Abstract

The invention relates to a water inlet treatment device for a constructed wetland system and a method thereof, and particularly relates to an incoming water pretreatment device for a constructed wetland system and a method thereof. The device comprises a square pipeline, wherein a filling layer is arranged at the bottom of the square pipeline, and is two thirds as high as the square pipe; the filling layer is divided into a physical filter layer and an earthworm filter layer from bottom to top; a round vent is formed right above the square pipeline. According to the method, after the device is applied to a grating and a grit chamber, sands and large particles in sewage are removed, and the sewage enters a sewage delivery pipeline of the device and flows through the earthworm filter layer and the physical filter layer in the delivery process, so that organic matters and solid pollutants in the sewage are further purified.

Description

technical field [0001] The invention relates to a water inlet device and method for a constructed wetland system, in particular to a water inlet pretreatment device and method for a constructed wetland system. Background technique [0002] As the main sewage ecological restoration technology, constructed wetland is widely used to treat various forms of sewage due to its ecological and environmental friendliness. [0003] At present, the constructed wetlands used at home and abroad generally have the disadvantage of insufficient long-term operation stability of the system (that is, the pores of the planting bed are easily blocked). The main reason is the insufficient removal of suspended solids in the water during the pretreatment process or the compaction of the planting bed medium caused by plant root exudates. Currently commonly used pretreatment facilities include sedimentation tanks, anaerobic reactors (such as anaerobic baffle reactors and downflow anaerobic suspended ...
