Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] The three-dimensional floating bed-sinking bed combined river water purification device of the present invention includes an ecological floating bed system 11 and an ecological sinking bed system 12 .

[0047] Such as figure 1 , figure 2 As shown, the ecological floating bed system 11 is provided with a floating bed float 2, the specification of the floating bed float 2 is 33cm × 33cm × 6cm, and a planting hole is arranged in the floating bed float 2, and an emergent plant 1 is planted in the planting hole. The diameter of the hole is 17cm, and the planting density of emergent plants is 2-10 plants / m 2 The floating bed buoy block 2 is provided with an annular floating bed buoy 13 around it, and the floating bed buoy 13 is an annular hollow airtight structure with a diameter of 15cm, and the whole is rectangular. A floating bed inflation pipe 14 is arranged b...

Abstract

The invention discloses a three-dimensional floating bed and sinking bed combined type river water purifying device which comprises a reinforced ecological floating bed system and an ecological sinking bed system. The ecological floating bed system comprises emergent aquatic plants, filler and clams, wherein a biological film formed by a heterotrophic nitrification and aerobic denitrification bacterium hanging film is cultivated on the filler. The ecological sinking bed system comprises submerged plants, filler and ceramic particles, wherein a biological film formed by a humic acid reduction bacterium hanging film is arranged on the filler. The removal rate of COD in a water body can reach 60-80%, the nitrogen removal rate can reach 50-60%, the phosphorus removal rate can reach 20-30%, and the removal rate of humic acid and other large molecules difficult to degrade reaches 50-60%; by means of a float, the device can float up and sink down in water; due to the three-dimensional type structure and the adjustable structure, the water purification of a deep river bed is facilitated; in winter, ceramic particles can continuously have an adsorption effect so that water can be purified. A continuous effect is achieved for the water body of a river way, the ecological system of the river way is improved, and the self-purification capacity of the water body is restored.

Description

technical field [0001] The invention relates to the treatment of eutrophic water bodies such as river courses and lakes, and more specifically relates to a three-dimensional floating bed-sinking bed combined river water purification device and a treatment method thereof. Background technique [0002] In recent years, due to the rapid increase of population and the rapid development of industry, a large amount of nitrogen and phosphorus elements have been input into the water environment, resulting in eutrophication of water bodies and frequent outbreaks of red tide blooms. The ecological environment of the water body deteriorates, the sensory quality of the water body declines, and the massive reproduction of algae will consume a large amount of dissolved oxygen in the water, causing fish and other aquatic animals to face the threat of hypoxia death. The algae that proliferate in large numbers in the water will also emit a fishy smell. Some algae will secrete and release har...
