In order to meet the needs of ecological buildings, it is necessary to improve the speed of sewage treatment. Therefore, this study analyzed the impact of zinc oxide nanoparticles on the water supply and drainage of ecological buildings. In the experiment, zinc oxide nanoparticles were selected and the experimental environment was set up to study the treatment effect of nano particles on water supply and drainage wastewater. The experimental results show that: the application of ZnO nanoparticles in water supply and drainage can effectively remove trace elements in sewage and reduce the eutrophication of groundwater; zinc oxide nanoparticles can change the morphology of mold group in sewage and inhibit the growth of sewage. The application of ZnO nanoparticles in the water supply and drainage of ecological buildings can effectively improve the water purification rate and improve the recycling efficiency of water resources.

Background: Nanoparticles are globally synthesized for their antimicrobial, anti-inflammatory, wound healing, catalytic, magnetic, optical, and electronic properties that have put them at the forefront of a wide variety of studies. Among them, zinc oxide (ZnO) has received much consideration due to its technological and medicinal applications. In this study, we report on the synthesis process of ZnO nanoparticles using Athrixia phylicoides DC natural extract as a reducing agent.   Methods: Liquid chromatography–mass spectrometry (LC-MS) was used to identify the compounds responsible for the synthesis of ZnO nanoparticles. Structural, morphological and optical properties of the synthesized nanoparticles have been characterized through X-ray diffraction (XRD), Ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS).   Results: LC-MS results showed that different flavonoids and polyphenols, as well as Coumarin, an aromatic compound, reacted with the precursor to form ZnO nanoparticles. XRD and UV-Vis analysis confirmed the synthesis of ZnO nanoparticles, with a spherical shape showed in SEM images. The quasi-spherical ZnO crystals had an average crystallite size of 24 nm. EDS and FTIR analysis confirmed that the powders were pure with no other phase or impurity.   Conclusions: This study successfully demonstrated that the natural plant extract of A. phylicoides DC. can be used in the bio-reduction of zinc nitrate hexahydrate to prepare pure ZnO nanoparticles, thus, extending the use of this plant to an industrial level.
