Magnetic sludge carbon biological filler with core-at-shell structure and preparation method and application thereof

The invention discloses magnetic sludge carbon biological filler with a core-at-shell structure and preparation method and application thereof. The magnetic sludge carbon biological filler is prepared by using Fe3O4 magnetic microsphere as a magnetic core, iron-containing sludge as an intermediate layer raw material and common sludge or zinc-containing sludge (preferred) as a shell raw material, adopting a repetitive impregnation-drying method to sequentially wrap the intermediate layer raw material and the shell raw material on the Fe3O4 magnetic microsphere to form a precursor of the core-at-shell structure, and then performing pyrolysis and after-treatment. Since the magnetic material is used as the core and the sludge carbon is used as the shell material, the prepared magnetic sludge carbon biological filler with the core-at-shell structure not only can solve the problem that a powder magnetic material is difficult to separate, and can also solve the problem that ferrite used as a magnetic matrix is corroded by microorganisms; the specific surface of the porous sludge carbon in a shell layer is large, a magnetic environment for growth can be provided for more microorganisms, the metabolic efficiency of the microorganisms is improved and the tail water treatment efficiency of domestic sewage plants is greatly improved.

Plant expression vector of arabidopsis glutathione dependent formaldehyde dehydrogenase gene, construction method and application thereof

InactiveCN101570761APromote absorptionImproves tolerance to exogenous formaldehydeVector-based foreign material introductionBiotechnologyNicotiana tabacum
The invention relates to a plant expression vector pH2-35S-PrbcS-adh of arabidopsis glutathione-dependent formaldehyde dehydrogenase gene, which is the plant expression vector of light-induced promoter (PrbcS) containing tomato Rubisco 3C small subunit gene and the arabidopsis glutathione-dependent formaldehyde dehydrogenase (FALDH) gene adh. The gene adh is amplified from arabidopsis, and the over expression of the gene adh in tobacco lamina cytoplasm is controlled by the light-induced promoter, so that the efficiency of decomposing formaldehyde by tobacco cell can be improved, thus enhancing the capability of absorbing and enduring exogenous formaldehyde by plant. The experiment proves that enzyme activity of adh transgenic tobacco FALDH is increased by about 3-5 times compared with that of wild type; after being cultured for 30 days on an MS solid culture medium containing 10mmol/L of formaldehyde, the growing situation of the adh transgenic tobacco is obviously superior to that of wild type. In addition, when 2mM formaldehyde liquid is used for treating the plant, the formaldehyde absorption rate of the adh transgenic tobacco is obviously higher than that of wild type.

Method for promoting formation of anaerobic granular sludge

The invention belongs to the field of wastewater treatment, and particularly relates to a method for promoting formation of anaerobic granular sludge, which comprises the following steps: 1) adding an iron-based material into an anaerobic reactor, and adding sludge; 2) pumping synthetic wastewater into the anaerobic reactor, and starting the anaerobic reactor; and 3) when gas production and water outgoing are stable in the reaction, and the measured volatile suspended matter of the granular sludge accounts for 70-90% of the total suspended matter mass of the sludge, determining that the granular sludge is mature, stopping running of the reactor, and recovering mature granular sludge. The iron-based material added in the invention has a large specific surface area, which is beneficial to enrichment of anaerobic microorganisms on the surface of the iron-based material so as to form a sludge aggregate. The iron-based material is close to mature granular sludge in density and can float up and down in the anaerobic reactor, so that sludge deposition caused by increase of the volume weight of the sludge is avoided. The iron-based material is used as a core, so that the mechanical property of the anaerobic granular sludge is improved.
