Description

The invention relates to chemical technology and can be used in all areas of the national household for the treatment of natural, domestic, industrial and rainwater wastewater,

The aim of the invention is to increase the capacity of the settling tank, increase the efficiency of water purification, reduce material consumption. labor input during installation.

1 shows a settling tank, a plan view; figure 2 - section aa on fig. 3 - adjusts the 1 "1st weir in cross section.

ny trays 11. Case 1 is equipped with radial re-city to-s 12.

The sump works as follows.

Water through pipeline 3 enters the annular water distribution tray 6 and through adjustable weirs 7 into the clarification chambers 8 with a downward flow. Adjusting the height of the movable weir wall of the weirs ensures the same pressure on all weirs and thus the same hydraulic load on all the clarification chambers with a downward flow. The reflective caps 10 create in the chambers 8 a horizontal surface flow, which contributes to an even distribution of water over the horizontal section of the chamber. When water moves downward, a solid phase is removed from it, which most intensively occurs when the flow is turned through 180 ° into the clarification chambers 9 with the upward flow, where the final water purification takes place. The purified water is collected by trays 11, enters chamber 2 and is discharged through a pipeline. The sediment from the settling tank is removed under hydrostatic pressure through the pipeline 5. The radial partitions 12 are made of a polymer film, which reduces the consumption of materials and simplifies the installation of the settling tank.
