Sewage circulating treatment system

Abstract

The invention discloses a sewage circulating treatment system, which comprises a bracket, a filter box, a precipitation barrel, a base, an oil-water separation box and a purification box, the top of the bracket is provided with the precipitation barrel and the filter box; the two sides of the precipitation barrel are respectively fixedly provided with a fourth motor and a first slide rail; the output shaft of the fourth motor is fixedly provided with a second threaded rod; the second threaded rod is sleeved with a sleeve; and the sewage circulating treatment system carries out vibration filtration through a filter screen to remove large residues. The residues on the filter screen is extruded out of water by a hot pressing plate, grease is melted, and water utilization rate is improved; then the precipitation box carries out stirring and precipitating to remove a precipitate; the grease is absorbed by an oil absorption plate, oil and water separation is performed; finally, an absorption layer is used for absorption, peculiar smell is removed, a filter layer is used for filtering and decomposing; an ultraviolet lamp is used for sterilizing and disinfecting; and finally, the obtained liquid completely meets the use standard, and can be used again, and a large amount of water resources can be saved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage circulation treatment system. Background technique [0002] With the rapid development of my country's social economy, the construction of new countryside and the continuous advancement of small urbanization, the pollution of rural water environment has become increasingly prominent. In recent years, the discharge of rural sewage in my country has increased at a rate of 15% per year. In my country Among the 2,200 counties and 19,200 towns, the sewage discharge has accounted for more than half of the total sewage discharge in the country, while the current centralized treatment rate of rural sewage in my country is only about 0.5%, and more than 99% of the rural sewage in the country has not been treated in any effective way. The collected treatment is directly discharged to the nearby water body, causing the water quality of the water body to drop significantly, a...

[0008] 4. By setting the oil suction plate to absorb the oil in the water, the oil and water are separated, and at the same time, the V-shaped scraper scrapes off the oil absorbed by the oil suction plate to prevent it from reaching saturation, thereby improving its absorption capacity and effectively overcoming the oil-water separation in the prior art Defects of incompleteness and low oil absorption efficiency
