Physicochemical Properties and Recycling Technology of Bottom Ash of Sewage Sludge Incineration
摘要
Abstract
The problem of disposal and utilization of bottom ash of sewage sludge incineration in sludge incineration process must be solved. In this paper,the physicochemical properties in terms of particle size,shear,compression consolidation,permeability,heavy metals content of two different kinds of bottom ash of sewage sludge incineration were studied and compared with the original sewage sludge properties to analyze the effect of incineration on sewage sludge treatment. The reuse technology of bottom ash of sewage sludge incineration was also explored based on its physicochemical properties. The results show that bottom ash of sewage sludge incineration belongs to sandy soil,and the shear strength significantly increases after the incineration,which can reach 76. 23 ~80. 03 kPa;the heavy metal content is over standard,while the heavy metal leaching amount is less than the corresponding standard limit. It can be used in subgrade materials,CO2 capture and sea reclamation.关键词
