(54) Install extensive sedimentation chambers for the treatment of sewage or similar wastewater.

BACKGROUND OF THE INVENTION This invention relates to a sewage treatment plant or similar wastewater, and of the nature of a tank, cistern or similar container, including supply and drainage joints, partitions and sedimentation chambers and access manholes, which tank consists of a cone-shaped container which is placed in a supine position such that a line along its upper wall portion extends substantially horizontally, while its opposite or lower wall portion extends at an angle of a substantial size with a horizontal plane, while the interior of the tank is supported by one or more transverse planes. the longitudinal axis of the tank is separated into at least two chambers.

Various installations of this kind are known, where sewage or similar contaminated wastewater is purified by passing one or more chambers in a tank or cistern system, which chambers are so arranged in relation to inlet and drain that a precipitation occurs. of solids found in the waste water.

Such plants have previously consisted of a buried, cast tank or the cisterns, which are either divided into separate compartments or are connected to one or more similar tanks.

The invention has for its object to provide such a purification plant which can be produced, firstly, by simple, solid and relatively inexpensive structural elements, and secondly provides a good cleaning effect, and where removal of sludge and solid components takes place in a simple manner. manner.

According to the invention, said partitions do not extend all the way to the bottom of the tank, i.e. the lower wall portion of the cone stump so that open passages are formed here for sliding of precipitated sludge, etc., the tank being arranged so that the wastewater is supplied to the bottom-lying chamber, while the purified water is discharged from the upper rabbits and that a access hatch is located at the top of the low-lying chamber, while pipe connections between the chambers are located at the top of the tank.

In the following, the invention is explained with reference to the drawing which shows a side view of a cleaning system according to the invention in section.

The plant according to the invention has a tank 1 which is preferably made of reinforced plastic and has the shape of a cone stub. The tank is buried as shown in the drawing with the upper side substantially horizontal, while the opposite lower side 1 'of the tank is disposed at an angle of a substantial size with a horizontal plane. The wastewater supply is made through a pipe 2, which is placed at the top of the tank's widest end. A drain 3 is located at the top of the narrow end of the tank. The interior of the tank is divided into three chambers I, II and III by means of partitions 4 and 5, which are not brought all the way down to the bottom of the tank, but end some distance above it, so that passages 14 and 15 appear between the chambers.

At the top there are tubular connectors 8 and 9 which connect

Claims (1)

The chambers I, II and III with each other. Each pipe connection consists of two generally vertical pipes 8 'and 8 ", each open at both ends and connected to each other by means of a horizontal pipe piece. One of the vertical pipes 8 * forming inlet pipes is shorter than the other pipe 8 "forming outlet pipe. The outlet pipe 8 "thus extends somewhat deeper into the tank, the same applies to the inlet pipe 7 and the outlet pipe 3. Above the first chamber I a manhole hatch 6 is placed in the tank wall. The cleaning system described works as follows: Sewage water or other contaminated waste liquid is introduced through tube 2, 7. chamber I, where the coarse pollution particles precipitate and collect on the bottom as shown at 10. At the same time, fats found in the wastewater will flow upward and accumulate on the surface as shown at 13. The wastewater then flows through the pipe connection. 3 into chamber II, where there are agents for chemical purification of the water, and these agents are of a known nature and are not indicated in the drawing, and in chamber II a precipitation as shown at 11 occurs due to the chemical additives. the water flows through the pipe connection 9 to the third chamber III, where fine sludge 12 is deposited on the bottom and the purified water leaves through the pipe 3. Sludge which collects in the three chambers will due to of the bottom slope seeps down to the chamber I, which, as mentioned, is provided with a manhole. Through this, the sludge from all chambers can be removed. At the same time as the sludge 10, the fat layer 13 can be removed from the chamber I through the manhole. Patent claims. Wastewater treatment plants or similar wastewater and of the type consisting of a tank, cistern or similar container and including supply and drainage joints, partitions and sedimentation chambers and an access manhole, which tank consists of a keg.
