Process and plant for the creation of an alternative treatment plant for the treatment of municipal, industrial and agricultural wastewater and sludge

摘要

Wastewater treatment has a tradition that goes back 150 years. During this time a process has developed which is considered to be the state of the art. Although this method meets the requirements, it is complicated and expensive. The new process breaks up the rigidly established technology and simplifies it. In several process stages only gravity is used as the only energy that is available everywhere and does not cost anything. In this way, an "alternative sewage treatment plant" was created which, with the same capacity, is simpler in the process and cheaper in terms of investment and operating costs and requires only a fraction of the space previously required. The most important feature of the invention is that the fibrous materials are separated from the wastewater using a new method immediately after entering the sewage treatment plant. The mechanically cleaned water can be cleaned faster, easier and cheaper. Schls is also looking at new ways of energy carriers or materials that should be used accordingly. According to the invention, the prerequisite for using the sludge is also created by drying it economically to 95-98% DM.
