In conclusion, it is obvious that the novel biomembrane filler has a significantly better effect on removing pollutants in river water than the prior art.
Performing experiments on the 5 kinds of sewage with different properties, and recording data of removal rate; as is evident from the above fig. 2-16, the removal rate of the novel carrier filler is far higher than that of the filler carriers configured by the other two conventional methods; the novel carrier filler is illustrated. The specific reasons mainly include that the novel biological membrane filler has large surface area and strong adsorption capacity, and can simultaneously absorb microorganisms, bacteria and required nutrients: ammonia nitrogen, COD, etc.; the microbial bacteria proliferation and fission speed on the surface of the biological membrane is accelerated, and the pollutant in the sewage is removed quickly, so that the biological membrane growing on the rough surface of the biological membrane is thicker and larger than others, and is shown in sewage treatment: the discharged water is clear, and all discharge indexes accord with the discharge standard of national regulation.
The principle and the implementation mode of the invention are explained by applying specific embodiments in the invention, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
