Definitions

  • the invention relates to a container for flocculating waste water with an inlet connection, an outlet pipe and at least one connection connection for the addition of treatment agents, the inside of the container being divided into several labyrinth-like chambers by partially overlapping partition walls.
  • Such a container is known from DE-A-2 383 887, in which labyrinth-like chambers are provided which run in the horizontal direction. This results in a flow in a horizontal plane along a labyrinthine path.
  • Several of these webs are provided, which are arranged one above the other, the end of each web being connected to the beginning of the next higher web, so that the flow of the waste water is increased at the level when it leaves the container.
  • the flow essentially takes place in horizontal planes.
  • the known container has a connecting piece for the addition of treatment agents in order to initiate flocculation of the waste water in the container. About every second chamber of the container is provided with obstacles in order to achieve the most turbulent flow possible, which should promote the flocculation process.
  • a container is also known, in which the inlet nozzle merges into an inlet channel, which is designed as a tube projecting into the interior of the container.
  • the latter has the task of bringing the liquid flowing in from the inlet connection as close as possible into the bottom region of the container, specifically in the region of a connection connection there for the addition of the flocculant.
  • the area of application of such a container is limited in that complex processing fluids cannot be adequately treated.
  • the invention is therefore based on the object of creating a container of the type mentioned at the outset, which brings about an improved treatment of waste water in such a way that preparation is possible in the case of chemically complex processing liquids.
  • the container is designed as the flocculating of the vibrating wastewater resulting from vibratory vibratory grinding or the like with vertical dividing walls and that the connecting piece serving to introduce flocculants is located in the beginning of a chamber following another chamber in the upper region of the container and the flocculation zone adjoining it extends over at least two chambers, an emptying opening being provided in the bottom of the container in the region of the transition cross section of the two chambers connected in series. Due to the design as a vibration container, the flocculation is forced enormously, which considerably increases the efficiency of the container according to the invention.
  • the additional vibration creates a relative movement of the individual flakes with respect to one another, which decisively promotes growth.
  • the arrangement of the connecting piece for introducing flocculating agents in the initial area of a further chamber following a chamber in connection with the position of the connecting piece in the upper area of the container and the adjoining flocculating zone which extends over at least two chambers leads to the formation of a flow reversal point.
  • the waste water inoculated with flocculants is first directed downwards, then via the reversal point and then upwards. A superimposition effect due to the vibrations due to the vibration of the container and the flow deflection occurs, which considerably accelerates the flocculation.
  • This effect occurs in that the individual flocculated particles vibrate in a very specific vibration level due to the predetermined vibration initiation. This level of vibration is at a certain angle to the direction of flow of the liquid to be treated. If the liquid is now deflected at the reversal point, the vibration plane and flow direction change their position relative to one another, so that particularly intensive particle movements and thus particularly frequent and violent contact with the flocculation substances occur. Braking and acceleration processes of the particles occur, whereby the formation of small flakes is required and smaller flakes grow into larger ones. Furthermore, smaller flakes are touched caught with larger flakes, so that overall a lively flocculation process takes place. Smaller flakes pass the reversal point with the liquid flow and are carried out of the drain pipe for filtering or the like.
  • the short dwell time follows from the fact that the vibrating bed does not allow the flakes to be firmly joined together, but instead repeatedly repels flakes due to the vibration movement, which flakes then leave the container according to the invention through the outlet nozzle.
  • the emptying opening arranged in the bottom of the tank in the region of the transition cross section of the two chambers connected one behind the other can be used to remove the sedimentation.
  • the sedimentation can easily escape by simply opening the emptying opening, since the vibrations of the container do not allow the formation of a solid bed of sludge.
  • the exit of the individual particles can be considerably supported by opening the emptying opening during the vibration process so that the sedimentations are "vibrated out”.
  • the inlet connection continues into an inlet channel, which extends into the interior of the container and is formed by the first of the partition walls, which is assigned to the outlet pipe in a siphon-like manner, and that, based on the direction of flow through the container, a first connection socket for introduction of flocculation preparation chemicals is arranged in the initial area of the inlet channel. This extends the treatment distance by the length of the inlet channel.
  • a second connection piece for introducing flocculation preparation chemicals is provided near the bottom of the container, which is located at the level of the transition cross-section left by the first partition to the first chamber following the inlet channel.
  • the first chamber following through the inlet channel lies.
  • the liquid flowing into the container through the inlet channel is exposed to a chemical process as it passes through the first connecting piece, by means of which a flocculation preparation chemical, such as e.g. Sodium hydroxide solution is added.
