| titleOfInvention | Water-dispersible diatomite composite flocculation dehydrating agent and application thereof |
| abstract | The invention provides a water-dispersible diatomite composite flocculation dehydrating agent and application thereof, wherein the dehydrating agent is prepared by the following method: in an inorganic salt aqueous solution medium, taking a cationic polymer or a nonionic polymer as a dispersion stabilizer, and carrying out in-situ free radical graft copolymerization on a water-soluble anionic monomer, a water-soluble cationic monomer, acrylamide and diatomite under an initiator to obtain the dispersed diatomite composite flocculation dehydrating agent. The dehydrating agent has high dissolving speed, full dissolution and small initial viscosity, so that the dehydrating agent has higher dehydrating effect; the sludge dewatering and reduction operation can be realized; the higher content of the diatomite obviously reduces the product cost and improves the market competitiveness. The specific resistance of the sludge in the sludge dehydration process is 2.82 multiplied by 10 13 ～4.15×10 13 m/kg is reduced to 1.17X 10 12 ～8.37×10 12 m/kg, and the capillary washing time is reduced from 124-158 s to 11.2-22.4 s. |
