摘要/Abstract

摘要： 滨海土壤盐碱化已成为当今世界的重大土地问题之一,如何改良和利用盐碱土成为亟待解决的问题。本文采用经预处理的柠檬酸生产废水对黄河三角洲某滨海油田附近的轻度盐碱化土壤进行灌溉改良,通过改良前后土壤物理化学性质的变化,初步分析柠檬酸生产废水灌溉改良盐碱土的效果和可行性。试验结果表明,经柠檬酸生产废水灌溉45天后,盐碱土的pH值、电导率都有所下降;饱和含水率与清水灌溉相比有较大程度的提高;土壤有机质、总氮等营养成分提高显著。这说明盐碱土的理化性状和营养状况都得到了明显改善。因此,柠檬酸生产废水有望作为盐碱土理化性质的有效改良剂,达到“以废治废”的目的。

Abstract: Coastal soil salinization has become one of the most important land problems all over the world. It is very urgent now to ameliorate and take use of the saline-alkali soils effectively. In this paper,citric acid industrial wastewater after pretreatment was used to ameliorate a saline-alkali soil collected from a coastal oil factory in Dongying City,China. The effects and feasibility of saline-alkali soil amelioration with citric acid industrial wastewater were preliminary analyzed based on the variation of physicochemical properties of the soil before and after irrigation process. Results of the experiments showed that pH and electrical conductivity of soil solution decreased after citric acid industrial wastewater irrigation; saturated water ratio of the soil increased compared to tap water irrigation; organic matter content and the total nitrogen content increased significantly. All the changes indicated that the physicochemical properties and nutrition conditions of the saline-alkali soil were improved after the citric acid industrial wastewater irrigation. It can be concluded that citric acid industrial wastewater may be used as an effective enhancement agent of saline alkali soils, which achieves the goal of “waste treatment by waste”.
