| 澳大利亚昆士兰大学袁志国教授学术讲座 题目：Exploring new opportunities for resource reuse in wastewater management 时间：2018年5月25日下午15:30 地点： 环境馆东三楼会议室 主持： 曾光明 院长教授、王冬波 副教授 欢迎有兴趣的老师、研究生、本科生参加。 ------------------- 学术讲座摘要： There is currently an on-going paradigm shift in wastewater management from pollutants removal to resource recovery. The primary resources in wastewater are water, energy and nutrients. The current research efforts focus on the recovery of these resources. The recovered products need to achieve a commodity quality to be competitive in the market, which typically add significantly to the capital and operational costs. An additional/alternative option is to reuse various types of substances in wastewater for beneficial purposes. Such reuse options do not require the recovery of commodity-quality products, yet bringing about significant/substantial economic/environmental benefits as these substances could potentially replace the more costly commodity chemicals that would other be required. A well-known example is the use of organic carbon in wastewater to support nitrogen and phosphorus removal through the incorporation of anoxic and anaerobic zones in a treatment process. This is already a common practice in contemporary wastewater treatment plants. In this presentation, it will be demonstrated that a wide range of opportunities can be created through a whole-of-system approach to wastewater management. Three recent examples will be discussed: 1. Multiple use of iron salts in wastewater management. Recent research has demonstrated that iron salts addition to sewers for sewer sulfide control can enhance phosphorus removal in the aerobic wastewater treatment reactor, and also control hydrogen sulfide in the anaerobic sludge digester. These results call for an integrated consideration of sewers and wastewater treatment plants beyond their hydraulic connections. 2. The use of anaerobic sludge digestion liquor to control the growth of nitrite oxidizing bacteria (NOB) in the mainstream treatment. Anaerobic sludge digestion liquor contains an elevated concentration of ammonium nitrogen (~1gN/L), which could be used to suppress the mainstream NOB growth through innovative process design, leading to the nitrite shunt or partial nitritation in the mainstream treatment. 3. The use of biogas as a supplementary carbon source to enhance nitrate/nitrite removal through the use of a membrane biofilm reactor, thus eliminating the need for imported carbon sources that are often required for enhanced nitrogen removal performance. 袁志国教授个人简历： Prof Zhiguo Yuan is the Director of the Advanced Water Management Centre at The University of Queensland, and a Fellow of the Australian Academy of Technological Sciences and Engineering (ATSE) and an IWA Fellow. His research focuses on development of innovative solutions for urban water management through effective integration of fundamental science and applied engineering. He has to date published over 350 fully refereed journal papers including a paper in Nature (2013) and Science (2014), which has to date attracted over 18,000 citations, giving an h-index of 74 (May 2018, Google Scholar). He is the founder of three biotechnology businesses namely SeweX, Cloevis and Lodomat. His research achievements and leadership have been recognized through national and international awards including the 2015 ATSE Clunies Ross Award. He was named as one of Engineers Australia’s Top 100 Most Influential Engineers for 2015. He was awarded the highly prestigious ARC Australian Laureate Fellowship in 2017. He is an Editor for Water Research.  网页：http://www.awmc.uq.edu.au/zhiguo-yuan Email：z.yuan@awmc.uq.edu.au |
