摘　　要：牛粪生物炭具有高比表面积、孔隙度和极性/非极性表面位点等特性,其独特的物理化学性质、低成本和环境友好等优点,有利于吸附/固定水体和土壤中的污染物,固持堆肥养分并减少有害气体的排放,促进有利微生物群落生长,因此被广泛应用于环境修复和农业生产等领域。牛粪生物炭的制备工艺以及改性方法决定其物理化学性质,进而影响牛粪生物炭再废水处理、土壤修复及改善、有机堆肥中的应用。目前,牛粪生物炭对土壤重金属污染、有机污染的修复研究已取得显著效果,牛粪生物炭在土壤改良、废水污染治理方面具有良好的应用前景,但也存在一些问题和挑战需要解决。Cow dung biochar exhibits characteristics such as high specific surface area,porosity,and surface sites ranging from polar to non-polar.These distinctive physicochemical attributes,low cost,and environmental friendliness make it advantageous for adsorbing/fixing pollutants in water bodies and soil,retaining compost nutrients,reducing noxious gas emissions,and fostering the growth of beneficial microbial communities.Therefore,its widespread integration spans environmental remediation and agricultural practices.The preparation process and modification methods of cow dung biochar determine its physicochemical properties,which in turn affect its application in wastewater treatment,soil restoration and improvement,and organic composting.Currently,research on the remediation of soil heavy metal pollution and organic pollution with cow dung biochar has achieved significant results,indicating promising prospects for its application in soil amelioration and wastewater treatment.However,pertinent challenges and obstacles necessitate careful consideration and resolution moving forward.
