Abstract

The invention discloses a dyeing wastewater purifying agent. Proper inorganic compound treating agents, organic compound treating agents and microbial inoculants are selected and subjected to optimal combination according to the characteristics of the industrial dyeing wastewater; the microbes generate useful materials and secretions thereof in the growth process to form the matrixes and raw materials for mutual growth; a complex-composition stable-structure wide-function microbial flora with various bacteria is formed through the mutual symbiotic and proliferation relationship; under the multiplex synergistic actions of the inorganic and organic compound treating agents, oxidizers and the like, all the components cooperate in the dyeing wastewater purification process to display the maximum combination advantages; and the dyeing wastewater purifying agent has efficient treatment effect, enables the wastewater to be discharged after reaching the standard, and has the advantages of low cost and obvious economic benefit.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to a purifying agent for printing and dyeing wastewater. Background technique [0002] With the rapid development of the dye industry, the variety and quantity of fuels are increasing day by day, the emergence of a large number of chemical fiber products, and the adoption of new chemical pulp, dyeing chemicals and finishing agents have greatly changed the nature of printing and dyeing wastewater, increasing its The treatment is difficult, and its COD concentration has also increased from the original hundreds of mg / L to 2000-3000 mg / L, so that the COD removal rate of the original biological treatment device has dropped from 70% to about 50%, or even lower. [0003] Printing and dyeing wastewater contains dyes, pastes, additives, oil agents, acids and bases, fiber impurities, sand substances, inorganic salts and other substances. How to find a high-efficiency and low-cost purifying agent f...
