摘　　要：姜黄素废水成分复杂、色度大,在详细分析其水质特点的基础上,以季胺盐型阳离子高分子絮凝剂(YJD)为混凝剂,以Ca(OH)_2为pH值调整剂,对其进行混凝预处理试验,考察了混凝剂(YJD)投药量、混凝pH值以及温度对絮凝沉淀性能的影响,为混凝法预处理姜黄素废水提供了参考依据。Turmeric industry wastewater has high chroma, and its component is complex. Based on the analysis of the water quality specialties, using quarternary ammonium salt-type cation macromolecule flocculant as coagulant, calcium hydroxide as pH value rectifying agent, the test of coagulation pre-treatment of turmeric industry wastewater is carried out. The influence of the coagulant dosage, the pH value and the temperature on the performance of flocculation and deposition is investigated, which provides the reference for the coagulation pre-treatment of turmeric industry wastewater.
