Description

(5) MULTIPLAYED HORIZONTAL DRAWER

one

The invention relates to devices for the purification of natural waters from suspended substances and can be used in the systems of domestic drinking and industrial water supply.

According to the main author. St. The no. Is a multi-colored horizontal sedimentation tank, including a settling part with a plate pack and with cylindrical flocculation chambers, disposed. horizontally under the settling part f 1} from each other.

The disadvantage of the sedimentation tank is a suspension of the suspension at the end of the flocculation chambers, resulting in a reduction in the volume of the flocculation chamber, a reduction in the residence time of water in the flocculation chamber, a reduction in the effect of water clarification in the sump.

The aim of the invention is to increase efficiency.

For this purpose, in a multi-layered horizontal settling tank including a settling part, flocation chambers located horizontally under the settling part, the flocculation chambers are made with longitudinal slots in the bottom part and equipped with sludge collection bunkers.

FIG. 1 shows the proposed settling tank, longitudinal section; in fig. 2 - the same, cross section; in fig. 3, section A-A in FIG. one.

Claims (1)

The sump contains a cylindrical settling part 1, two flocculating chambers 2 with slime-removing longitudinal slots 3, sludge collecting bins k, four tangential nozzles 5, a plate pack 6 installed at an angle of 60 to the horizon, a sludge collecting part 7 with transverse vertical baffles 8, drainage sludge discharge pipe 9, inlet and outlet distribution partitions 10, pipeline 11, two mounting hatches 12, two hatches of flocculation chambers 13, 397 two sediment branch pipes And, two windows 15 and air plunger 16. The sump works leduyuschim way. The natural water to be clarified, along with the reagents, is fed along a pressure line to the flocculation chamber 2, in which the water flow through tangential nozzles 5 receives a rotational-translational motion, due to which the formation of suspended flakes occurs. More heavy chlorine particles fall out in the flocculation chamber and through slots 3 enter the sludge tank. Water containing suspended flakes passes through the windows 15 of the chambers and enters the upper part 1 through the distribution partition 10, where it is freed from suspended particles, passes through the output partition and through the pipeline 11 goes to further purify the water on the filters. The sediment deposited in the chamber 2 slides through the slits into the bunker C, and the sediment precipitated by 0 in the settling zone slides into part 7. The sediment is removed from the bunker 4 continuously or periodically through the branch pipe And, from part 7 the drainage pipe 9 The accumulated air in the sump is automatically removed by means of a vent. 16. Invention Formula Multi-colored horizontal sump according to ed. St. ff, characterized in that, in order to increase the efficiency of the operation, the flocculation chambers are made with longitudinal slots in the lower part and equipped with sludge collection bunkers.
