摘要

利用厌氧消化技术处理有机废物是一种前景广阔且成熟的有机废物管理方法。然而，厌氧消化产生的废水由于铵含量高，排放风险很大。微藻类是去除这些氮的重要解决方案。这项工作旨在评估三种北欧微藻菌株（Chlorella vulgaris、Chlorococcum sp.和 Coelastrella sp.）在不同浓度的城市污水污泥厌氧消化废水中的生长情况。由于氨含量较高（分别为 600 毫克/升和 400 毫克/升），没有一个菌株能够在稀释 2 倍（X2）或 3 倍（X3）的污水中生长。虽然 Chlorococcum sp.在 5 倍（X5）和 7 倍（X7）稀释的污水中分别出现了 7 天和 11 天的滞后期，但该菌株在 15 天后的总氨氮（TAN）去除率分别为 53% 和 86%；在 X10 中，其总氨氮去除率为 100%。在没有任何滞后期的情况下，Coelastrella sp.在 X5 和 X7 中的总氨氮去除率与 Chlorococcum sp.相同，但 C. vulgaris 在 X5（90%）和 X7（90%）中的总氨氮去除率最高。此外，该菌株在所有培养基中的生物量干重产量最高（X5 中为 1.1 g L-1）。因此，C. vulgaris 和 Chlorococcum sp. 是脱氮和可持续藻类生物质生产的理想候选菌株，可通过将废物流转化为资源，缓解北欧国家厌氧消化废水的环境问题。

Total ammonia removal from anaerobic digestion effluents of municipal sewage sludge using Nordic microalgae

The treatment of organic waste using anaerobic digestion is a promising and well-matured organic waste management method. However, the effluent from anaerobic digestion has a significant discharge risk due to its high ammonium content. Microalgae could be a valuable solution to remove this nitrogen. This work aimed at evaluating the growth of three Nordic microalgae strains (Chlorella vulgaris, Chlorococcum sp. and Coelastrella sp.) in different concentrations of effluent from anaerobic digestion of municipal sewage sludge. None of the strains was able to grow in effluent diluted two times (X2) or three times (X3) due to the high ammonium content (600 and 400 mg L⁻¹, respectively). While Chlorococcum sp. showed a lag phase of 7 and 11-days in 5 times (X5) and 7 times (X7) diluted effluent, respectively, this strain demonstrated 53 % and 86 % total ammonia nitrogen (TAN) removal efficiency after 15 days; in X10 its TAN removal was 100 %. Without any lag phase Coelastrella sp. showed the same TAN removal efficiencies in X5 and X7 as Chlorococcum sp. However, C. vulgaris had the highest TAN removal in X5 (90%) and X7 (90%). Furthermore, this strain showed the highest amount of biomass dry weight production in all media (1.1 g L⁻¹ in X5). Therefore, C. vulgaris and Chlorococcum sp. are promising candidates for nitrogen removal and sustainable algae biomass production, resulting in mitigating the environmental issues of anaerobic digestion effluents in Nordic countries through the conversion of waste streams into resources.

期刊介绍： Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
