TL;DR: Results showed that biochar application did not change NH3 volatilization fluxes pattern after N fertilization, and higher NH4+-N and lower NO3--N concentrations of surface soil underBiochar application were observed compared with control at tillering stage, whereas they were at similar level at jointing stage.

TL;DR: The PSB/Fe3O4/biochar composites are found as a very promising material for bioremediation in the wastewater treatment and their nutrient removal capability remained effective even after five cycles.

TL;DR: A floating bed system vegetated with Oenanthe javanica was adopted in this study to treat two types of low-pollution wastewater (LPW): polluted river water and treated domestic wastewater, and the results provide engineering parameters for the future design of an ecological remediation technology for LPW purification.

TL;DR: In this paper, a metal element improved biochar-based nitrate radical adsorbent and a preparation method thereof was disclosed, which can be used for effectively removing the nitrate nitrogen in a water body; besides, the effects of fixing carbon, reducing discharge and relieving the non-point source pollution are achieved.

TL;DR: In this article, an improved charcoal-based phosphorous removal adsorbent and a preparation method of the improved charcoal based adsorbents are presented, which includes the following steps: loading light rare earth elements to charcoal under optimized conditions, and preparing a high-efficiency environment-friendly charcoal based PHOSA, impregnating cleaned and dried plant powder by using a cerium chloride solution with a certain concentration, and regulating a mass ratio of the original material of charcoal to Ce element to be 5-15 percent.
