Description
Nærværende oppfinnelse vedrører en fremgangsmåte for å bestemme innholdet av oksyderbare organiske forbindelser eller stoffer som er løst, blandet eller dispergert i et væske-og/eller gassmedium. The present invention relates to a method for determining the content of oxidizable organic compounds or substances that are dissolved, mixed or dispersed in a liquid and/or gas medium.
For å bestemme f.eks. mengde av kjemisk oksyderbare organiske stoffer i vann anvendes i dag hovedsakelig to prinsipielt ulike metoder. Den ene metoden består i at prøveløsningen titreres med en standardløsning bestående av kaliumpermanga-nat eller kaliumdikromat. Ulemper med disse titreringsmeto-der er at også uorganiske stoffer samtidig blir oksydert, To determine e.g. quantity of chemically oxidizable organic substances in water, mainly two fundamentally different methods are used today. One method consists in the test solution being titrated with a standard solution consisting of potassium permanganate or potassium dichromate. Disadvantages of these titration methods are that inorganic substances are also oxidized at the same time,
og at metodene krever en viss tid og en ikke ubetydelig ar-beidsinnsats på et laboratorium. Metoden har dessuten ikke latt seg automatisere. En annen metode, som i den senere tid har kommet til anvendelse, består i at en uttatt prøve blir gjenstand for en forbrenningsreaksjon ved høyere tem-peraturer, og at forbrenningsproduktet CO 2 måles eller meng-debestemmes. Mengden ac CC^vil på denne måte gi et uttrykk for mengden av organisk materiale i prøven. Ulemper med sistnevnte metode er at den krever meget dyrbar apparatur, og at selve forbrenningsprosessen vanskeliggjør en fullautomatisk og kontinuerlig analyse. and that the methods require a certain amount of time and a not inconsiderable amount of work in a laboratory. Furthermore, the method has not allowed itself to be automated. Another method, which has recently come into use, consists in a taken sample being subjected to a combustion reaction at higher temperatures, and the combustion product CO 2 being measured or quantified. The quantity ac CC^ will in this way give an expression for the amount of organic material in the sample. Disadvantages of the latter method are that it requires very expensive equipment, and that the combustion process itself makes a fully automatic and continuous analysis difficult.
Det har vært et formål med nærværende oppfinnelse å frem-skaffe en metode hvor ovennevnte ulemper, som er knyttet til kjent teknikk, er eliminert. Det har videre vært et formål å komme frem til en enkel og pålitelig metode, som lar seg automatisere, og som kontinuerlig vil kunne måle og registrere organisk materiale i f.eks. avløpsvann fra en fabrikk, kommunalt avløpssystem e.l. It has been an aim of the present invention to provide a method in which the above-mentioned disadvantages, which are linked to known technology, are eliminated. It has also been an aim to arrive at a simple and reliable method, which can be automated, and which will be able to continuously measure and register organic material in e.g. waste water from a factory, municipal sewage system etc.
De ovenfor nevnte formål er ifølge nærværende oppfinnelse oppnådd med en fremgangsmåte, som i alt vesentlig erkarakterisert vedat et gass- og/ellervæskemedium bringes til kontakt med ozongass, og at den derved dannede karbondioksydgass blir gjenstand for måling og beregninger, slik at innhold av organisk materiale kan beregnes. Øvrige karakteri-stiske trekk ved fremgangsmåten vål fremgå av de etterføl-gende underkrav. According to the present invention, the above-mentioned objects are achieved with a method, which is essentially characterized in that a gas and/or liquid medium is brought into contact with ozone gas, and that the carbon dioxide gas thus formed becomes the subject of measurement and calculations, so that the content of organic material can be calculated. Other characteristic features of the method should be apparent from the subsequent sub-claims.
Fremgangsmåten skal i det følgende illustreres ved hjelp av et eksempel på en utførelsesform av fremgangsmåten og en tegningsfigur. In the following, the method will be illustrated using an example of an embodiment of the method and a drawing.
Væsken, som skal undersøkes, strømmer gjennom rørledningen 1. En magnetisk mengdemåler 2 måler gjennomstrømningsmengden av væsken, og egnede målesignaler tilføres en mikroprosessor 4. Fra rørledningen 1 uttas en prøve gjennom grenrøret 7 og magnetventilen 8 og inn i prøvekammeret 6. Fra en ozonbehol-der 9 tilføres ozongass via en ledning 10 og en magnetventil 11 til prøvekammeret 6, som nå er fylt med væske, som gjen-nomstrømmes av finfordelt ozongass. I prøvekammeret 6 skjer det herved en "kald forbrenning" av organisk materiale, og den dannede CC>2-gass føres til et CC^-måleinstrument 3, som i sin tur sender egnede signaler til mikroprosessoren 5, The liquid to be examined flows through the pipeline 1. A magnetic flow meter 2 measures the flow rate of the liquid, and suitable measurement signals are supplied to a microprocessor 4. From the pipeline 1, a sample is taken through the branch pipe 7 and the solenoid valve 8 and into the sample chamber 6. From an ozone container where 9 ozone gas is supplied via a line 10 and a solenoid valve 11 to the sample chamber 6, which is now filled with liquid, through which finely divided ozone gas flows. In the sample chamber 6, a "cold combustion" of organic material takes place, and the CC>2 gas formed is fed to a CC^ measuring instrument 3, which in turn sends suitable signals to the microprocessor 5,
som bearbeider de innkommende målesignaler, og som på ønsket måte presenterer disse for brukeren. Således vil f.eks. mengdeutslipp av organisk materiale pr. time kunne avleses og registreres. Etter gjennomført analyse av en uttatt og isolert mengde av prøvevæasken ventileres prøvekammeret ved hjelp av en ventilasjonsanordning 12, og prøvekammeret 6 tømmes for prøveløsning gjennom utløpsledning 13 og magnetventil 14. 5 angir utgangssignal-enheten, som kan være for-synt med telefax, alarminstrument etc. Mikroprosessoren 4 styrer og regulerer bl.a. magnetventiler og dermed inter-vallet for analyser. which processes the incoming measurement signals, and which presents these to the user in the desired way. Thus, e.g. quantity emissions of organic material per hour could be read and recorded. After completed analysis of a withdrawn and isolated quantity of the sample liquid, the sample chamber is ventilated using a ventilation device 12, and the sample chamber 6 is emptied of sample solution through outlet line 13 and solenoid valve 14. 5 indicates the output signal unit, which can be equipped with a fax machine, alarm instrument etc. The microprocessor 4 controls and regulates i.a. solenoid valves and thus the interval for analyses.
