Abstract

The invention relates to the technical field of artificial wetland sewage treatment, in particular to a simulation test device and test method for phosphorus removal in artificial wetlands. The simulation test device includes a sewage preparation device, a static dissolution device, a dynamic test device, a water outlet device, a detection device, and a controller that sends a start signal to the dynamic test device, water outlet device, and sewage configuration device after setting parameters. The controller sends a signal for detecting the pollutant content in the sewage to the detection device. The test method includes the following steps (1), preparation of test materials (2), preparation of dissolution solution (3), injection of simulated sewage and dissolution solution (4), detection data processing and analysis (5) conclusion and practical application. The invention has low cost and simple operation, and can simulate the adsorption rate of phosphorus in the natural environment to quickly obtain the maximum dissolution amount of calcium ions required in the environment, so as to finally know the required amount of the matrix in the actual environment, and can accurately obtain relevant test data .

Description

technical field [0001] The invention relates to the technical field of artificial wetland sewage treatment, in particular to a simulation test device and test method for phosphorus removal in artificial wetlands. Background technique [0002] Constructed wetland is a ground similar to swampland that is artificially constructed and operated under control. Sewage and sludge are distributed to the artificially constructed wetland in a controlled manner. When sewage and sludge flow in a certain direction, they are mainly used It is a technology for treating sewage and sludge through the triple synergy of physics, chemistry and biology of soil, artificial medium, plants and microorganisms. Its mechanism of action includes adsorption, retention, filtration, redox, precipitation, microbial decomposition, transformation, plant shading, residue accumulation, transpiration of water and nutrient absorption, and the action of various animals. [0003] Constructed wetlands (CWs) technol...
