system of treatment and recovery of heavy metals and hydrocarbons from contaminated sludges and solids from liquids

摘要

the method is simple in process and low cost, the processing for hydrocarbon recovery and heavy metals from water, sludge and solid dedeblais contaminated.the method includes: a means for: - in the first stage of oil by mechanical shaking it by the rotation of a propeller.the process of steam injection, and with the addition of a product desemulsifiant; in the second phase of receuperer heavy metals from the contaminated water by lime addition on the harmonization and the use of the rotation of the helix; additive injection system (na2so4) purpose to enhance the recovery of heavy metals; and a buffer tank is used for.the water forms by reaction precipitates would like lac / na2so4 and buffer system for the pumping of water to a filter system for filtering fuel system; a buffer from the tank via a pumping system consisting of two centrifugal pumps.
