Green Building Materials Turning Waste Sludge into Building Materials(2009/9/11)

Sewage treatment plants in sewage treatment process, tend to produce large amounts of sludge. How harmless sludge treatment, many companies have tried many ways, with fertilizer, fuel. Finally a sewage treatment plant found a way that the sludge processed into building materials.

January 16, reporters in the brick sewage treatment plant sludge plant to see the workers put out of the sludge sedimentation tank, according to a certain ratio and sand mixture, pressing into the template, and add additives, the paste not on the wall of sludge has become a part of the building. Workshop piling up many of the manhole, dow tile, curb and other building materials are made of such a product.

It is understood that it is more or less on the cost of mud brick and the ordinary coal ash brick making, but the strength of the product have to more than ordinary products. The original sewage treatment plant daily to produce 8-10 tons of sludge, which sludge transported to the processing company specialized sound processing also need a fee, and now the introduction of conversion and curing of sludge reuse of patented technology , not only is turning waste into treasure, but also for savings in sewage treatment plant sludge disposal costs a lot.
