Simulation test device and test method for artificial wetland dephosphorization

Abstract

The invention relates to the technical field of artificial wetland sewage treatment, in particular to a simulation test device and test method for artificial wetland dephosphorization. The simulationtest device comprises a sewage preparation device, a static dissolution device, a dynamic test device, a water outlet device and a detection device, and further comprises a controller sending a startsignal to the dynamic test device, the water outlet device and the sewage preparation device after parameters are set, and after water outlet is completed, the controller sends a signal detecting thecontent of pollutants in sewage to the detection device. The test method comprises the following steps of (1), preparation of a test material; (2), preparation of a dissolution solution; (3), simulation of the injection of the sewage and dissolution solution; (4), processing and analysis of detected data; (5) conclusion and practical application. The simulation test device and test method for theartificial wetland dephosphorization have the advantage that the cost is low, the operation is simple, the adsorption rate of phosphorus in the natural environment can be simulated to quickly obtain the maximum dissolution amount of calcium ions required in the environment to finally know the required amount of a matrix in the actual environment, and the relevant test data can be accurately obtained.

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...
