FIELD: purification of the surface water runoff; production of installations for purification of the surface water runoff in settlements and industrial enterprises. ^ SUBSTANCE: the invention is pertaining to the field of the equipment for purification of the surface water runoff, in particular, to the installations for the surface water runoff purification from mechanical impurities and petroleum in settlements and industrial enterprises - especially those allocated in conditions of shortage of free areas, and also drainage waters. The installation for purification of the surface water runoff contains: the lifting-adjusting reservoir with the headrace collector and the overflow pipeline; the body divided by the longitudinal partitions into the storing chambers; the pure water chamber and the settling chamber supplied with the means for removal of settling and the pop-up pollutions; the siphons mounted in one section of the chambers, the water-raising pumps, the screens with the grainy loading, the pipelines for feeding and withdrawal of the waters, the sediment and floating matters, the unit of sediment dehydration, the vertical netted shaft. The storing up chamber adjacent to the settling chamber is divided for two intercommunicating sections. The settling chamber is supplied with the stream-guiding partition and the rigidly fixed chutes. The settling chamber and the first section of the adjacent storing up chamber have the common fittings for withdrawal of the floating matters. In the last storing up chamber there is the overflowing pipeline. In the chamber of the pure water there are the gravitational grainy screens of the first stage with the pipelines and the collecting tank of the purified water. The pressure grainy screens of the second stage are arranged above the lifting-adjusting reservoir and the storing up chambers. The technical result of the invention is the improved quality of the purified water and decreased power input. ^ EFFECT: the invention ensures improved quality of the purified water and decreased power input. ^ 8 cl, 3 dwg |
