Over the years, his numerous contributions included developing cutting-edge technologies to improve water quality and reduce pollution. The biological process he designed for removing nitrogen and phosphorus from used water facilities now are applied around the world. In this Q&A, Dr.In recent years, Dr. James Barnard has reflected on and improved the traditional biological nitrogen and phosphorus removal technology of sewage, and has collaborated with colleagues and several research institutions to further develop the promotion and engineering application of sidestream activated sludge fermentation technology in the United States. Barnard shares his insights and reflections on his career, his accomplishments, and the future of water treatment technology. 在水处置范畴被称为“生物去除养分物之父”的詹姆斯·巴纳德博士比来从博科威奇公司退休，此前他是该范畴持久卓异的专家。多年来，他的浩繁进献包罗开辟改良水质和削减污染的尖端手艺。他设想的从污水举措措施中去除氮和磷的生物进程此刻活着界各地获得利用。近年来James Barnard 博士对保守污水生物脱氮除磷手艺进行反思与改良，与同事和一些研究机构合作，进一步成长了活性污泥发酵手艺（S2EBPR)在美国的推行和项目利用。在本期的问答中，巴纳德博士分享了他对本身的职业生活生计、成绩和水资本将来的看法和思虑。 After finishing my Ph.D. at Vanderbilt in 1971, I returned to the National Water Research Institute in Pretoria (South Africa). The discovery of rich gold deposits more than a century ago resulted in a population of more than 12 million around Johannesburg on the continental divide and Pretoria only 35 miles to the north. This large population concentration at a high altitude where water was pumped from long distances to the emerging cities and while effluents were treated to high standards and returned to the reservoirs that also served as water supply, water treatment standards did not include nitrogen and phosphorus removal. This was causing severe eutrophication (i.e. algae growth oxygen depletion). When observing the green pea-soup overflowing one of these reservoirs, I decided to pursue biological means of removing these nutrients. At the time, practices like chemical treatment and stripping and ammonia were the standard. Biological treatment was still only lab scale. 1971年在范德比尔特年夜学读完博士学位后，我回到了位在比勒陀利亚(南非)的国度水资本研究所。一个多世纪前，南非发觉了丰硕的金矿，使得位在年夜陆分界限上的约翰内斯堡和北部仅35英里处的比勒陀利亚四周的生齿跨越了1200万。生齿集中在高海拔地域，水从很远的处所被泵送到新兴城市，固然污水颠末高尺度处置并前往水库，但水处置尺度不包罗氮和磷的去除。这形成了严峻的富养分化(即藻类发展缺氧)。这形成了严峻的富养分化(即藻类发展缺氧)。当我不雅察到此中一个水库的青豆汤溢出时，我决议采取生物方式去除这些养分物资。那时，化学处置、剥离和氨气等做法是尺度做法。生物处置依然只是尝试室范围。 你职业生活生计中最高傲的时辰/成绩是甚么? This is difficult to say, but two moments stand out. The first is that the city of Johannesburg decided to apply the four-stage process that I developed in the laboratory for the 750,000 PE Goudkoppies Plant; the second was my discovery of biological phosphorus removal in a pilot plant, which Johannesburg also adopted during the construction of the plant. Many were to follow, such as receiving the Water Environment Federation Camp Award, the gold medal of the South African Academy of Science and Arts, the International Water Association Medal (handed over by Princess Anne), and other recognitions. 这很难说，但有两个时辰很凸起。起首是约翰内斯堡市决议采取我在尝试室为75万PE古德科比工场开辟的四阶段工艺;第二个是我在一个实验工场中发觉了生物除磷，约翰内斯堡在工场扶植时代也采取了这类方式。很多人都紧随厥后，例如取得水情况结合会营地奖，南非科学与艺术学院金奖，国际水协会奖章(由安妮公主颁布)和其他承认。 你对这个行业的成长趋向感应兴奋的是甚么? What excites me is how the latest findings are pointing at the possibility of biological nutrient removal (BNR) leading into producing rapid-settling granular sludge which could double the capacity of existing plants while increasing the rate of simultaneous nitrification and denitrification to also achieve very low total nitrogen levels. Then there is the possibility of combining suspended growth with attached growth to get even better results. Our Applied Research team has had some very promising results and I think Black & Veatch will be leading the industry in the future with this. 令我兴奋的是，最新的研究成果注解，生物养分物去除(BNR)有可能发生快速沉淀的颗粒污泥，这可使现有工场的产能翻倍，同时提高硝化和反硝化的速度，也能够到达很是低的总氮程度。然后，有可能将悬浮发展与附着发展连系起来，以取得更好的成果。我们的利用研究团队已获得了一些很是有但愿的功效，我认为博莱克威奇将在将来引领这个行业。 对行业将来的挑战，你对同业们有甚么建议? Be curious and, in the biological world, always remember that nothing happens without a reason. Keep asking 'why.' That's what I did. Whenever I saw something happening, I kept asking 'why' to understand the underlying reason. 连结猎奇心，在生物界，永久记住没有任何工作是没有缘由的。不断地问“为何”。我就是这么做的。每当我看到一些工作产生，我就不竭地问“为何”，以领会此中的缘由。 你最但愿看到的冲破是甚么? One is tempted to say being energy neutral, but that depends a lot on the effluent requirement and geography. But recovery of resources should get preference. The energy that can be recovered especially in colder climates is considerable, and the recovery of nitrogen would be rewarding since the energy required to fix nitrogen from the atmosphere is very high. The one thing that I feel we should look at more is resource recovery, especially protein recovery from food waste and then naturally re-use of the final product. 有人想说能源自给，但这在很年夜水平上取决在污水需乞降地舆位置。但资本收受接管应优先斟酌。特殊是在严寒的天气中，能够收受接管的能量是相当可不雅的，并且氮的收受接管将是无益的，由于从年夜气中固定氮所需的能量很是高。我感觉我们应当更多地存眷资本收受接管，特殊是从食品垃圾中收受接管卵白质，然后天然地再操纵终究产物。 Again, be curious and question everything. Don’t just accept that what’s in the box is final. 再次强调，连结猎奇心，质疑一切。不要只是接管盒子里的工具是终究的。 是不是有一个特殊的时辰，当你反思的时辰，你感觉你帮忙你成立了一个分歧的世界? There were a number of such instances, but the most recent is after I heard about the great performance of the upgradedSacramento Regional Wastewater Treatment Plant. It was such a tight design with everything working so well. The facilities have all but eliminated ammonia and significantly reduced nitrogen in the discharge. Another was when I was honored with a Ph.D. from Iowa State University. 如许的例子有良多，但比来的一次是在我传闻萨克拉门托地域污水处置厂进级后的超卓表示以后。这是一个紧凑的设想，一切都运转得很好。这些举措措施几近消弭了氨，并年夜年夜削减了排放中的氮。另外一个是我被爱荷华州立年夜学授与博士学位的时辰。 All of us at Black & Veatch would like to extend our sincere gratitude to Dr. James Barnard for sharing his valuable insights and expertise with our team and our clients these past 25 years. His contributions to the field of water treatment and pollution reduction have been immense and have helped transform the industry.
