Enhancing Anaerobic Co Digestion Performance

项目摘要

Anaerobic digestion (AD) is a well established technology to convert biomass to energy and reduce the**environmental impacts of organic wastes such as organic fraction of municipal solid waste, sewage sludge or dairy waste. However, the AD process is susceptible to influence of toxicity due to high ammonia concentrations.**Ammonia is the by-product resulting from the AD of proteins content of organic matter and it has been reported**as a major inhibitor of microbial activities during AD process. A wide range and varying effect for ammonia**toxicity has been reported in the literature. Also, there is very limited information available on removal of ammonia from digestate of Co-Digestion process of mixed feedstock. **CHFour Biogas is a Canadian company and an industry leader in the field of AD. CHFour Biogas specializes in the**design, installation and optimization of anaerobic digestion systems for the agricultural, industrial and municipal**sectors throughout North and South America offering a comprehensive list of services including feasibility study**and analysis, biogas system design & specification, consultations and construction management, feed stock**evaluation & system modeling, permitting, approvals, and regulations. CH Four Biogas is interested in conducting research on the feasibility of enhancing the performance of anaerobic Co-Digestion (A-CoD) of mixed feedstock organics (including livestock manure, digestible manufacturing waste, pre- and post-consumer food wastes) by removal of ammonia. **The research will be carried out by conducting a series of laboratory biomethane potential (BMP) experiments according to a full factorial experimental design to evaluate the feasibility of different methods for removal of ammonia and its effect on biogas production from A-CoD of mixed organic feedstock wastes. Results will advance the existing knowledge on the design and operation of AD process.

厌氧消化（AD）是一项良好的技术，可将生物量转化为能源并减少有机废物的环境影响，例如市政固体废物，污水污泥或乳制品废物等有机浪费。但是，AD过程容易受到高氨浓度引起的毒性的影响。**氨是由有机物蛋白质含量的AD产生的副产物，并且据报道**是AD过程中微生物活性的主要抑制剂。文献中已经报道了对氨**毒性的广泛范围和不同作用。此外，还有非常有限的信息，可从混合原料的共同消化过程中去除氨的信息。 ** Chfour Miogas是加拿大公司，也是广告领域的行业领导者。 Chfour沼气专门针对整个北部和南美的农业，工业和市政**领域的厌氧消化系统设计，安装和优化，提供全面的服务清单，包括可行性研究**和分析，分析和分析，生物群岛系统设计和系统设计，咨询和建筑管理，咨询和建筑管理，饲料管理，供给**评估和系统模型和系统模型，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准，批准。 CH四个沼气有兴趣进行研究，以提高混合原料有机物（包括牲畜肥料，可消化的制造废物，消化前和消费前和消费前食品废物）的厌氧共管剂（A-COD）的可行性。 **根据完整的阶乘实验设计，将通过进行一系列实验室生物甲烷电位（BMP）实验来进行研究，以评估不同方法去除氨的可行性及其对沼气对沼气产生的影响，从而从混合有机原料废物的A-COD中进行了对沼气的影响。结果将推进有关广告过程设计和操作的现有知识。
