摘要 |
<p>In a method and a device for sewage purification, sewage is purified by continuously passing it through several stages of treatment, wherein the passage of sewage is regulated by a process control device and is monitored by sensors. Treatment ensues in physical processing stages, pre-flotation stages, two-step biological clarification stages and one post-flotation stage. The pre-flotation stages as well as the biological clarification stages are each provided with gas-water mixers, and the pre-flotation stages, the biological clarification stages and the post-flotation stage are provided with solid foam separators having outlet channels. Clear water from a clear water overflow basin is supplied to the individual stages through the gas-water mixers and through a clear water return pipe. It is also possible to provide chemical treatment prior to biological clearing, to provide clear water recycling for additional treatment, and to provide solids treatment and a reduction stage. An aquatritor, a bioreactor and a four chamber system are also provided. This method is also suitable for use in a portable device having a compact construction.</p> |
