Abstract

The present invention relates to is water treating process and apparatus for cellulose fiber hydro-entangling process. The water treating apparatus includes a high pressure pump, a police filter set between the high pressure pump and the hydro-entangling machine, a vacuum sucker, an efficient superficial air floating tank, a sand filter, a precise tubular filter and a bag filter. During the production, only bactericide is added to the air floating tank and the sewage tank regularly, and no flocculant and coagulant aid are needed. The present invention has high automation, low cost, water saving and short water treating period.

Description

technical field [0001] The invention relates to a water treatment device and a process thereof, in particular to a spunlace nonwoven water treatment device and a process thereof in textiles. Background technique [0002] Spunlace nonwoven technology uses high-pressure water needles through the micro-holes on the water spray plate to continuously spray the fiber web moving on the screen or drum. The fibers in the fiber are interspersed, entangled, and entangled, so that the fiber web is strengthened. The micropores on the water spray plate are extremely small, and the diameter of the micropores usually ranges from 0.08 to 1.5mm. Therefore, the quality of water has a great influence on the water spray plate. The spunlace nonwoven process uses a lot of water, so it is generally recycled. This has higher requirements on water treatment technology. In terms of circulating water treatment in the spunlace nonwoven process, there is currently an air-floated sand filter integrated...
