Sewage engineering

from Wikipedia, the free encyclopedia

Wastewater technology is a generic term for technologies in dealing with wastewater (including rainwater ): wastewater collection, wastewater discharge and wastewater treatment in the course of wastewater disposal .

Sewage technology in urban water management

This includes techniques for storing, transporting and cleaning wastewater, which are linked to measurement and control technology. If necessary, technologies for energy recovery must also be included. This means that wastewater technology is increasingly becoming a cross-sectional technology, the processes of which cannot be assigned to either an industry or a technological core area.

With regard to the technology for cleaning wastewater, in recent years there have been mechanical ( rake , sand trap and settling basins ) and biological processes (e.g. activated sludge ) as well as chemical processes (e.g. precipitation of phosphate ) and the use of membrane filters kicked. Central and decentralized applications (e.g. small wastewater treatment plant ) are possible.

Wastewater technology in urban water management is part of civil engineering .

Sewage and drainage technology in building services

The aim here is to drain the accumulating sewage and rainwater in drainage systems from the house, the commercial or industrial enterprise without any disturbance; As a rule, wastewater or rainwater is discharged into the public sewer system. A distinction must be made between the separation system and the mixed system . Harmful substances must be reliably retained, backflows due to high levels of precipitation must be avoided and, at the same time, proper operation must be maintained.
Serve lifting systems , backflow , oil separators , grease traps and other facilities.

Cable routing, cable dimensioning and choice of materials correspond to DIN 1986 and DIN EN 12056.

In addition, systems for rainwater infiltration and rainwater harvesting are increasingly being used.
