Abstract

The invention discloses a textile wastewater treatment agent and a preparation method and application thereof. The textile wastewater treatment agent is composed of, by weight, 8-15 parts of acrylic acid, 5-12 parts of tetrabutyl urea, 12-20 parts of longan shell, 25-33 parts of kaolin and 1-5 parts of diphenylmethane diisocyanate. The preparation method includes: smashing the longan shell, using a prepared acrylic acid solution for soaking, and thermally stirring to obtain a longan shell material; grinding kaolin, adding tetrabutyl urea, stirring, adding the longan shell material, stirring, adding diphenylmethane diisocyanate, stirring, and performing microwave treatment, high-temperature calcining and cooling to room temperature to obtain. The treatment agent is used for treating textile printing and dyeing wastewater and is quick in condensation, good in decoloring effect, high in activity, free of secondary pollution, low in dosage, convenient to use, suitable for the textile wastewater having big change in water quality and good in acid-resistant heat-resistant performance. The treatment agent is extensive in raw material source, low in production cost and free of corrosion of and damage to equipment, and the preparation method is simple in process, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a textile wastewater treatment agent and its preparation method and application. Background technique [0002] Textile wastewater is mainly wastewater containing organic matter such as natural impurities, fat, and starch produced during the cooking, rinsing, bleaching, and sizing of raw materials. Printing and dyeing wastewater is produced in multiple processes such as washing and dyeing, printing, and sizing. It contains a large amount of organic matter such as dyes, starch, cellulose, lignin, and detergent, as well as inorganic matter such as alkali, sulfide, and various salts. very strong. Wastewater is characterized by high concentration of organic matter, complex composition, deep and changeable color, large pH changes, and large changes in water quantity and quality. It is a difficult-to-treat industrial wastewater. With the development of chemical fiber fabrics,...
