Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.
Fig. 1 shows a schematic structural diagram of a system for reducing pollution of a drain outlet of a river or lake according to an embodiment of the present invention. The utility model discloses an embodiment provides a system for reducing river course or lake drain pollutant, as shown in FIG. 1, this system for reducing river course or lake drain pollutant can include:
the soft partition 1, the soft partition 1 can separate out the working water area along the river bank or lake bank, the working water area covers the drain A;
the plurality of floating cylinders 2 are connected with the soft partition 1, and the plurality of floating cylinders 2 provide supporting force for the soft partition 1 so that the soft partition 1 is erected in the working water area;
the fixing blocks 3 are used for further fixing the soft partition 1;
the aquatic plant 4 is arranged by taking the sewage discharge outlet A as a center, so that a plant absorption zone is formed, and the ammonia nitrogen and the total phosphorus in the sewage discharged from the sewage discharge outlet A are primarily reduced;
the biological filler 5 is arranged in the working water area, and microorganisms are attached to the biological filler 5 and can perform biological reaction with the sewage to reduce COD, BOD and ammonia nitrogen in the sewage.
The utility model discloses an embodiment provides a system for reducing river course or lake drain pollutant separates the work waters through soft wall 1 in river course or lake, uses drain A to be provided with aquatic plant 4 in order tentatively to reduce ammonia nitrogen, total phosphorus in drain A exhaust sewage as the center in the work waters to it carries out biological reaction in order to further cut COD, BOD, the ammonia nitrogen in the sewage to be provided with biofilm carrier 5 and sewage.
