| 摘 要： | 污泥是生物法处理市政污水、工业废水产生的副产物,产量大,且处理不当会造成生态污染。用污泥制备污泥生物炭,既能实现污泥资源化利用又能减少环境污染。对目前热解污泥生物炭制备和施用过程中产生的环境效应进行综述,着重讨论了热解污泥制备污泥生物炭过程中的元素(碳、氢、氧、氮、硫等)转化、污泥生物炭中重金属形态、吸附性质及土壤施用情况。系统地分析污泥生物炭从制备到施用过程的环境效应,有利于对其实际应用进行全面的环境风险评估。

| Abstract: | Sludge is by-product of biological process in the treatment of municipal sewage and industrial wastewater.It has a huge production and may cause ecological pollution if improperly treated.Preparation of biochar with sludge may realize both resource utilization and pollution reduction of the sludge.The environmental effects in the sludge biochar preparation and application process were reviewed.The transformation of elements(carbon,hydrogen,oxygen,nitrogen,sulfur,etc.)and heavy metal species,adsorption property and applied conditions of sludge biochar were discussed.The systematical analysis of the environmental effect of pyrolysis sludge biochar from preparation to application was helpful to its comprehensive environmental risk evaluation. |
