Príklad uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Je znázornené zariadenie na spracovanie skôr biologicky spracovaných odpadových vôd, ktoré v podstate pozostáva z reakčných nádrží 1.2, výrobníka 8 ozónu, nádrže 4 odplynenia a IJV-reaktora 5. Podľa vynálezu budú nádrže i, 2 pracovať s pribúdajúcim tlakom v smere prúdenia odpadových vôd, a to prvá reakčná nádrž i s tlakom 5 barrov a druhá reakčná nádrž·2 s tlakom 7 barrov.An apparatus for treating previously biologically treated waste water is shown, which essentially consists of reaction tanks 1.2, ozone generator 8, degassing tank 4 and an IJ reactor 5. According to the invention, tanks 1, 2 will operate at increasing pressure in the direction of wastewater flow. the first reaction tank with a pressure of 5 bar and the second reaction tank · 2 with a pressure of 7 bar.
Vopred biologicky spracovaná odpadová voda sa privedie do zariadenia prívodným vedením 6 a uvedie ša čerpadlom 7 na tlak 5 barrov. Privedie sa do prvej reakčnej nádrže L, ktorej plniaci stav sa reguluje regulátorom 8 plniaceho stavu a regulačným ventilom 9. Podľa vynálezu sa do prvej reakčnej nádrže 1 privedie vedením 10 ozónu v protiprúde k odpadovej vode plyn obsahujúci ozón. Zvyškový plyn opúšťa priestor hlavy prvej reakčnej nádrže i vedením 11 zvyškového plynu.The pre-treated waste water is fed to the plant via a feed line 6 and brought through a pump 7 to a pressure of 5 bar. It is fed to a first reaction tank L, the filling state of which is controlled by the filling state regulator 8 and the control valve 9. According to the invention, a ozone-containing gas is supplied to the first reaction tank 1 in a countercurrent flow to the waste water. The residual gas leaves the head space of the first reaction tank through the residual gas line 11 as well.
Z prvej reakčnej nádrže 1_ prúdi odpadová voda regulačným ventilom 9 & odvodným vedením 12 do nádrže 4 odplynenia, kde sa oddifľuje zvyškový plyn obsahujúci ozón a privádza sa spojovacím vodením 13 do zariadenia 14 rozkladu ozónu. Odplynená odpadová voda sa z nádrže 4 odplynenia vedie druhým spojovacím vedením 15 do UV reaktora 5 a pomocou druhého čerpadla 16 sa stlačí na tlak 7 bánov. Odtiaľ prúdi tretím spojovacím vedením 17 do druhej reakčnej nádrže 2. Čast odplynenej odpadovej vody sa odvádza ako úplne spracovaná odpadová voda odvodným ventilom 18 a výstupným vedením 19. Plniaci stav v nádrži 4 sa nastaví regulátorom 20 plniaceho stavu.From the first reaction tank 7, the waste water flows through the control valve 9 through the discharge line 12 to the degassing tank 4, where the ozone-containing residual gas is separated and fed via the connecting line 13 to the ozone decomposition device 14. The degassed waste water from the degassing tank 4 is passed through a second connecting line 15 to the UV reactor 5 and is compressed to a pressure of 7 by means of a second pump 16. From there it flows through the third connection line 17 to the second reaction tank 2. Part of the degassed waste water is discharged as completely treated waste water via the outlet valve 18 and the outlet line 19. The filling state in the tank 4 is adjusted by the filling state controller 20.
Z druhej reakčnej nádrže 2 sa odpadová voda odoberá druhým odvodným vedením 21 a pomocou tretieho čerpadla 22 sa zvyšuje tlak. v injektore 23 sa upravuje zmesou ozón - kyslík a štvrtým spojovacím vedením 24 sa znova zavádza do druhej reakčnej nádrže 2. Cast odvodnej vody sa pred injektorom 23 odvádza piatym spojovacím vedením 25 a ventilom 26 do prvej i?eakčnej nádrže 1. Plyn z hlavy druhej reakčnej nádrže 2 sa podľa vynálezu vedením 10 ozónu na základe tlakového spádu zavádza cez filtračnú dosku do prvej reakčnej nádoby 1. Plniaci stav v druhej reakčnej nádrži 2 sa reguluje druhým regulátorom 29 plniaceho stavu.From the second reaction tank 2, the waste water is taken off by the second drain line 21 and the pressure is increased by the third pump 22. in injector 23 it is treated with an ozone-oxygen mixture and recirculated through the fourth connecting line 24 to the second reaction tank 2. Part of the effluent before the injector 23 is discharged through the fifth connecting line 25 and the valve 26 into the first reaction tank 1. According to the invention, the reaction tank 2 is fed through a filter plate to the first reaction vessel 1 via a pressure gradient 10 via a filter plate. The filling state in the second reaction tank 2 is controlled by the second filling state controller 29.
Zvyškový plyn odobraný z prvej reakčnej nádrže 1 vedením li zvyškového plynu prúdi sušiakom 27, mieša sa s kyslíkom z vedenia 28 kyslíka a vo výrobníku 3 ozónu sa znova čiastočné premení na ozón.The residual gas removed from the first reaction tank 1 flows through the residual gas line 11 through a dryer 27, mixed with oxygen from the oxygen line 28 and is partially converted to ozone again in the ozone generator 3.
