Embodiment 1
[0026] Such as figure 1 As shown, a method for removing COD, ammonia nitrogen and suspended solids in rainwater includes an inlet pump 1, a multi-layer filter 2 and a drainage pump 7, and the output end of the inlet pump 1 and the input end of the multi-layer filter 2 pass through Pipeline connection, the output end of the multilayer filter 2 is connected with the input end of the drainage pump 7 through a pipeline, and the inside of the multilayer filter 2 is filled with a gravel layer 3, a modified iron slag layer 4, and a modified iron slag layer from bottom to top. Concave-convex soil layer 5 and quartz sand layer 6, gravel layer 3, modified iron slag layer 4, modified concave-convex soil layer 5 and quartz sand layer account for 4%, 50% and 50% of the total volume of multi-layer filter 2 respectively. 42% and 4%, the gravel apparent density of gravel layer 3 is 2510kg / m 3 , the particle size is 100 mesh, the preparation process of the modified iron slag in the modified i...
