With the development of the paper industry, the problem of alkaline peroxide mechanical pulp (APMP) pulping effluent treatment is based on major issues. Currently, using APMP pulping effluent to prepare animal feedstuff is a research hotspot. The Aspergillus niger S13 aerobic fermentation was followed by a post-coagulation/flocculation process for the treatment of APMP pulping effluent. As the by-product, the biomass from the A. niger S13 aerobic fermentation process was assessed as a potential feedstuff. The nutrient contents and heavy metal contaminants of the prepared feedstuff were analyzed and compared with other feedstuff or bio-production from the literature. The toxicity of the prepared feedstuff was also assessed through Sprague-Dawley rat experiments. The research found that the prepared feedstuff was a nontoxic and safe nutritious material. It is worth noting that the prepared feedstuff also exhibited other attractive properties, such as the presence of miscellaneous and benign enzymes and lignin, which is very beneficial to the diet efficiency of animals. This study provides a facile and sustainable approach to harvest versatile and available feedstuff from APMP pulping effluents.

随着造纸工业的发展，碱性过氧化物机械纸浆（APMP）制浆废水的处理问题是基于主要问题的。当前，使用APMP制浆废水制备动物饲料是研究热点。该黑曲霉S13好氧发酵随后为APMP的制浆流出物中的一个处理后的凝结/絮凝过程。作为副产物，来自黑曲霉S13的生物质有氧发酵过程被评估为潜在的饲料。分析了所制备饲料的营养成分和重金属污染物，并将其与其他饲料或文献中的生物制品进行了比较。还通过Sprague-Dawley大鼠实验评估了所制备饲料的毒性。研究发现所制备的饲料是一种无毒且安全的营养物质。值得注意的是，制得的饲料还表现出其他吸引人的特性，例如存在杂，良性酶和木质素，这对动物的饮食效率非常有益。这项研究提供了一种简便而可持续的方法，可以从APMP制浆废水中收获通用的可用饲料。
