Abstract

The invention relates to intermittent septic tanks and can be used in the purification of water for domestic and drinking water supply and industrial wastewater containing suspended particles of heavy water. The aim of the invention is to increase the efficiency of the separation of the liquid phases in the settler by improving the hydrodynamic conditions of sedimentation. The sump contains a float connected to a liquid collection chamber and a liquid distribution chamber located under it, a liquid supply pipeline connected to its distribution chamber, and a liquid discharge pipeline connected to its collection chamber. The bottom of the liquid collection chamber is made of filter cloth, the hydraulic resistance of which separates the zone of liquid removal from the sedimentation zone. The chambers are provided with trays, on the bottom of which the nozzles of the respective pipelines are connected, connected by bellows. Filter fabric has a significant hydraulic resistance, evenly distributed over the collection area of the clarified liquid. This allows the hydraulic connection between the liquid in the collection chamber and underneath to be reduced and thus reduce the horizontal components of the movement of the liquid in the sump, and hence the sedimentation of the sediment. 3 il.

Description

The invention relates to intermittent septic tanks and can be used in the purification of water for domestic and drinking water supplies and industrial wastewater containing suspended particles of heavy water.

The aim of the invention is to increase efficiency. separating the phases of the liquid in the sump by improving the hydrodynamic conditions of the settling.

FIG. 1 shows the sump, general view; in fig. 2 - sump plan; in fig. 3 shows section A-A in FIG. 2

The sump consists of a rectangular section body 1, in which a float 2 is installed with a gap, the buoyancy of which is provided by section 3. The liquid distribution chamber 4 is made in the form of parallel perforated pipes 5 fixed on opposite sections 3 of the float 2. On pipes 5 a tray 6 is fixed having a hydraulic connection with the chamber 4 through the openings 7 in each pipe 5.

A fluid supply pipe 8 with a shut-off device 9 has a pipe 10, one end of which is connected by an elastic bellows insert 11 to the pipeline, and the other end rests on the bottom of the tray 6.

The liquid collection chamber 12, formed by sections 3 of the float 2, has a bottom 13 of filter cloth, chlorine. The chamber 12 is provided with a tray 14 fixed to the pipes 5, inside of which the tray 6 of the liquid distribution chamber 4 is located. The filter cloth is fixed on the walls of the sections 3 of the float 2, the side walls

tray 14 and the projectile 15, attached to the pipe 5 and prevent swelling of the fabric during movement of the float 2 down. As can be seen from the drawing (Fig. 1), the tray 6 is above the tray 14.

The pipe 16 of the drain with shut-off device 17 has a pipe 18, one end of which is connected by an elastic insert-bellows 19 with a pipeline. On the other hand, the pipe pipe 18 protrudes into the tray 14. When the float is lowered 2, the ends of the pipes 20, 21 due to the syringe 19 are also lowered and simultaneously move along the tray 14.

The removal of the clarified liquid is performed to a predetermined level in the housing 1 or until the float 2 reaches the boundary of the clarified part of the liquid with its part containing solid particles.

At the end of the drainage of the clarified liquid inlet 16, the locking device 17 is closed for two branch pipes - 10, ka 20, 21, each of which is located, the locking device 9 opens and the light between the side walls of the trays 6, 14 and the liquid is supplied to the sump, rests on the bottom of the tray 14.

A sump, comprising a housing, a float connected to a chamber for collecting liquid turbulence of flow, while 25 and a distributable liquid located beneath it distract the minimization of the fluid, the liquid supply pipeline. When the float 2 is lifted, the bone end connected to the chamber of the diffuser-pipe 10 of the pipeline 8 by force and the pipe for drainage of the background 11 also rises and at the same time is single with the camera of its collection, which differs - moves along the tray 6. that, in order to increase the effective distribution of the incoming liquid, it also reduces the separation of the liquid in the liquid from the liquid in the collecting chamber and the distribution of the liquid into the water, i.e. are supplied with trays, pipelines under water and drainage are supplied with bellows and nozzles placed respectively in the tray of the distribution chamber. The porous device 9 is closed and through 35 and in the tray of the liquid collection chamber, with the specified distribution time, the locking device 17 is located in the pipe 16 inside the tray , collecting the liquid and its upper part, a vacuum is created and the clarified liquid is placed above the upper edge; the bone is retracted from the log 14. In this collection tray, the branch pipes of the retraction pipe, the float 2 is lowered and luminous water, liquid d are located between the side ones, filtering through chlorine and thereby the walls of the trays, and the bottom of the collection chamber is liquid from finely dispersed suspensions; the side is made of filter cloth.

In the upper position, the float 2 is inserted into the tray 14. When the float 2 is lowered, the ends of the nozzles 20, 21 due to the sylph 19 also lower and simultaneously move along the tray 14.

The removal of the clarified liquid is performed to a predetermined level in the housing 1 or until the float 2 reaches the boundary of the clarified part of the liquid with its part containing solid particles.

At the end of the drainage of the clarified liquid, the locking device 17 closes, the locking device 9 opens and the clarified liquid is supplied to the sump. When the clarified liquid is drained from
