Problems solved by technology

At present, there are many methods for sewage treatment, and chemical agents are generally used to treat them. However, the decolorization effect of the existing coagulants for wastewater treatment is poor, and the COD treatment in wastewater is ideal for combined treatment.
And it is easy to foul during the treatment process

Abstract

The invention discloses a dyeing wastewater treating agent and a preparing method thereof. The dyeing wastewater treating agent is prepared from aluminum hydroxide gel, sodium metaaluminate, lime, grain starch, sodium silicate, sodium lignin sulfonate, activated carbon, a powder auxiliary, urea and water. The aluminum hydroxide gel, the sodium metaaluminate, the sodium silicate, the sodium lignin sulfonate, the activated carbon and the powder auxiliary are sequentially added to a reaction kettle, the lime is added into water to prepare lime water, the lime water is slowly added into the reaction kettle while being stirred, heating is conducted at a constant temperature, and stirring is even; then, cooling is conducted, and the grain starch and the urea are added to be evenly stirred at the constant temperature. According to the dyeing wastewater treating agent and the preparing method thereof, organic pollutants and heavy metal in wastewater can be effectively removed, the settling time of aggregates can be shortened, the cost of wastewater treatment is reduced, and the efficiency of wastewater treating is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a printing and dyeing sewage treatment agent and a preparation method thereof. Background technique [0002] With the development of society, the textile industry is also developing rapidly. my country is the world's largest producer and exporter of textiles and clothing. The textile industry is a labor-intensive industry, so it plays a vital role in solving social employment problems. However, textiles need to be printed and dyed, and a large amount of wastewater will be generated during the printing and dyeing process. The sewage mainly contains dirt, grease, salt on textile fibers, and various sizing, dyes, surfactants, and additives added during processing. , acid and alkali, etc. If the waste water is discharged directly without treatment, it will cause great pollution to people's domestic sewage. [0003] Wastewater is characterized by high concentration of orga...
