Abstract

Water scarcity affects more than 40% of the population; in addition, 70% of all water extracted from aquifers is used for irrigation, reducing its availability for human consumption. Therefore, irrigation of crops with wastewater helps reduce water scarcity. In Mexico, high chemical oxygen demand (COD)-value wastewater is generated by the cooking process of corn (Zea mays). In this work, the use of this effluent for the irrigation of potato crops (Solanum tuberosum) is proposed. Four treatments were applied: (A) water, (B) water with fertiliser, (C) 100% wastewater and (D) 50% wastewater, both residual effluent of the cooking corn process. In the determination of biomass, in the number of leaves, there were no differences between the treatments; instead, for the height of the plants, A and B were higher for day 32. Treatment B obtained the highest production of tubers, followed by treatment A. Treatment C achieved 80% of the production of treatment A, suggesting that the components of the wastewater can be used as nutrients by potato plants. Being necessary for a study on the affectation on soil fertility, the use of treated wastewater to irrigate crops represents a viable alternative to reduce the effluents commonly discharged into natural spaces. Furthermore, if the composition of the treated wastewater is known, a water resource added with the compounds present that can improve the crop can be offered as a source of water to mitigate its increasingly high scarcity worldwide.

将玉米工业废水用作马铃薯作物(Solanum tuberosum)灌溉水的效果
缺水影响到 40% 以上的人口;此外,从含水层提取的水有 70% 用于灌溉,减少了供人类消费的水量。因此,用废水灌溉农作物有助于缓解缺水问题。在墨西哥,玉米(Zea mays)的蒸煮过程会产生高化学需氧量(COD)废水。在这项工作中,提出了利用这种废水灌溉马铃薯作物(Solanum tuberosum)的建议。采用了四种处理方法:(A) 水,(B) 含有肥料的水,(C) 100% 的废水和 (D) 50% 的废水,这两种废水都是蒸煮玉米过程中产生的残留废水。在测定生物量和叶片数量时,各处理之间没有差异;相反,在植株高度方面,A 和 B 处理在第 32 天较高。处理 B 的块茎产量最高,其次是处理 A。处理 C 的产量是处理 A 的 80%,这表明废水中的成分可被马铃薯植物用作养分。由于有必要研究废水对土壤肥力的影响,使用处理过的废水灌溉作物是减少通常排入自然空间的污水的一种可行替代方法。此外,如果知道经过处理的废水的成分,就可以将添加了可改善作物生长的化合物的水资源作为一种水源,以缓解全球日益严重的水资源匮乏问题。
