Abstract

The invention provides a filtering device for textile printing and dyeing and a filtering method thereof. The filtering device for textile printing and dyeing comprises a bleaching box, the top of thebleaching box is fixedly connected with a floating air box through bearing plates, the top of the right side of the floating air box is communicated with an exhaust pipe, and a gas booster pump is arranged at the top of the floating air box. According to the filtering device for textile printing and dyeing and the filtering method thereof provided by the invention, thread residues and broken cloth in textile printing and dyeing wastewater are subjected to primary filtering, so that the device is prevented from being blocked by large suspended matters, and the service life of the device is prolonged; fine suspended solids in textile printing and dyeing wastewater are subjected to secondary cleaning and filtering, and the sewage filtering quality is improved; and large suspended solids suchas thread residues and broken cloth are filtered firstly, then the fine suspended solids are filtered, filtering is carried out in a graded manner, the filtering effect is better, the filtering efficiency is higher, filtering is more thorough, the decoloration efficiency of printing and dyeing wastewater is improved, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the field of textile printing and dyeing wastewater filtering devices, in particular to a filtering device for textile printing and dyeing and a filtering method thereof. Background technique [0002] Textile wastewater is mainly wastewater containing natural impurities, fat, starch and other organic matter produced during raw material cooking, rinsing, bleaching, and sizing. Printing and dyeing wastewater is produced in multiple processes such as washing, printing, and sizing. Organic substances such as starch, cellulose, lignin, and detergent, as well as inorganic substances such as alkali, sulfide, and various salts, are highly polluting. [0003] Currently, existing textile printing and dyeing filtration devices have poor treatment effect on suspended solids inside the sewage and low filtration efficiency in the process of treating printing and dyeing wastewater. Long-term use will cause suspended solids to easily block the...
