“…In poor phosphoric sludge, REEs are in the form of various oxides: lanthanum oxide La2O3 -0.008%, praseodymium oxide Pr2O3 -0.001%, neodymium oxide Nd2O3 -0.008%, samarium oxide Sm2O3 -0.001%, gadolinium oxide Gd2O3, dysprosium oxide -0.0005% Dy2O3 -0.002%, yttrium oxide Y2O3 -0.22%, ytterbium oxide Yb2O3 -0.001%. The total content of gallium Ga, germanium Gr, and scandium Sn compounds in the milk is up to 0.1% [Tleukeyeva A., 2021].…”

“…Although the efficiency of phosphite oxidation by individual strains of microbes, including soil microbes, has already been, only one study has clarified the ability of microflora to oxidize phosphite in various types of soils. In this regard, it becomes necessary to convert numerous polluting waste into useful resources by means of chemical and biological methods, as well as to introduce waste-free technologies that do not violate the ecological situation [Issayeva, 2021]. The purpose of this study is the possibility of using waste products from the production of phosphorus fertilizers for the cultivation of the Chlorella vulgaris ASLI-1 algae strain, which is promising for use as biofertilizer in agriculture.…”

The possibility of using phosphorus-containing wastewater as a raw material for the cultivation of the green algae strain Chlorella vulgaris ASLI-1 can represent an effective processing of phosphorus-containing by-products. A laboratory experiment was made to study the effect of the concentration of phosphorus-containing wastewater on the biomass density of the green alga strain Chlorella vulgaris ASLI-1. Three weeks after sowing, we measured the biomass density of algae in various components of the phosphorus-containing wastewater. Compared to the control (distilled water), the addition of phosphorus-containing wastes did not adversely affect the culture of green algae, with the exception of a 20% medium where algal cells were discolored and had a low biomass density, 104 CFU. However, more research is needed to better study the response of green algae to phosphorus-containing waste, to determine the amount of phosphorus in cells and solution. In addition, evaluate the agronomic efficiency of the Chlorella vulgaris ASLI-1 strain, cultivated on phosphorus-containing waste, when applying fertilizers for growing vegetables.

“…They provide habitat for plankton and other animals and reduce the movement of sediments through a synergistic action between their roots and other microorganisms [22]. Current studies focus more on the removal efficiency of certain aquatic plants for different nutrients in water [23][24][25]. For example, for removing nitrogen in the water, wetland plants can directly absorb the inorganic nitrogen and transform it into organic nitrogen.…”

Constructed wetland parks in urban areas can offer potential for an integration of water conservation and purification. Compared with other treatments, filtering out pollutants by wetland plants is one of the methods used widely for its fast processing time and limited costs. And species allocation plays an important role in the purification process. However, some problems are still waiting for further discussions, such as the purification efficiency in winter due to plant growth rate, etc. Against this background, this paper introduced the Tianhe Wetland Park in China as the site for a comparative experiment, to propose a methodology testing the purification effect under different plant communities. Through site investigation and lab experiment with water monitoring, the process of water purification by wetland was simulated in the park. After a period of observation and measurement, seven water indexes (pH value, dissolved oxygen, total phosphorus, total nitrogen, ammonia nitrogen, chemical oxygen demand, and turbidity) were selected for the evaluation of water quality to compare the different absorption efficiency by different communities. As a result, the research showed that a configuration of plant community using arboreal, emergent, and submerged plants can carry out a good purification effect during the winter, including Callistemon viminalis, Bischofia javanica, Canna indica, Juncus effusus, Vallisneria natans, and Hydrilla verticillata var. rosburghii. The removal rate of DO, TU, COD, TP and TN by the designed community can reach to 43%, 65%, 45%, 51% and 62% in sampling sites. Finally, based on the research results, further suggestions for the development of wetlands were proposed to improve the park management in the study area.
