    The plant for sewage treatment includes a collective mu 1, into which a pipeline 2 from animals
    The wastewaters to be treated shall be discharged from the premises. The assembly through conduit 3 with pump 4 is in communication with means 5 for the mechanical part 1 of the separation of solid particles, made in the form of a precipitator or classifier. The conveyor 7 is intended for removal of solid particles into the vehicle 6. Under the means for mechanically separating the solid particles, a means 8 is placed for preliminary aeration, made in the form of a tank 9, inside which in the lower part a dispersant 11 is placed on the common hollow shaft IO and located below it is a blade pump 12 with casing 13. Shaft 0 is connected to the shaft of an electric motor 14 fixed to balk 15. in the upper part of tank 9. The upper part I6 of casing 13 of a propeller pump has the shape of a diffuser, and its front end is located at a distance of rum relative to the bottom of the tank 9. In the latter, the submersible pump 17 is installed below the minimum level of the ram. The tank 9 is connected by means of a pipe 18 to a means for mechanically separating solid particles, and the pipework 19 is connected to a flotation device consisting of two stages 20 and 21 with a device 22 coagulation in each of them. In addition, each stage of the flotation device is equipped with a main mixer 23 and having a lower speed with an additional mixer 24 and a chamber 23 common to the stages 20 and 21, equipped with a branching pipe 26 for supplying an air-water mixture, in which a pressure regulator 27 and a mixer are provided 28 reagents. Compressed air required for flotation is generated by compressor 29, which is in communication with chamber 25. The outlet end of conduit 26 is perforated for better distribution of the water / air mixture. Steps 20 and 2 of the flotation device are filled with guiding partitions 30, after which a flotation tank 31 is located, scooping up the floating solids in which the conveyor 32 takes place. Steps 20 and 21 are interconnected by a pipe 33. For loading reagents and polyelectrolyte into the flotation device, they are intended to correspond 22222
    reservoirs 34 and 35 are found. After passing through the second stage 21, the part of the flotation subjected to flotation and the water discharged through the pipeline 36 pumps 5 seconds through the pipeline 37 using recirculating pump 38 to the chamber 25. After the flotation device, a primary sump 39 is installed in the technological sequence,
    10 means 40 for additional aeration, a secondary settler 41 and a unit 42 for final processing of the liquid phase. A pump 44 is designed through the distributor 43 to the means 8 for pre-aeration and the means 40 for additional aeration to feed the deposited activated sludge from the secondary sedimentation tank 41. A pipeline 45, which serves to supply
    20 of activated sludge to the pre-aeration agent, provided with an automatic locking member 46. The open position of the latter corresponds to the on position of the pump 17.
    25 17. To receive sediment from the primary clarifier 39, a tank 47 is intended. Node 42 for final processing of the liquid phase is made in the form of a two-layer biofilter 48 with a bacterial plastic platter 49 and a layer of polystyrene foam in it, with a layer of styrene-coagulimer granules with divinylbenzoic ash containing quaternary and gnome groups. The washing of the tray 49 is carried out with the aid of a device 50 in the form of a pump operating according to the counter-flow principle. The water discharged as a result of the washing is supplied to the start of the cleaning process via conduit 51. The water leaving the unit 42 enters the collection tank 52.

    Wastewater treatment method for; Included in the track dem.
    From the collection team 1, wastewater, in particular manure from livestock breeding premises, through means 5 for mechanically separating solid parts of 50 particles enter tank 9, where they are preliminarily aerated for 5-12 hours using dispersant I1 and paddle pump 12, with In this case, the air-water flow 55 exits through the gap between the lower end of the body 13 and the bottom of the tank 9. In the tank 9, a transition from aiaobic conditions to aerobic occurs. The filling of the tank 9 is related to the time of starting the operation of the pump 4 through the level regulator provided. From the tank 9, waste water is pumped successively by pump 17 to steps 20 and 21 of the flotation device, where it is subjected to flotation simultaneously with coagulation, and these processes are carried out with water-air mixture entering wastewater under pressure of 3-5 kg / cm via pipeline 26 in an amount almost equal to the amount of wastewater treated. During the primary flotation, 60% of the water-air mixture is injected, and during the secondary flotation, 40%. The coagulation is carried out with salts of bivalent or trivalent metals with the addition of polyelectrolyte to the reagents from reservoirs 3 and 35. Then the waste water enters the primary settling tank 39, the means 40 for additional aeration and the secondary settling tank 41. Deposited in the sludge is fed by pump
    44 to a distributor 43, by which it is directed to the container 9 and the container of the means 40 for additional aeration. The minimum dry matter concentration in the activated sludge should be 2-5 g / l. The recycling rate of activated sludge is adjusted to 100-150% of the amount entered.
    wastewater, and 15-25% of the activated sludge is returned to tank 9 for pre-aeration. After the secondary clarifier, the liquid phase enters the unit 42 for final processing,
    which is carried out through a layer of bacteria under the action of gravitational forces in the bacterial plate 49 under anaerobic conditions in its lower part on the side corresponding to
    2/3 of the height from the bottom, and in aerobic conditions in its upper part. The water that is collected as a result of cleaning in the tank 52 can be used for the irrigation without the introduction of diluting water.
