A modular splicing leakage simulation device and method thereof

Abstract

The invention relates to a modularized spliced type leakage simulation device which can be used for carrying out indoor simulation leaching experiments in the field of environment protection research and is suitable for various leaching simulation processes. The modularized spliced type leakage simulation device comprises a peristaltic pump, flow guide pipes, water diversion fluff balls, a sucking pump, a rice planting module, a liquid storage module, a perpendicular leakage module, a side leakage module, a field surface water measuring and sampling module and a rainfall simulation module. The field surface water measuring and sampling module comprises a V-shaped pipe, a runoff collection pipe and the like. The peristaltic pump can control a plurality of hoses to suck leaching solutions from the liquid storage module at a certain flow velocity, and can achieve uniform water distribution through the water diversion fluff balls. All the modules can be freely detached and spliced, various types of rainfall can be simulated, perpendicular leakage water samples of soil layers of different depths, horizontal side seepage of soil of different depths, the soil moisture height and the rice rhizosphere solution can be measured, runoff can be collected, samples of different soil layers can be collected, and the modularized spliced type leakage simulation device has the advantages of being low in running cost and the like.

Description

technical field [0001] The invention belongs to the field of environmental monitoring, and in particular relates to a modular splicing leakage simulation device and a method thereof. Background technique [0002] Agricultural non-point source pollution has the characteristics of randomness, extensiveness, hysteresis, ambiguity, latentness, and difficulty in research and control. The characteristics of soil leaching are directly related to the amount of nitrogen and phosphorus loss in surface runoff, which is very important for the study of water eutrophication caused by agricultural non-point source pollution. Therefore, a comprehensive, simple and easy-to-operate indoor simulated leaching device is very necessary. [0003] At present, some patents relate to soil column simulation devices, but these devices all have certain defects. [0004] For example, the patent titled "Soil Pillar Leaching Device" (application number 201410403212.4, publication number 104215747A) has m...
