A restoration system and restoration method for constructed wetland

Abstract

The invention relates to a restoration system and restoration method for constructed wetlands, comprising: a repair pipe, a confluence channel, and a fixing plate for fixing the repair pipe and the confluence channel; at least one confluence channel is arranged on the fixation plate, and the confluence channel There are several repair pipes arranged at intervals on the outer side, and several plugs are arranged on the repair pipes; an inner pipe is movably connected to the inner side of the repair pipe, and the inner pipe can rotate, and a repair liquid is arranged inside the inner pipe, so There are several slow-release holes on the outer wall of the inner tube; when the inner tube is rotated, the plug on the repair tube can block the slow-release holes on one side of the inner tube, so that the repair liquid flows toward the repair tube side. Sustained release; the restoration fluid is collected to the outside of the confluence channel after the restoration of the wetland, and is drawn out of the restoration system through the confluence channel.

Description

technical field [0001] The invention relates to a repair system, in particular to a repair system and a repair method of an artificial wetland. Background technique [0002] Soil is an important natural resource for human survival and agricultural production. Due to the characteristics of strong toxicity and easy enrichment of heavy metals, the pollution of heavy metals to soil is difficult to recover in a short period of time. The soil in some areas is polluted by heavy metals. The heavy metal content of the crops growing on it exceeds the standard, which affects human health. Caohai is the largest natural freshwater lake in Guizhou. It is not only a typical plateau wetland ecosystem, but also an important national nature reserve. Sequential discharge, random dumping of household garbage, and extensive use of pesticides and fertilizers have led to increasingly serious soil environmental pollution around Caohai. [0003] The current solution to the repair of artificial wetl...

AI Technical Summary

Problems solved by technology

[0003] The current solution to the repair of artificial wetlands not only wastes manpower and material resources, the repair effect is not good, but also easily causes secondary pollution of the soil. When performing wetland restoration, drilling operations are required for each repair, which is time-consuming and laborious, and the restoration solution is not Quantitative and uniform release will easily lead to waste of repair fluid. After multiple repair pipes are repaired, the mixed liquid cannot be collected outside the confluence channel and extracted through water pipes. Large-scale restoration of constructed wetlands cannot be realized, and the practicability is not strong.
