Abstract

The invention provides a treatment device and method of printing and desizing mixed wastewater. The treatment device of the printing and desizing mixed wastewater is characterized by comprising a water collecting regulating tank, a reinforced circulating type efficient anaerobic bioreactor, an aerobic biological contact oxidation tank, a gas-flotation tank, a high-level oxidization tank and an aeration biological filter tank. The treatment device and method disclosed by the invention are especially suitable for treating the high-ammonia-nitrogen high-concentration printing and desizing mixed wastewater generated in printing and desizing processes, a process system disclosed by the invention is adopted to effectively treat the high-concentration high-ammonia-nitrogen wastewater generated by the printing process and high-concentration high-alkaline wastewater generated by the desizing process in printing and dyeing enterprises after the two kinds of wastewater are subjected to flow-dividing and mixing, and also can be combined with a wastewater treatment process for other relatively-low-concentration pollutants in a printing and dying plant to form a complete wastewater treatment system of the enterprise, thereby realizing modifying and upgrading an existing wastewater system.

Description

technical field

[0001] The invention belongs to the field of printing and dyeing wastewater treatment, and is especially suitable for the treatment of high-ammonia nitrogen and high-concentration desizing and printing mixed wastewater produced by printing and desizing processes. The generated high-concentration and high-alkaline wastewater is shunted and mixed with the process system of the present invention to effectively treat it, or combined with other wastewater treatment processes with relatively low concentrations of pollutants in printing and dyeing plants to form a complete wastewater treatment system for the enterprise . Background technique

[0002] The textile printing and dyeing industry is one of my country's traditional pillar industries. With the increase of China's per capita fiber consumption in these years, the output of yarn, cloth clothing and chemical fiber above the domestic scale has leapt to the first place in the world. The prosperity of the textile...
