Energy-saving baffle type denitrification floating island

Abstract

The invention discloses an energy-saving bending-flow type denitrification floating island. The energy-saving bending-flow type denitrification floating island comprises a suspension system, a stabilizing system and a microorganism denitrification system, wherein the suspension system comprises PVC (polyvinyl chloride) pipes (5) and PVC pipes (6), the diameter of each PVC pipe (5) is 300 mm, and the diameter of each PVC pipe (6) is 200 mm; the stabilizing system is located in the position 1,000 mm below the suspension system, is a square internally-hollow stainless steel frame (2) and is connected with PVC floating balls (1) and solar cell panels (3), and the outer side length of the stainless steel frame (2) is 6,000 mm, and the inner side length of the stainless steel frame (2) is 3,000 mm; the microorganism denitrification system comprises an outer PVC box (4), soft filler (10), an inner PVC box (12), a filler fixing net (11), a middle PVC box (13) and a flow guide baffle (14), the inclination angle of the flow guide baffle (14) is 30 degrees, and water flow sequentially flows through the inner PVC box (12), the middle PVC box (13) and the outer PVC box (4). The energy-saving bending-flow type denitrification floating island has the advantages as follows: the structure is compact, and the denitrification efficiency is high; according to the microorganism denitrification system, the water flow flows through the soft filler (10) in a bending manner under the action of water gravity, and the labor is saved; the energy-saving bending-flow type denitrification floating island is high in stability and cannot overturn.

Description

technical field [0001] The patent of the invention belongs to the technical field of ecological restoration of water bodies, and specifically relates to an energy-saving baffle type denitrification floating island, which is especially suitable for ecological restoration of nitrogen pollution in lakes and reservoirs. Background technique [0002] With the further improvement of the degree of domestic industrialization, the further expansion of the scale of urbanization, and the application of a large amount of chemical fertilizers, a large amount of nitrogen-containing substances are directly discharged into the receiving water body or flow into the receiving water body with rainfall runoff, which greatly increases the outbreak probability of eutrophication in the water body and eruption intensity, especially in lakes and reservoirs with poor water mobility. According to the survey, nearly 30% of lakes and reservoirs in my country are in a state of eutrophication, and the sco...
