Printing and dyeing sewage and waste material treatment system

Abstract

The invention provides a printing and dyeing sewage and waste material treatment system. The printing and dyeing sewage and waste material treatment system comprises a depositing device and an oil-water separator, wherein a sewage and waste material feeding hole is formed in the upper left end of the depositing device; a buffering plate is arranged on an inner wall of the depositing device located just below the feeding hole; a filter screen is horizontally arranged in the middle position of the depositing device. According to the printing and dyeing sewage and waste material treatment system, the filter screen is utilized firstly, and solid-phase waste materials and liquid-phase sewage are separated in the depositing device; in a separation process, the deposited waste materials are pushed out of a discharging hole by a material push plate above the filter screen at fixed time under the driving of a hydraulic cylinder; the waste materials fall into a waste material recycling device through a material guide plate, and the filtered sewage passes through a sewage outlet in the bottom of the depositing device and flows into the oil-water separator through a sewage pipe.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing sewage treatment, in particular to a printing and dyeing sewage treatment system. 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. water resources, and the traditional printing and dyeing sewage treatment, only water oil treatment system, but printing and dyeing usually also produces solid pha...

AI Technical Summary

Problems solved by technology

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

[0003] Now there are also printing and dyeing wastewater treatment devices on the market that can simultaneously treat oily water and solid phase pollutants. However, the treatment process of this device is complicated. It needs three treatment processes to treat the printing and dyeing wastewater to dischargeable standards, which is time-consuming and laborious, and not economical and efficient.
