The invention discloses an experimental device and method for on-site simulation and control over adsorption of aquatic organisms on the inner walls of pipelines, and belongs to the field of ecological hydraulics. By installing the experimental device on an experimental field, growth and adsorption characteristics of the aquatic organisms in a water area on the inner walls of the experimental pipelines can be simulated, and the inhibition effect of a test reagent on the growth and adsorption effects of the inner walls of the aquatic organism pipelines is tested. The device mainly comprises a water supply system for providing experimental water, a front tank for stabilizing water flow, the experiment pipelines for experiments, a tail water tank for stabilizing outlet water flow of the pipeline, a measuring and controlling instrument for measuring the flow speed of the experimental pipelines and the front-back pressure difference of the experimental pipelines, a dosing system for addingthe test reagent, a drainage pipeline for discharging the experimental water and the like. In the device, particularly, the two experimental pipelines are provided with static mixers, and the dosing system is used for conveying the test reagent to the water flow of the experiment pipelines. A using method of the device is simple, convenient to use, practical and reliable, can be popularized to simulation experiments of growth habits of the aquatic organisms and inhibition measures.
Description
technical field [0001] The invention belongs to the field of ecological hydraulics, and relates to an experimental device and method for on-site simulation and prevention and control of the adsorption of aquatic organisms on the inner wall of a pipeline. Background technique [0002] In the water pipeline system, aquatic organisms and their young eggs in the water flow will stay, grow and reproduce on the inner wall of the flow pipeline, causing biofouling of the flow pipeline. This phenomenon will bring the following aspects Harm: (1) reduce the cross-sectional area of the flow pipeline, increase the roughness of the pipeline wall, and reduce its flow capacity; (2) cause corrosion of the pipeline wall, affecting the structural strength and durability of the pipeline; (3) Pollutants produced by accumulating biological excrement and rotting corpses will deteriorate the quality of the treated water. The above-mentioned problems will reduce the operating efficiency of the wa...
