Abstract
The requirements for clean water in marble processing are partially realized by treating and recycling slurry wastes from the cutting and processing plant. In this study, the flocculation of calcitic and dolomitic (21.2 % MgO) marble wastes was investigated using six flocculants with different molecular weights and anionic levels. Nine solutions between 0.1 and 2.5 mg/L were prepared, and marble waste samples were treated in natural, slightly acidic, and alkaline media. The anionic flocculants had a more dramatic effect on the slower-settling dolomitic marble than the calcitic marble. Calcite precipitation was better in an alkaline medium, while dolomitic marble precipitation was better at a slightly acidic pH of 6.
Zusammenfassung
Ein Teil des Frischwasserbedarfes in der Marmorverarbeitung wird durch Klärung und Rückführung des Prozesswassers der Schneide- und Verarbeitungsanlagen realisiert. In dieser Studie wurde die Flockung von kalzitischen und dolomitischen (21.2% MgO) Marmorabgängen untersucht. Sechs Flockungsmittel mit verschiedenen molekularen Gewichten und Anionengehalten wurden erprobt. Neun Lösungen zwischen 0.1-2.5 mg/L wurden erstellt. Marmorabgänge wurden in natürlichem, schwach sauren und alkalischem Medium behandelt. Die anionischen Flockungsmittel hatten im Vergleich mit Kalzitmarmor einen dramatischeren Effekt auf den langsamer absinkenden Dolomitmarmor. Das Ausfällen von Kalzit war in alkalischem Medium besser, wogegen die Präzipitation von Dolomitmarmor bei schwach saurem pH 6 besser war.
Resumen
Los requerimientos para limpieza de agua en el procesamiento de mármol son parcialmente realizados por tratamiento y reciclado de los lodos residuales que provienen de la planta de procesamiento y corte. En este estudio, se investigó la floculación de residuos de calcita y dolomita (21,2% MgO) usando seis floculantes con distintos pesos moleculares y niveles aniónicos. Se prepararon nueve soluciones entre 0,1-2,5 mg/L y las muestras de residuos fueron tratadas en medio natural, ligeramente ácido y alcalino. Los aniones floculantes tuvieron un efecto más significativo sobre el residuo de mármol dolomítico, de más lenta sedimentación, que sobre el mármol calcítico. La precipitación de calcita fue mejor en medio alcalino mientras que la de dolomita lo fue en un medio ligeramente ácido (pH 6).
摘要
大理石切剤¸加工工厂泥浆的处理与利用能够一定程度上弥补加工厂清水需求的不足。利用不同分子量和阴离子水平的六种絮凝剂研究了含方解石和白云石(21.2% MgO)泥浆的絮凝作用。事先制备9份浓度为0.1~2.5 mg/L溶涬分别在自然、微酸和碱性条件下进行大理石厂泥浆处理。阴离子絮凝剂对扩较慢的白云质大理婦³¥浆的絮凝作用比含方解石大理婦³¥浆效果明显。碱性环境利于含方解石泥浆扦,而弱酸环境(pH=6)利于含白云质泥浆扦。
