Multifunctional lake coastal ecological wetland system and operation method

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 wat
