| 我国畜禽养殖的规模化程度不断提高，养殖总量不断增加，由此带来的养殖污染问题也日益凸显，
规模化养殖场产生的大量粪便和污水带来的环境压力越来越大，其中尤以重金属污染较为严重。饲养环境污染
及生产过程中添加含有重金属的饲料添加剂是造成畜禽粪便重金属超标的主要原因。由于重金属难以迁移和降
解且容易富集，对土壤生态环境造成极大影响。而且金属元素可随食物链进入人体危害健康，因此加强治理畜
禽粪污重金属污染势在必行。通过阐述畜禽粪污重金属污染的现状、危害及现今可使用的治理方案，找出存在
的问题，提出有效的措施，能更好做到预防与治理相结合，为今后粪污重金属污染的治理提供参考。 |
| 英文摘要: |
| In China, with the increasing scale of livestock and poultry breeding and the increasing total amount of
livestock breeding, the pollution problem of livestock breeding has become increasingly prominent. The environmental
pressure caused by the large amount of feces and sewage from large-scale livestock farms has become more serious,
especially the problem of heavy metal pollution. Feeding environment pollution and feeding additives containing heavy
metals in the production process are the main causes for the excess of heavy metals in livestock and poultry feces. Heavy
metals are difficult to migrate and degrade and are easy to accumulate, which have a great impact on the soil ecological
environment. Moreover, metal elements can enter the human body with the food chain and endanger human health. Therefore,
it is imperative to strengthen the treatment of heavy metal pollution in livestock and poultry waste. In this paper, the current
situation, hazards and available treatment proposals of heavy metal pollution in livestock and poultry waste were introduced,
and effective measurements were put forward to better achieve the goal of combination of prevention and control, which
provide reference for future treatment of heavy metals in waste. |
