摘　　要：采用化学混凝法对江汉油田钻井污水进行了室内处理实验。实验结果表明,污水处理时所选絮凝剂的种类、加入量、加入顺序、温度和加入后的沉降时间等都会影响处理效果。采用单一无机化学药剂,沉降速度较慢,故考虑将无机和有机药剂复配使用,即利用先加无机药剂后再加入有机药剂的顺序处理该油田钻井废水。该实验结果为油田钻井污水无害化处理提供了基础资料。The laboratory experiment on drilling sewage disposal using chemical flocculation method carried out in Jianghan Oilfield. Good results have been obtained. The removal ratios of COD, suspended particle and chromium are high. The type and dosage of reagents, sedimentation time and functional temperature have influence on disposing effect. The combination of inorganic and organic reagents has better effect than single reagent. In the treating process, the proper disposal process for treating drilling wastewater of Jianghan Oilfield is firstly adding inorganic reagent and then adding organic reagent. The experimental result in laboratory can provide some basic data for applying this method in oilfields.
