Breathing filler and subsurface flow constructed wetland purification system

Abstract

The invention relates to a breathing filler and a subsurface flow constructed wetland purification system. The invention is suitable for the technical field of ecological environment engineering. According to the technical scheme, the breathing filler is provided with a foam floating ball, the outer surface of the foam floating ball is covered with a natural clinoptilolite layer, and the outer surface of the natural clinoptilolite layer is fixed through a steel wire mesh. The diameter of the foam floating ball is 5cm; the particle size of the natural clinoptilolite layer is 0.2-0.3 cm, and the thickness of the natural clinoptilolite layer is 1.5 cm; and D * H of the steel wire mesh is equal to 0.1 cm * 0.1 cm. The subsurface flow constructed wetland purification system is provided with a water inlet control mechanism, a filler well and a water outlet control mechanism, a pebble bearing layer is arranged at the bottom in the filler well, and a water body purification module and a plurality of breathing fillers are arranged in the filler well and above the pebble bearing layer; and a water outlet of the water inlet control mechanism corresponds to an area above the pebble bearing layer in the filler well, and a water inlet of the water outlet control mechanism corresponds to the pebble bearing layer in the filler well.

Description

technical field [0001] The invention relates to a breathing filler and an underflow artificial wetland purification system. Applicable to the technical field of ecological environment engineering. Background technique [0002] Constructed wetland is a ground similar to a swamp that is artificially constructed and operated under control. Sewage is distributed to the artificially constructed wetland in a controlled manner. During the flow of sewage in a certain direction, soil, artificial fillers, plants, and microorganisms are used to A technology for the treatment of sewage by the triple synergy of physical chemistry and biology. [0003] With the in-depth development of my country's ecological environment governance, artificial wetlands have been widely used to treat various types of wetlands due to their simple process, low investment costs, construction and operation and maintenance costs, stable and effective sewage treatment effects, and natural ecology. Sewage, such a...

Problems solved by technology

In engineering applications, it is usually necessary to regularly dredge and clean the artificial wetland filler layer to prevent normal operation due to blockage

The follow-up work due to the plugging of the filler will greatly increase the operation and maintenance cost of the constructed wetland. Therefore, a more flexible operation mechanism of the filler in the constructed wetland is needed to reduce the plugging phenomenon and reduce the operation and maintenance cost.
