Abstract
The utility model discloses a laboratory-simulated rainfall system for a storm runoff pollution source. The laboratory-simulated rainfall system comprises a water supplying device, a simulated rainfall device and a simulated experimental device. The simulated experimental device comprises three unit cavities with opening upper ends, and a surface runoff liquid receiving tube for and a infiltration liquid receiving tube are arranged on the side wall at the tail end of each unit cavity. The simulated rainfall device comprises nozzles and a bracket, wherein, the bracket is arranged above the three unit cavities, the nozzles are fixed on the bracket, and at least one nozzle is arranged at the center top part of each unit cavity. The water supplying device comprises a water pool, a water pump and water pipes, wherein, the water pipes are connected with the nozzles. Each of the three unit cavities consists of a glass box body with an opening and two glass partition boards. The simulated rainfall system can take various soils with different earthiness types for experiments, and can be applied to the research on the pollution mechanism and the loss law of nutrients such as nitrogen and phosphorus, pesticides and other organic or inorganic pollution materials.
