Beschreibung der ErfindungDescription of the invention
Das Verfahren dient der Reinigung verschmutzter Wässer von biochemisch abbaubaren Substanzen. Im Gegensatz zu den in der Abwassertechnik üblichen Methoden werden Absetzvorgänge, biochemische Umsetzungen im freien Wasser und an Grenzflächen (wie z.B. beim Belebungsverfahren und Tropfkörperverfahren) sowie die Stabilisation des Schlammes (Gärung, Faulung oder aerobe Prozesse) und die Schlammspeicherung in einer Anlage gleichzeitig und unter wechselseitiger Beeinflussung durchgeführt, so daß das Verfahren als Simultanreinigung zu bezeichnen ist. Je nach Anfangskonzentratxon, Abbauleistungen und gewünschtem Reinigungserfolg kann einstufig oder mehrstufig hintereinander gearbeitet werden. Das Verfahren eignet sich für den Durchlaufbetrieb ebenso wie für Speicherbetrieb (Stapelteiche). Es stellt eine Weiterentwicklung und erhebliche Intensivierung der normalen Teichbehandlung dar, durch die der Flächenbedarf und die Witterungsabhängigkeit verringert werden und mit größeren Teichtiefen gearbeitet werden kann. Das Mittel zur Beherrschung der sich wechselseitig beeinflussenden physikalischen, chemischen und insbesondere biochemischen Vorgänge im Wasser, an den Grenzflächen und im Schlamm ist eine gleichmäßige, gerichtete Strömung im Teich, die die Austauschvorgänge an den Grenzflächen fördert und die das Heranführen der für die Tätigkeit der Organismen nötigen Substanzen sowie den Abtransport der Stoffwechselprodukte besorgt.The process is used to purify polluted water from biochemical degradable substances. In contrast to the usual ones in wastewater technology Methods are sedimentation processes, biochemical conversions in the open air Water and at interfaces (such as in the activated sludge process and trickling filter process) as well as the stabilization of the sludge (fermentation, digestion or aerobic processes) and the sludge storage in one plant at the same time and carried out under mutual influence, so that the process can be referred to as simultaneous cleaning is. Depending on the initial concentration, degradation performance and the desired cleaning success, work can be carried out in one or more stages one after the other will. The process is also suitable for continuous operation as for storage operation (stacking ponds). It represents an advancement and considerable intensification of normal pond treatment, which reduces the space requirement and the weather dependency and can be worked with greater pond depths. The means to master the mutually influencing physical, chemical and especially biochemical processes in the water, at the interfaces and in the mud, a uniform, Directed flow in the pond, which promotes the exchange processes at the interfaces and which brings the necessary for the activity of the Organisms necessary substances as well as the removal of metabolic products concerned.
Die in der Abwassertechnik bisher eingesetzten Belüftungseinrichtungen streben vor allem einen hohen Sauerstoffeintrag an. Sie sind für die Simultanbehandlung brauchbar, erreichen aber keine optimalen Umwälz-The aeration devices previously used in wastewater technology aim above all for a high oxygen input. You are for that Simultaneous treatment usable, but do not achieve optimal circulation

!Leistungen. Die erwünschte langsame Parallel strömung an den Grenzflächen läßt sich mit einem Minimum an Aufwand durch Linienbelüftung erzielen. Zwei als parallele Linien in geringem Abstand voneinander den Teich durchteilende senkrechte Leitwände wirken durch Belüftung an der Sohle als Mammutpumpe mit sehr geringer Hubhöhe, aber extrem hohen Mengenleistungen. Eine waagerechte Fortsetzung der Leiteinrichtung hart über der Sohle dient zur Ausrichtung und Stabilisierung der Strömung. Wenn ausnahmsweise der zur Umwälzung dienende Luftdurchsatz nicht zur Deckung des Sauerstoffbedarfs ausreicht, können mittels feinblasiger Belüftung in der Sohlenströmung, aber außerhalb der Leiteinrichtung unabhängig die benötigten Zusatzmengen an Sauerstoff wirtschaftlich eingetragen werden ο In Oberfläohennähe wird durch den oberen Teil der Leiteinrichtung eine möglichst günstige Umlenkung der Strömung erreicht, die dadurch einen sehr weiten Bereich erfassen kann. Durch Schwimmer vermag sich die obere Leiteinrichtung jederzeit selbsttätig auf den V/asserstand einzustellen. Das Verfahren ist sehr wartungsarm und robust und erfordert geringe Jahreskosten.!Services. The desired slow parallel flow at the interfaces can be achieved with a minimum of effort by linear ventilation. Two vertical guide walls dividing the pond as parallel lines at a short distance from one another act as a mammoth pump with a very low lifting height, but extremely high volume outputs, through ventilation at the bottom. A horizontal continuation of the guide device hard above the floor serves to align and stabilize the flow. If, in exceptional cases, the air throughput used for circulation is not sufficient to cover the oxygen requirement, the required additional amounts of oxygen can be economically introduced by means of fine-bubble aeration in the bottom flow, but independently outside the guiding device Achieved flow, which can thus cover a very wide area. The upper guide device can automatically adjust itself to the water level at any time by means of a float. The process is very low-maintenance and robust and requires low annual costs.
Weitgehende Mineralisation und Eindickung der primären und sekundären Schlämme ermöglichen es, bei dem großen Teichvolumen 10 Jahre und mehr den gesamten Anfall zu speichern und dadurch für die unschädliche Beseitigung wirtschaftliche Großgeräte einzusetzen.Extensive mineralization and thickening of the primary and secondary With a large pond volume, sludge makes it possible to store the entire accumulation for 10 years or more and thus for harmless disposal to use economical large devices.
Das beschriebene Verfahren ist durch das Puffervolumen und die Arbeitsweise unempfindlich gegen extreme quantitative und weitgehend auch gegen qualitative Belastungsstoße. Es eignet sich auch für den Einsatz in überlasteten natürlichen Gewässern ■The method described is insensitive to extreme quantitative and largely also to qualitative impacts due to the buffer volume and the mode of operation. It is also suitable for use in congested natural waters ■
Der wesentliche Fortschritt gegenüber den bisher angewendeten Reinigungsverfahren liegt in der einfachen und billigen Bauweise, in der vorteilhaften Schlammspeicherung, im robusten, wartungsarmen und wirtschaftlichen Betrieb, in der Anpassungsfähigkeit an künftige Entwicklungen und in der Sicherheit, mit der die Gewässer dadurch vor Stoßbelastungen geschützt werden können.The essential advance compared to the previously used cleaning methods lies in the simple and cheap construction, in the advantageous sludge storage, in the robust, low-maintenance and economical Operation, the ability to adapt to future developments and the security with which the waters are protected from shock loads can be protected.
