A treatment system for printing and dyeing sewage

Abstract

The invention discloses a treatment system for printing and dyeing sewage and sludge. The treatment system comprises a blow-off pipeline, a spiral separator, a filter screen device, a garbage treatment device, a first separation pool, a second separation pool and an oil-water separator, wherein the blow-off pipeline is connected to the cavity of the spiral separator; the garbage treatment device comprises a garage transportation belt and a garbage truck; the garbage transportation belt is arranged directly under the outlet end of a spiral discharger arranged on the spiral separator; the garbage truck is arranged at the garbage outlet of the garbage transportation belt. Through secondary separation of the second separation pool and tertiary separation of the oil-water separator, oil and water are thoroughly separated, the separation effect is good, a large number of water sources are saved, solid-phase garbage can be separated and disposed through the arrangement of the spiral separator and the garbage treatment device, a circular rotatable filter screen is arranged, and the filter screen is in multi-point contact with sewage, so that the filtering effect is good, and the service life of the filter mesh is also relatively long.

Description

technical field [0001] The invention relates to a treatment equipment for printing and dyeing sewage, in particular to a treatment system for printing and dyeing sewage. Background technique [0002] With the rapid development of my country's textile printing and dyeing industry, the problem of environmental pollution is becoming more and more serious, and the treatment of printing and dyeing wastewater has attracted great attention from the printing and dyeing industry and the whole society. At present, in the textile fabric setting machine industry, the waste water directly discharged after passing through the oil fume treatment device of the setting machine contains a large amount of oil, which pollutes the environment. If the oil is separated, the waste water can be recycled, and a lot of time can be saved. of water resources. Moreover, the traditional printing and dyeing sewage treatment only has water and oil treatment systems, but solid phase garbage is usually gener...

AI Technical Summary

Problems solved by technology

And the traditional printing and dyeing sewage treatment only has water and oil treatment system, but solid phase garbage is usually produced during printing and dyeing, which cannot be removed

Traditional printing and dyeing equipment is usually equipped with a filter device. However, due to the fixed position of the traditional filter device, the sewage will wash one place of the filter for a long time, resulting in a decline in function and lower work efficiency, and most oil-water treatment uses "oil floating on water" The principle of separation, although the oil floating on the water can be completely removed, but there will still be a lot of water in the removed oil, and there will still be a lot of oil in the remaining water that has not been removed. The effect is not obvious, and more water will still be wasted
