Automatic water level adjustment system and method for artificial wetland

Abstract

The invention relates to an automatic water level adjustment system and method for an artificial wetland. The automatic water level adjustment system comprises a wetland water inlet pipe, an adjustingtank, an adjusting tank water inlet pipe, a water distribution pipe, a water collection pipe, a water collection tank, a water outlet pipe of the water collection tank and a control unit, wherein thewater collection pipe extends into the water collection tank and the other end of the water collection pipe extends into the adjusting tank; after the other end of the water collection pipe enters the adjusting tank, the water collection pipe extends upwards to a position above a water level of the adjusting tank; a tail section above the water level extends in a bending manner and is communicated with one end of an L-shaped water level adjusting pipe through a rotary connector; the water level adjusting pipe rotates by taking the rotary connector as a shaft under the control of the control unit, so as to adjust the height of an opening end of the water level adjusting pipe; water flow in the artificial wetland flows into the adjusting tank along the water collection pipe and the water level adjusting pipe. According to the automatic water level adjustment system provided by the invention, the water level is dynamically changed, and physical and chemical properties of a wetland environment are improved by utilizing a water level flexible adjusting strategy, so that plants and microorganisms grow better, the water treatment efficiency of the artificial wetland is improved and the water quality of output water of the artificial wetland is ensured.

Description

technical field [0001] The invention relates to the field of constructed wetlands, in particular to a system and method for automatically adjusting the water level of constructed wetlands. Background technique [0002] Constructed wetland is an artificially constructed ecosystem that purifies sewage through the physical, chemical, and biological interactions between wetland plants and microorganisms. It has the advantages of simple structure, low energy consumption, good effluent quality, and easy operation. , low operating costs and other advantages, is a promising sewage treatment technology. [0003] Water level change is an important factor affecting the treatment efficiency of constructed wetlands. Water level, flooding cycle and water level change range will all affect the distribution of plants in the constructed wetland ecosystem, growth strategies, microbial populations and quantities, and physical and chemical properties of the wetland environment. Variety. At pr...

Problems solved by technology

The feedback of the effluent water quality to the water level change period is not considered in the water level regulation of the existing subsurface flow constructed wetland, and the energy efficiency of the automatic water level regulation is not optimized. Moreover, the insufficiently treated water is easily discharged directly during the water level regulation, resulting in poor effluent quality during the water level regulation process.
