摘　　要：目前某油田污水水质改性技术中使用的碱度调节剂是复合碱(氢氧化钠和氢氧化钙),复合碱处理污水过程中产生的污泥量大,同时结垢严重,为此研究了新的低污泥产出量水质改性配方:800 mg/L氢氧化钠溶液+13 mg/L混凝剂。现场应用试验表明,新的低污泥产出量配方能调节水的pH值至7.82,结垢现象明显减轻,平均腐蚀速率为0.065 mm/a。处理后水的含油量、悬浮固体含量、粒径中值、SRB菌含量等指标均能达到注水标准,且产生的污泥比使用原复合碱时减少了约67.2%,新配方水质改性效果较好。At present,the alkalinity regulator used in sewage water quality modification technology of an oilfield is compound alkali(sodium hydroxide and calcium hydroxide),but the sludge quantity produced in the process of compound alkali treatment is large,and the scaling is serious.Therefore,a new water quality modification formula with less sludge:800 mg/L NaOH solution+13 mg/L coagulant.The field application test shows that the new formula for less sludge can regulate the pH of water to 7.82,the scaling problem is alleviated,and the average corrosion rate is 0.065 mm/a.After treatment,indicators such as the oil content,the content of suspended solids,the median of particle size and the content of SRB bacteria can all reach standards of water injection.The sludge produced is about 67.2%less than that when using the compound alkali.The water quality modification effect of the new formula is better.
