摘要

对动物蛋白日益增长的需求给目前的动物生产系统带来了压力。生产者发现的提高动物生产性能的替代方法之一是使用兽药,特别是抗生素。然而,由于巴西有大约4200万头生猪,它的滥用可能会对生产地的环境平衡造成风险。有了这群猪,养猪业就有可能产生巨大的环境影响。作为大量液体猪粪的替代用途,许多生产者一直在土壤中使用这种浆液作为生物肥料。兽药残留会随环境基质积累并渗入水资源。从这个意义上说,必须投入更多的精力研究兽药污染有机废水的处理技术和工艺。低成本和环境友好的替代处理系统是必要的,以尽量减少这些污染物进入环境。因此,将堆肥过程定义为有机物的好氧微生物分解过程,可以作为处理兽药污染废水的替代方法。本综述旨在提高学术界对兽药残留及其在不同环境基质中的污染潜力的认识,并评估堆肥过程作为一种技术,以尽量减少猪活动废物对环境的影响。

Compostagem de efluente suíno no tratamento de resíduos de fármacos veterinários
The increasing need for animal protein has exerted pressures on the current animal production system. One of the alternatives found by producers to improve animal performance has been the use of veterinary drugs, especially antibiotics. However, its indiscriminate use can be a risk to the environmental balance of the producing locations since Brazil has approximately 42 million pigs. With this herd, pig farming represents a great potential for generating environmental impacts. As an alternative use of the large volume of liquid pig manure generated, many producers have been using this slurry in the soil as a bio fertilizer. Residues of veterinary drugs are capable of accumulation with environmental matrices and leach into water resources. In this sense, it is mandatory to dedicate more efforts on the study of techniques and processes for the treatment of organic effluents contaminated by veterinary drugs. Low-cost and environmentally friendly alternative treatment systems are necessary, in order to minimize the entry of these contaminants into the environment. Therefore, the composting process, defined as aerobic microbial decomposition process of organic matter, can be an alternative for treating the effluents contaminated by veterinary drugs. This review to aims to create awareness in the academic community regarding the veterinary drug residues and their contamination potential in different environmental matrices, as well as evaluating the composting process as a technique to minimize the impacts of the swine activity waste on the environment.
