近年来,频发的石化事故所产生的废水给水体环境造成了严重污染。针对重庆市某天然气净化厂事故,在调查事故废水种类和水量的基础上,根据厂区现有排水系统、生产工艺及平面布置情况,采用大围堰的形式对1114 m3事故废水进行收集;然后通过厂区现有及拟建排水系统将其送至事故池进行储存;最终利用潜污泵将废水提升至厂区污水处理单元进行处理,有效减少事故废水对于环境的影响。
近年來,頻髮的石化事故所產生的廢水給水體環境造成瞭嚴重汙染。針對重慶市某天然氣淨化廠事故,在調查事故廢水種類和水量的基礎上,根據廠區現有排水繫統、生產工藝及平麵佈置情況,採用大圍堰的形式對1114 m3事故廢水進行收集;然後通過廠區現有及擬建排水繫統將其送至事故池進行儲存;最終利用潛汙泵將廢水提升至廠區汙水處理單元進行處理,有效減少事故廢水對于環境的影響。

The accidental wastewater collection and disposal scheme of a natural gas purification plant in Chongqing was intro-duced ,according to the severe pollution of water environment caused by the petrochemical industry accidents which happen fre-quently in recent years and the documentation requirements of an emergency notice about urging the petrochemical enterprise to carry out several security and environmental protection key works which was issued by the State Production Safety Supervision Administration and the State Environmental Protection Administration in 2006 .First , the type and quantity of accidental wastewater were determined ,and the accidental wastewater of 1114 m3 was collected using the big cofferdam based on the con-ditions of existing drainage system ,manufacturing technique ,and layout of the factory .Secondly ,the accidental wastewater was sent to the accidental pool for storage through the existing and proposed drainage systems .Finally ,the accidental wastewater was treated by the wastewater treatment unit in the factory through lifting of submersible sewage pump ,which can reduce the impacts of accidental wastewater on water environment .
