Abstract

A rain water purification system includes a water discharge collector connected to a collector of industrial-and-domestic sewage, a reservoir for rain water purification with vertical partitions, a settling chamber with a pipeline for discharge of oil products from surface, an overflow chamber connected to the settling chamber by means of an overflow opening and a collector for rain water discharge to a water body. To increase efficiency of purification due to regeneration of filtering bed at continuous purification mode the reservoir for rain water purification is equip[ed with a filtering chamber and filtering bed. The bottom of filtering bed is connected to the collector of industrial-and-domestic sewage by means of a pipeline. The pipeline is equipped with a shutoff unit that interacts with level probes located in the overflow and filtering chambers. The overflow chamber is equipped with vertical pipeline and siphon one with air pipe. The upper end of vertical pipeline is located lower than the overflow opening and is equipped with a float shutoff unit, and the lower end is connected to the filtering chamber trough the bottom opening.
