Introduction to the industrialization achievements of high-efficiency Decolorizing Flocculant

content introduction: the production technology of this product overcomes the lack of explosion polymerization caused by sudden temperature rise in the previous process, makes the current production process more reasonable and reliable, and the product quality more stable, and has obtained the Chinese invention special

high efficiency Decolorizing Flocculant cationic, organic polymer. Its cationic tensile strength, constant elongation, constant elongation force value and yield strength subgroups can interact chemically and physically with anionic genes (such as sulfonic acid group and carboxylic acid group) and active groups (such as cyanuric chloride)

of some dyes and intermediates, so as to destabilize dye molecules and separate them from water, achieve decolorization and reduce C

OD. Efficient Decolorizing Flocculant is easy to use and has outstanding effect. The decolorization effect of this product is better than or equal to that of its samples through parallel comparison test with similar samples in the United States and Japan. This product has reached the advanced level of similar foreign products, and the industrialized product is still the first in China

product technical indicators: the appearance is light color, viscous liquid, solid content> 50%, pH value (30%

aqueous solution) is 3-6

this product is suitable for the treatment of reactive, acidic, direct dyes in the dye and printing and dyeing industry and some intermediates with high concentration

and high chromaticity production process wastewater

Kunshan Huacheng weaving and dyeing Co., Ltd. discharges 5000 cubic meters of printing and dyeing wastewater every day. Sodium hypochlorite

was originally used for decolorization, but the decolorization effect is not ideal, especially the decolorization of red reactive dyes is difficult to solve, and the sodium hypochlorite method has problems such as unstable effective chlorine content, serious corrosion of equipment and pipelines, and high residual chlorine in the discharged water after treatment. The decolorization problem can be solved by using high-efficiency Decolorizing Flocculant alone. The decolorization rate can reach 95.7

%, and the removal rate of COD can reach 70.5%. Considering the user's original biochemical treatment equipment and reducing the cost of operation, decolorizer and flocculant are now used after biochemical treatment to make the effluent CODcr ≤ 80mg

/L, chroma <40 times (COD removal of chlorine> 70%, decolorization rate ≥ 75%), which can meet the national first-class standard for comprehensive discharge of sewage, and the operation cost is slightly lower than that of sodium hypochlorite decolorization method Both economic aspects are reasonable

it has obvious treatment effect for high concentration and high chromaticity dye wastewater. For example, the process wastewater of edible clothing fat red and sunset yellow, cod960-2068mg/L, and the color index is 4096-65536 times. After treatment with

decolorizer, the COD removal rate is 60% - 79%, and the chromaticity removal rate is 75-96.8. Users of

are also very satisfied. Tianjin Research Institute of chemical industry has also done a lot of work in developing series products and other applications of high-efficiency decolorizer. The industrial test of oil removal flocculation was carried out on the wastewater device of the first oil production plant of Xinjiang Petroleum Administration Bureau. In the past, the oil content of effluent was 117mg/L, and the high-efficiency Decolorizing Flocculant series products can reach 23

mg/L, which meets the design requirements (the design requirements are 50mg/L), and overcomes the problems of foam caused by the previous agent

and has been highly praised by users

at present, high-efficiency Decolorizing Flocculant has formed an annual output of 2 Jaw quality is inferior, with a production capacity of 1000 tons. In 1999, 86 tons of industrial products were produced, with an output value of about 714000 yuan. The aerospace dream of the testing machine has a direct economic benefit of about 150000 yuan; The treatment of waste water is about 2.5 million cubic meters. In 2000, 245 tons were produced and sold, the output value was about 1.96 million yuan, and the direct economic benefit was about 400000 yuan. About 34million cubic meters of wastewater were treated. The products have been sold to Jiangsu, Xinjiang, Beijing, Liaoning and other places, and abroad have been sold to Thailand, the Philippines and other countries
