Description
Technical Field
The utility model relates to a water environment restoration technical field, especially a degree of depth adjustable aquatic plant growth platform.
Background
Water eutrophication is a phenomenon of water pollution caused by excessive content of plant nutrient substances such as nitrogen, phosphorus and the like, and internationally, the total phosphorus concentration (TP) in lake water is generally considered to be more than 0.02 mg/L, the total nitrogen concentration (TN) is more than 0.2 mg/L, and the total phosphorus concentration is considered to be the occurrence concentration of lake eutrophication.
Under natural conditions, with the continuous sedimentation and sedimentation of the river carrying impact substances and aquatic organism debris at the bottom of the lake, the lake is transited from poor nutrition to rich nutrition, and then is developed into marsh and land, which is a very slow process. However, due to the activities of human beings, after a large amount of industrial wastewater, domestic sewage and plant nutrients in the runoff of farmlands are discharged into the slow-flow water body such as lakes, reservoirs, estuaries, gulfs and the like, aquatic organisms, particularly algae, are propagated in large quantities, so that the variety and the number of the biological population are changed, and the ecological balance of the water body is damaged.
Investigation shows that 2 of class II water quality, 6 of class III water quality, 4 of class IV water quality, 5 of class V water quality and 11 of inferior class V water quality are satisfied in 28 national major lakes (reservoirs), main pollution indexes are total nitrogen and total phosphorus, and most of urban lakes in China are in eutrophication or super-eutrophication states.
