Cationic polyacrylamide is a linear polymer compound, polyacrylamide is one of the highest price, because it has a variety of lively group, with many substances affinity adsorption to form hydrogen bonds. Mainly flocculation negatively charged colloid, with turbidity, bleaching, adsorption, adhesion and other functions, it is suitable for dyeing, paper, food, construction, metallurgy, mineral processing, coal, oil, aquatic products processing industry and other fermented organic colloid content higher wastewater treatment, especially for urban sewage, sludge, paper sludge and other industrial sludge dewatering process known as Better business aids.
Polyacrylamide widely used mining mineral products, such as copper, iron ore, gold flotation and tailings water treatment, coal washing and flocculation water treatment plant starch plant starch and alcohol and stillage recycling and so on. Today we talk about how to handle iron ore cationic polyacrylamide wastewater. There are four iron ore: hematite, magnetite, limonite and siderite. The content of the four wastewater generated by various substances vary, so we have to be treated separately in the selection of iron ore mine wastewater purifying agent time. After selection of low-grade iron ore (wet screening, gravity separation, magnetic separation, flotation) to obtain high-grade iron ore. Which mainly produces mineral processing waste water and waste pollution. These two things is what we want to remove substances harmful to the environment. Because sulfur, iron sulfate is generated, acidic wastewater, and many contain high concentrations of suspended solids, a variety of metal ions, pharmaceutical processing and the like. We used polyacrylamide and aluminum chloride or ferrous sulfate flocculants to deal with these wastewater. Concentrator great water, it should promote a multi-purpose water and improve wastewater reuse rate; Wastewater useful metal recovery; reduce waste water emissions. We use anionic polyacrylamide 1000-1400 molecular weight products of beneficiation wastewater conducted experiments and found that the experimental effect is obvious. Beneficiation wastewater via our experiments show that will not be used cationic polyacrylamide, all anionic flocculant anionic polyacrylamide and cationic polyacrylamide off than price is much lower, for us to choose.
