Multifunctional lake coastal ecological wetland system and operation method

Abstract

The invention discloses a multifunctional lake coastal ecological wetland system and an operation method. The multifunctional lake coastal ecological wetland system comprises an internal circulation system, a water distribution system, a wetland filter bed system, a water outlet system, a wetland plant system and an operation control system. The internal circulation system lifts and conveys lake water to the water distribution system at the front end of the wetland filter bed system, the water flows through the wetland filter bed system to be purified and lifted, and meanwhile, the water power of the lake water is improved. The operation control system is composed of a circulating water pump switch controller and a water distribution pipeline control valve, and is the key to play the functions of stable operation, overhaul and maintenance and non-point source pollution reduction in rainy seasons of the system. Through the construction of the multifunctional lake coastal ecological wetland system, the lake water body is circulated, purified and improved by utilizing the lake coastal space, and meanwhile, the lake coastal ecological landscape is enriched, so that the problems of single function and poor ecological landscape suitability of the traditional bypass purification measure are solved; and the adaptive capacity and the application range of the constructed wetland technology are further improved.

Description

technical field [0001] The invention discloses a multifunctional lake shore ecological wetland system and an operation method, belonging to the technical field of water body ecological purification. Background technique [0002] With the rapid development of society and the improvement of people's living standards, it is an inevitable trend to improve the living environment and pursue excellent quality of life. Urban lakes are often people's first choice for water leisure. However, due to the intervention and destruction of human activities, almost all urban lakes have reached the level of eutrophication or extreme eutrophication, and the limited environmental conditions cannot give full play to the value of ecosystem service functions of urban lakes. [0003] The eutrophication of urban lake water is serious, mainly due to the limited self-purification ability of the lake water, poor hydrodynamic force of the water body, and serious non-point source pollution in the rainy s...
