FIELD: construction.
SUBSTANCE: invention relates to devices of the purification of sewage from petroleum products. The coalescent-sorbent filter for the division of two immiscible liquids with different relative density - petroleum products, which are contained in storm sewage, is executed in the form of a flowing vessel. As the separating element - the coalescent filter uses a layer of liquid with a smaller relative density. The sorbent filter is sunk into the upper part of the specified liquid with a smaller relative density - than the coalescent filter. The sorbent filter is detachable, moving vertically, made in the form of a hollow filled with a filler - a sorbent of capacity and a periphery corresponding to the perimeter of the vessel. The capacity of the sorbent filter additionally contains floats and a regulator of weight and is executed in such a manner that in the passive phase of work of the sorbent filter - without contact of the sorbent with the liquid, the weight of the sorbent filter corresponds or is less than the weight of the displaced capacity of the sorbent filter of the liquid. And in the active work phase of the sorbent filter - with formation of the coalescent filter - a layer of a liquid with a smaller relative density, the sorbent filter is immersed in the coalescent filter.
EFFECT: increase of an overall performance of the coalescent-sorbent filter on sewage purification from petroleum products.
