Description

Technical Field

[0001] The invention belongs to the field of textile wastewater treatment, in particular to a textile wastewater recovery, treatment and reuse device for a textile machine. Background Art

[0002] During the weaving process of the textile machine, in order to ensure the smooth shuttle of the yarn, it is necessary to use clean water for continuous spraying to keep the shuttle clean and moist. In this process, some weaving slurry, lubricant, oil and other impurities will be mixed into the water to form wastewater. The water jet loom consumes a lot of water and generates a considerable amount of wastewater. It contains dyes and other coloring substances, which makes the wastewater dark in color and high in chroma. It contains a large amount of suspended matter such as fibers and slurry particles, and has a high content of oily substances. Due to the lubrication requirements of the loom, the wastewater often contains oily substances, high COD content, and high chemical oxygen demand, indicating that the content of organic pollutants is relatively high. The wastewater treatment process of the water jet loom includes pretreatment, biological treatment, physical and chemical treatment, membrane separation technology, deep treatment and reuse, which realizes the resource utilization of wastewater and improves the recycling rate of water resources.

[0003] During pretreatment, the screen pre-filters the wastewater to intercept larger floating objects and suspended solids. However, textile wastewater contains not only large particles of impurities, but also fibers and yarn flocs in cotton yarn. During the screen filtration process, the fibers and yarn flocs cannot be filtered. There are still a large number of fibers and yarn flocs in the wastewater, which may affect the efficiency of wastewater treatment during pretreatment. In addition, due to their light weight, fibers and yarn flocs are not easy to settle in the later sedimentation process, resulting in poor treatment effect or prolonged treatment time, reducing the treatment effect of the treatment equipment on the wastewater.

According to the vortex rotation direction of the wastewater, the scraped impurities rotate with the vortex to the bottom of the fine filter inner cylinder, thereby further improving the water quality of the textile wastewater and facilitating the reuse of the wastewater treated in the filter tank in the textile workshop after treatment.
