Porous adsorption plate with multiple functions for petroleum hydrocarbon polluted water bodies and preparation method thereof

Abstract

The invention discloses a porous adsorption plate with multiple functions on petroleum hydrocarbon polluted water bodies and a preparation method thereof. The preparation method comprises the following steps: preparing a NH4HCO3 solution, a NH4H2PO4 solution, a Ca(NO3)2 solution, a NH4OH solution, a hydrochloric acid solution, a NH4Cl water solution and a calcium potassium ethylenediamine tetraacetate solution into a mixed solution F; preparing urea and formalin into a mixed solution L; preparing a poly-beta-hydroxy-butyrate chloroformic solution and a polyethyleneglycol chloroformic solution into a mixed solution M; dropwisely adding the mixed solution L into the mixed solution M to obtain a mixed solution N; dropwisely adding the mixed solution F into the mixed solution N to obtain a mixed solution O; injecting distilled water into a container filled with liquid nitrogen to prepare ice granules, screening, and compacting in a mold; and casting the mixed solution O into the mold to perform freeze molding, demolding and refrigerating to obtain the porous adsorption plate with multiple functions on petroleum hydrocarbon polluted water bodies. The manufacturing technique is simple; and the prepared adsorption plate has high treatment efficiency for petroleum hydrocarbon pollutants, and can not bring about secondary pollution and damage onto the ecological environment of the water bodies.

Description

technical field [0001] The invention belongs to the technical field of treating water bodies polluted by petroleum hydrocarbons, and in particular relates to a porous adsorption plate with multiple functions for water bodies polluted by petroleum hydrocarbons 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 face. [000...
