Adsorption plate with high-efficient adsorption and enhanced biodegradation of petroleum hydrocarbon pollutants and preparation method thereof

Abstract

The invention discloses an adsorption plate with high-efficient adsorption and enhanced biodegradation of petroleum hydrocarbon pollutants and a preparation method thereof. The preparation method comprises the steps of preparing a mixed solution F from NH4HCO3, Ca(NO3)2, (NH4)2HPO4, a urea water solution and an ethylenediaminetetraacetic acid calcium sodium solution; preparing a mixed solution L from urea and a formaldehyde water solution; preparing a mixed solution M from a poly beta-hydroxybutyrate chloroform solution and a polyethylene glycol chloroform solution; dropping the mixed solution L into the mixed solution M to obtain a mixed solution N; dropping the mixed solution F into the mixed solution N to obtain a mixed solution O; spraying distilled water into a container containing liquid nitrogen to prepare ice ball particles, screening and then placing in a mold for compaction; pouring the mixed solution O into the mold for freezing and shaping, then demolding, and freezing to obtain the adsorption plate; culturing the adsorption plate in a petroleum hydrocarbon degrading bacterial culture solution for 24h and then taking out for air-drying. The preparation process disclosed by the invention is simple, and the prepared adsorption plate has high treatment efficiency against petroleum hydrocarbon pollutants and can prevent secondary pollution and destruction to an ecological environment of a water body.

Description

technical field [0001] The invention belongs to the technical field of treating water bodies polluted by petroleum hydrocarbons, and in particular relates to an adsorption plate for highly efficient adsorption and enhanced biodegradation of petroleum hydrocarbon pollutants and a preparation method thereof. Background technique [0002] In recent years, with the increasing demand for oil and its products in various countries around the world, oil spill accidents have occurred frequently in the process of offshore mining, loading and unloading, transportation and utilization of oil, which not only caused a large amount of crude oil loss, but also caused serious pollution to the environment. It is increasingly threatening the ecological environment of water bodies and land areas, and has long-term harm to water body environment, natural resources and aquaculture resources. Therefore, oil spill pollution in water bodies has become a major environmental problem that people must fa...
