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为资源回收设施，以获得长期的财政、环境和社会效益。在各种可再生能源选择中，如太阳能、风能和潮汐能，将废物流转化为有价值的产品也是**的关键兴趣。含有高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、植物过度生长、氧气消耗和阳光穿透减少导致生态系统退化，从而导致水生动植物多样性的丧失。利用生物炭吸附这些营养物质不仅可以保护生态系统，还可以回收可用于土地施肥的宝贵资源。研究了水热预处理生物固体和柳木制备的**生物炭的吸附性能。此外，将研究使用生物炭作为培养基培养厌氧微生物以处理废水。

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.
