FIELD: purification of sewage water from sand and other suspended matter, petroleum products, as well as decontamination of cleaned service water in circulating water supply systems at cleaning transport facilities. ^ SUBSTANCE: proposed plant includes hydraulic cyclone, oil separator, thin-layer shelved settler, final cleaning filter with cleaned water reservoir. Hydraulic cyclone is equipped with pipe lines supplying dirty water for cleaning and is communicated with thin-layer shelved settler by means of water discharge pipe line; it is also communicated with oil separator by means of watery petroleum product discharge pipe line. Thin-layer shelved settler is communicated with final cleaning filter by means of water discharge pipe line. Oil separator is communicated with thin-layer shelved settler by means of settled water discharge pipe line. Hydraulic cyclone, oil separator, thin-layer shelved settler and final cleaning filter are communicated with sludge receiver. Floatation unit is arranged in upper part of reservoir where thin-layer shelved settler is mounted. ^ EFFECT: high degree of purification of sewage water in circulating water supply systems at washing transport facilities. ^ 4 cl, 3 dwg |
