Abstract
The invention relates to a treatment installation consisting of one or more compartments (2) connected in parallel, which compartments are provided with inlets (1, 3) and outlets (6, 7) and can contain a filling of a support material (2a) on which and between which microorganisms are present, which installation is constructed in such a way that both (polluted) air (1) and (polluted) water (3) are passed downwards through the support material (2a) with a hydraulic surface loading selected between 0.5-30 m3/m2/h, wherein the pollutants are converted by the microorganisms, and air forms the continuous phase. The installation is advantageously constructed in such a way that the support material can be rinsed (8-10), while it can also be advantageous to provide facilities for the pretreatment of the air and/or water to be supplied and for subsequent treatment of the other stream of water and air obtained.
Claims
AMENDED CLAIMS
[received by the International Bureau on 3 December 1993 (03.12.93); original claim 1 amended; original claim 6 deleted; original claims 7-15 renumbered as claims 6-14; new claim 15 added (2 pages)]
1. Treatment installation consisting of one or more compartments connected in parallel, which compartments are provided with inlets and outlets and contain a filling of a support material, on which and between which microorganisms are present, characterised in that the installation is constructed in such a way that both (polluted) air and (polluted) water are passed downwards through the support material (2a) with a hydraulic surface loading selected between 0.5_30 m3/m2/h, wherein the pollutants are converted by the microorganisms, and wherein air forms the continuous phase and constructed in such a way that the support material can be rinsed.
2. Installation according to Claim 1, characterised in that the installation is constructed such that the hydraulic surface loading is selected between 5~15 m /m2/h.
3. Installation according to Claim 1 or 2, characterised in that the installation is constructed such that the air/water ratio (the feed) is at least 0.1 and at most 1, preferably between 0.3-0.5 for purification of water. . Installation according to claim 1 or 2, characterised in that the installation is constructed such that the air/water ratio (the feed) is at least 2 and at most 30, preferably between 5_1 for purification of a combination of air and water.
5. Installation according to any of the preceding claims, characterised in that the installation is constructed such that the hydraulic residence time based on the volume of water present is between 1-10 minutes, preferably between 1.5~3 minutes.
6. Installation according to any of the preceding claims, for the treatment of effluent, if desired together with ground air, characterised in that a buffer vessel (14), which is designed as an oil/sand separator, is placed upstream of the reactor (2). 7« Installation according to any of the preceding claims, characterised in that a system for the removal of chemical precipitates from the liquid phase is inserted upstream of the biological reactor(s) .
8. Installation according to any of the preceding claims, characterised in that said installation is constructed in such a way that
the effluent can be recycled.
9. Installation accordi: _. to any of the preceding claims, characterised in that the installation contains one or more reactors (2) placed in series. 10. Installation according to any of the preceding claims, cha¬ racterised in that a connection for the supply of air is fitted in the feed line for the water to be treated (3) •
11. Installation according to any of the preceding claims, characterised in that the installation is constructed in such a way that the process air is removed via the same line as the treated water.
12. Installation according to any of the preceding claims, cha¬ racterised in that a facility is provided for the after-treatment of discharging water and/or air streams.
13. Installation according to any of the preceding claims, characterised in that a grating (18) is fitted in the top of the reactor, through which grating the rinse water and the rinse air are separated when rinsing back the support material (2a) .
14. Method for the treatment of water and/or off-gases, characterised in that an installation according to any of the preceding claims is used.
15. Method for the treatment of water in particular ground water, optionally in combination with off-gases, characterised in that an installation according to any of claims 1-14 is used.
