Odorous emissions from wastewater biosolids processing can cause nuisance impacts to the surrounding community. Odour Wheels are an effective tool for environmental odour management, but have yet to be provided for wastewater biosolids processing. Emissions throughout the biosolids processing from eight wastewater treatment plants, each with different unit operation configurations, were surveyed to identify odorants present and their olfactory properties. Chemical and olfactory methods identified a range of odorants and odours emitted throughout biosolids processing. Within the biosolids processing locations studied Sulfur type odours, described as rotten eggs or cabbage, were typically encountered. However, there was also a varying presence of Rancid/putrid and Faecal/manure type odours. Odour Wheels were generated to communicate both the olfactory and chemical components of emissions which were measured throughout biosolids processing. Examples based on the operation of the eight wastewater treatment plants were used to demonstrate how the Odour Wheels can be used as an onsite odour management aid. The paper demonstrates how Odour Wheels can be prepared using chemical and olfactory measurements and then used to communicate olfactory properties, as well as identify the causes of nuisance emissions throughout biosolids processing at wastewater treatment plants. The linking of odours and odorants to process conditions throughout biosolids processing facilitates effective abatement and management practices.

废水生物固体处理过程中产生的恶臭排放物可能对周围社区造成有害影响。气味轮是用于环境气味管理的有效工具，但尚未提供用于废水生物固体处理的工具。调查了八个废水处理厂在整个生物固体处理过程中的排放量，每个污水处理厂的单元运行配置均不同，以识别存在的气味及其嗅觉特性。化学和嗅觉方法确定了整个生物固体加工过程中散发出的各种气味和气味。在研究的生物固体加工场所内，通常会遇到被称为腐烂的鸡蛋或卷心菜的硫味。但是，还有臭味/腐烂和粪便/粪便类型的气味。产生了气味轮，以传达排放物的嗅觉和化学成分，这些排放物是在整个生物固体加工过程中测量的。以八个废水处理厂的运行为例，说明了气味轮如何用作现场气味管理辅助剂。本文演示了如何使用化学和嗅觉测量方法来制备气味轮，然后将其用于传递嗅觉特性，并确定废水处理厂整个生物固体处理过程中产生有害排放的原因。在整个生物固体加工过程中，将气味和增味剂与加工条件联系起来，可促进有效的减排和管理实践。以八个污水处理厂的运行为基础的示例被用来说明气味轮如何用作现场气味管理辅助剂。本文演示了如何使用化学和嗅觉测量方法来制备气味轮，然后将其用于传递嗅觉特性，并确定废水处理厂整个生物固体处理过程中产生有害排放的原因。在整个生物固体加工过程中，将气味和增味剂与加工条件联系起来，可促进有效的减排和管理实践。以八个污水处理厂的运行为基础的示例被用来说明气味轮如何用作现场气味管理辅助剂。本文演示了如何使用化学和嗅觉测量方法来制备气味轮，然后将其用于传递嗅觉特性，并确定废水处理厂整个生物固体处理过程中产生有害排放的原因。在整个生物固体加工过程中，将气味和增味剂与加工条件联系起来，可促进有效的减排和管理实践。并确定废水处理厂整个生物固体处理过程中产生有害排放的原因。在整个生物固体加工过程中，将气味和增味剂与加工条件联系起来，可促进有效的减排和管理实践。并确定废水处理厂整个生物固体处理过程中产生有害排放的原因。在整个生物固体加工过程中，将气味和增味剂与加工条件联系起来，可促进有效的减排和管理实践。
