垃圾填埋场渗滤液调节池污泥固化处置
Solidification Disposal of Sludge from Landfill Leachate Conditioning Ponds
摘要
Abstract
[Objective]In recent years,the amount of municipal garbage and waste has been increasing with social progress,and a large amount of sludge by-products are produced when underground landfill is used to treat urban waste.The production of sludge increases year by year,and requires large storage costs,the accumulation of sludge will also affect the nearby soil and air,how to deal with waste sludge has become a key issue to limit the development of the city.[Methods]This paper described the principles of sludge curing agent selection and curing mechanism,analyzed the impact of different curing agents on sludge curing effect,combined with a landfill leachate conditioning pond in Shenzhen,sludge properties,cement as the main curing material designed four groups of different rapid curing test program for field tests,the sludge curing products,including the no-limit compressive strength,acidity,alkalinity,and water content,etc.,and studied the effect of different curing agents on high sludge production,and the impact of different curing agents on high sludge production.The curing effect of different curing agents on sludge with high water content,high organic matter and high heavy metal content was investigated.[Results]Using cement and quicklime as the curing agent and mixing 28%of mass fraction was less costly,and the water content of the cured product after 2 days of maintenance was 51%,the pH value was 9,which was weakly alkaline,and the unconfined compressive strength reached 80 kPa,which was able to quickly meet the standards and engineering requirements for sanitary landfills.[Conclusion]This program provides a rapid test idea of landfill leachate conditioning pond sludge curing,and puts forward an industrially applicable sludge rapid curing program,which provides a reference basis for solving sludge disposal problems.关键词
