摘要
近年来,随着石化工业的迅猛发展,大量的水资源被耗用,造成的环境污染日益
严重,为了缓解水资源缺乏和水环境污染的现状,废水深度处理回用成为石化企业关注
的热点,但是由于经过二级处理后的石化废水具有成分复杂、难降解污染物多、不能满
足中石油回用水水质标准等一系列问题,制约了石化废水的回用。
论文阐述了研究的背景和意义,概述了石化废水回用水处理工艺单元技术,提出了
主要研究内容和处理工艺流程。论文分析了 OPHTS工艺特点,对生物活性碳净化机理
与功能进行了分析研究。采用 OPHTS、一多腔生物活性碳组合工艺,对石化废水回用水
污染物的去除规律及效果进行了试验研究。得到以下主要结论:通过BAC的微观结构
和生物量测定,证明固定化BAC的形成是由于炭粒表面的不均匀性、保护胶体和化学
键的综合作用所致;BAC能长期稳定地去除微量有机物是由于活性炭的吸附与工程歯
生物降解作用的协同作用;提出采用 OPENS.一多腔生物活性碳联用技术对石化回用水
进行处理的工艺技术路线,理论及试验表明,处理稳定可靠,效果良好;OPHT一多腔
生物活性碳联用技术连续试验结果表明,工艺能有效去处水中色、臭、味及粪大肠菌群。
浊度和粪大肠菌群去除率分别为92%、82.8%,出水无异臭味,表现出良好的感官效果;
系统对 ODM和TOC去除率分别可以达到70%和60%以上;生物活性炭工艺设备简单,
占地面积小,运行管理方便,在实现石化废水回用的深度处理中有应用发展前景。
OPENS-一多腔生物活性碳组合工艺深度处理技术能够有效地去除水中的有机物、氨
氮,对水中的无机还原性物质、色度、浊度也有很好的去除效果,并且能有效地提高出
水水质,随着水处理技术的发展,必将获得更广泛的发展和应用。

Abstract
In recent years, along with the petrochemical industry rapid growing, massive used
water resources caused environment pollutions, which become worse nowadays In order to
ease the status of shortage and pollutions of the water resources, petrochemical companies
have more concerns on the wastewater re-usage area. However, petrochemical wastewater
brings some problem after the second stage of the re-usage treatment, such as component
complex, many polluted materials that difficult to degrade, cannot satisfy the reuse water
Standard of CNPC and etc, which constraints the reuse of the petrochemical wastewater.
The paper elaborated the background and significance of the research, outlined the unit
technology of petrochemical waste water treatment process and proposed the main research
content and treatment process. The paper has analyzed the characteristics of OPH'TS
Analyzed and studied the purification mechanism and the function of microbiological active
carbon. Study on the removal rule and effects of the petrochemical wastewater treat
experimental with OPHTS-A multi-cavity microbiological active carbon combined process
The main conclusions are as follows: Determining the micro-structure and biomass of BAC to prove that
the formation of immobilized BAC was due to the uneven surface of charcoal tablets and the protection of
colloid that combined effects from the chemical bond; BAC could remove long-term stability of
micro-organisms because of the activated carbon adsorption and biodegradation engineered strain of
synergies; the use of multi-cavity Ophitts-biological technology combined with activated carbon to the
petrochemical water processing line technology, and theoretical tests showed that dealing process stable
and have a reliable results; Opi'ts-multi-cavity biology activated carbon unites indicated with the
technical long-term test result. The craft can in the effective destination water in the color, smelly and the
taste. The chromaticity and the urbidity elimination rate respectively is 92% and 82.8%. The water
leakage not different stink, displays the good sense organ effect. The system may achieve above separately
70% and 60% to CODMN and the TOC elimination rate
