Description

The present invention relates to sewage settling tanks for sewage, consisting of two chambers, open one to the other, expanding in the direction of movement of the waste into them. The septic tanks are equipped with two sludge wells, a movable gate valve regulating the rate of flow of fluid through the septic tank, and ventilation openings at the top.

The proposed settling tank - the rotator is intended for such processing. wastewater, which could enable or directly release the treated water to the soil near the residential premises, or collect pi, in open basins, for the purpose of their further utilization for watering the gardens and for using precipitation as a fertilizer material. For possible achievement of the above tasks, in the proposed sump there is a vertical tube in the inner chamber, which serves for the passage of fluid from the outer chamber {into the inner chamber, surrounded by a conical chamber for collecting gases regulating the direction of the fluid along said tube; h.

In the schematic drawing of FIG. 1 shows the vertical longitudinal section

   .

sump; FIG. 2 - its top view; FIG. 3 is a section on it in FIG. 2, and FIG. 4 - perspective internal view.

The settling settler consists of an outer chamber 1 in which a second inner chamber 2 is located. The chamber 1 is formed by outer walls of rectangular section 3 and inner walls of inner conical section 4

 chamber 2, whereby the cavity of chamber i expands in the direction of water movement, i.e. top down. On the sloping, in the direction to the middle, bottom of the chamber 1 there are four concrete columns 5, on which the inner chamber 2 is located. These columns between themselves under the bottom of the chamber 2 form cross-shaped gaps serving for the passage of fluid into the second inner chamber. The inner chamber 2, as mentioned, is formed by walls 4 located

on the posts 5. From above it is blocked by an iron concrete ring cover b with a manhole 7 and a ladder 8 and is provided with a conical bottom 9 forming the outer walls of the conical chamber 10 (Fig. 1 and 3). For greater stability, in the upper part of the settler between the stenles 3 of the chamber 1 and the walls 4 of the chamber 2 there are concrete lugs 11 in which.

as well as in the upper part of the walls 4, circular holes 12 are located above the possible level of the waste liquid, which serve for the free movement of gases, for incoming air and for gases and air extracted into the exhaust pipe. At the base of the chamber 2, a vertical pipe 13 passing through the throat of the conical bottom 9 is installed; a tube 13 serves to communicate with the chamber 1 and overflow from the last liquid into the chamber 2 and forming a conical chamber 10 with its walls 9 with the lower part of its walls. collecting gases regulating the direction of fluid through pipe 13 to chamber 2. The top of pipe 13 is provided with a conical overlap 14, which serves to more smoothly transfer fluid from chamber 1 to chamber 2. In the outer chamber 1 into which from the receiving chambers through p lattice 20 enters liable working off waste liquids occurs decay and disintegration of the waste liquid, than the resulting precipitates omitting Referring to the bottom chamber are entrained through the apertures 15 and extend in particular Idov wells 22 with a ladder 23 and a manhole 24 (Fig. 3). In the second chamber, decay of the waste liquid occurs, and its strong oxidation by air, rapidly flowing from the filter compartments not shown in the drawing. The sediments collected on the annular bottom of chamber 2 are diverted by nozzles 16 (Fig. 2) to the above-mentioned sludge wells 22. naTpy6ky 17 is retracted from chamber 2 through valve 18 to the filter compartment. The supply air enters the settling tank through the side holes 19 (Fig. 2).

The subject of the patent.

A septic tank for sewage, consisting of two chambers located one inside the other, expanding in the direction of water flow in them, and equipped with two sludge wells, a movable gate valve regulating the rate of flow of liquid through the septic tank, and air vents above, different the fact that the vertical pipe 13, passing inside the chamber 2 and serving to pass the liquid through it: from chamber 1 to chamber 2, is surrounded at the bottom by a conical chamber 10 for collecting gases regulating the direction of the fluid through pipe 13 to the chambers at 2.
