Composite ecological floating island device for purifying polluted water

Abstract

The invention discloses a composite ecological floating island device for purifying polluted water. The device comprises a shell. The device is characterized in that a culture substrate is arranged onthe substrate; the culture substrate is divided into two parts, the upper half part of the culture substrate is an artificial soil layer, and the lower half part of the culture substrate is an original soil layer; the lower end of the original soil layer is located in the shell; a low-temperature protection device is arranged above the culture substrate; the low-temperature protection device protects an ecological floating island by sensing rising and falling of the air temperature; a water diversion mechanism and a drainage mechanism are correspondingly arranged at the two ends of the interior of the shell; the water diversion mechanism and the drainage mechanism each comprise a lower protective shell fixed in the shell; a driving motor is arranged on one side of each lower protective shell; and a first driving shaft is installed on one side of each driving motor in a sleeving mode. The device is simple in structure and can rapidly and continuously purify a water source and perform heat preservation for the floating island in cold winter.

Description

technical field [0001] The invention relates to the technical field of composite ecological floating islands, in particular to a composite ecological floating island device for purifying polluted water. Background technique [0002] The ecological floating island is an artificial floating island that aims at eutrophic water quality and uses the principle of ecological engineering to degrade the content of COD, nitrogen and phosphorus in the water. It can greatly improve the transparency of the water body, and at the same time, the water quality index has also been effectively improved, especially for the inhibition of algae. The main effect of ecological floating islands on water purification is to use the roots of plants to absorb eutrophication substances in the water, such as total phosphorus, ammonia nitrogen, organic matter, etc., so that the nutrients in the water body can be transferred, and the water body can be reduced due to closed or insufficient self-circulation....

AI Technical Summary

Problems solved by technology

[0003] In the past, traditional ecological floating islands mostly used PVC pipes, stainless steel pipes, wood, moso bamboo, special expanded polystyrene and other materials for the frame, while ceramsite, vermiculite, expanded perlite, porous ceramics, pumice, etc. were used as carriers Or matrix, with different types of combinations, but limited to simple loose combinations, poor system stability, focusing on the use of water space, but not much construction of underwater systems, resulting in insufficient use of underwater space and weak water purification capabilities

Part of the composite ecological floating island technology only equips traditional ecological floating islands with solar panels, nutrient substrates, circulation systems, etc., the system is unstable, the construction method is relatively complicated, or the production cost is high, the purification efficiency is low, and the existing The floating island device is difficult to survive the winter, and the green plants on the floating island device need to be replanted in the second spring
