Definitions

  • the invention relates to a wastewater treatment device with devices for mechanical pre-treatment, pre-treatment, biological and / or chemical cleaning, post-treatment and sludge treatment.
  • the contaminated wastewater is first pre-cleaned mechanically from coarser dirt particles by means of a catch device and then in a pre-clarifier. This can be followed by biological wastewater treatment using the activated sludge or fixed bed body method in one or more pools. If necessary, chemical flocculants or the like are also added. The flocculated sludge settles in a clarifier before the cleaned water is fed to a receiving water. The sludge settled in the clarifier must then be stabilized, if necessary, disinfected and stacked.
  • Wastewater treatment plants which operate according to this method and are usually built to be stationary have a large space requirement and are economically viable only from a certain amount of wastewater.
  • the wastewater which is produced in small quantities in remote areas, for example agricultural businesses, hotels, campsites or smaller settlements and cannot be supplied to a larger wastewater treatment plant, also requires cleaning.
  • a smaller cleaning device with an aeration tank and a secondary clarifier in a factory-made compact construction has become known. whose use, however, requires additional facilities for pre-cleaning and sludge treatment. A breakdown of nitrogen compounds by biological nitrification is generally not possible with this device. Without sludge treatment, there would also be considerable odor nuisance.
  • the known smaller wastewater treatment devices are also designed for a certain amount of wastewater and are unsuitable if this is subject to larger fluctuations.
  • the invention is based on the object of compactly designing a wastewater treatment device of the generic type for small amounts of wastewater in such a way that it permits the entire process sequence from pre-cleaning to treatment of schiaroma and permits adaptation to the type of contamination and to fluctuating amounts of wastewater.
  • a chamber container is divided by partition walls into a plurality of chambers which are communicatively connected to one another for a successive flow of waste water and in that a device which determines the liquid level is provided.
  • the chamber container can be set up for the cleaning method which is most favorable for the local waste water conditions, in that the chambers required for this are connected in a suitable manner in a communicating manner. This can be done in advance by arranging the communicating device on the workshop side, the waste water purification device being intended for an operating state from the outset. However, if a change in the wastewater conditions, in particular the wastewater quantity, is to be expected, as occurs seasonally in holiday settlements, hotels or the like, the wastewater treatment device can be adapted to the changed operating conditions. if, according to a further feature of the invention, all of the adjacent chambers are connected to one another by closable openings.
  • the biological treatment room can be reduced or enlarged. It is also possible to adapt the chamber used for the preliminary or subsequent clarification. A similar adjustment can also be achieved if the composition of the contamination changes and / or another cleaning method is more suitable.
  • the liquid level can be determined, for example, by assigning a corresponding drain or overflow to the last chamber through which the waste water flows.
  • the closable openings can be designed in various ways.
  • edge elements are provided which can be detachably fastened on the upper edges of the intermediate walls lying in one plane for an optional determination of an overflow path for the waste water.

Abstract

Un dispositif d'épuration de petites quantités d'eaux usées forme une unité compacte portative pourvue de dispositifs de pré-épuration mécanique, de clarification préliminaire et de traitement des boues. A cet effet, un récipient (1) à chambres est subdivisé par des cloisons (4, 5) en une pluralité de chambres (6, 7, 8) qui sont en communication les unes avec les autres de façon à être traversées l'une après l'autre par un courant d'eaux usées. Un écoulement (12) qui détermine le niveau (13) du liquide est agencé dans la dernière chambre (8). La trajectoire d'écoulement du liquide peut être modifiée, étant donné que toutes les chambres adjacentes (6 à 8) sont mutuellement reliées par des orifices fermables (14). En ouvrant ou en fermant ces orifices, on peut déterminer et modifier selon les besoins la trajectoire d'écoulement du liquide.
