A stepped composite ecological floating island for micro-polluted water treatment

Abstract

The invention provides a stepped composite ecological floating island for treating micro-polluted water bodies. The floating island is provided with a plurality of water purification pools distributed from bottom to top in a stepped shape. The solar stepped composite ecological floating island also includes: The water device includes a water suction pump and a water inlet pipe. The water inlet of the water inlet pipe is connected to the floating waters of the floating island, and the water outlet is located in the uppermost water purification pool; the drainage device is installed in the lowermost water purification pool. The drain is connected to the floating water area of ​​the floating island, which is used to automatically control the water level of the bottom clean water pool; the siphon is installed on each clean water pool above the bottom clean water pool, and when any clean water pool above the bottom clean water pool The water level in the water purification pool is higher than the preset water level, and the water in the water purification pool is diverted to the water purification pool below the water purification pool through a siphon; the plant planting pad is arranged at the bottom of each water purification pool and planted with purification plants. The device has simple structure and convenient application, and can be used for removing pollutants in polluted water bodies.

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.
