The laboratory of our company has conducted a laboratory analysis on the waste water of the printing factory, and the difficulties are that the water quality of the waste water mixed with high-concentration waste liquid fluctuates greatly, the conductivity is high, and the biological treatment is difficult, and the removal of indexes such as amine and AOX is difficult, the processing scale of this printing factory is 1000 T/D, and the diaphragm filter press is recommended. This machine adopts the whole structure of concentrated filter press, with compact structure, small occupied space and relatively large processing capacity, it is applicable to the rapid dewatering treatment of industrial sludge with large amount of mud, and is a preferred model for sludge dewatering in printing and dyeing industry. Part of the emission standard is used back for production, and the rest reaches the discharge standard of water pollutants in textile dyeing and finishing industry.
