Environmental consequences of high productivity piggeries are significant and can result in negative environmental impacts, hence bioremediation techniques (in particular using macroalgae) are therefore of great interest. Here, the growth potential of several freshwater macroalgae in anaerobic digestion piggery effluent (ADPE), their nutrient removal rates and biochemical composition of the biomass were investigated under outdoor climatic conditions. A consortium of two macroalgae, Rhizoclonium sp. and Ulothrix sp. was isolated and could efficiently grow in the ADPE. Maximum ammonium removal rate (30.6±6.50mg NH-NLd) was achieved at ADPE concentration equivalent to 248mgNH-NL. Mean biomass productivity of 31.1±1.14g ash-free dry weight (AFDW) md was achieved. Total carbohydrate and protein contents ranged between 42.8-54.8 and 43.4-45.0% AFDW, respectively, while total lipid content was very low. The study indicates the potential use of this macroalgal consortium for treating ADPE as well as source of animal feed production.
高生产力养猪场的环境后果是重大的，可能导致负面的环境影响，因此生物修复技术（特别是利用大型藻类）具有很大的意义。在这里，在户外气候条件下，研究了几种淡水大型藻类在厌氧消化养猪场废水（ADPE）中的生长潜力、它们的养分去除率和生物质的生物化学组成。两种大型藻类（Rhizoclonium sp.和 Ulothrix sp.）的混合物被分离出来，并能在 ADPE 中有效生长。在 ADPE 浓度相当于 248mgNH-NL 的情况下，达到了最大的铵去除率（30.6±6.50mg NH-NLd）。平均生物量生产力为 31.1±1.14g 无灰干重（AFDW）md。总碳水化合物和蛋白质含量分别在 42.8-54.8%和 43.4-45.0% AFDW 之间，而总脂质含量非常低。该研究表明，这种大型藻类混合物具有处理 ADPE 以及动物饲料生产的潜力。
