CLEANING INSTALLATION OF STORM WATER SEWAGE IN URBAN TERRAIN

摘要

FIELD: construction.;SUBSTANCE: storm discharge from drain header 1 is sent to receiving and settling chamber 2. Via filtration dam 3 the drain arrives to section of cleaning 4 arranged as a shallow bio-plateau with air and water vegetation. During spring flood, the drain via a groove in the side part of cleaning section 4 is sent to bypass channels 9. Bypass channels 9 are arranged with air and water vegetation and are installed between a cleaning section 4 and water object 8. Part of drain via filtration dam 5 arrives to additional cleaning section 6 arranged in the form of deep-water pool with water vegetation. Then via filtration dam 7 the drain is discharged into water object 8.;EFFECT: invention improves efficiency of storm discharge cleaning.;5 dwg
