Embodiment 1
[0016] Embodiment 1: a kind of method that is applied to river ecosystem to control water body pollution, adopts the method that biofilm method and physical adsorption method combine to control water body pollution, comprises the following steps:
[0017] In the first step, a combined sewage treatment system is composed of a biological contact oxidation treatment device and a physical adsorption treatment device; in the second step, the combined sewage treatment system is placed in a river water body. Among them, the biological contact oxidation treatment device is made of ceramsite with a particle size of 3mm through high-concentration sewage artificially -3-
[0018] It is made by inoculating hanging film, and then acclimating high-, medium-, and low-concentration sewage and bagging. The physical adsorption treatment device is made by mixing 10 parts by mass of sand and 1 part by mass of clay and bagging.
[0019] Among them, the biological contact oxidation treatment de...
Embodiment 2
[0037] Embodiment 2: A kind of method that is applied to river ecosystem to control water body pollution, adopts the method that biofilm method and physical adsorption method combine to control water body pollution, comprises the following steps: the first step, biological contact oxidation treatment device and a The physical adsorption treatment devices are jointly formed into a combined sewage treatment system; in the second step, the combined sewage treatment system is placed in a river water body. Among them, the biological contact oxidation treatment device is made of ceramsite with a particle size of 3 mm, artificially inoculated with high-concentration sewage, and then bagged after domestication of high-, medium-, and low-concentration sewage. The sand and kaolin are evenly mixed and bagged at a weight percentage of 1:1. The sand for construction projects has more than 90% of the particles with a particle diameter greater than 1mm, and the kaolin has more particles with ...
