Abstract

The invention relates to a method for jointly repairing oily wastewater by Spartina alterniflora and microorganisms. Spartina alterniflora is planted in oil-polluted soil, and then microorganisms are inserted into the soil. The name of the microorganisms is JQ716236, and the preservation number is CGMCC No. 11525, date of deposit on October 21, 2015, classification name: Vibrio sp. deposit unit: China Microbiological Culture Collection Management Committee General Microbiology Center, address: No. 3, Yard 1, Beichen West Road, Chaoyang District, Beijing. Through this experimental link, the present invention has confirmed the effects of plants, native bacteria, dominant bacteria for petroleum hydrocarbon degradation screened in the research area, degradation time, and wetland length in the constructed wetland system of Spartina alterniflora on the total petroleum hydrocarbon (TPH) in oily wastewater. Removal.

Description

technical field [0001] The invention belongs to the field of environment, in particular to a method for jointly repairing oily wastewater by Spartina alterniflora and microorganisms. 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, Juncus effusus and Spartina alterniflora Loisel. In this paper, Spartina alterniflora, which grows in the coastal area, is common for many years and has certain ornamental value, is selected as an experimental plant, and a simulated wetland system i...