  • a flocculation preparation chemical such as e.g. Sodium hydroxide solution is added.
  • the liquid to be treated is mixed with the flocculation preparation chemical.
  • this pretreated liquid reaches the area of the subsequent connection piece, it is enriched with another flocculation preparation chemical.
  • it can be an electrolyte solution, for example, which brings the pH value into the range of 7.
  • the flocculant is then added in the initial region of the flow direction of the downstream chamber through the last connecting piece there. The final preparation of the liquid now takes place.
  • the arrangement can be such that a closable drainage connection is provided in the floor area below the transition cross section left free by the first partition. Coarse grains or grit-like abrasive grit can be drained through the open drain connection.
  • the container 1 is fixedly connected to the liquid drain 3 of a helical vibration scrubbing container 4 of a conventional vibratory vibratory grinder according to FIGS. 1-3 via an inlet connection 2.
  • the vibrating scrubber 4 could be any other have a known shape.
  • the processing liquid flowing in via a hose 5 and an annular shower 6 can therefore flow continuously into the container.
  • the container 1 participates in the vibrations of the vibration scrubbing container 4.
  • the container 1 is box-shaped. In the case of a vibrating scrubbing container 4 with a capacity of approximately 600 liters, its capacity is approximately 1 liter. Expressed in numbers, this means that the container has a width x of 55 mm and a length y of 120 mm with a height z of 150 mm.
  • the individual container side walls bear the reference numbers 7, 8, 9, 10, to which the container base 11 and the container lid 12 are assigned.
  • the inlet connector 2 extends from the container lid 12 near the narrow container side wall 7. In opposite position to the inlet connection 2 extends an outlet connection 14 connected to the tank bottom 11, which can be closed by means of a spring-loaded ball 15.
  • the interior of the container is divided into three chambers I, II and III arranged downstream of the inlet channel 19 by three dividing walls 16, 17, 18 which overlap in the vertical direction and which are parallel to the container side walls 7 and 9.
  • the partition 16 starts directly on the container lid 12 so that the wastewater coming from the vibrating scrubbing tank flows through the passage cross section 20 of the container lid 12 into the inlet channel 19.
  • the partition wall 18 adjacent to the container side wall 9 also extends from the container lid 12, while the partition wall 17 lying between the partition walls 16 and 18 is attached to the container base 11.
  • the length of the approximately mutually parallel partition walls is shorter than the height z of the container, so that between the inlet channel 19 and the first chamber 1, a transition cross-section 21, between the first chamber I and the second chamber II, a transition cross-section 22 and between the second chamber II and the third chamber III have a transition cross section 23.
  • the inlet channel 19 and the subsequent chambers 1, II and III are arranged like a labyrinth to each other.
  • the inlet channel 19 has a connecting piece 24 fastened to the container side wall 7, through which a preparation chemical can flow.
  • a further connecting piece 25 is fastened to this container side wall 7 in the lower region, specifically at the level of the transition cross-section 21 to the first chamber I left by the first partition wall 16.
  • the connecting piece 25 is thus located in the initial region of the flow through the inlet channel 19 downstream chamber I.
  • This connecting piece 25 is used to add a further flocculation preparation chemical, for example an electrolyte solution, which brings the pH of the liquid coming from the inlet channel 19 into the range of 7.
  • the partition 16 extends approximately on the center line of the inlet connection 2 and the outlet connection 14.
  • the connecting piece 26 for adding the flocculant is arranged in the upper region of the container 1, and this extends in the region between the two partition walls 17, 18 in the transition cross-section 22 between the first chamber I and the second chamber 11.
  • the second chamber II in Initial area of the flow on this connector 26.
  • the flocculation zone adjoining this connecting piece 26 accordingly extends over the chamber II and the chamber 111.
  • the container lid 12 is provided with a ventilation opening 30 above the flocking chamber II.
  • the wastewater coming out of the inlet connection 2 is treated by the container 1, which participates in the vibrations of the vibrating scrubbing container, in the inlet channel 19 and in the adjoining chambers I, 11, III, with the addition of suitable chemicals, so that the liquid leaving the outlet pipe 27 is prepared for the sewer network.
  • the container 1 which participates in the vibrations of the vibrating scrubbing container, in the inlet channel 19 and in the adjoining chambers I, 11, III, with the addition of suitable chemicals, so that the liquid leaving the outlet pipe 27 is prepared for the sewer network.
  • a multi-chamber process can be used. There is no risk of liquid shifting or mixing back from one chamber to the other. The flow is not adversely affected by the vibrations.
