Enhancing Anaerobic Co-Digestion Performance of Mixed Feed stock Waste through Ammonia Removal********

厌氧消化（AD）是一种成熟的技术，可将生物质转化为能源，并减少有机废物（如城市固体废物的有机部分，污水污泥或乳制品废物）对环境的影响。然而，由于高氨浓度，AD工艺容易受到毒性的影响。氨是有机质中蛋白质含量AD过程中产生的副产物，据报道氨是AD过程中微生物活性的主要抑制剂。文献中报告了氨 ** 毒性的广泛和不同影响。此外，关于从混合原料的共消化工艺的重金属状态中去除氨的信息非常有限。**CHFour Biogas是一家加拿大公司，也是AD领域的行业领导者。CHFour Biogas专门为北美和南美的农业，工业和市政部门提供厌氧消化系统的设计，安装和优化，提供全面的服务，包括可行性研究 ** 和分析，沼气系统设计和规范，咨询和施工管理，原料评估和系统建模，许可，批准和法规。CH Four Biogas有兴趣通过去除氨来提高混合原料有机物（包括牲畜粪便，可消化的制造废物，消费前和消费后的食品废物）的厌氧共消化（A-CoD）性能的可行性研究。** 本研究将根据全因子实验设计进行一系列实验室生物甲烷潜力（BMP）实验，以评估不同方法去除氨的可行性及其对混合有机原料废物A-CoD沼气生产的影响。研究结果将对AD工艺的设计和操作提供新的认识。

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.
