摘　　要：在阐述油气田含硫废水来源、危害、处理方法的基础上,结合含硫废水和油气田废水的特点,提出了现场处理工艺简单、易于操作的化学混凝复合催化氧化处理工艺技术室内研究方案。通过对化学混凝过程及催化氧化处理工艺条件研究,得到油气田含硫废水处理室内研究工艺过程。通过实验研究,所确定出处理配方、工艺条件能够把原废水CODcr为11000mg/L降低到74.3mg/L;原废水S2-为1096mg/L降低到0.7mg/L。处理后水质指标达到GB8978-96的一级排放标准。所研制的混凝剂PZCBS(水剂)、复合助凝剂ASNG+HNZJ、复合氧化剂FYHJ(复合)及复合催化剂FCHJ(钛/碳复合催化剂)对含硫废水的处理效果好。Based on the sources,pollutions,treatments of the sulphuric waste water,combined with the features of oil-gas field waste water,a simple and easy catalytic oxidation technical of chemical coagulation for disposing the sulphuric water was put forward.The laboratory treatment process about the sulphuric waste water was obtained through the research on chemical coagulation process and catalytic oxidation disposal conditions.Through treatment of sulfur waste water,its COD drop from 11000 mg/L to 74.3mg/L,the S2-contents can be drop from 1096mg/L to 0.7mg/L,the water quality can reach the GB8978-96 Level emissions standard.The treatment result of coagulants PZCBS(Water-soluble),compositive additives ASNG +HNZJ,compositive oxidants FYHJ and compositive catalysts FCHJ(Titanium/Carbon compositive catalyst) to sulphuric waste water is very good.
