METHOD FOR PREVENTIVE PROTECTION OF WATER BODY FROM POLLUTION WITH LIQUID HYDROCARBONS Russian patent published in 2017 - IPC C02F1/28 E02B15/04 

FIELD: ecology.

SUBSTANCE: invention relates to environmental protection and can be used for advanced-preventive protection of a water body from liquid hydrocarbon pollution, as well as during seasonal protective measures. Method involves treating the water body with liquid hydrocarbon adsorbents, which have been packed, using a certain method, into shell-bags, permeable for water and liquid hydrocarbons; bags with hydrophobic adsorbent inside – graphene pumice – are dumped onto the water surface in or near the source of water discharge at a hydraulic engineering installation to provide advanced preventive protection of water body while the bags are floating in the water using the current; or the bags that have been attached to each other or placed in a net together with a load and, possibly, anchor, are placed at the bottom of the protected water body for cleaning the bottom deposits from heavy hydrocarbons -once on the water surface, freely floating bags clean the protected water body and even collect the contaminant, which is not known to have been dropped into the water yet, wherein the neutralization of the contaminant is performed by hydrocarbon-oxidizing natural bacteria present in any aquatic ecosystem or under other natural factors - in the pores of the adsorbent, which do not shrink under the action of capillary forces, and the bags, cleaned from the contaminant and able to move further, float to another contaminated section of the water surface and the cycle is repeated multiple times.

EFFECT: invention provides protection of a water body from pollution by liquid hydrocarbons.
