Abstract

The invention can be used mainly in the purification technology of drinking water according to a two-step scheme. The purpose of the invention is to improve the quality of cleaning. The water treatment device comprises a housing divided by vertical partitions into working chambers (RK), in the lower part of which distribution pipes for supplying purified water are installed, and a sludge compaction chamber with transverse sludge drain pipes from the RK connected by vertical pipes with perforated piping (PT), stoked from the ends and installed above the pipe compacted sludge (TO). After the reagents are introduced into water, 10–15% of its total amount is sent directly to the precipitator along the distribution pipeline located between the PT and TO, which allows to intensify the cleaning process by using the process of contact coagulation and reduce the load on the RC. 1 il. o (l

The invention relates to the purification of natural waters and the purification of wastewaters, and can be used primarily for the preliminary purification of water in a drinking water supply.

The purpose of the invention is to improve the quality of cleaning.

The drawing shows a water purification device, a cross-section.

The device comprises a housing 1, divided by two vertical partitions 2 into three chambers, of which two workers 3 and 4 communicate with the sludge compaction chamber 5 through the openings 6 in the partitions 2. The lower part of each chamber is designed as an inverse prism and contains: in chambers 3 and 4 distribution pipes 7 connected to the pipeline for supplying the treated water; In chamber 5, a pipe 8 for tapping compacted sludge and perforated pipe 9, plugged at the ends and connected by nozzles 10 with openings 6. At the top of chambers 3 and 4, grooves 11 are installed, and in chamber 5, pipe 12 intended for collection and disposal clarified water. The openings b on the side of chambers 3 and 4 are protected by peaks 13. In the space between the pipe 8 for the discharge of compacted sludge and the perforated pipe 9, a distribution pipe 14 for the supply of purified water is installed.

The device works as follows.

Purified water with reagents introduced into it is fed into chambers 3 and 4 through distribution pipes 7, and into chamber 5 through pipeline 14. In chambers 3 and 4, the water passing through the layer of suspended sediment formed above the distribution pipes 7 is clarified and collected by gutters 11 and is diverted (if necessary) for further purification. To maintain a layer of suspended sediment in chambers 3 and 4 at a constant level, a continuous transfer of part of the water and sludge from chambers 3 and 4 to chamber 5 is performed. The overflow is performed by maintaining the water level in chamber 5 below the water level in chambers 3 and 4. When Bypassing water and sediment through nozzles 10 enter perforated pipe 9 and further into chamber 5. In the latter, the heaviest part of the sediment is deposited, compacted and continuously or periodically discharged through pipe 8, the other part of the sediment is weighed, creating an additional layer Oh weighted sediment. The overflowed water with sediment coming from pipeline 9, as well as water with added reagents coming from pipeline 14, the passage through an additional layer of suspended sediment, are clarified, collected by pipeline 12 and further mixed with clarified water collected by the grooves 11.

The proposed device allows improving the quality of water purification due to the following factors. At the heart of water treatment

5, in the additional layer of suspended sediment, there is a process of contact coagulation, characterized by intense mutual adhesion of flakes, which differ considerably in their size. In this case, a high speed and completeness of purification of WATER in the sedimentation chamber is achieved. Due to the fact that part of the water being treated (10-15%) is sent directly to the precipitator, the load on the working chambers is reduced. As a result, the rate of upward flow of water in the layer of suspended sediment decreases, which contributes to an increase in the degree of water purification and in the working chambers as well.
