Floating island type constructed wetland treatment system based on lake center platform

Abstract

The invention discloses a floating island type constructed wetland treatment system based on a lake center platform, and relates to the fields of eutrophic water pollutant ecological interception, water quality improvement and decentralized sewage treatment. The system comprises a water purification lake center platform, a water inlet subsystem comprising a plurality of water inlet filler columns, a water drainage subsystem comprising one or more drainage filler columns, a water collection and distribution subsystem comprising a plurality of water collection tanks, and a platform wetland subsystem; the drainage filler columns are located in the center of the bottom of the water purification lake center platform, and the multiple water inlet filler columns are evenly distributed on the edge of the bottom of the water purification lake center platform with the drainage filler columns as the center; the platform wetland subsystem is located in the center area of the upper surface of the water purification lake center platform, and the multiple water collecting grooves are evenly distributed in the edge of the upper surface of the water purification lake center platform with the platform wetland subsystem as the center. The purpose of removing eutrophication of the water body is achieved in situ on the basis that the land beside the water area to be purified is not occupied.

Description

technical field [0001] The invention relates to the field of ecological interception of eutrophic water body pollutants, water quality improvement and distributed sewage treatment, in particular to a floating island type artificial wetland treatment system based on a lake center platform. Background technique [0002] In reality, it is necessary to carry out eutrophication control and lake ecological restoration for a large number of shallow lakes. Therefore, it is of great significance to carry out ecological restoration of shallow lakes and related governance of algae blooms, and the ecological service functions and regained service value are also more important. . [0003] At present, the technologies for ecological restoration of rivers and lakes mainly include submerged vegetation restoration, plant community mosaic, artificial wetland treatment, artificial floating island, sediment dredging, water bloom prevention and water purification, cyanobacteria collection and co...

Problems solved by technology

However, due to factors such as large water level fluctuations, environmental sensitivity, increasing water quality requirements, and surrounding land availability, river and lake systems have hindered the development of constructed wetland technology in river and lake governance.
