Application and Development of Bio-sand Filtration Technology for Processing Drinking Water in Rural Areas
Published 2022-01-01“…It has been a focus for researchers to study how to ensure the safety of drinking water in rural areas.Bio-sand filtration (BSF) technology has advantages including convenient construction,low water production costs,low energy consumption,and stable and reliable operation,and thus it is more suitable for promotion in rural areas than that in cities.Considering the water shortage and drinking water safety issues,this paper introduces the removal effects of BSF on pollutants such as turbidity,organic pollution,nitrogen and phosphorus,bacteria,and metals,and the advantages and disadvantages of BSF are compared.Moreover,the future application prospects of BSF technology are discussed.…”

Spatial heterogeneity of soil factors enhances intraspecific variation in plant functional traits in a desert ecosystem
Published 2024-12-01“…The order of intraspecific trait variation among different life forms was herbs > shrubs > trees in both the soil moisture-salinity habitats. (2) At the community level, intraspecific variation of leaf carbon, nitrogen, plant height and chlorophyll content in high moisture-salinity habitat was higher than that in low moisture-salinity habitat, while the opposite was true for leaf thickness and leaf phosphorus content. (3) Our findings revealed a positive impact of soil heterogeneity on intraspecific traits variation. …”
