Problems solved by technology

[0005] Regarding the use of constructed wetlands to treat sewage, a lot of research has been done at home and abroad, but the main purpose is to build land-based constructed wetlands to purify nitrogen, phosphorus, heavy metals, etc. A large amount of industrial wastewater is injected into the coastal waters along with the city's rivers, and its environmental conditions are closely related to people's lives
At present, the research on remediation of oil-polluted intertidal sediments in coastal wetlands has not been comprehensive and systematic, and there is a long way to go

Abstract

The invention relates to a method for jointly repairing oil-polluted intertidal zone sediments by Spartina alterniflora and microbiome, in which Spartina alterniflora is planted on the oil-polluted intertidal zone sediments, and then inserted into the intertidal zone sediments microorganism. The name of the microorganism: JQ716236, the preservation number CGMCC No.11525, the name of another microorganism: JN999853, the preservation number CGMCC No.11526. Through this experiment link, the present invention confirms the restoration effect of the plants in the Spartina alterniflora artificial wetland system, the indigenous bacteria, the dominant bacteria for petroleum hydrocarbon degradation screened in the research area, the degradation time, and the length of the wetland on the sediments in the oil-polluted intertidal zone .

Description

technical field [0001] The invention belongs to the field of environment, in particular to a method for jointly repairing oil-polluted intertidal zone sediments by Spartina alterniflora and microbiome. Background technique [0002] In the past, most of the research on the decontamination function of constructed wetlands was the nitrogen and phosphorus removal project of domestic sewage. The plants also selected landscape plants such as reeds, cattails and water onions to build constructed wetlands, which not only have the effect of environmental governance but also have landscape value. In practical applications, typical wetland plants or species that can adapt to the special environment of the wetland system are usually selected, such as mangrove (Mangrove), rush (Juncus effusus), and Spartina alterniflora Loisel (Spartina alterniflora Loisel). This paper selects Spartina alterniflora, which grows in the coastal area, is common for many years, has certain ornamental value, ...
