A detachable variable water level vertical flow constructed wetland

Abstract

The invention relates to a detachable variable-water-level vertical-current artificial wetland which comprises a high water level tank (10), a wetland tank (20), an air pipe (30), a water collection pipe (40) and a base (50), wherein the bottom of the high water level tank (10) is connected with a water inlet pipe (101); the water inlet pipe (101) is connected with a surface water distribution pipeline of the wetland tank (20); the tank wall is spliced by PVC (polyvinyl chloride) boards; the air pipe (30) is arranged at the middle part of the wetland tank (20); the top end of the air pipe (30) is communicated with air; the water collection pipe (40) is positioned on the bottom of the wetland tank (20); one end of the water collection pipe (40) is connected with a water outlet pipe (402); and the top end of the water outlet pipe (402) is connected with a rotary bent pipe (403). By adopting the detachable mode for splicing and construction, the artificial wetland has the advantages of simple structure and favorable treatment effect, is convenient to install, can reutilize the land, and effectively achieves the goals of material reutilization and waste reduction.

Description

Technical field: [0001] The invention relates to the field of constructed wetlands, in particular to a detachable variable water level vertical flow constructed wetland. Background technique: [0002] At present, most of the pool walls of constructed wetlands are built with brick-concrete structures, and the fillers are mainly laid layer by layer in the form of manual handling according to the water quality required and the target water quality after treatment. During the laying process, Slow speed, heavy manual workload, long construction period, and gradation quality cannot be guaranteed; after the construction of the constructed wetland, especially in the initial stage of operation, due to the fixed water level, there is no good way to control the change of the water level, let alone control the water level To stimulate the plant roots to extend to the bottom of the wetland, it is also inconvenient to realize the alternating dry and wet transportation mode; during the ope...

Problems solved by technology

[0002] At present, most of the pool walls of constructed wetlands are built with brick-concrete structures, and the fillers are mainly laid layer by layer in the form of manual handling according to the water quality required and the target water quality after treatment. During the laying process, Slow speed, heavy manual workload, long construction period, and gradation quality cannot be guaranteed; after the construction of the constructed wetland, especially in the initial stage of operation, due to the fixed water level, there is no good way to control the change of the water level, let alone control the water level To stimulate the plant roots to extend to the bottom of the wetland, it is also inconvenient to realize the alternating dry and wet transportation mode; during the operation of the wetland, if the air pipes, water collection pipes are damaged, or the artificial wetland is blocked, etc., it needs to be repaired. It is very difficult and time-consuming to dig out, clean, classify the filler or replace the blocked filler and damaged pipes, and it may damage the internal structure of the wetland; in addition, the location of the sewage treatment system in the constructed wetland changes, and the scale of the wetland Expansion or change, when the site of the sewage treatment system has other uses, the original wetland system will be abandoned, which will inevitably cause a large amount of solid waste, pollute the environment, and cause a great waste of resources, so a detachable variable-scale wetland system is designed. Constructed wetlands are very beneficial if the water level flows vertically
