摘要
养殖业废弃物畜禽粪便已成为环境的重要污染源。畜禽粪便会对环境造成恶臭气体污染、有害病源生物污染、药物和添加剂污染、金属元素污染、氮磷污染。同时畜禽粪便中含有大量有机质和作物所需营养元素,又是重要的肥料资源。通过对畜禽粪便生物发酵腐解,可以进行无害化处理。养殖业废弃物的生物腐解进程受C/N比、温度、湿度、O2含量、pH等因素影响。利用腐解后的畜禽粪便制作有机肥料,可以减轻养殖业污染,改善生态环境,促进农业可持续发展。
The faeces from domestic animal has caused serious environmental contamination. It can cause environment problems such as malodorous gas pollution, harmful pathogenic microorganism pollution, antibiotic pollution, metal pollution, N and P pollution. Since there are large amount organic matter and many nutrient elements in the faeces from domestic animal, it also is a major resource of manure. The faeces from domestic animal can be harmless by microorganism′s decomposing. The Process of decomposing are affected by the factors of C/N, temperature, humidity, O_2 and pH. By the way of making fertilizer from decomposed faeces we can decrease the pollution, improve environment and promote the sustainable development of agriculture.
