“…Under the conditions of intermolecular hydrogen bonds and direct electrostatic attraction, COD in CWs added with biochar has a good removal effect [22]. At the same time, due to the action of π-π, both greenhouse gases and total nitrogen have a good removal effect [23]. Strong intermolecular π bonds, hydrogen bonds, and electrostatic attraction have been proven to be the main reasons for the high adsorption of pollutants by biochar [12].…”

Constructed wetlands (CWs) is a kind of green environmental protection technology, which is widely used in sewage treatment. The traditional CWs is faced with the problem of low treatment effect of high concentration sewage. In recent years, biochar, as a new type of adsorption material, has been used in CWs because of its advantages of large specific surface area, strong adsorption capacity and wide material sources. This paper systematically summarized the characteristics of biochar and the preparation of biochar by studying the changes of microorganisms added to CWs, and compared the effects of different treatment methods coupled with biochar on the treatment performance of CWs, the effects of biochar coupled with CWs on enzyme activity, functional genes, metabolites and microbial communities were investigated. This review summarizes how different preparation methods affect the properties of biochar and how these biochar cause changes in the microorganisms added to CWs.

“…Constructed wetland is AMD management consisting of media, plants, and microorganisms that mimic natural wetlands to drain and process AMD so that it meets environmental quality standards before being released into public waters (Flores et al, 2019). The use of constructed wetland reduces 89%, 91%, and 91% of Pb, Cr, and Cd, respectively, in AMD through sorption mechanism (Mohammed and Babatunde, 2017), and the addition of zeolite and biochar to the constructed wetlands is able for removal of As (3584%) and Zn (824%) (Guo et al, 2020). The high ability of constructed wetlands to reduce heavy metal contents in AMD was also shown by Singh and Chakraborty (2020), who used cow manure and bamboo chips as organic substrates on constructed wetland and reported high efficiency of metal removal (99.7% Cr, 97.8 Ni, 93.7% Co, 91.6% Fe, and 59.7% Al).…”

Mining activity may potentially produce acid mine drainage (AMD), which has relatively high acidity and dissolved heavy metal concentrations. Constructed wetlands is one of the AMD management methods in which organic matter (OM) plays a very important function in reducing the concentration of heavy metals in AMD through absorption and precipitation processes. Three types of OM (empty fruit bunches of oil palm, chicken manure and water hyacinth) and five levels of OM (0, 10, 20, 30 and 40 Mg ha-1) were applied to reclaimed-mining soils (RMS) in an incubation study. A batch experiment was then performed to measure the effect of OM application on the maximum sorption capacity (Qmax) of iron (Fe) from the AMD onto the mixed soil-OM. The application of OM resulted in increases in soil pH, carboxylic groups, and total functional groups, in which these increases varied based on the types and amounts of OM application. This study also revealed that OM application resulted in increasing Fe sorption. The application of OM increased Qmax values from 2077 to 2348-3259 mg kg-1 (water hyacinth), to 2607-3635 mg kg-1 (chicken manure), and to 2219-2992 mg kg-1 (empty fruit bunches of oil palm). Increasing these Qmax values may ascribe to increasing functional groups of the RMS with OM application. The results prove the importance of OM in controlling the sorption of Fe from AMD onto soils.
