By planting different kinds of plants, the landscape effect of presenting plant characters or plant patterns can be realized.
When the suspended filler is applied to the polluted water body, indigenous microorganisms in the polluted water body and the bottom mud are attached to the filler, and the microorganisms are continuously enriched, cultured and domesticated to enable functional microorganisms to form a film on the filler. The biological film formed by the microorganism attached to the surface of the filler is contacted with the polluted water body, and the microorganism attached to the film takes organic matters in the ingested sewage as nutrient substances and converts the nutrient substances into substances required by self growth or inorganic matters through a metabolic process, thereby achieving the effect of purifying the water quality. The surface of the filler forms a microenvironment consisting of anaerobism, anoxia, aerobiosis, protozoa and algae. After a period of time, the aged microbial film attached to the outer layer of the filler falls off under the action of the shearing force of water flow, and a new biological film gradually forms an anaerobic-anoxic-aerobic layer, so that the self-renewal of the biological film is formed, and the continuous purification effect of the polluted water body is realized.
When the fixed filler is applied, the filler can be selected from gravel, zeolite or immobilized microorganism carriers and the like. If the fillers such as zeolite are adopted, the filler can better adsorb ammonia nitrogen and other pollutants, and microorganisms can be attached to the surface of the filler, so that a growth space is provided for the microorganisms. If the immobilized microorganism carrier is adopted to embed microorganism strains with the pollutant degradation function in the porous carrier, microorganisms can propagate in the carrier, and small molecules and reaction metabolites can freely enter and exit the porous carrier, so that the pollutants can be removed by the microorganisms.
In a word, the invention has the function of purifying the polluted water body, has the landscape effect and has far lower operation cost than the conventional treatment technology. The module and the system provided by the invention have simple structure, are convenient to assemble, disassemble, transport, operate and maintain, have better purification effect when being applied to low-flow-rate or static polluted water bodies, do not need power, and do not need to add chemical agents.

Geotextile is arranged in the planting groove, and ceramsite or immobilized microorganism or other fillers are filled in the geotextile. The pollutant purification characteristics are combined in the planting tank, plants are selected according to local conditions, and the ornamental effect is also reflected. On the premise of the implementation of a river-following sewage interception project, after the project is implemented for 3 months, the water quality of the river channel basically eliminates black and odorous substances, the water quality data gradually changes, the water environment of the river channel is obviously improved, and the water quality of the downstream section of the river channel can be improved to the V-type level.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
