Supporting of Ecological Safety of Run-off from the Territory of Objects of Road Infrastructure, Contaminated by Petroleum Products

Abstract

In the experimental studies it was found that open run-off settling in comparison with the close settling systems improves the effect of PP disposal by 1.3 times, hexane fraction of PP – nearby 2 times, separate alkanes C22–C27 – by 2–3 times. Duration of open settling of run-off, formed in the territory of suburban parking areas, shall be 3–10 days. The effect of run-off purification from PP under sedimentation is mainly conditioned by disposing of fraction of nominally complex PP.
