Ceramic water quality adaptability peptizer containing polyamine epoxy adduct polymethylene phosphonate
The invention belongs to the technical field of fine chemical engineering of ceramic additives. The invention relates to a ceramic water quality adaptability peptizer, in particular to a ceramic waterquality adaptability peptizer containing a polyamine epoxy adduct polymethylene phosphonate. The ceramic water quality adaptability peptizer is formed by compounding the effective components including polyamine epoxy adduct polymethylene phosphonate, polyacrylate and (without crystal water) metasilicate (M2SiO3.mH2O) with water in an amount which is twice the weight of the effective components. The polymethylene phosphonate containing the polyamine-epoxy adduct is obtained by addition and chain extension of polyamine and polyalkylene glycol diglycidyl ether, followed by a Mannich reaction andneutralization with phosphorous acid and formaldehyde. The composite peptizer is used for ceramic slurry, can significantly improve the water quality adaptability of the peptizer, and has the characteristics of strong adaptability, good peptizing effect, small thixotropy, high water-reducing rate and the like.

A method for treating polluted acid wastewater with modified red mud powder
The invention discloses a method for processing acidic wastewater by using modified red mud powder. The method comprises the following steps of A, adding lime milk to adjust a pH value of the acidic wastewater to 6.5-7.5; B, adding the red mud powder into the acidic wastewater processed by the step A according to a mass ratio of the acidic wastewater to the red mud powder being 200:1.5-2.6 ml / g; stirring for 2-3 h at a temperature of 30 DEG C, standing and precipitating for 30-60 min; and separating a supernatant by centrifugation. The method takes full use of the most universal lime neutralization system for processing the acidic wastewater, without reconstruction. Raw materials are cheap; water quality has high adaptability; a process flow is short; preparation and operation of the red mud powder are simple; and processing cost is low, thereby meeting actual requirements of enterprises. Compared with a lime neutralization method, the method provided by the invention takes full use of the characteristics of the red mud residues, and reduces use amount of quick lime. Effluent has low hardness, and does not block pipes and valves or influence stable running of a system. A processing effect is good; and the processed water can be recycled easily. The red mud powder has the advantages of good sediment dehydration property, relatively high metal quality and easy recovery utilization.
