TL;DR: In this paper, a bioreactor (stirred tank reactor) especially constructed for this purpose was used to extract zinc from zinc oxide contained in filter dust, and leaching activity occurs in a pH range from 2 to 7.
Abstract: Filter dusts from metal-processing industries contain valuable metals which should be recycled. Some disadvantages of conventional recycling methods can be avoided by applying biohydrometallurgical methods. Fungi are suitable for such processes because they are fairly resistant to heavy metals. Furthermore, leaching activity occurs in a pH range from 2 to 7. This is important because filter dusts generally raise the pH of the medium. Leaching of zinc from zinc oxide contained in filter dust was possible in a bioreactor (stirred tank reactor) especially constructed for this purpose

TL;DR: It is concluded that plant carbon source addition for all types of CWs and bioreactors can improve the nitrate removal efficiency to some extent, and the dosing method of plant carbon sources for denitrification should be further studied and optimized in the future.
Abstract: Water quality standard for nitrate becomes more and more strict, and the plant carbon source is widely used for denitrification by constructed wetland (CW) and bioreactor. However, the nitrate removal efficiency by different types of plant carbon source are not evaluated comprehensively. Denitrification performance of different plant carbon sources, and the influence of dosing method and pretreatment are thoroughly reviewed in this paper, which aims to investigate the accurate utilization of plant carbon source for nitrogen (as nitrate) removal. It is concluded that plant carbon source addition for all types of CWs and bioreactors can improve the nitrate removal efficiency to some extent, and the dosing method of plant carbon source for denitrification should be further studied and optimized in the future. The popular carbon sources for CW and bioreactor denitrification enhancement are woodchip, chopped macrophytes, crop plants, macrophytes litters, etc. The recommended optimum C:N ratios for CW and bioreactor are 4.0:5.0 and 1.8:3.0, respectively. The physical and biological pretreatments are selected to supply organic carbon for long-term denitrification.
