Abstract

Renewable energy can boost the growing population’s need and rapid budgetary development. To reduce fossil fuel consumption is the initial purpose of renewable and sustainable energy, producing valuable bio-based products. The fermenters, using for pretreatment of swine manure, and involvement of swine carcasses are reported to enhance organic loading rate followed by improved biogas yield on household digesters. The compositions such as animal residues, pathogenic microbes, pharmaceutical residues and nutrient compositions including undigested feed are still confused. Therefore, it is mandatory to optimize and stabilize anaerobic practice and digestate filtration purification for consequential fertilizer consumption. The effective bio-methane recovery from energy-rich compounds is challenging due to slow degradation procedures. The pretreatment procedure could enhance lipid depolymerization and improve anaerobic fermentation. This article deeply focuses on biodegradation of swine manure. The components of this manure were evaluated and established several approaches to improve biogas production. Furthermore, recycling of co-digestates was discussed in detail as fertilizer consumption including hygienic aspects of manure and pretreatment strategies of biomass residues.

Key points

• Co-digestion of manure and carcasses enhance bio-methane production.

• Removel of ammonia from biogas digester may improve bio-methane gas.

• A strong antimicrobial influence has been reported on biogas production.

猪粪在营养和能量生产中的增值

摘要

可再生能源可以促进不断增长的人口需求和快速的预算发展。减少化石燃料的消耗是可再生和可持续能源的最初目的，生产有价值的生物基产品。据报道，用于猪粪预处理的发酵罐和猪car体的参与提高了有机负荷率，随后提高了家用沼气池的沼气产量。诸如动​​物残留物，病原微生物，药物残留物和包括未消化饲料的营养成分之类的组合物仍然令人困惑。因此，必须优化和稳定厌氧操作并消化过滤提纯以节省肥料。由于降解过程缓慢，从高能化合物中有效回收生物甲烷具有挑战性。预处理程序可以增强脂质解聚并改善厌氧发酵。本文深入研究了猪粪的生物降解。对该粪便的成分进行了评估，并建立了几种提高沼气产量的方法。此外，详细讨论了共消化物的循环利用，包括肥料消耗，包括粪便的卫生方面和生物质残留物的预处理策略。

关键点

•粪便和car体共同消化可提高生物甲烷的产生量。

•从沼气池中去除氨气可能会改善沼气。

•据报道，对沼气的产生有很强的抗菌作用。
