稠油污水处理系统改造与絮凝剂筛选试验研究

对新疆克拉玛依油田公司百口泉采油厂稠油污水处理系统进行了改造,并对絮凝剂的筛选进行了试验.结果表明：无机絮凝剂与有机絮凝剂联合作用,可对污水中所含有的污油和有机物杂质的悬浮物产生很好的絮凝沉降效果.加药浓度、加药顺序及沉降时间均对絮凝沉降效果有一定的影响.改造后的污水处理系统实现了污水达标回注,降低了药剂成本,产生了明显的经济效益.

Remolding on Effluents Processing System of Heavy Oil and Studying on Sifting Test of Flocculant

The extracted effluents processed by the heavy oil effluents processing station in Baikoquan Extract Oil Factory of Xinjiang Karamay Oil Field Company has characteristics such as high oil content,high emulsification extent, high suspended substance content and high temperature etc, which make it difficult to process the effluents in the heavy oil. Therefore, remolding has been done in its processing system and the test in the sifting of flocculant as well. It shows that the mixture of inorganic flocculant and organic flocculant may bring a good flocculating settling effect to the sludge suspended substance of the dirty oil and organic substance in the effluents. Flocculant concentration, flocculant order and settling time have an effect on the flocculating settling. Remolded effluents processing system has made the effluents reach a standard and pour it back to the oil layer,which has reduced the cost of the agent and brought a good economic benefit.
