摘要： The present invention falls within the field of purifying oil-laden wastewater, which provides a method for purifying coke-cooling wastewater in a delayed coking process in petroleum chemical field. The method comprises the following steps: (a) cooling the coke-cooling wastewater produced in a delayed coking process to 5-55° C. under 0.1-0.25 MPa absolute pressure, to obtain cooled coke-cooling wastewater; (b) subjecting the cooled coke-cooling wastewater to solid-liquid separation, to obtain a coke breeze phase and a liquid phase; (c) further separating the obtained liquid phase, to obtain an oil phase and a water phase; and (d) further discharging water from the obtained oil phase, to obtain the separated oil phase. The present invention also provides an equipment for carrying out the method. The method of the present invention has the following advantages: low cost for the equipment, good effect for treating coke-cooling wastewater, effectively preventing sulfur pollution and foul odor pollution, saving resources and improving the overall utility of the resources, and improving the cool coking efficiency.
摘要翻译：本发明属于净化含油废水领域，提供了石油化工领域延迟焦化工艺中焦化冷却废水的净化方法。该方法包括以下步骤：（a）在0.1-0.25MPa绝对压力下将延迟焦化工艺中生产的焦炭冷却废水冷却至5-55℃，得到冷却焦炭冷却废水; （b）将冷却的焦炭冷却废水进行固液分离，得到焦炭微相和液相; （c）进一步分离得到的液相，得到油相和水相; 和（d）从得到的油相中进一步排出水，得到分离油相。本发明还提供了一种用于执行该方法的设备。本发明的方法具有以下优点：设备成本低，处理焦化废水效果好，有效防止硫污染，臭臭污染，节约资源，提高资源整体效用，提高冷却效果焦化效率。
