【摘要】 在油田洗井废水处理及回用的过程中 ,利用了移动式处理装置。由于洗井废水水质复杂、变化范围大 ,一般的投药控制方法难以应用。通过对絮凝剂性能的研究及水质变化的统计分析 ,在处理过程中采用了分时段不同投药量的投药控制方法 ,可以满足处理要求 ,降低了药耗 ,具有实际应用价值更多还原

【Abstract】 Portable treatment units were used in the treatment and reuse of the waste water from the wash water injection wells in oil fields.As the quality of the waste water from wash water injection wells is complicated and has a wide range of variation,it is difficult to use usual methods for the controlling of dosing.Based on the study of the performances of flocculents and the statistical analyses of the variation of the quality of the water,a method of using different dosage in different periods of time swa used for the control of dosage,which satisfied the reauirements for treatment,reduced the consumption of chemicals and is ,therefore,practically applicable.更多还原
