Understanding the Biotransformation Processes in a Sewer System to Achieve Optimal Management

下水道腐蚀和气味排放给污水管理当局带来了巨大的成本。这些问题主要是由下水道生物转化过程中产生的硫化氢引起的。通过综合实验室控制实验、广泛的实地测量/实验和先进的计算机模拟，该计划旨在对下水道内的生物转化过程，特别是发生在下水道生物膜和沉积物中的过程，有一个基本的了解，并为污水处理当局提供科学和工程支持，以更经济有效的方式管理下水道。重点放在综合下水道和废水处理性能，以实现整体优化的废水管理。

Sewer corrosion and odour emissions are incurring massive costs to the wastewater management authorities. These problems are primarily caused by the hydrogen sulfide produced by the in-sewer biotransformation processes. Through integrating controlled laboratory experiments, extensive field measurement/experiments and advanced computer modelling, the project aims to generate a fundamental understanding of the in-sewer biotransformation processes, in particular those occurring in sewer biofilms and sediments, and to provide scientific and engineering support to the wastewater authorities to manage their sewers in a more cost-effective way. Emphasis is placed on the integrated sewer and wastewater treatment performance to achieve overall optimal wastewater management.
