Cover layer structure optimization method for adjusting refuse landfill percolation through plant dissipation

Abstract

The invention discloses a cover layer structure optimization method for adjusting refuse landfill percolation through plant dissipation. The method comprises the steps that S1, a test zone is designed, wherein the test zone includes a plant coverage test zone and a comparison test zone; S2, actually measured data is acquired, including water balance element data, physical and hydrodynamic parameters of a cover layer and physiological parameters and meteorological observation data of plants; S3, the dynamic variation rules of water balance elements of the cover layers of plant covered test zones are analyzed; S4, according to the acquired water balance element data and physical and hydrodynamic parameter data, a Hydrus2D numerical simulation method is adopted to simulate the percolation control effects of the cover layers in design scenes; S5, the percolation control effects of the cover layers in the design scenes are analyzed, and an optimum cover layer structure is determined through comparison. The percolation control effects of the cover layers in different design scenes are analyzed by combining the actually measured data and numerical simulation, and accordingly cover layer structure optimization is achieved.

AI Technical Summary

Benefits of technology

The technical effects described by this patented method are that it allows for precise testing of plants' covering layers while also analyzing their moisture-related behavior during rainwater runoff or other environmental conditions such as heat stress. This helps identify issues related to excessive rainfall or snowfall impacts on crops grown indoors.

Problems solved by technology

This patented technical solution describes how environmental concerns are caused by leakages during urban solid wastes management due to poorly designed buried litter systems used for temporary liquid containments. These issues include increased risk of contamination underground waters, potential damage to sensitive infrastructure like roads near populated regions where there may exist hazards related to excess rainwater runoff. To address these challenging situations, researchers conducted experiments at different locations around the world aimed towards developing effective measures against leaks without causing harmful effects upon nearby landscape environments.
