[0020] like Figure 1 and Figure 2 As shown, a high-porosity three-dimensional space emission type denitrification rope filler structure disclosed by the utility model is used to improve the efficiency of biological denitrification. The filler of the utility model can be applied to the prevention and treatment of eutrophication and algae outbreaks in rivers and lakes. In the past, it was best used in summer in lakes and reservoirs with serious blue algae blooms.

[0021] The high porosity three-dimensional space emission type denitrification rope packing structure comprises an upper fixing plate 1, a lower fixing plate 2, a pillar substrate 4 and a fiber pillar material 6. The upper fixing plate 1 and the lower fixing plate 2 are parallel to each other and are used to provide a three-dimensional space.

[0022] A plurality of pillar substrates 4 are used, and a plurality of fixing grooves 3 matching the number of pillar substrates 4 are respectively provided on the opposite surfaces of the upper fixing plate 1 and the lower fixing plate 2; the two ends of the pillar substrate 4 are respectively arranged in the fixing grooves 3 of the upper fixing plate 1 and the lower fixing plate 2, and a plurality of pillar substrates 4 are vertically arranged in parallel between the three-dimensional space formed by the upper fixing plate 1 and the lower fixing plate 2.

[0023] A plurality of fiber column material fixing disks 5 are connected in series on each pillar substrate 4, and a plurality of fiber column materials 6 are dispersed around the fiber column material fixing disk 5 with the fiber column material fixing disk 5 as the center of the circle, for providing an emission type denitrification rope filler. In this embodiment, the fiber column material 6 and the fiber column material fixing disk 5 are both made of polyvinyl chloride.

[0024] Furthermore, in order to increase the density of the fiber column material 6 in the three-dimensional space, in the present embodiment, the thickness of the fiber column material fixing disk 5 is 2-3 cm, and the fiber column material 6 is respectively distributed in an radiating manner on the circumference of the top surface and the bottom surface of the fiber column material fixing disk 5 with the top surface and the bottom surface of the fiber column material fixing disk 5 as the center.

[0026] The working principle of the utility model is as follows:

[0027] The utility model installs an emission-type denitrification rope filler in a three-dimensional space with high porosity. The filler combines the advantages of two biodegradable polymers, polyhydroxyalkanoates (PHAs) and polylactic acid (PLA). By accurately controlling the component ratio, the content of inorganic filler and the use of foaming agent, an emission-type denitrification rope filler is made, and effective control of the sustained-release rate of the effective ingredients of the filler is achieved. At the same time, by optimizing the density and porosity of the material and the emission shape, the surface area of ​​the filler is increased and the attachment of microorganisms is improved.

[0028] Within 15-25 days of addition, the main water quality indicators such as COD, TN, TP, turbidity, etc. can be improved from the inferior V class to the IV class level (GB 3838-2002). The relative abundance of denitrifying microorganisms can be increased from less than 5% to more than 10%. The expression of NapA, the periplasmic nitrate reductase of denitrifying bacteria, is increased by 5 times (in log2FC), and the expression of NapB is increased by 4 times. Compared with ordinary fillers, this high-porosity three-dimensional space emission-type denitrification rope filler can increase the biological denitrification efficiency by 10 times. The utility model installs an emission-type denitrification rope filler in a high-porosity three-dimensional space, and through the density and porosity of the fiber column material and the emission shape; the surface area of ​​the filler is increased, the microbial attachment is improved, and it has the characteristics of high total nitrogen removal efficiency in low-concentration water bodies. In addition, this filler can effectively enrich functional denitrification functional bacteria and realize the rapid and stable formation of biofilm.
