Abstract

Monitoring an aerobic water clarification system by measuring the compressor delivery pressure. The correct supply of air for the aerobic clarification in the final basin of a small three-basin water clarification system is monitored by checking the delivery pressure of the compressor. A pressure switch is fitted in a branch line from the delivery pipe to ensure that there is no escape of air through faulty piping or couplings. Set at about 210 mbar, dependent on the compressor used, it will operate below this value to warn the user of a faulty operation and permit him to take immediate action.

Description

Stand der TechnikState of the art

Bei einer Kleinkläranlage mit Dreikammersystem läuft das Wasser aus der dritten Kammer in einem Nachklärbehälter. Von hier aus wird das Wasser abgeleitet in einem Graben. In diesem Nachklärbehälter wird mit einem Verdichter in bestimmten Zeitabständen durch ein Leitungssystem Luft eingeblasen. Bei diesem Verdichter handelt es sich um einen Linear­ verdichter. Durch die eingeblasene Luft werden die Bakterien mit Sauerstoff versorgt. Um den Verdichter in seiner Funktion zu überprüfen, wurde bis her ein Microschalter im Verdichter eingesetzt, welcher bei einen Membranriss im Verdichter betätigt wird und dieser dann durch eine elektrische Schaltung den Verdichter abschalten ließ.In a small sewage treatment plant with a three-chamber system, the water runs out of the third chamber in a clarifier. From here the water is drained into a ditch. In This clarifier is used with a compressor at specific intervals Air system blown in. This compressor is a linear compressor. The bacteria are supplied with oxygen by the blown-in air. Around To check the function of the compressor, a microswitch has been used in Compressor used, which is actuated in the event of a membrane tear in the compressor and this then had the compressor shut down by an electrical circuit.

Problemproblem

Sollte eine Undichtheit im Leitungssystem (poröse Schläuche, Kupplungen) entstehen so werden die Bakterien nicht mehr ausreichend mit Luft versorgt. Diese Undichtheit wird vom Betreiber zu spät oder meistens erst bei der nächsten Wartung bemerkt. Die Abwasser­ werte verschlechtern sich.If there is a leak in the pipe system (porous hoses, couplings) the bacteria are no longer adequately supplied with air. This leak is caused by the Operator noticed too late or mostly only at the next maintenance. The sewage values deteriorate.

Lösungsolution

Durch eine Überprüfung des Luftdruckes im Leitungssystem während des Einblasens, wird die Dichtheit des Leitungssystems und die Funktion des Verdichters geprüft. Hierzu verwendet man einen Druckschalter, welcher am Leitungssystem angeschlossen ist. Der Druckschalter muß auf den entsprechenden Wert (ca. 210 mbar) eingestellt werden. Dieser Druckschalter stammt von der Firma Fema. Wird Sollwert ereicht gibt der Druckschalter ein elektrisches Signal zur Steuerung. Damit wird der Steuerung mit geteilt das genügend Druck vorhanden ist. Die elektrische Steuerung fragt den Luftdruck dann ab, wenn der Verdichter läuft. Wenn der Luftdruck nicht erreicht wird, wird der Verdichter abgeschaltet und der Betreiber wird durch eine blinkende Störungslampe gewarnt. Diese Störung wird durch die elektrische Schaltung solange gespeichert bis der Betreiber die Quittierungstaste gedrückt hat. Somit kann der Betreiber den Fachmann alarmieren und den Fehler beheben lassen. Dadurch wird ein Verschlechtern der Abwasserwerte vermieden.By checking the air pressure in the pipe system during the blowing in the tightness of the pipe system and the function of the compressor are checked. Used for this a pressure switch, which is connected to the piping system. The pressure switch must be set to the appropriate value (approx. 210 mbar). This pressure switch comes from the Fema company. If the setpoint is reached, the pressure switch gives an electrical one Control signal. This tells the controller that there is enough pressure is. The electrical control system queries the air pressure when the compressor is running. If the air pressure is not reached, the compressor is switched off and the operator becomes warned by a flashing fault lamp. This disturbance is caused by the electrical Circuit saved until the operator has pressed the acknowledgment button. Consequently the operator can alert the specialist and have the error rectified. This will a worsening of the wastewater values avoided.

Zusätzlich kann auf dem Microschalter im Verdichter, welcher beim Membranriss schaltet, verzichtet werden.In addition, on the microswitch in the compressor, which switches when the membrane breaks, to be dispensed with.

Installationinstallation

Die Einblasleitung (Leitungssystem) die vom Verdichter zum Nachklärbecken läuft, muß durchtrennt werden. An welche Stelle man sie durchtrennt ist egal, denn der Einblasdruck im Leitungssystem ist überall gleich. An der Trennstelle montiert man eine Abzweigung (T Stück), welches drei Öffnungen bzw. Anschlüsse besitzen muß. Mit zwei Anschlüsse ver­ bindet man die durchtrennte Einblasleitung und an dem dritten Anschluß schließt man den Druckschalter an (Zeichnung 1).The injection line (line system) that runs from the compressor to the secondary clarifier must be severed. It doesn't matter where you cut them, because the blowing pressure is the same everywhere in the piping system. A junction is installed at the separation point (T piece), which must have three openings or connections. With two connections ver bind the severed injection line and close the third connection Pressure switch on (drawing 1).

Die elektrische Leitung (3 × 1.5 mm2) verlegt man zur Steuereinheit des Verdichters. Um das Signal des Druckschalters auszuwerten, muß man eine elektrische Steuerung bauen. Siehe beigefügten Schaltplan (Zeichnung 2). In diesem Schaltplan ist auch die Intervallsteuerung des Verdichters enthalten.The electrical line (3 × 1.5 mm 2 ) is laid to the control unit of the compressor. To evaluate the signal from the pressure switch, you have to build an electrical control. See attached circuit diagram (drawing 2). This circuit diagram also includes the compressor's interval control.
