Abstract:

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.

Key words: Laboratory acidic waste liquid, Saline-alkali soil, Improvement, Application prospect
