Embodiment

[0020] Take out the partition plate 5 from the slot 4, and according to the volume of a soil holding area 7, use a soil tool to cut out the same volume of undisturbed soil and put it into the soil holding area 7 at the end of the water outlet 9, and remove the foreign matter in the slot 4. 5 Insert and seal the gap with raw tape to avoid water leakage from the gap; use the same method to load undisturbed soil in another soil holding area 7. Place the support arms 8 on both sides on the fixed object, and prop up the bottom 2 at the rear end of the tank body 1, so that the slope of the box body is consistent with the actual slope. A water container is placed at the water outlet 9, and the test water is injected into the water injection tank 3. Observe the state of seepage of water from the soil, and adjust the dividing plate according to the actual situation to change the diameter and quantity of the seepage holes 6, so that the water can flow out after infiltrating all the soil...

Abstract

The invention provides a simulation test device for obtaining soil interflow and belongs to the research field of water pollution control. A raw material for manufacturing the device is polyethylene glycol terephthalate resin, which is used in quantity in production of beverage bottles at present and will not pollute interflow. The device adopts a segregated design, and volume of a soil containing area is reduced so as to put undisturbed soil of the same volume therein at a time. As separator plates are detachable, it is convenient to put undisturbed soil, and interference with soil structure is minimized. Diameter and number of water seepage holes in the separator plates are replaceable, and it is guaranteed that water infiltrates from upper soil layer and completely flows through soil. The device of the invention can simulate slope of an actual slope surface.

Description

technical field [0001] The invention relates to the research field of water pollution prevention and control, in particular to a simulation test device for obtaining soil flow in soil. Background technique [0002] Rural non-point source pollution refers to dissolved or solid pollutants in rural life and agricultural production activities, such as organic or inorganic substances such as soil particles, nitrogen, phosphorus, pesticide heavy metals, rural poultry manure and domestic garbage in farmland , from a non-specific area, under the action of precipitation and runoff erosion, through farmland surface runoff, farmland drainage and underground seepage, a large amount of pollutants enter the receiving water body and cause pollution. The generation and discharge of this kind of pollution still have a tendency to increase, and it has the characteristics of dispersion and concealment, randomness and uncertainty, difficulty in monitoring and spatial heterogeneity, so the press...
