Embodiment

[0027] Embodiment: a kind of restoration method of blocked subsurface flow constructed wetland, such as figure 1 , 2 shown, including the following steps:

[0028] Step S1, excavation and transfer

[0029] Excavate and collect the gravel matrix in the area to be cleaned, and transfer it to the feed hopper 1 by a crawler excavator. In order to ensure the drainage performance of the bucket, specifically, the bucket of the crawler excavator adopts a grid bucket, so that during the excavation process of the crawler excavator, the water flows away from the grid bucket, and the gravel matrix remains in the grid. In the bucket, it is convenient to separate the water from the dirt.

[0030] Step S2, preliminary cleaning, screening and transmission

[0031] The gravel matrix entering the hopper 1 is washed with high-pressure water, and the washed gravel matrix is ​​preliminarily screened to obtain large matrix and small and medium matrix. The device is transferred to the drum scre...

Abstract

The invention discloses a restoration method of a blocked subsurface flow constructed wetland, and belongs to the technical field of water treatment, the restoration method comprises the following steps: step S1, excavation and transfer; S2, preliminary cleaning, screening and conveying treatment; S3, further cleaning, screening and conveying treatment, and discharge of the waste; S4, collection and treatment of sewage. According to the method disclosed by the invention, the blocked subsurface flow constructed wetland can be effectively repaired, and the problem that the surrounding environment is easily influenced after the subsurface flow constructed wetland is blocked is solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, more specifically, it relates to a repair method for blocked subsurface flow constructed wetlands. Background technique [0002] According to the way of wastewater runoff, constructed wetlands can be divided into three types: surface flow wetlands, subsurface flow wetlands and vertical wetlands. Subsurface wetlands are the most commonly used types of constructed wetlands. Subsurface wetlands are man-made landscapes that use hydrophilic plants as surface greening and sandy soil as filler to allow water to infiltrate and filter naturally. It has the characteristics of no surface water, small footprint, high utilization rate and convenient maintenance, and is deeply loved by people. [0003] Subsurface flow constructed wetlands have the advantages of good thermal insulation performance, less climate impact, and better sanitation conditions, etc., but their substrates are prone to clogging....
