中文摘要:
      规模化畜禽养殖业为社会带来巨大经济效益的同时,也带来了一系列的环境污染问题。利用畜禽粪 便制备生物炭既可以实现粪便减量化和无害化的目标,减少环境污染,又可以达到废物利用的目的,带来环境和 经济效益。畜禽粪便生物炭因其独特的物理化学性质、低成本和环境友好等优点,被广泛应用于环境修复领域, 用于吸附/固定水体和土壤中的污染物。综述了畜禽粪便生物炭热解温度及酸改性、碱改性、氧化剂改性和金属 氧化物改性等改性方法对其物理化学性质的影响;深入研究畜禽粪便生物炭中重金属化学形态及其浸出行为,并 采用多种污染技术评价方法评估畜禽粪便生物炭的环境风险;最后重点综述了畜禽粪便生物炭对废水中重金属、 有机污染物、抗生素和氮磷等污染物及对土壤中重金属和有机污染物的去除效果及去除机制。畜禽粪便生物炭的 物理化学性质取决于其制备工艺,并且其吸附性能在很大程度上取决于畜禽粪便生物炭自身的物理化学性质。畜 禽粪便生物炭在环境修复中具有广阔的应用前景,但也存在一些问题和挑战需要解决。
英文摘要:
      Although the large-scale livestock and poultry breeding has brought magnificent economic benefits for the society, it also caused a series of environmental pollution problems. The preparation of biochar from livestock manure can not only achieve the goal of manure reduction and harmlessness, reduce environmental pollution, but also attain the purpose of waste utilization and bring environmental and economic benefits. Manure-based biochar is widely used in the field of environmental remediation due to its unique physicochemical properties, low cost and environmental friendliness, which can be used to adsorb/immobilize pollutants in water and soil. The study summarizes the effects of pyrolysis temperature and modification conditions(acid, alkali, oxidant and metal oxide modification)on the physicochemical properties of manure-based biochar. The chemical forms and leaching behavior of heavy metals in manure-based biochar were deeply studied, and a variety of pollution technology evaluation methods were used to evaluate the environmental risks of manure-based biochar. Finally, the study focused on the removal effect and mechanism of manure-based biochar on heavy metals, organic pollutants, antibiotics, nitrogen and phosphorus in wastewater as well as heavy metals and organic pollutants in Soil. The physicochemical properties of manure-based biochar depend on its preparation process, and its adsorption performance largely depends on its physicochemical properties. Manure-based biochar has a broad application prospect in environmental remediation, but there are still some problems and challenges to be solved.
