摘要
随着各炼油厂加工深度和加工能力的日益提高 ,排放的污水水量不断增加 ,水质不断恶化 ,原有的“老三套”中的曝气装置已无法满足生产需要。为此 ,不少炼油厂都针对各自的具体情况 ,对生化系统进行了技术改造 ,主要措施有 :淘汰现有表曝池、改造现有表曝池、向表曝池中投加多孔物质或硝化反应与反硝化菌。
Along with raising of processing depth and processing capacity in every Oil Refinery day by day,the discharging amount of sewage continuously increasing,water quality become worse to the worst and the existing aeration device of 'the old three sets' can not meet the needs of production.So,according to self's special conditions,most of the Oil Refinery,all carry out technological reforming for the biochemical system,main measures are:eliminating the existing aeration tank,reforming the existing aeration tank,adding in porous matter of denitrobacteria in aeration tank increasing building biochemical pre-treatment facilities and making the first-class biochemical treatment change into the second biochemical treatment.
