WATER TREATMENT PLANT

The field model relates to the field of purification of washing water of filtering facilities and can be used at drinking water supply facilities to create drainage-free water treatment systems

Various schemes of filtering structures are known, including technologists1 v. v some washing water treatment units The washing water of clarifying filters contains a significant amount of contaminants that must be removed before transporting the washing water to the “head of structures or dumping them into the sewer or water runoff

The closest in technical essence to the proposed one is a water treatment plant comprising a source water tank with a booster pump, a clarification filter, a wash water tank with a wash pump, a regenerable filter for treating primary wash water and a secondary wash water treatment unit consisting of sequentially located settling tank and a device for mechanical sludge dewatering. Wash water with clarify; The filter is collected in a wash water tank equipped with a wash / pump that feeds the primary wash water to the regenerated filter to clean the primary wash water. Before suspension, the suspension containing aluminum hydroxide in the wash water is homogenized to a homogeneous suspension by creating a turbulent movement of water using flushing pump. Filtration is completed upon reaching the filtrate.

suspended solids in an amount of 10 mg / l, which is due to the requirements of SNiP with regard to the maximum permissible suspension in water used for washing clarification filters. At the end of the filter cycle, the charge is regenerated, the resulting secondary washing water is sent to settle and the resulting precipitate is subjected to vacuum dehydration / USSR Author's Certificate No. 969293, VOSH 37/00; C02F 1/00, 1982 /

When treating wash water by sedimentation, it takes a long time, which requires large areas of facilities to separate sludge. In this case, the required effect of clarification of the wash water is not always achieved even by increasing the settling time, which does not allow returning water to the “head of structures or dumping it into a reservoir.

The disadvantages of the known installation are environmental pollution during the discharge of sediment into a reservoir or the need for large areas of facilities for separation of sediment, as well as high costs for their own needs.

The technological effect of using the proposed installation is to reduce water losses by creating a drainless water treatment system, as well as to reduce the volume of structures by eliminating the need to devote significant areas for sedimentation tanks and equipment for sludge dewatering while reducing water treatment time.

Installation for water treatment is shown in the drawing.

The installation comprises a source water tank 1 with a boost pump 2, a clarification filter 3, a wash water tank 4 with a wash pump 5, a regenerable cartridge filter of a removable type of primary wash water o, a regenerable or non-regenerable cartridge filter of a removable type of a secondary

rinse water 7 and a waste water tank 8 with a recirculation pump 9, 1 -rauiopripi and pgpe ogvetpitepyugo filto 3

Installation works as follows.

The source water to be treated is supplied to the source water tank 1, from where it is directed by a booster pump 2 for purification to the clarification filter 3, and the water purified on the filter 3 is sent to the consumer. At the end of the filter cycle, the loading of the clarification filter 3 is regenerated by washing it with water supplied from the washing water tank 4 by the washing pump 5. In the process of passing the washing water through the filter 3, it is saturated with impurities washed from the filter loading of the clarification filter 3. The primary washing water is fed into the tank waste water 8, from where it is fed by a recirculation pump 9 for cleaning in a removable cartridge type regenerative filter 6, from where the purified primary wash water flows to the wash water tank 4 and is used to wash the clarification filter 3 and / or to the source water tank 1 to be cleaned in the lighting filter 3. The removable elements of the primary wash water filter cartridge 6 are regenerated by washing with water supplied by the recirculation pump 9 from the waste water tank 8. The secondary wash water after filter 6 is subjected to purification on a regenerative or non-regenerable cartridge filter of a removable type secondary wash water 7, from where the purified secondary wash water is used. pour into the wash water tank 4 and / or the source water tank 1. The spent removable elements of the cartridge filter 7 are replaced with new ones and disposed of or regenerated depending on the material from which they are made.

to reduce the processing time and the area of structures allocated for sedimentation tanks and equipment for sludge dewatering. At the same time, the probability of re-pollution of the environment due to the discharge of contaminated wash water into water bodies is practically excluded.
