitably bring different degrees of harm to water quality; Putting in a large number of algae-eating animals may have a certain impact on the lake's biological population structure and biodiversity; microorganisms, etc. are affected by the environmental conditions of the water body and cannot achieve ideal results. Physical methods include mechanical removal, direct filtration and Methods such as precipitation algae or plankton removal can directly remove algae or plankton in the water body without obvious negative effects

No matter what method is used to effectively control the eutrophication of the water body, it is difficult to monitor the quality of the water body in real time and accurately remove the eutrophication problem of the water body, and it will also generate a lot of extra human and economic costs, which is not conducive to Large-scale application and promotion
