Embodiment Construction
[0023] This example is carried out in a simulation device. Ditch water samples were taken for the sewage used in the experiment.
[0024] Experimental process and conditions: the position of the experimental tank is high or low to simulate the drop of the river slope, and it flows into the lower experimental tank by itself. After entering the sediment tank with agitator and overflowing through the absorption and percolation of aquatic plants, it is sealed and pumped into the storage tank under negative pressure. The water bottle then naturally drops into the experimental cylinder at the same speed; during the experiment, the fluorescent lamp is used to irradiate light according to the natural light-dark ratio; there is a two-stage percolation of PFU (polyurethane foam block) A inside, and its function is to make the micro organisms therein active. A living space for decomposing pollutants; the same kind of aquatic plants are planted in the sedimentation tank, and the same numb...
