Laddered combined ecological floating island used for micro-polluted water disposal

Abstract

The invention provides a laddered combined ecological floating island used for micro-polluted water disposal. The solar laddered combined ecological floating island is provided with multiple ladderedwater purification ponds which are distributed from bottom to top and also includes a water feeding device, a drainage device, siphons and plant cultivation pads. The feeding device consists of a water pump and a water feeding pipe, a water inlet of the water feeding pipe is connected with a floating water area of a floating island body, and a water outlet is positioned in the water purification pond at the top; the drainage device is installed in the water purification pond at the lowest position, and a drainage port of the drainage device is connected with the floating water area of the floating island body and used for automatically controlling the water level of the water purification pond at the lowest position; the siphons are installed in each water purification pond above the waterpurification pond at the lowest position; when the water level of an arbitrary water pond above the water purification pond at the lowest position is higher than preset water level, water in the water purification pond is drained into the corresponding water purification pond below the water purification pond through the corresponding siphon; the plant cultivation pads are arranged at the bottomsof all the water purification ponds and used for cultivating and purifying plants. The laddered combined ecological floating island is simple in structure, convenient to apply and capable of being used for removing pollutants in polluted water.

Description

technical field [0001] The invention relates to the field of ecological restoration of water areas, in particular to a stepped composite ecological floating island used for the treatment of slightly polluted water bodies. Background technique [0002] Slightly polluted water generally refers to surface water affected by carbon, nitrogen, phosphorus and other pollution but with relatively low concentration. Most of the pollutants in this type of water have a concentration of no more than 10mg / L, and the sewage treatment process needs to be specially designed. The tail water discharged after the project treatment reaches the standard, the low-pollution domestic sewage, and the ponds, ditches, residential area wading landscapes and other water bodies that have been polluted by the sewage are all slightly polluted water bodies. composition. The densely populated, economically developed, and numerous cities in the middle and lower reaches of the Yangtze River are plagued by wate...

Problems solved by technology

However, the traditional aeration process often consumes a large amount of electric energy. At the same time, thermal power is mostly used for municipal power generation in my country, which produces a large amount of carbon dioxide, sulfur dioxide and other pollutants every year, which brings a series of environmental problems.
