Description

The invention relating to already known devices for sewage treatment using coal. In settling tanks with roll bottoms and chambers equipped with transverse partitions, consists of a device for cleaning waste waters of dyeing factories that differ in their sequential arrangement: 1) a vessel with vertical peregodor1, in which water mixes with coal dust and saturates them with air, 2) a vessel with a conical bottom, where sedimentation of coarse suspended particles occurs, 3) a chute with transverse partitions and 4) settling chambers. |

 In the drawing, FIG. 1 shows a longitudinal section of the device and FIG. 2, top view of the device. |

The proposed device consists of I vessel 1, alternately equipped with non-I vessels reaching the bottom and to the surface of the VOD system with partition walls 8, above which in | there is a funnel 2 on the side for dispensing coal dust; The tube 3 is supplied with air, which enters the vessel 1 through the openings 10 v. of the vessel. Next to this vessel 1, a second vessel 4 is placed with a conical bottom and overflow cone P; the bottom of the vessel 4 is conical and at the top of which a hole 12 is arranged, which is closed by a plug on the long rod 13; The opening is continued by channel 14, OUTLETING Into a well 15. Vessel 4 is connected to the settling chambers 7 by means of a chute 5 equipped with vertical ribs, inclined against the flow} of the cyst, partitions, next to which the chute is connected to it b for dosing coagulum nta. The settling chambers 7 have inclined bottoms, in the lower part of which there are holes 1 16 closed by stoppers equipped with long handles 17; the holes 16 continue to the canals 18 leaving the wells 19. The waste water entering through the tube 9 is mixed in the vessel 1 with the coal dust supplied from the funnel 2 and saturated with air supplied through the pipe 3. In this vessel the absorption of coal dust occurs dissolved substances, including dyes, and oxidation of substances susceptible to oxidation. From the vessel 1 of water through the PLUM 20 and overflow cone 11 enter the vessel 4, where the coarse weighted frequencies precipitate and perb is the stage of water clarification. From here the WATER comes into the trough 5, where coagulum from the vessel b is added to it, and further - in. The backwaters 7, where they are finally released from suspended particles that settle to the bottom, and through pipe 21 descend into the reservoir.
