Recovery of nutients from wasterwater

夏洛特敦污染控制厂(CPCP)每年处理约700万立方米的废水，产生约3700吨生物固体。夏洛特敦市计划将其污染控制工厂改造成具有长期经济、环境和社会效益的资源回收设施。**在太阳能、风能和潮汐等各种可再生能源中，将废物转化为有价值的产品**也是关键利益所在。含有大量营养物质的污水排入希尔斯伯勒河会**导致富营养化。富营养化将通过藻类大量繁殖导致生态系统退化，**植物过度生长，氧气耗尽，阳光穿透能力降低，导致**水生动植物多样性丧失。利用生物炭吸附这些养分，不仅可以保护生态系统，还可以回收宝贵的资源，作为肥料用于土地利用。我们将研究生物固体和柳树水热处理后得到的生物炭的吸附性能。**此外，还将研究利用生物炭作为基质培养厌氧微生物来处理废水。

Charlottetown Pollution Control Plant (CPCP) treats approximately 7 million cubic meters of wastewater**annually producing roughly 3700 tones of bio-solids. The City of Charlottetown plans to transform its pollution**control plant into resource recovery facility for having long-term financial, environmental and social benefits.**Among various renewable options like solar, wind and tidal, turning waste streams into valuable products is**also of key interest. Effluent containing high levels of nutrients when discharged into Hillsborough River can**cause eutrophication. Eutrophication will lead to the degradation of the ecosystem through algae blooms,**excessive plant growth, oxygen depletion, and reduced sunlight penetration resulting in loss of diversity in**aquatic plants and animals. Using biochar for adsorbing these nutrients not only protect the ecosystem but also**recover valuable resources that can be used for land application as fertilizer. The adsorption properties of**biochar obtained from hydrothermal pretreatment of biosolid and from willow will be investigated.**Furthermore, the use of biochar as a media to grow anaerobic microbes for the treatment of wastewater will be**studied.
