The present invention provides a device for intensifying the biological processes of sewage treatment in septic tanks.

By constantly increasing wastewater production, especially from small sources, the environment is increasingly becoming increasingly polluted, often with ecological balance. Extensive solutions, such as widening and reconstructing septic tanks, are costly, more soil occupies, and does not solve the problem qualitatively. New systems for biological waste water treatment facilities are being verified and implemented gradually in the world. However, the vast number of already built septic tanks will not be easy to replace. At the same time, septic tanks, built mainly in recent years, represent considerable investments that should be written off prematurely. Their rebuilding requires not only high costs, but also construction capacity and their non-economic use by the necessary dispersion into a large number of small buildings.

These disadvantages are eliminated by a device for the intensification of biological processes in septic tanks according to the invention. The essence of the device is that the device consists of a float tank with a dosing chamber, in which the dosing device with the biozones and the pumping device is stored. The dispensing devices, biodisks and transfer units are mounted on a common shaft. A connection opening is placed between the septum tank and the feeder tank into which a pipe is led, which at the same time is placed at its upper end in the upper part of the lifting device. The function of the device is such that the partially submerged float tank 7 allows the waste water to be dispensed by the metering device 9 from the metering chamber 8. The pumped waste water flows through the biozones 3, where it is cleaned and transferred to the transfer device 10, from where the flange 12 and the connection opening 13 flows into the storage tank 14. When the water discharge level drops below a predetermined limit, the device according to the invention ensures recirculation, the continuity of the biological process is not impaired, so that, with the level drop, the pipe 12 reaches the opposite inclination; drain and return to tank 1 septic tank. Advantages of the device for intensifying biological processes in septic tanks are that in the application of a modular construction system made of plastic elements, a highly efficient device for existing septic structures can be implemented very quickly and at very low cost. The septic tank repair consists of uncovering a part of the ceiling and possibly increasing it according to the dimensions of the coulters. The ceiling must be secured by air, eg through slots. Anchoring the double wires to the wall and sizing the pipe to drain the filtered sewage, these are all the work related to installing the equipment into the septic tank. All of the aforementioned parts of the bioassay and blister device can be manufactured by progressive technology of structural injection molding, so that, apart from the shaft and the drive part, the device can be made of plastics, which guarantees free corrosion resistance and reliability of operation. In addition, biomass is intensively formed on the plastic shaft, thereby accelerating the process. Small-scale floating biological treatment plants allow continuous operation of the plant at uneven waste water flows, while the level variation is irrelevant, and when the wastewater flow is stopped by a drop in water level, the entire plant is simultaneously lowered to ensure a constant recirculation - pipe for the filtered water gets a negative slope and the water returns to the settling tank. Integration of individual structural elements by means of a float makes the device a complete mobile unit, able to apply it to any septic tank. Restricting only the width of the settling tank, but in case of need, this device can be installed in the septic tank two or more.

These devices can be applied in different sizes of bio-diodes, based on generally accepted biological filter design parameters for rotating discs. Another advantage, in addition to speeding up the wastewater treatment process, is the improvement of the process and the possibility of utilizing septic tanks for the connection of other wastewater sources. The method of construction of the device allows for industrial production, which is considerably faster, less costly to manufacture and the size of the built-up area than the construction projects.

In Fig. 1, a complete unit of rotating biodistributing device 4 embedded in a common shaft 5 with the metering device 9 is placed in a septic tank of the domestic sewage sewage system. A pumping device is disposed on the opposite end of the shaft 5 10. The shaft 5 is housed in bearings 6 which are located on the upper edges of the outer walls of the float tank 7. This is made of prefabricated plastic parts. The tank is divided into three cores, the outer chambers being for the metering device 9 and the pumping device 10, in the central chamber there are four biozones 3, in which biodisks 4 are placed. The dosing device chamber does not have a bottom. The transfer device 10 is connected by a pipe 12 via a connecting hole 13 to a connection tank 14.

FIG. 2 shows a device with a side view of the float tank 7 and a pumping device 10 in the direction of the shaft axis 5. FIG. there are schematically shown spacing guides 15 for stabilizing the position of the device in the septic tank and solving the drainage of the purification through the pipe 12 through the connection opening 13. At the same time, an elevated ceiling of the septum 2 above the entire device is shown.
