The experimental study on utilization of the urban sewage sludge in the process of sintering brick with fly-ash and clay
粉煤灰-粘土砖烧制过程处理城市污水污泥的试验研究

Possible utilization of urban sewage sludge, in the process of produetion of sintering brick with fly-ash and was investigatel. The results showed that the burning capacity of coal is raised and improved by adding 20 percent urban sludge containing 80 percent water into the coal. It did not affect the qualities of the sintering end products by adding 30 percent urban sludge contained 80 percent water into the fly-ash and clay. The 50 percent of urban sludge can be consummed in this process.
