Description

The invention relates to devices intended for the purification of natural and waste waters from mechanical impurities, and can be used in the technique of purifying water on municipal, industrial, agricultural water supply systems and sewage treatment plants.

The purpose of the invention is to improve the hydrodynamic conditions of fluid distribution.

FIG. 1 shows the catchment system of the settler, a longitudinal section; in fig. 2 is a view A of FIG. one; in fig. 3 is a view B in FIG. one.

The catchment basin of the sump contains a vertical overflow wall 1, made with rectangular windows 2 for outputting the clarified liquid, a partition 3, installed in front of the overflow wall 1 with the possibility of vertical movement and made with a rectangular perforation 4, with an upwardly increasing degree of perforation, guiding peaks 5 attached to the lower edge of the perforation holes 4 with the ability to change the angle of inclination using the adjusting mechanism 6, lifting device 7, collecting chamber 8, retraction The clarified water pipeline 9, the pipeline 10 for emptying the collecting chamber.

The device works as follows.

The flow of clarified water moves horizontally in the sump and fits into the sump drainage system, including the overflow wall 1 and the partition 3.

Water passes through the holes 4 in the partition 3 and the window 2 in the wall 1, the flow

In id

which depends on the total area of the through holes. The area is formed by the overlapping of holes in the wall 1 and the movable partition 3, in which the degree of perforation increases from bottom to top.

Moving the partition 3 with a change in the angle of inclination of the peaks 5 allows the total area of the catchment section of the catchment system to change and thereby change the velocity of the fluid in the sump and its direction at the overflow wall 1. When the peaks are located 5, the suspension components horizontally decrease, when they rise to a certain angle, the water flow from the surface layers increases, where it has a higher degree of purification. Since a large area of water collection is used, the magnitude of the inertial effect and, consequently, the transverse circulation of water in the sump reduces to

0 minimum. The change in height of the total area of the perforations is accomplished by moving the partition 3 with the aid of a lifting device 7. From the collecting chamber 8, the clarified water is discharged by the pipeline 9. The accumulated sediment is discharged and the collecting chamber 8 is emptied.

The use of the proposed catchment system by preventing the formation of stagnant zones and improving the hydraulic conditions of the septic tanks allows an increase in the volumetric utilization rate by 30–40% and, accordingly, an increase in the efficiency of water clarification or an increase in the load by 30–40% on the structure.
