Apparatus for simulating slope surface water quality purification experimentation and rainwater wash experimentation

The utility model discloses an apparatus for simulating a slope surface water quality purification experimentation and a rainwater wash experimentation. The apparatus includes a support base plate, base plate pillars arranged on the base plate and a flow deflector tank pivoting on the base plate pillars; and one end of the flow deflector tank is connected with a gradient regulator, a sample arranging unit is disposed on the flow deflector tank above the gradient regulator, a rainwater simulator is disposed above the sample arranging unit, and the rainwater simulator is connected with the flow deflector tank through a height regulator. By adopting the apparatus for simulating the slope surface water quality purification experimentation and the rainwater wash experimentation, an experimentation about various influence factors of slope wash and the slope surface water quality purification experimentation can be smoothly completed in a laboratory, and the simulation can be almost the same as the actual situation;
