    再生水灌溉对玉米和大豆品质影响的试验研究

    Effects of reclaimed wastewater irrigation on the quality of maize and soybean

    • 摘要: 为了合理利用城市污水处理后的再生水资源,研究再生水灌溉对作物品质的影响,该文采用北京高碑店污水处理厂的两种再生水(二级再生水、三级再生水),以清水为对照进行玉米和大豆盆栽种植试验。通过对籽粒常规养分、微量元素和重金属含量等项目的测定分析,对再生水灌溉情况下的作物品质进行研究。研究结果表明:再生水灌溉对玉米和大豆籽粒粗蛋白、粗淀粉含量无显著影响;在微量元素方面,对大豆籽粒的影响同对照差异不显著,而对玉米籽粒的影响同水质有关;玉米和大豆籽粒中的重金属铅、镉含量虽均低于国家卫生标准(GB 2715-1981)规定,但二级再生水灌溉的玉米镉含量相对对照增加显著。因此认为三级再生水相对二级再生水应用于作物灌溉更具安全性,对二级再生水中重金属镉含量应严格控制。

       

      Abstract: In order to rationally use the reclaimed wastewater after treated wastewater, the potted experiment was conducted to investigate the effect of different reclaimed wastewater(second effluent water and tertiary effluent water from Beijing GaoBeiDian wastewater treatment plant) irrigation on the quality of maize(NongDa 108) and soybean(Zhonghuang 13). The experiment was designed to study the crop quality through measuring the general quality indexes,some heavy metals and microelements. Results show that, on the quality of crude protein and crude starch, no significant differences are observed between the control of fresh water irrigation and the treatments of reclaimed wastewater irrigation. On microelements, there are not significant differences between the control and reclaimed wastewater treatments for soybean grains while the influence is related to the reclaimed wastewater quality for maize. The cadmium and lead contents of maize and soybean meet the national sanitation standard(GB 2715-1981). Compared with the control treatment, the content of cadmium of maize increases under the second effluent water treatment. So it is considered that the tertiary effluent water is much safer than the second effluent water when used in crop irrigation and it is strongly suggested that there should be a continuous monitoring of the second effluent water quality of cadmium content.
