Date Jul. 16, 1998The invention describes a process for the conversion of sewage sludge to humus by a complete filling cycle in a way that in a first cycle a primary polder is filled up to a stated height with sewage sludge. After that, the water content of the liquid sewage sludge in...
The chemical composition of sewage sludge ash(SSA) was tested,and initial SSA was modified to increase the uptake capacity of heavy metal ions before its application. 测试了污泥灰的化学成分并对其进行酸化改性,考察了振荡时间、溶液pH值和反应温度对改性污泥灰去除废水中Cu2+的影响;改性污泥灰对Cu2+的...
From the methanol -sewage sludge- enrichment culture one methanosarcina, two vibrios and one bacteroid have been isolated. 经对该富集培养物的分离培养,已分离出4株厌氧细菌,其中一株为甲烷八叠球菌, 两株为弧菌,一株为杆菌. 互联网 But the contents of phosphorus in coal ash andsewage sludgeare high...
Sewage sludge ash modifies the hydration of cement because of its pozzolanic reaction with portlandite favoring the formation of crosslinked fibrous calcium silicate of low Ca/Si ratio. Hence, it was concluded that thermal damage of cement pastes after the exposure to high treatment temperatures (i....
The porous properties and pozzolanic effects of sewage sludge ash (SSA) make it possible to produce lightweight materials. This study explored the effects of different metallic foaming agents, made from waste aluminium products, on the foaming behaviours and engineering characteristics, as well as the...
Drawing from the sourced literature of 301 publications, produced in 38 countries since 1970, this chapter examines the production of sewage sludge ash (SSA), beginning with the generation of sewage sludge during the wastewater treatment process. The basic physical and chemical properties of the slud...
The chemical composition of sewage sludge ash (SSA) and their sized fractions are studied, some differences in chemical composition are observed. SEM studies show irregular shape of SSA particles and sized fractions, this shape has a decisive influence on workability of mortars. The effect of repla...
Lightweight aggregate made from sewage sludge and incinerated ashIn this study, sewage sludge ash (SSA), with similar characteristics to expansive clay, was used as the principal material and sewage sludge (SS) as the admixture to sinter lightweight aggregate and to study the influences of raw ...
