In one group of previously known blocked sewage treatment plants, part of the activated sludge sedimented in the secondary sedimentation tank is recirculated to the cleaning chamber by means of a pump system, while aeration is and mixing of sewage takes place in a treatment chamber, another installation dedicated for this purpose. In the second group of known blocked sewage treatment plants, sludge from the secondary settling tank flows by gravity into the treatment chambers, while aeration and mixing of sewage in the treatment chamber is similar to the first group of the above-mentioned known sewage treatment plants. In each of these sewage treatment plants there are at least two separate installations, in including one mixing-aeration and the other recirculation-sludge removal. The object of the present invention is the construction of a combined sewage treatment plant, equipped with a sewage aeration plant, a sludge recirculation plant, a mixing plant for the contents of the mixing chamber and an excess sludge removal plant in which treatment will be carried out in a way that allows the most effective use of the properties of the wastewater treatment process with activated sludge. This objective was achieved by constructing a canopy with an apron located at the bottom of the wall separating the treatment chamber and the secondary sedimentation tank, for a suction pocket connecting through one slit with the secondary sedimentation tank and through the other slit with the purification chamber, and by introducing into this pocket branches of the suction pipeline of the pumping system common to the sludge recirculation installation, the purification chamber contents mixing installation and the excessive waste removal installation The treatment plant according to the invention is particularly advantageous among known blocked sewage treatment plants in that the treatment chamber is a homogeneous, fully mixed reactor.2 134370 An example of a treatment plant according to the invention is shown in the accompanying drawing, in which Fig. 1 shows a vertical longitudinal section and fig. 2 shows a top view. A trapezoidal soil reservoir with slopes and bottom reinforced in the known way, a partition wall 1 is partitioned. The wall 1 divides the tank into a treatment chamber 2 and a secondary settling tank 3. Partition wall 1 with It is equipped in the upper part, from the side of the mixing chamber 2, with an overflow 4 of raw sewage, and in the middle part with holes 5 for the flow of sewage from chamber 2 to the settling tank 3. The settling tank 3 has an overflow 6 receiving the clarified sewage in the sedimentation tank 3. Wall 1 in the bottom Its part is equipped with an apron 7 attached with fasteners 8 detachably to the wall 1. The partition wall 1 in its lower part, from the side of the cleaning chamber 2 has a roof 9 forming an acute angle with the wall 1. The roof 9 at the bottom of the chamber 2 is provided with an apron 10 attached to the visor with fasteners 11 in a removable manner. The slot 12 enables a regulated inflow of activated sludge from the settling tank 3, and the slot 13 enables a regulated inflow of sewage from chamber 2 to the suction pocket 14. The pump unit 15 located in the pump chamber 16 uses a pipeline 17 to draw the mixture of sludge and sewage from the pocket 14 by means of suction branches 18 evenly spaced along the length of the suction pocket 14, and then presses the mixture with a pipeline 19 and branches 20 evenly distributed over the entire width of the treatment chamber 2. The ends of each of the branches 20, on which the jets 21 are installed, are located horizontally at a depth of up to 0.8 m below the surface wastewater in the treatment chamber 2. The treatment process in the treatment plant according to the invention is as follows: the sewage, previously cleaned in one of the known methods, from coarse contamination flows through the overflow 4 into the treatment chamber 2, where it mixes with the oxygenated sewage and active sludge, the result of targeted outflow sewage from the discharge branches 20 towards the escarpment 22 to then flow down it, and then along the bottom of the treatment chamber 2 into the suction pocket 14 as a result of suction by the operating pump unit 15. The aerated and mixed with active sludge wastewater from the treatment chamber 2 gets through the openings 5 to the secondary settling tank 3, sediments are deposited in the secondary settling tank 3, and the clarified sewage through the overflow 6 is drained for further treatment or collection. Part of the sludge from the sedimentation tank 3 is returned to the chamber 2 as a recirculated sludge and aerated in jets 21, in which the recirculated sewage from the treatment chamber 2 is also aerated. To remove the sediment outside the treatment plant, open the valve 24 on the branch 25 with the pump unit 15 in operation. designed to remove excess sludge, and then close the valve 23.
