Description
Beschreibung Die vorliegende Erfindung betrifft ein Verfahren und eine Vorrichtung zur kontinuierlichen Trennung eines Schlamm-Wasser-Gemisches in Schlamm und Wasser. Description The present invention relates to a method and a device for the continuous separation of a sludge-water mixture into Mud and water.
Hierbei ist die behandelte bzw. geklärte ablaufende Wasser~ menge liner gleichbleibend, wobei die Zulaufmenge zu dem Behandlungsr@um außerhalb der Kläreinrichtung beliebig sein kann.This is the treated or clarified amount of water running off liner constant, with the inflow amount to the treatment room outside the Clarifying device can be any.
Nach dem derzeitigen Stand der Teohnik ist die Kläreinrichtung zur Vor- und/oder Zeischen- und/oder Nachklärung vorzugsweise kommunizierend mit der vorgeschalteten Behandlungseinrichtung verbunden.According to the current status of Teohnik, the clarification facility is for Pre- and / or Zeischen- and / or post-clarification, preferably communicating with the connected upstream treatment facility.
Das hat zur Folge, daß die einem Klärsystem (z.B. mechanische Nachklärbeoken, Vorreinigung, Belebungsbecken) zulaufende Wassermenge der ablaufenden Wassermenge gleich ist.This has the consequence that a clarification system (e.g. mechanical secondary clarification tokens, Pre-cleaning, aeration tank) inflowing water volume of the draining water volume is equal to.
Damit sind alle Bemessungsgrö#en (z.B. Beckeninhalte, Oberflächenbeschichtung, Oberflächenbelastung) zur ein Klärsystem auf eine maximale Zulaufmenge auszulegen (z.B. ###).This means that all dimensioning values (e.g. basin contents, surface coating, Surface load) to design a sewage system for a maximum inflow quantity (e.g. ###).
Wird diese maximale Zulaufmenge über lange leiten (nachts) nicht erreicht, sind diese Baugrö#en eigentlich nicht erforderlich und damit unrentabel0 Bei Mischkanalisation wird die mechanisch und biologisch zu reinigende Abwassermenge gesetzlich begrenst, um die Investitionskosten der Kläranlagen in wirtschaftlichen Grenzen zu halten, d.h. alle durch Regenwasser verdünnter Abwasser darf über einen bestimmten Zulaufwert (z.B. 5 TWA) direkt dem Vorfluter (Baoh oder Flu#) zugeleitet werdens ein Teil der nun dem Klärwerk zulaufenden Abwassermenge wird nach mechanischer Vorreinigung biologisch gereinigt (z.B0 2 TWA).If this maximum inflow quantity is not reached over a long period of time (at night), these sizes are actually not required and therefore unprofitable0 In the case of mixed sewer systems, the amount of wastewater to be cleaned mechanically and biologically legally limited to the investment costs of the wastewater treatment plants in economic To keep limits, i.e. all wastewater diluted by rainwater may exceed one certain inflow value (e.g. 5 TWA) directly to the receiving water (Baoh or Flu #) part of the wastewater that is now flowing into the sewage treatment plant is mechanical Pre-cleaning biologically cleaned (e.g. 02 TWA).
Durch diese Ma#nahme werden die Vorfluter bei Regen durch unbehandeltes (zOB. Wassermenge über 5 TWA) oder nur mechanisch gereinigtes Abwasser (z0B. 3 TWA) verschmutzt. With this measure, the receiving waters are replaced by untreated water when it rains (zOB. water quantity over 5 TWA) or only mechanically treated wastewater (z0B. 3 TWA) dirty.
Das erfindungsgemäße Verfahren ermöglicht es, diese Nachteile weitgehend zu beseitigen. So kann zeBX durch eine Nachkläreinrichtung, die auf einem Belebungsbecken schwimmt, eine gleichbleibende gering Menge gereinigten Abwassers kontinuierlich abgezogen werden (z.B. ###) und nur das Belebungsbecken bedarf einer Bemessungsgrö#e, die den Spitzenzuläufen angepaßt ist (z0B. TWA).The method according to the invention makes it possible to largely remedy these disadvantages to eliminate. For example, zeBX can use a secondary clarification device on an activated sludge tank floats, a constant small amount of treated wastewater continuously can be deducted (e.g. ###) and only the aeration tank requires a dimension, which is adapted to the peak inlets (e.g. TWA).
Für Mischkanalisation kann nach dem erfindungsgemä#en Verfahren die Wassermenge, die biologisch gereinigt werden kann, wesentlich größer sein.For mixed sewerage, according to the method according to the invention, the The amount of water that can be biologically cleaned can be much larger.
Hierfür wird z.B. die schwimmende Nachkäreinrichtung auf ein Jahreszuflu#mittel ausgelegt (Mittelwert zwischen Regenwetter-und Trockenwetterzufluß), während das Belebungsbecken ffir den maximalen Zufluß ausgelegt wird.For this purpose, e.g. the floating post-processing facility is based on an annual inflow designed (mean value between rainy weather and dry weather influx), while the Aeration tank for the maximum inflow is designed.
Durch diese Naßnahie ergeben sich unter Beibehaltung der bisher gültigen gesetzlichen Bestimmungen kleinere Baueinheiten zu geringeren Investitionskosten oder die biologische Reinigung einer größeren Abwassermenge bei wirtschaftlich vertretbaren Kosten.This Naßnahie results while maintaining the previously valid legal regulations smaller units at lower investment costs or the biological purification of a larger amount of wastewater when it is economically feasible Costs.
Der gleiche Effekt kann erfindungsgemäß erzielt werden, wenn man die Kläreinrichtung zur Vor -und/oder Zwischen-und/oder Nachklärung z.B. nicht schwimmend, sondern mit einer Vorrichtung dem wechselnden Wasserstand des umgebenden Wassers anpaßt.The same effect can be achieved according to the invention if the Clarification device for preliminary and / or intermediate and / or secondary clarification, e.g. not floating, but with a device the changing water level of the surrounding water adapts.
