Artificial ecologic floating island for brackish water purification

Abstract

The invention discloses an artificial ecologic floating island for brackish water purification. The artificial ecologic floating island comprises a floating island carrier. A plurality of planting pits for planting salt tolerance emergent aquatic plants are formed in the upper surface of the floating island carrier, a plurality of communicating holes are formed in the floating island carrier, theplanting pits are communicated with water needing water purification through the communicating holes, salt tolerance emergent aquatic plants are planted into the planting pits, the salt tolerance emergent aquatic plants are planted into the planting pits through silica sand, and roots penetrate through the communicating holes to make contact with the water needing water purification; the lower surface of the floating island carrier is provided with a plurality of anti-drifting devices in the length direction of the floating island carrier in parallel, and the anti-drifting devices are used forpreventing the floating island carrier from drifting in the region needing water purification. The artificial ecologic floating island is good in thermal insulation property, the survival rate of plants and microorganisms under the low-temperature condition is increased, and it can be ensured that plants and microorganisms can effectively purify the region needing water purification under the lowtemperature condition, the service life is long, and environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an artificial ecological floating island used for purifying saline water. Background technique [0002] In recent years, with the continuous development of industry, agriculture, and urbanization, the increase in salinity in freshwater waters is no longer just the effect of natural salinization such as seawater intrusion, rock weathering, and precipitation; Some domestic sewage, industrial wastewater such as printing and dyeing textile factories and steel factories are directly discharged into rivers, rivers, lakes and other natural waters without any treatment, resulting in more and more serious salinization in saline water. Due to the large amount of nutrient salts such as nitrogen and phosphorus in saline water, the diversity of the water ecosystem is single, the water body is very easy to become eutrophic, and causes water pollution, which seriously threatens the safe...

Problems solved by technology

For example: a new environment-friendly wet artificial floating island device, including a floating bed, a counterweight body and a connecting body, the floating bed and the counterweight body are connected through the connecting body, wherein: the floating bed is provided with a grid grille, and a hole net is provided at the bottom , and the floating bed is divided into a plurality of cultivation spaces, and the cultivation spaces are filled with substrates, the substrates are composed of 20% sepiolite, 15% chalk, 15% montmorillonite, 20% corncobs and 30% fine sand. % composition, the periphery of the floating bed is provided with anti-collision enclosures, and a layer of #TiO2 photocatalytic material is coated on the surface of the anti-collision enclosures; in the initial stage of floating island work, it can still achieve normal operation and meet the basic removal requirements, but under low temperature conditions , the survival rate of plants and microorganisms is low, so that the artificial ecological floating island cannot effectively treat the area that needs to be purified, which limits the overall operation and removal effect of the device. Therefore, the artificial ecological floating island in the prior art has been Unable to meet the needs of saline water purification
