Description

Technical Field

[0001] This invention relates to the field of domestic sewage treatment technology, and more specifically, to a sewage overflow filtration and treatment device. Background Technology

[0002] Domestic sewage is wastewater discharged during daily life, mainly originating from residential and public buildings such as homes, government offices, schools, hospitals, shops, public places, and industrial enterprise restrooms. The pollutants in domestic sewage are primarily organic matter (such as proteins, carbohydrates, fats, urea, and ammonia nitrogen) and a large number of pathogenic microorganisms (such as parasite eggs and intestinal infectious viruses). The organic matter in domestic sewage is extremely unstable and easily decomposes, producing a foul odor. Bacteria and pathogens use the organic matter in domestic sewage as nutrients to multiply rapidly, potentially leading to the spread of infectious diseases. Therefore, domestic sewage must be treated before discharge.

[0003] Domestic sewage contains sediment and floating matter. Filtering domestic sewage through overflow can effectively treat the sewage in its initial stage. However, the simple structure may not allow the sewage to be filtered thoroughly enough, and further treatment of sediment is relatively troublesome.

[0004] In view of this, this paper studies and improves the existing problems, and provides a sewage overflow filtration and treatment device, aiming to solve the problem and improve its practical value through this technology. Summary of the Invention

[0031] Working principle:

[0032] Wastewater is introduced into the first chamber 101 through inlet 103. The settled solids in the wastewater settle to the bottom of the upper part of the bottom block 3. Controlling the first motor 8 causes the spiral blade 7 to rotate, which spirally compresses the solids into the filter cylinder 4.

The solids are squeezed out from the gap between the pressure plate 5 and the filter cylinder 4, while the water enters the second chamber 102 through the first water pipe 10. The upper layer of wastewater in the first chamber 101, containing floating objects, flows through the overflow plate 2 into the second chamber 102. In step 2, the filtered water from the filter layer 26 is discharged from the outlet 104. The second motor 14 is controlled to rotate the lead screw 13, which causes the moving plate 12 to drive the scraper 16 to move.

The filter material at the top of the filter layer 26 is rolled into the cleaning shell 17 by the cleaning rollers 18. The water pump 23 is controlled to pump the sewage containing the filter material into the first chamber 101 for circulation treatment.

The bottom block can collect the settled solids at the spiral blades. Controlling the first motor can rotate the spiral blades, which can spirally squeeze the solids into the interior of the filter cylinder. At the same time, the pressure plate squeezes the solids, forcing water from the filter holes into the outer cylinder. The solids are squeezed out from the gap between the pressure plate and the filter cylinder, and the water enters the second chamber through the first water pipe for further treatment. The lower end of the cleaning shell has an arc-shaped structure for accommodating the cleaning rollers, and the cleaning shell... The lower end of the cleaning shell has an elongated hole, and the upper end of the cleaning shell has a round hole communicating with the connecting pipe.
