摘　　要：再生水回用是解决水资源短缺的主要方法之一,而提高再生水水质和处理能力,降低成本至关重要。通过混凝烧杯试验,初步研究了一种新型生物多糖助凝剂配合聚合氯化铝应用于再生水处理的助凝效果。结果表明,与单独使用聚合氯化铝相比,添加少量生物多糖助凝剂不仅可改善出水水质,而且至少可提高20%的水处理能力,同时降低17.8%的药剂成本,具有巨大的经济效益和社会效益。Reclaimed water reuse is a main method to solve the lack of water resources, whereas to improve the water quality of reclaimed water and water treatment capacity and to reduce the cost treating reclaimed water are essential. The enhanced coagulation effect of a new bio-polysaccharide flocculant-aid coupled with polymeric aluminum chloride （PAC） in the reclaimed water treatment was preliminarily studied by coagulation jar test. The results show that compared to PAC alone, adding a small amount of bio-polysaccharide flocculant-aid can not only improve the effluent quality, but also increase the water treatment capacity at least by 20% , while reducing the cost of reagents by 17.8%. The enormous economic and social benefits can be obtained.
