摘要

由于具有挑战性的土壤和气候条件，农业高度依赖使用水质。因此，本研究调查了中试规模耦合uasb -生物过滤器系统处理后的废水的再利用潜力，该系统利用水牛挤奶过程产生的废水种植耐旱饲料灌木。挤奶女工废水在沉淀池中进行处理，目的是去除较大的悬浮物和可沉降的有机物，然后在上流式厌氧污泥毯（UASB）中进行处理。UASB出水在生物过滤器中进行处理。进行了现场试验的实验农场兽医教员、苏伊士运河大学,从3月到2023年10月来研究不同质量的治疗效果的水牛挤奶女工废水COD (Null, 1000 ± 28日130 ± 33岁520 ± 27日100 ±  30毫克。L−1)对刺槐和辣木灌木生长的影响。分块设计5个处理：每个物种的对照（淡水）（T1）、沉淀池出水（T2）、上流式厌氧污泥毯（稻草生物炭改性UASB）出水单元（T3）、常规UASB出水单元（T4）和生物过滤器出水单元（T5）。测定了营养生长、灌木生物量、土壤氮磷钾、有机质和有机碳。辣木灌木在土壤中的生物量（2330.3 g）和氮含量（62.02 mg kg−1）均高于盐木。UASB处理（T3和T4）促进生长效果最好，处理过的水牛挤奶废水提高了土壤中氮的浓度。综上所述，在沙壤土中，UASB处理对盐渍草和油橄榄灌木的生长最有效。本研究评估了中试规模uasb -生物过滤系统在抗旱饲料灌木栽培中处理废水回用的性能。使用VOSviewer和RStudio 4.4.1进行文献计量分析，基于Web of Science的数据分析1999 - 2024年废水回用研究的趋势。本文综述了可持续农业水文学中废水回用的发展趋势，并强调了有待进一步研究的新兴研究领域。

A green approach to milkmaid wastewater: Evaluating up-flow anaerobic sludge blanket-biofilter effluent for fodder shrubs cultivation and drought resistant

The agricultural industry is highly dependent on using water quality due to challenging soil and climatic conditions. Hence, this study investigated the potential reuse of treated effluents from a pilot-scale coupled UASB-Biofilter system for the cultivation of drought-resistant fodder shrubs using wastewater generated from the buffalo milkmaid process. The milkmaid wastewater was treated in a sedimentation tank, with the aim of removing large suspended solids and settleable organic matter, and then in an up-flow anaerobic sludge blanket (UASB). The UASB effluent was treated in a biofilter. A field experiment was carried out at the Experimental Farm of Veterinary Faculty, Suez Canal University, from March to October 2023 to study the effect of different quality of treated buffalo milkmaid wastewater with COD (Null, 1000 ± 28, 130 ± 33, 520 ± 27, 100 ± 30 mg.L⁻¹, respectively)on the growth of Acacia saligna and Moringa oleifera shrubs. Split plot designed with five Treatments: Control (freshwater) (T1), sedimentation tank effluent (T2), Up-flow Anaerobic Sludge Blanket (modified UASB with rice straw biochar) effluent unit (T3), conventional UASB effluent unit (T4), and biofilter effluent unit (T5), of each species. Vegetative growth, the biomass of shrubs, and the soil NPK, organic matter, and organic carbon were determined. Moringa oleifera shrubs showed higher biomass (2330.3 g)and nitrogen content (62.02 mg kg⁻¹) in soil compared to A. saligna. UASB treatments (T3 and T4) promoted the best growth, with treated buffalo milkmaid wastewater increasing nitrogen concentrations in the soil. Overall, UASB proved to be the most effective treatment for enhancing growth in A. saligna and M. oleifera shrubs in sandy loam soil. This study evaluates the performance of a pilot-scale UASB-Biofilter system for treated effluent reuse in drought-resistant fodder shrubs cultivation. It also conducts a bibliometric analysis using VOSviewer and RStudio 4.4.1, analyzing trends in wastewater reuse research from 1999 to 2024 based on data from the Web of Science. The review provides insights into the evolution of wastewater reuse in sustainable agro-hydrology and highlights emerging research areas for further investigation.
