AI Technical Summary

Technical Problem

When using existing microbial remediation wetland purification devices, the frame of the composite filler is an integral structure, which is inconvenient to lay and replace. Furthermore, the composite filler expands after being immersed in water, making it difficult for the geotextile to cover tightly and causing it to easily break.

Method used

The design incorporates a bottom frame and a support frame, along with limiting sleeves, limiting plugs, connecting components, and traction ropes. Through the cooperation of elastic buckles and compression springs, it enables quick disassembly and installation, ensuring tight coverage and stability of the composite filling module.

Benefits of technology

It improves the filling and replacement efficiency of composite fillers, prevents geotextile breakage, and enhances the reliability and ease of operation of the device.

Abstract

This invention provides a microbial remediation wetland purification device, relating to the field of ecological restoration and governance technology. It includes: a bottom frame, which is a rectangular cavity structure with a supporting frame at the top; two connecting components on each side of the bottom frame; and a mounting frame that can drive a first geotextile to slide up and down along a channel for adjustment. Utilizing the elasticity of a buffer spring, it ensures that the first geotextile tightly covers the composite filling module when it expands after immersion, improving the reliability of the composite filling module. This invention solves the problems of existing microbial remediation wetland purification devices, where the frame for placing the composite filling material is usually a single structure, making it cumbersome to lay and replace the composite filling material. Furthermore, the composite filling material expands after immersion in water, making it difficult for the surface geotextile to tightly cover it, and excessive expansion can easily lead to the surface geotextile cracking.
