Abstract
Description
Zur Überwachung von verfahrenstechnischen Abläufen zum Beispiel in abwassertechnischen An lagen werden zahlreiche Meßwerte aufgenommen und verarbeitet. Die Mindestanforderungen an die verfahrensrelevanten Größen sind in den ATV-Richtlinien (ATV-Abwassertechnische Vereini gung) dargelegt.For monitoring process engineering processes, for example in wastewater engineering numerous measured values are recorded and processed. The minimum requirements the process-relevant variables are in the ATV guidelines (ATV-Abwassertechnische Vereini gung).
Im Zulauf einer Kläranlage sind das z. B. der pH-Wert und der Volumenstrom als kontinuierliche Meßgröße.In the inflow of a wastewater treatment plant z. B. the pH and the volume flow as continuous Measurand.
Im Belebungsbecken einer Kläranlage sind das z. B. der Sauerstoffgehalt, die Temperatur, die Trübung, das Redoxpotential und der Nitratgehalt.In the aeration tank of a sewage treatment plant, these are e.g. B. the oxygen content, the temperature, the Turbidity, the redox potential and the nitrate content.
Im Ablauf werden z. B. pH-Wert, Ablaufmenge, Ammonium-, Nitrat- und Gesamtphosphat-Gehalt gemessen.In the process, for. B. pH, drainage, ammonium, nitrate and total phosphate content measured.
Das geschieht entweder mittels
This happens either by means of
- - einkanaliger Online-Meßgeräte, die vor Ort installiert sein müssen,- single-channel online measuring devices that must be installed on site,
-
- mit Handanalysegeräten
Meßwertaufnahme vor Ort und Aufzeichnung im Protokoll durch daß Personal- with handheld analyzers
Measured value recording on site and recording in the log by the staff - - mit Labormeßgeräten, d. h. die Meßwertaufnahme erfolgt im Labor mit Aufzeichnung und Protokollierung durch daß Personal.- with laboratory measuring instruments, d. H. the measured values are recorded in the laboratory with recording and Logging by personnel.
Die Nachteile der z.Z. angewendeten Meß-, Analyse- und Auswertemethoden sind:
Die Online-Meßverfahren basieren auf einkanaligen Meßgeräten, die kostenintensiv sind. Die
Meßwerte müssen mit SPS, PLS oder z. B. elektronischen Schreibern sicht- und auswertbar ge
macht werden.The disadvantages of the measurement, analysis and evaluation methods currently used are:
The online measuring methods are based on single-channel measuring devices, which are cost-intensive. The measured values must be with PLC, PLS or z. B. electronic writers are made visible and evaluable ge.
Bei den beiden letztgenannten Verfahren ist nur eine punktgenaue Ermittlung der Meßwerte mög lich. Eine weitergehende Verarbeitung wie z. B. Ganglinien erfordern eine Vielzahl von Messun gen und danach die Eingabe per Hand in die Datenerfassungseinrichtung. Das ist arbeits- und kostenintensiv.With the latter two methods, only a precise determination of the measured values is possible Lich. Further processing such. B. Flow lines require a large number of measurements and then manual entry into the data acquisition device. That is work and expensive.
Der Stand der Technik bei Feldmessungen ist, daß mittels Probenehmer Einzel- oder Mischpro ben des zu untersuchenden Mediums genommen werden und anschließend im Labor ausgewertet werden.The prior art for field measurements is that single or mixed pro be taken of the medium to be examined and then evaluated in the laboratory become.
Die Nachteile bei der Feldmeßmethode lassen wie folgt zusammenfassen:
Bei Einzelproben sind nur punktuelle Messungen möglich, einzelne Spitzen können dadurch nicht
erfaßt werden.The disadvantages of the field measurement method can be summarized as follows:
In the case of individual samples, only selective measurements are possible, individual peaks cannot be detected as a result.
Bei Mischproben erfolgt zwangweise eine Mittelwertbildung, so daß eine Ganglinienerfassung erheblich verfälscht wird. Außerdem kann durch die Lagerung der Probe über einen Zeitraum im Behälter eine Verfälschung der Parameter eintreten. In the case of mixed samples, an averaging is compulsory, so that the curve is recorded is significantly falsified. In addition, by storing the sample for a period in the Container a falsification of the parameters.
Die obengenannten Nachteile werden auf erfinderische Weise durch die mobile Meßeinrichtung beseitigt. Das Ausführungsbeispiel ist nachstehend in Funktion und Aufbau beschrieben. Die Meßeinrichtung wird an der Probestelle plaziert. Die zugehörigen Sonden werden in das zu beprobende Medium eingeführt. Danach wird die Meßeinrichtung eingeschaltet, sie arbeitet danach autonom.The above-mentioned disadvantages are solved in an inventive manner by the mobile measuring device eliminated. The embodiment is described below in function and structure. The measuring device is placed at the trial site. The associated probes are added to the sampling medium introduced. Then the measuring device is switched on, it works thereafter autonomous.
Die mobile Meßeinrichtung erfaßt die zu messenden Parameter mit einer festzulegenden frei wählbaren Abtastrate direkt vor Ort und speichert diese Werte online auf dem Datenträger ab. Dadurch werden auch kurzfristige Ereignisse dokumentiert, die mit den o.g. Meßverfahren nur zufällig erkannt werden können.The mobile measuring device detects the parameters to be measured with a freely definable one selectable sampling rate directly on site and saves these values online on the data carrier. This also documents short-term events that are associated with the above Measuring method only can be recognized by chance.
Die Meßeinrichtung besteht aus folgenden Komponenten:

Die Meßeinrichtung kann wahlweise sowohl aus dem Stromnetz der Energieversorger betrieben werden als auch autark über die eingebauten Akkus. Optional ist ein Betrieb mit Solar-/Akku technik möglich.The measuring device can be operated either from the power grid of the energy supplier become self-sufficient as well via the built-in batteries. Operation with solar / battery is optional technology possible.
