Embodiment Construction

[0013] The specific embodiment of the present invention is as figure 1 shown.

[0014] In this example, a method for grading wetland fillers added with nano-carrier materials, layered filling is adopted from bottom to top, and zeolite layer 3, nano-modified ceramsite layer 2 and vermiculite layer 1 are filled in sequence; the filler particle size is from bottom to top become smaller in turn; the filling height of zeolite layer 3, nano-modified ceramsite layer 2 and vermiculite layer 1 is 1;1:1. The layered fillers are respectively filled into the layered sieves, the zeolite in the zeolite layer 3 is filled in the zeolite layer filling screen 4, the nano-modified ceramsite in the nano-modified ceramsite layer 2 is filled in the nano-modified ceramsite layer In the filling screen 5 , the vermiculite of the vermiculite layer 1 is filled in the vermiculite layer filling screen 6 .

[0015] In this embodiment, the particle size of the nano-modified porous ceramsite is 1.5-2.5 cm,...

Abstract

The invention discloses a grading method of a wetland padding added with a nano-carrier material. A zeolite layer (3), a nanometer modified ceramsite layer (2) and a vermiculite layer (1) are filled hierarchically in sequence from bottom to top; the particle size of the padding becomes smaller in sequence from bottom to top; the filling height ratio of the zeolite layer to the nanometer modified ceramsite layer to the vermiculite layer is 1 to 1 to 1. A delamination sieve is filled with a hierarchical filling material, a zeolite layer filling screen (4) is filled with zeolite of the zeolite layer (3), a nanometer modified ceramsite layer hierarchical filling screen (5) is filled with nanometer modified ceramsite of the nanometer modified ceramsite layer (2), and a vermiculite layer filling screen (6) is filled with vermiculite of the vermiculite layer (1). The artificial wetland padding is filled hierarchically from bottom to top, and the particle size of the padding becomes smaller in sequence from bottom to top, so that the probability of blockage of an upstream vertical flow wetland can be lowered, a substrate can be flushed successfully, and a good flushing effect is achieved in a back-flushing process.

Description

technical field [0001] The invention relates to a method for grading wetland fillers added with nano carrier materials, which belongs to the technical field of environmental protection. Background technique [0002] Constructed wetlands are based on the ecological principles of natural wetlands, and artificially control the factors that play a role in purification, such as substrates, plants and microorganisms, so as to realize the removal of pollutants in sewage, and can be popularized and applied in practical projects. New sewage treatment system. Constructed wetlands are generally classified as surface flow wetlands. Subsurface flow wetlands, vertical flow wetlands, and vertical flow constructed wetlands have gradually shown advantages due to their relatively small footprint, advanced technology, high efficiency and energy saving, low investment, and low operating costs. [0003] The removal of nitrogen, phosphorus and organic pollutants in water by the vertical flow we...
