Constructed wetland insulating structure

Abstract

The invention provides a constructed wetland insulating structure. The insulating structure comprises an upper water permeable mulching film, an insulating water permeable brick and a lower water permeable mulching film, wherein the upper water permeable mulching film is arranged under wetland plants, the lower water permeable mulching film is arranged on a constructed wetland substrate, and the insulating water permeable brick is arranged between the upper water permeable mulching film and the lower water permeable mulching film; the water permeable mulching films are non-woven mulching films; and the insulating water permeable brick is a baking-free high-strength light-weight hollow brick. According to the constructed wetland insulating structure, the temperature of each layer of a winter constructed wetland bed body can be effectively improved, and the winter operation effect of the constructed wetland in cold areas can be improved; the water permeable mulching films which are non-woven mulching films have excellent water and air permeating and insulating effects, excellent breathing effect of a plant root system can be maintained, and wetland plants cannot be destroyed; the insulating water permeable brick is prepared by adopting a baking-free method, and is simple in process, low in production cost and low in energy consumption.

Description

technical field [0001] The invention relates to artificial wetland sewage treatment technology, in particular to an artificial wetland heat preservation structure. Background technique [0002] Constructed wetland is an ecological sewage treatment technology, which purifies sewage through the physical, chemical and biological synergy of substrate, plants and microorganisms in the artificially constructed ecosystem. As a natural ecological treatment system, constructed wetlands have the advantages of good effluent quality, low operating costs, energy saving, easy management and maintenance, and good landscape effects compared with traditional sewage treatment technologies. [0003] Temperature conditions are the primary factor affecting the application of constructed wetlands. In cold winter regions, the water flow on the surface of constructed wetlands will freeze. The reduction of water temperature reduces the activity of microorganisms, and the ice layer on the surface o...
