Abstract

Cattle slurry storage is a considerable source of pollutant emissions due to microbial degradation of its components and subsequent volatilization. These emissions are directly linked to losses of essential nutrients, which are consequently no longer available for further use (e.g., in biogas plants or for fertilization). Here, we present the correlation between the application of calcium cyanamide (CaCN2) as an additive for efficient mitigation of emissions from cattle slurry storage and the conservation of nutrients. Three series of laboratory storage experiments were conducted using fresh cattle slurry with and without CaCN2 under semiaerobic conditions at ambient temperature for 4 months each. Emission measurements and detailed mass balances, based on slurry analyses and weighing, revealed a considerable reduction in greenhouse gas emissions by 76.3% and concomitant preservation of fresh matter (34.9%), carbon (47.2%), and nitrogen (96.3%) upon facile additive application. Thus, CaCN2 can enhance the value of cattle slurry despite prolonged storage.

通过减少氰氨化钙在贮存过程中的排放来保存牛粪浆中的营养成分
由于牛粪成分的微生物降解和随后的挥发,牛粪储存是一个相当大的污染物排放源。这些排放与基本养分的损失直接相关,这些养分因此无法继续使用(例如,用于沼气厂或施肥)。在此,我们介绍了氰氨化钙(CaCN2)作为添加剂用于有效减少牛粪浆储存过程中的排放与养分保存之间的相关性。在环境温度下的半氧条件下,使用含有或不含 CaCN2 的新鲜牛粪浆进行了三个系列的实验室贮存实验,每个实验持续 4 个月。根据泥浆分析和称重进行的排放测量和详细的质量平衡表明,添加 CaCN2 后,温室气体排放量大大减少了 76.3%,同时新鲜物质(34.9%)、碳(47.2%)和氮(96.3%)也得到了保存。因此,CaCN2 可以提高牛粪浆的价值,尽管需要长时间储存。
