SU36994A1 - Apparatus for the mechanical treatment of polluted water - Google Patents

Description

The proposed apparatus aims at mechanizing the purification of polluted waters, consisting in the passage of a series of sequential processes to be cleaned by the fluid: mechanical sifting of suspended particles, mechanical separation according to the specific weight of its constituent parts and oxidizing it in a finely sprayed state with pure or ozonized air; For this purpose, a centrifugal filter, a separator and an atomizer, mounted on a common axis, are used.

In FIG. 1 depicts a vertical section of the apparatus along the line ZHZ // FIG. 2; FIG. 2 is a horizontal section of it along the lines AB, VG, DE FIG. one; FIG. 3-vertical section of the filter; FIG. 4-the same separator with a centrifugal atomizer; FIG. 5-axial section of the float valve; FIG. 6, 7, 8, 9-part filter.

The proposed water treatment apparatus consists of a closed vessel / of any shape, inside which a centrifugal filter 2 is placed in an appropriate order for separating particles of heavy water, a separator 3 for isolating impurities lighter than water and for finally discarding the remaining heavier particles a spray-mixer 4 and a whole range of surface oxidizers 5, 6, 7 l. 8.

The apparatus cover, or elsewhere, is fitted with an electric motor W, leading to a rapid rotation of the vertical shaft // on which it is mounted. all rotating parts 2, 5 and.

Through the tube 12, the purification water enters the centrifugal; filter 2 (Figs. 1 and 3), which consists of a conical vessel J4, whose perforated walls are lined with wire or plate drainage 75 covered with fiber bed 16 The lower edge of the latter is attached to the bottom of the vessel by nut 17. When the vessel rotates 14, centrifugal force drops it to the walls along with the water are more heavy impurities, which, delayed by filtering surfaces of the drainage and fiber, rise up and are thrown through the side of the vessel into box 18, the filtered water falls into the tank 19. Regulated valves 20 The required amount of water is passed through horizontal pipe 27 and vertical 22 to separator 5. Here the mixtures are lighter than water, such as fats, etc., collected closer to the center, are thrown upward by centrifugal force through valves 23 into pelvis 24, from where they go down through tube 25 to the outside in barrels. The heavier particles that are still in the water are thrown into the side chambers 26 and from there, in the form of liquid dirt, are pushed as they accumulate through the side openings 27 automatically opening and closing horizontal float valves 28. The latter (Fig. 4 and 5) These are hollow tubes filled with air, which enter the holes 27 with a thin end, and the other end hits the support 29. The valve 28 itself is guided with a fork 30. By screwing and unscrewing the cover 5 / (Fig. 5) the float is shortened or elongation em Whereby varies its specific weight, and opens the opening 27 at longer or shorter intervals. The ejected liquid gets into the basin 32, from where it is discharged through pipes 33.

Cleared of mechanical impurities, the water, lifting up above the cap 34, flows through the openings 35 into the atomizer-mixer 4. After hitting the mesh, perforated or ribbed forest walls 36, the water is divided in advance into thin trickles that fall on the rapidly rotating plate 37 with small teeth 38 along the edges and are sprayed here. In such an atomized state, the water is subjected to the ozonizing action of air, which is driven by an external fan through a turbine 39. The water mixed with air falls into the closed space iH from here passes through a series of oxidizers 5, 6 and 7c plate on top of paths to the oxidizing process by counter current of air. Through the upper and lower openings 44 "45, outside air is forced into the appa | ) At fans, washes the surface of the “filter-oxidizers and exits through the side holes 46.

To purify liquids containing, after the passage of the separator and sprayer, another significant amount of dissolved contaminating organic substances is used over the remaining biological oxidizer in one or more Russes. For the convenience of changing, cleaning, and maintaining, this surface biological oxidizer can be made collapsible in the form of hanging reed or reed mats and pillows connected with non rotting and non rusting yarns. The binding (Fig. B) is made by resin-coated twine or harsh yarns, tinned with metal wire and the like not rusting and not rotting yarns. Reed and cane covered with a bio-absorbent film are highly resistant cleaning material, while at the same time due to their porosity, non-thermal conductivity and plant origin, they are a good basis for favorable development of biological microorganisms. Collected water in the pool before going out passes another filter 8 for the purpose of final clarification.
