Abstract

The invention discloses a dyeing wastewater treating agent and a manufacturing method thereof. The dyeing wastewater treating agent is prepared from the following raw materials in parts by mass: 70-100 parts of diatomite, 40-70 parts of attapulgite, 90-120 parts of modified starch, 15-40 parts of acrylamide, 2-10 parts of ferrous sulfate, 20-30 parts of magnesium sulfate, 10-25 parts of meerschaum powder, 10-20 parts of crosslinked rectorite, 0.5-2 parts of polyacrylamide, 20-30 parts of cationic monomer, 0.17-0.21 part of initiator and 0.09-0.1 part of crosslinking agent. The treating agent can perform the flocculating settling purification and disinfection functions on the dyeing wastewater, has the characteristics of wide raw material sources, lower cost and favorable treatment effect, and is convenient for popularization and application.

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] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage. With the continuous development of industrial modernization, more and more industrial wastewater is discharged, which has a great impact on the environment and human life. If the sewage is not treated in time, not only It not only directly affects the quality of air and drinking water, but also indirectly affects the physical and mental health of human beings. [0003] The printing and dyeing industry consumes a lot of water, usually 100-200t of water is consumed per ton of textiles for printing and dyeing, 80%-90% of which is d...
