INSTALLATION FOR PURIFICATION OF FIELD WASTE WATERS Russian patent published in 2005 - IPC

FIELD: settling tanks for field waste waters purification.

SUBSTANCE: the invention is pertaining to the field of waste waters settling tanks and may be used for purification of the fat-containing and petroleum-containing waste waters from the pop-up and settling pollutions. The waste waters aeration is exercised directly in the cylindrical body using the ejecting heads located at a sharp angle to the water plane. The jet water distributor is not mechanically coupled to the separate members of the installation due to utilization of a floater. The shaft in the floater is installed with a capability of movement along the vertical axis. It is possible to change the height of location of the ejecting heads and nozzles in respect to the water plane in the vertical cylindrical body by moving the shaft in the floater along the vertical. In result the process of purification of waste water is intensified due to variation of the hydraulic characteristics of the dropping spray on the water plane, therefore is stimulated is in vertical direction possible. By changing the waste water spray dropping angle from the ejecting heads on the water plane it is possible to change the angular rate of rotation of the water distributor an in result the process of waste water purification therefore is intensified.

EFFECT: the invention ensures intensification of the waste water purification process.
