Embodiment 1

[0017] A sewage treatment method in a constructed wetland, the specific steps of the sewage treatment method are: firstly establish a first-level sewage treatment system, and set emergent plants with well-developed root systems and a filter matrix at the entrance of the constructed wetland, and the filter matrix includes melon seeds, limestone Or volcanic rock, laid in layers, the particle size becomes smaller from bottom to top; establish an aquatic animal system in the artificial wetland lake area.

[0018] Secondly, the sewage treatment method also includes the establishment of a secondary sewage treatment system, that is, the establishment of an aquatic animal system and the arrangement of plants at the entrance of the constructed wetland. The aquatic animal system includes breeding filter-feeding fish, carnivorous fish and filter-feeding bottom animals. Feeding fish include any one or a combination of two or more of mandarin fish, black snakehead, squid, bighead carp, and ...

Abstract

The invention discloses a constructed wetland sewage treatment method, which comprises the following steps of firstly building a first-stage sewage treatment system; setting emergent aquatic plants with developed root systems and filtering material substrates in an entrance position of a constructed wetland, wherein the filtering material substrates comprises melon seeds, limestone or rhyolite, and are laid in layers, and the particle diameters are reduced from bottom to top; building an aquatic animal system in a constructed wetland lake region. The scientific and reasonable combined mode design, the seasonal biocoenosis configuration, high-absorption performance substance material selection and landscape science theory application are used; the COD and BOD removal rate is improved; the capability of eliminating N, P and other toxic elements can also be enhanced.

Description

technical field [0001] The invention relates to a sewage treatment method, in particular to a sewage treatment method in an artificial wetland. Background technique [0002] The known sewage treatment methods in constructed wetlands include: surface flow constructed wetland, sewage flows through the surface of the constructed wet soil, the water depth is relatively shallow, and the removal of organic pollutants is achieved through the interception of wetland plant rhizomes and the degradation of biofilms on rhizomes As a result, the surface flow constructed wetland project is cheap and easy to operate and manage, but the treatment efficiency of pollutants is low, it is easy to generate odor, the sanitation condition is poor, and the floor area is large; the subsurface flow constructed wetland, the sewage flows through the surface of the constructed wetland, The interception effect of the filler is improved, the moisturizing performance is good, the factors affected by the cl...
