    摘要: The present invention provides a method for constructing a halophilic nitrogen assimilation microbiome, and belongs to the technical fields of microorganisms as well as environmental governance and restoration. According to the present invention, a strain of Psychrobacter aquimaris A4N01 is screened from marine sediments; the strain can assimilate ammonia nitrogen to synthesize organic nitrogen, and simultaneously convert organic matters and phosphorus. A halophilic nitrogen assimilation microbiome developed by the strain has good nutrient conversion removal capacity and settling performance, has wide tolerance to salinity, and can be used in high-salinity wastewater treatment, saline-alkali soil fertilization, etc., so as to realize recycling of nutrient elements such as nitrogen and phosphorus in high-salinity environments. The method is simple in operation and low in costs and is environmentally friendly, therefore having good practical application value.

    摘要: Provided is a micro-polluted water body ecological treatment method based on aquatic forest system construction. The method comprises the following steps: (1) investigating a pollution source of a micro-polluted water body; (2) estimating an annual pollution load of the micro-polluted water body which needs to be reduced; (3) designing aquatic animals and plants; and (4) constructing the aquatic animals and plants. By using a water body treated by means of the method in the present invention, an aquatic forest can be formed, and the synergistic effect, nutritional relationship, food chain relationship, etc., between organisms can be fully utilized for effective operation, such that not only can the combined benefits of water quality purification and water body resource utilization be achieved, but the organic unity of environmental protection, economic development, and the improvement of people's livelihood can also be realized.

    摘要: The present invention relates to the field of environmental pollution remediation technology, in particular to a nanocomposite preparation and a method for making the same and use thereof. The nanocomposite preparation provided herein includes a nanomaterial and an extracellular polymeric substance (EPS) solution of a microorganism, where the nanomaterial is graphene oxide (GO) or multi-walled carbon nanotubes (CNT); and the microorganism is Paracoccus aminovorans HPD-2, deposited in China General Microbiological Culture Collection (CGMCC) Center, with a deposition number of CGMCC No. 2568. The nanomaterial and EPS system in the present disclosure may improve the bioeffectiveness of Polycyclic Aromatic Hydrocarbons (PAHs) in soil and thus the degradation of PAHs compared to a single system. The synergistic effect between the nanomaterial and the EPS of the degrading bacteria significantly improves the removal of PAHs from soil and water, thus greatly reducing the remediation cycle of the PAH-contaminated soil and water.

    摘要: A biological desalination process to remove salt from seawater using naturally grown algae or cyanobacteria in an attached growth photobioreactor setup. The photobioreactor (PBR) structure can be vertical or horizontal in orientation. Any shape of PBR can provide more light contact to the algae or cyanobacteria for enhanced growth on support media. The reactor can be designed in a way that can get maximum exposure to sunlight. The influent seawater is mixed with nutrients that are essential for the growth of algae or cyanobacteria. The main objective is to remove the salt from the brackish, saline, hypersaline or seawater. The influent seawater can be treated using the attached growth of algae or cyanobacteria, and the effluent from the PBR can be further treated based on desired water use.
