实验室酸性废液在盐碱土改良中的应用前景

Application prospect of laboratory acidic waste liquid in the improvement of saline-alkali soil

盐碱土是一类因其理化性质和肥力问题而生产力极低或暂无生产力,但具有改良利用价值的后备耕地或草地资源。实验室废液是实验室在测试分析过程中产生的具有强酸性但含有较多营养元素的废弃液体。文章阐述了盐碱土的改良利用现状和实验室废液的来源与特点,并介绍了实验室废液无害化处理方法和实验室酸性废液在盐碱土改良中实际应用的可能性及具体案例,最后展望了实验室废液无害化处理和资源化利用的应用前景。

Saline-alkali soil is a type of reserved farmland or grassland resource with poor or no productivity due to its physical,chemical properties and fertility issues,but has potential for improvement.The waste liquid created by laboratory during testing and analysis is known as the laboratory liquid waste,which is typically very acidic yet contains lots of nutrients.This paper described the current state of saline-alkali soil improvement and resource utilization as well as the sources and characteristics of laboratory liquid waste,introduced harmless treatment options for laboratory waste liquid,as well as the potential and specific cases of laboratory acidic waste liquid practical application in saline-alkali soil improvement,finally,looked forward to the application prospects of harmless treatment and resource utilization of laboratory waste liquid.
