项目摘要
In Canada, medium-to-large scale municipal wastewater treatment plants (WWTPs) have been adapting anaerobic (AN) digestion technologies to generate energy in the form of biogas (60-75% methane) from wastewater sludge. Other benefits of AN digestion are diversion of organic waste from landfills, reduction of pathogens and odour, production of organic fertilizer, and reduction of greenhouse emissions. While AN digestion process is effective for reducing pathogens and destroying organic matter, solids reduction above 50% is often difficult to achieve. Therefore, advanced AN digestion processes with pretreatments and different digestion combinations (i.e. stage digestion) have gained interest in recent years. Furthermore, substantial ammonia and phosphate are released in AN digesters through hydrolysis of waste sludge which can degrade the final effluent quality of a WWTP. Therefore, sequential AN/ aerobic (AERO) sludge digestion process has been recommended due to many additional advantages (e.g. higher solids/pathogen destruction, ammonia removal, odour reduction and better dewaterability) over the single-stage AN digestion. Metro Vancouver and UBC Bioreactor Technology Group have recently completed an NSERC ENGAGE project (Phase A) that pointed out significant advantages of the sequential AN/AERO combination over the current AN digester configuration at Annacis. The main objective of this proposal (Phase B) is to verify these beneficial effects in larger-scale automated fermenters with automated air flow control valves for dissolved oxygen (DO) set-point control. If results from Phase B confirm the advantages, Metro Vancouver will have the option to convert some of the existing flow-through AN vessels to AERO/ANOX sludge digesters to operate a combined AN/AERO/ANOX system at Annacis. In addition to conventional digestion performance parameters, Phase B will also evaluate the fate of a group selected pharmaceuticals in digesters. The knowledge gained will lead to other biosolids-to-energy conversion and waste minimization opportunities at WWTPs in BC (e.g. Northwest Langley) and Canada. It will train highly qualified personnel (HQP) in a specialized field.
在加拿大,大中型城市污水处理厂 (WWTP) 一直在采用厌氧 (AN) 消化技术,从废水污泥中产生沼气(60-75% 甲烷)形式的能源。 AN消化的其他好处包括将有机废物从垃圾填埋场转移、减少病原体和气味、生产有机肥料以及减少温室气体排放。虽然 AN 消化过程可有效减少病原体和破坏有机物,但固体含量减少 50% 以上通常很难实现。因此,具有预处理和不同消化组合(即阶段消化)的先进AN消化工艺近年来引起了人们的兴趣。此外,通过废污泥的水解,AN 消化池中会释放出大量的氨和磷酸盐,这会降低污水处理厂的最终出水水质。因此,连续式 AN/好氧 (AERO) 污泥消化工艺与单级 AN 消化相比具有许多其他优点(例如更高的固体/病原体破坏、氨去除、气味减少和更好的脱水性),因此受到推荐。大温哥华地区和 UBC 生物反应器技术集团最近完成了 NSERC ENGAGE 项目(A 期),该项目指出了顺序 AN/AERO 组合相对于 Annacis 当前 AN 消化器配置的显着优势。该提案(B 阶段)的主要目标是验证大型自动化发酵罐的这些有益效果,该发酵罐配有用于溶解氧 (DO) 设定点控制的自动气流控制阀。如果 B 阶段的结果证实了这些优势,大温哥华地区将可以选择将一些现有的流通式 AN 容器转换为 AERO/ANOX 污泥消化器,以便在 Annacis 运行 AN/AERO/ANOX 组合系统。除了常规的消化性能参数外,B 阶段还将评估一组选定的药物在消化器中的命运。所获得的知识将为不列颠哥伦比亚省(例如西北兰利)和加拿大的污水处理厂带来其他生物固体到能源转化和废物最小化的机会。它将培养专门领域的高素质人才(HQP)。
