Article Description

The waste glass was usually recycled in the generation of rock aggregate and concrete. However, the traditional utilization of waste glass hindered its potential application in resource recycling. This work produced the glass pumice via waste glass powder for the first time and evaluated its potential application as filled substrates in vertical subsurface flow constructed wetland. The performance of glass pumice in constructed wetland showed that the maximal removal of TSS, turbidity, COD, NH 4 + -N, TN and TP was 81.99 %, 88.62 %, 71.10 %, 83.64 %, 90.96 % and 58.88 %, respectively. The reduced hydraulic loading along with increased cycling times was in favor of the removal efficient of physical pollutants and nutrients, where the high specific surface area (>2 m 2 /g) of synthetic glass pumice enhanced capability of adsorption. In addition, the satisfying nutrient removal efficient attributed to glass pumice-mediated increased dissolved oxygen transfer rate in the vertical direction. The slow dissolution of exchangeable cations in glass pumice limited the adsorption and precipitation of phosphorus while the TP removal could only range from 16.30 %–58.88 %. The operating efficiency could be increased due to the occurrence of initial clogging while microorganisms subsequently attached to the glass pumice gradually formed biofilms to remove organic matters. The principal component analysis suggested environmental parameters were closely correlated to the operation performance of constructed wetlands. This study evaluated the performance of constructed wetland based on glass pumice and provided novelty insights into the resource recycling of waste glass.
