Definitions
- the present invention relates to the field of the depollution of water, especially water polluted with hydrocarbons.
- the object of the invention is to propose a device and a method which are simple to implement and which make it possible, in particular, a rapid and continuous cleaning of the water to be cleaned.
- such a device for treating polluted water comprises a pollution control reactor comprising a container in the form of a column, an inlet for polluted water, placed near an upper end of the column, an evacuation for the treated water, disposed near a lower end of the column, an inlet for a sorbent agent, disposed near the lower end and an evacuation for the sorbent agent, disposed near the upper end.
- a pollution control reactor comprising a container in the form of a column, an inlet for polluted water, placed near an upper end of the column, an evacuation for the treated water, disposed near a lower end of the column, an inlet for a sorbent agent, disposed near the lower end and an evacuation for the sorbent agent, disposed near the upper end.
- the discharge of sorbent agent consists of a weir provided for the sorbent is driven by an overflow of water maintained in the column.
- a maximum level of the water supply is less than a minimum level of evacuation for the sorbent.
- a maximum level of the treated water discharge is less than a minimum level of the sorbent inlet.
- the device comprises means for introducing gas bubbles into the treated water, preferably air bubbles, near the bottom of the column, preferably at a level below the arrival of the agent. sorbent, preferably through a bottom of the column.
- the device according to the invention may further comprise several reactors connected in series, the discharge of water from a first reactor being connected to the water inlet of a second reactor.
- a process for the depollution of water is characterized in that:
- a sorbent agent (10), having a lower density than the water to be treated, is introduced into a lower part (7) of the water;
- the sorbent is discharged into an upper part of the water, preferably for recycling and / or recovery.
- the sorbent is an adsorbent polymer.
- Figure 1 is a schematic view of a pollution control reactor according to the invention. invention and a neighboring reactor shown in phantom.
- the figure illustrates a pollution control reactor 1 according to the invention.
- the reactor 1 comprises a column 2 forming a substantially cylindrical container, vertically elongated, open at an upper end and closed by a bottom 3, at its lower end.
- the reactor comprises an inlet 5 for polluted water to be treated and an outlet 6 for the treated water, totally or partially cleaned up.
- the water inlet consists of a pipe opening through a wall of the column, near the upper end of the column 2.
- the evacuation is consisting of a pipe opening through the wall of the column, near the lower end of the column 2.
- the reactor further comprises an inlet 7 for a solid sorbent and an outlet 8 for the sorbent.
- the arrival of sorbent agent comprises an orifice formed through the wall of the column 2, near the lower end of the column 2.
- the evacuation consists of a weir, formed in the upper edge 9 of the column 2.
- the arrival 5 and the evacuation 6 of the water are adjusted so that the water inlet 5 is maintained under the surface 13 of the water.
- the water inlet 5 is disposed below the level of the weir and the water outlet 6 is disposed at a level lower than that of the arrival 7 of sorbent agent. That is, the maximum level N5 of the water supply 5 is below the minimum level n8 of the outlet 8 for the sorbent and the maximum level N6 of the outlet 6 for the treated water is below the minimum level n7 of inlet 7 for sorbent 10.
- the sorbent agent 10 is chosen to have a density significantly lower than that of the water to be treated, whether it is new or after it has adsorbed or absorbed a pollutant from water.
- the sorbent agent 10 is represented by black dots in the figure.
- the reactor 1 also comprises an air inlet 11.
- the air inlet is arranged so that the air comes to form bubbles 12 on the bottom 3, and that the bubbles thus formed rise to the surface 13 of the water.
- the bubbles are represented by circles in the figure.
- the pollution control reactor allows a flow of water from top to bottom and a flow from bottom to top of the sorbent agent.
- the particles of sorbent agent are charged with pollutant. Since the sorbent agent has a lower density than the water it passes through, it naturally rises to the surface 13 of the water. The bubbles make it possible to intensify the rise of the sorbent agent, at the same time as they cause stirring which favors the contact of the sorbent agent with the pollutant to be extracted.
- the reactor advantageously comprises means for adjusting the level 13 of the water, in particular by regulating the flow rate of the outlet 6 as a function of the flow rate of the water inlet 5 and the necessary flow rate of the weir 8, for the evacuation the sorbent agent loaded.
- the sorbent agent is advantageously recycled.
- the recycling of the sorbent is not shown in the figure.
- the sorbent agent can be processed in a centrifuge to be separated from the pollutant. Then, the portion of this sorbent agent that is still usable is preferably reinjected into the reactor 1 and the part that is not reusable can be recovered, for example by incineration.
- a hydrophobic polymer is preferably used in the form of particles or flakes with a high specific surface area.
- a sorbent is described in particular in patent application FR 2 860 732.
- the evacuation 6 of the reactor 1 can be connected to a water inlet 5A of a neighboring reactor 1A.
- the water previously treated by the reactor 1 can be treated again by the reactor 1A.
- This arrangement is particularly advantageous when the treated water is so polluted that the only treatment in the reactor 1 is not sufficient to obtain water of desired quality. It can be expected to mount in series as many reactors as necessary for a complete treatment of water. In the case of a water polluted by multiple pollutants, it can be expected that several successive treatment reactors are each provided to treat a particular pollutant.
- a sensor at each evacuation 6 of a reactor, which examines the quality of the discharged water, and, depending on the quality obtained, directs the evacuated water to a new reactor, for treatment complementary, or not.
- the column can be closed at its upper end, so that a gaseous dome is formed in this upper end and above the liquid surface.
- the upper end then comprises an aspiration for the gases, in order to treat them before discharge into the atmosphere.
- the reactor may further comprise a partition, for example a vertical wall, extending from the bottom of the column to the top of the sorbent inlet, in order to avoid pumping the sorbent through the water discharge. .
- a partition for example a vertical wall, extending from the bottom of the column to the top of the sorbent inlet, in order to avoid pumping the sorbent through the water discharge.
- the vertical column-shaped arrangement also makes it possible to reduce the footprint of the reactor.
- a reactor can be more easily installed on a petroleum platform in order to treat polluted waters with hydrocarbon traces, before discharge to sea.
- a device according to the invention is particularly suitable for the continuous depollution treatment of polluted water, especially water polluted with hydrocarbons.
