硫自养反硝化脱氮技术发展现状
Current developments in sulfur-autotrophic denitrification technology
摘要
Abstract
Sulfur-autotrophic denitrification nitrogen removal technology was identified as an efficient and environmentally friendly technology for domestic and industrial wastewater treatment.This technology was operated by using sulfur,sulfides,sodium thiosulfate and other substances as electron donors;under anaerobic conditions,the reduction of nitrates and nitrites was achieved,and harmless nitrogen gas was ultimately generated.It was endowed with multiple advantages such as energy conservation and pollution reduction.Starting from the principle of this technology,the performance characteristics of different sulfur electron donors,reaction kinetic models and functional microorganisms were discussed.Moreover,the influence mechanism of elemental sulfur nitrogen removal materials on the denitrification process was focused on and analyzed.Through a review of current engineering application cases of sulfur-autotrophic denitrification,the development status of this technology in three directions advanced treatment of industrial wastewater,water body remediation,and coupled application with other technologies was explored in depth.Thus,the broad application prospects of sulfur-autotrophic denitrification technology were fully demonstrated.Although remarkable progress was made in this technology across multiple fields,its large-scale application was still confronted with numerous challenges.These challenges included the stable supply of sulfur sources,the optimization of reaction conditions,and the precise regulation of microbial communities in high-salinity or complex wastewater environments,all of which were required to be further researched and analyzed.关键词
