Description

Patent application: sewage treatment plant "building" and functional system with associated component set. 3331001

Honor

The subject of the invention is a construction and functional system for the construction and operation of small wastewater treatment plants in the order of four to about one hundred population equivalents and the assigned, specially dimensioned and designed set of components.

¥ It is borrowed, is that the sewage treatment plants from tight, mountable uniform containers that are interchangeable with each other and are made of individual, non-rusting, thin-walled steel sheets or equivalent fabrics, prefabricated cylindrical Shots including top and bottom parts are mounted, exist. ·

The actual function of the sewage treatment plant is given to these tanks by specific installations or conversions, for example for the primary clarification by means of settling process..connected with the digestion and digestion room in a container, but separated by a settling screen, as well for the function of the known trickling filter, but with a secondary clarification room connected to it in a single additional ' Container. The same container, which can be assembled in the same way from the same container elements, can be used as an additional storage unit with a certain further cleaning effect can be designed.

The known sewage treatment plants for the limited use here do not have such a structural and functional system. They build themselves not even on a set of components as shown here. You can therefore not do the technical and economic Achieve advantages of the subject matter of the invention. A particular technical advance with the subject matter of the invention it is also achieved that the container is problem-free, tight, .fast with little installation weight, without any special expertise can be and the cleaning effect is significantly increased by specific fixtures, as well as the preserved decay and revitalization in a trickling filter, similar to large systems in small ones Systems are used.

With the subject matter of the invention, the task set became in detail solved as follows:

The cylindrical wall part (l) with bends (3) is the core component on which the construction and functional system is based and on which
the special built-in components are matched to the individual function. It is preferably made of thin stainless steel sheet.
In the case of particular external loads or to minimize the sheet metal thickness, the gravel is either backfilled on the outside and poured with cement mil or poured in as precast concrete to provide an additional
To obtain pressure ring. (2) The pressure ring can also be a walling or an additional support ring (2b) made of steel profile or similar! be. The individual wall parts (l) become a container with a length that is a multiple of the cylinder height of the part in which
In a tight and force-fit manner, a press ring (-1 over the bends (3) is pulled. The cross-section of this. -Ring adapts to the bends with its shape (4, 4a). a lock (5) with a screw connection. At the bottom, the wall parts assembled in this way are closed with a 'preferably' concave curved bottom part (6). Alternatively, a concrete foundation could be used (6a). The container tube is covered with a similarly shaped, arched lid ( 7) which has an opening (9) with a cover (10). The cover can be reinforced with concrete (8) to take over special loads

For deeper installation positions, deeper than at (13), the cover (9) or the reinforcing concrete (8) is an extension pipe (II), which can also be made of concrete, and is covered with a cover (12) on the same terrain (0. The cover (7) is the support element for the specific equipment of the container depending on the clarification function. Thus, the supply point is created at one point via an arched element (15) can be designed as a rake, passed into the middle of the container, where the separating cylinder (20) with truncated cone screen (21) or just a truncated cone (17) is suspended in such a way that an adjoining partition plate (23), which in turn via a bent or spread plunge plate (2 * 1-), (24a) via screws {2.6) on the cover (7) and on the opposite wall area also with a screw (27) on the cover (7), the Channel (l6) rigid with the separating cylinder r (20 is connected. The cranked upper edge is missing in the area of the separating cylinder (20) which is the drainage channel (22) or the dip plate (24). is opposite. At this point (25) , the liquid phase of the wastewater can flow back into the settling space in the event of an overflow. The separating function of the separating cylinder (20) »(21) or of the truncated cone (17) can be improved by a truncated cone (18) running in the opposite direction, which is preferably screwed to the wall (19).

The bars, of the rake (16), a 'preferred design of the gutter has the special feature that the individual rake bars are welded on the one hand to the separating cylinder (20), on the other hand to each other is connected and taken only at one point in the form of a screw. (27). '- ·

In the same way, it is mounted centrally in the container space a tube inserted with a sieve-like plate (4-3) in the middle summarizes, the discharge pipe (3l) from the lower space (44) which serves as a final clarification room, carries openings below the plate (43) receives (34) for ventilation of the trickling filter space above (42) and further openings (35) through which from the calmed final clarification room (44) the cleaned wastewater flows into the lower area of the pipe space. The pipe space also provides space for a pump line (36 in the event that the purified wastewater over a pump (37) over Pressure pipe (3S) is to be artificially raised in order to rain or to achieve other transport. The pre-treated wastewater flows via the pipe section (l5a), also built into the cover (7) a distribution channel, which preferably consists of at least two channel rings (39) 1 at least, connected with three transverse channels (4o), consists, and They are attached to the cover (7) using hanging screws (4l), adjustable.

A tank (1, 2,3> 4,5,6, 7,) mounted in the same way takes over the function of an additional storage space with certain Cleaning effect, in which a pipe leading to the ground (15 t>), which is also attached to the cover (7) and is guided through the cover, the pre-cleaned wastewater is directed into the floor area the cylindrical space is divided into two by a partition plate (45), which itself a pipe (46) receives in such a way that it is pierced in the upper area and carries the pipe. The stored wastewater that is carried to the ground only reaches a dip pan (48) to the discharge pipe (47), which is also preferably built into the cover surface (7).

Instead of the vertical trickling filter space (42), a flexible pipe in several turns and several levels (50) is wrapped around the container space with settling and digestion function, similar to a package, the inclination of the pipe levels being made dependent on the desired flow gradient of the flow process. The tube package (50) can be protected by a fixed base (53) with a ring band (55)> whereby the cylindrical storage space towards the opening (9) can be covered. The pre-cleaned wastewater flows through this pipe (50) via the discharge pipe (22) • over the length of the entire development of the pipe (50) in order to lead it at its end to an intermediate container in the same assembly design. The pipe spaces can be ventilated more if the ventilation is improved with a standpipe (51). The flexible tube (50) can have a groove wall (56). A trickling filter part in a linear shape (57) can be drawn in over the entire length of the pipe interior, which is wetted by the water flowing through it and the bacterial lawn. The pipe (50) can also have a smooth wall. Instead of the trickling filter part, a longitudinal contact element can be inserted, which consists of a central tension element (58), preferably made of tensile plastic or stainless wire, and of bulky threads (59) or of perforated flaps (60). The longitudinal contact element thus provides space for the bacterial lawn. The trickling filter effect can also be achieved using a horizontal flow-through soil filter, preferably filled with special plants (64). The filter space is tightly sealed at the bottom with special wall parts (62) made of Belch or plastic.The individual butting wall parts are given a bend (66) on the joint surface, which is arched with a press element depends on the desired length of the soil filter. The ends of the floor filter are given a triangular pair of key gels (6 ■ These parts, also made of thin sheet metal or plastic, are connected to the wall parts (62) in the same way as the wall parts are connected to one another Soil filter (63) fed, at the other end (68) diverted to a memory.

The shape of the wall part in vertical section is preferably a triangle, the filter width (b) depending on the desired Installation depth (η.) Is dimensioned.

The pressing element (67b) can also have an arched shape, the ends of the angled portion (66a) of the wall parts (62) are also rolled up.

The entire function and construction system also allows a number of changes in details. Not here in detail treated, described and registered.
