| 摘 要：探討了電石法PVC生產(chǎn)中的三廢治理方法。電石渣漿廢水可直接用作乙炔發(fā)生器的工藝用水。PVC母液水、聚合釜等設備沖洗水可進(jìn)行深度處理后回用，高沸塔釜液可采用蒸餾或焚燒法處理，可用沉淀法處理含汞廢水。電石渣主要用于建材或用作化學(xué)中和劑�？刹捎米儔何�、膜分離工藝等方法處理氯乙烯精餾塔尾氣和PVC干燥尾氣等。通過(guò)改進(jìn)電石法PVC的生產(chǎn)工藝，可以大幅度降低三廢量。 |

| Abstract：Treatment of wastes formed in the PVC production of calcium carbide route was investigated. The waste water from carbide slag may be used directly for the generation of acetylene. The PVC mother solution and equipments washing water can be recycled after deep treatment. Kettle liquid with high boiling point may be treated by distillation or incineration. Waste water containing mercury may be treated by precipitation. The carbide slag is used as building material or chemical neutralizer. Tail gas from vinyl chloride distillation tower and PVC dryer may be treated by pressure swing adsorption and membrane separation. |
