Problems solved by technology
[0004] However, the existing flume simulation experiments are mostly used to simulate water conditions such as lakes and rivers. There are huge differences in physical and chemical conditions, water quality characteristics, and microbial communities between natural water bodies and saline-alkali seepage water, which makes it impossible to further explore the water quality improvement and utilization of seepage water. measures, which pose a significant obstacle to the fishery utilization of saline-alkaline water and soil resources

Abstract
The invention relates to a test device for simulating the production process of secondary saline-alkali water, comprising a test tank and a support, the test tank is arranged on the support, the bottom tank is located at the bottom of the test tank, and trapezoidal saline-alkali soil filling tanks are symmetrically distributed on both sides of the test tank , the water storage tank is located above the trapezoidal saline-alkali soil filling tank, and the inverted trapezoidal water tank is located between the trapezoidal saline-alkali soil filling tank and the water storage tank on both sides. Slot plate between saline-alkali soil filled tanks, channel plate between trapezoidal saline-alkali soil filled tanks of each layer, channel plate between trapezoidal saline-alkali soil filled tank and bottom water tank, and chute plate between trapezoidal saline-alkali soil filled tanks of each layer and inverted trapezoidal water tank Water permeable holes are respectively opened on the top, sampling holes are provided on the outer wall of the trapezoidal saline-alkali soil filling tank of each layer, and outlet pipe valves are provided on the bottom tank. The invention can simulate the formation environment of reducing saline-alkali water, and can conduct relatively comprehensive research on the attenuation mechanism of saline-alkali soil pollutants and water quality control.
Description
technical field [0001] The invention belongs to the technical field of secondary saline-alkali water quality control research, and in particular relates to a test device for simulating the production process of secondary saline-alkali water. Background technique [0002] The fishery utilization of abandoned saline-alkali water resources is an important way to expand the area suitable for fishing, improve the ecological environment, and achieve targeted poverty alleviation for local residents. However, the concentration of pollutants such as nitrogen and phosphorus in the low-lying secondary saline-alkaline water environment is too high, and there is a lack of effective control measures. This is a great bottleneck restricting the development and utilization of saline-alkali water resources and fisheries. [0003] Compared with the traditional soil column experiment, the flume simulation experiment has a two-dimensional flow direction, and can observe the pollutant conversion ...
