Abstract

The invention relates to a device and method for simulating the phosphorus migration and transformation of underground water in a riverside zone. The simulation device is mainly composed of a water supply device, a seepage tank and an artificial rainfall device, the water supply device comprises a water storage column and a balance water column, and the seepage tank is divided into a water inlet area, a water-containing medium area and a water outlet area which are arranged at intervals; a water-containing layer is arranged in the water-containing medium area, and a perforated glass tube simulation well connected with a peristaltic pump is placed in the water-containing medium area; the side wall of the water-containing medium area is provided with a plurality of measurement sampling ports, and the water outlet area is provided with a height-adjustable overflow pipe; the upper part of the water outlet area is connected with a water storage tank connected with an aerator, the bottom of the water inlet area is connected with a balance water column through a water pipe, and a valve is arranged on the water pipe; the upper part of the water inlet area is connected with the aerator, and a water inlet pipe of the artificial rainfall device can control the rainfall supply intensity of each supply source. The device and the method can objectively simulate the riverside zone underground water-surface water interaction and phosphorus migration and transformation process, and the teaching demonstration of the riverside zone underground water seepage and pollutant migration learning by teachers is facilitated.

Description

technical field [0001] The invention belongs to the technical field of water environment protection, and in particular relates to a simulation device and a simulation method for groundwater phosphorus migration and conversion in a riverside zone, which are used for teaching and demonstration of groundwater seepage and pollutant migration in a riverside zone. Background technique [0002] Phosphorus is a key element to limit the eutrophication of water bodies, and eutrophication caused by phosphorus pollution in water bodies has always been a hot issue in the field of water environment protection. The "Water Ten Measures" specifically pointed out that in the process of watershed pollution prevention and control, targeted measures should be taken against total phosphorus pollutants. As a channel for groundwater to discharge to surface water, the riparian zone has a strong interaction between surface water and groundwater. It is not only a mixed area of ​​various water sources,...
