摘    要:川东气田生产过程中产生的废水含有硫化物,且色度深、浊度大。为测定废水中的S2-含量,实验探索了将S2-氧化成SO2-4后用离子色谱测定的方法。进行了S2-的转化率实验,结果表明:S2-含量在0~2.7mg/L范围内可以被完全氧化成SO2-4,转化率为98.8%~108.0%。同时进行了该方法的精密度和准确度实验,并与碘量法进行了对比,对同一标样和实际样品的测定两种方法的结果吻合较好,该方法测定钻井废水中的S2-含量,可以避免色度、浊度的干扰,且简便、灵敏、准确

关 键 词:川东钻探公司  钻井液  污水处理  含硫化合物  离子色谱法  测定

Abstract:The sewage produced during gas field development in east Sichuan Province contains sulfide,with dark chroma and heavy cloudiness.Authors tested the method of ion chromatography to determine S 2- content in the sewage after S 2- was oxidized into SO 2- 4.The conversion ratio of S 2- was worked out in laboratory.The results showed that S 2- content within 0~2.7mg/L could be oxidized totally into SO 2- 4 with conversion ratio of 98.8% ~108.0%.After precision and accuracy experiments,this method was compared with iodimetry method in laboratory and the results of the two methods coincided fairly for determining stadard and actual samples with same S 2- content.This method avoided the confusion from chroma and cloudiness and was simple,sensitive and accurate for determining the S 2- content in drilling sewage.
Keywords:East Sichuan drilling company    drilling fluid    sewage disposal    sulfide    ion chromatography    determination
