摘要
文章针对高氯根气田水特点,使用硫酸锰代替GB/T 11914-1989《水质化学需氧量的测定重铬酸盐法》中的硫酸银作为催化剂,确定了硫酸锰催化法测定化学需氧量的试验条件。分别在4个实验室间开展比对测试,并对川西北气矿3个典型井站高氯根气田水开展现场应用,测定结果的相对偏差均在规定范围内,取得了良好的应用效果。
Aiming at the characteristics of high chloridion gas field water, manganese sulfate is used as the catalyst instead of silver sulfate is which reported in GB / T 11914- 1989 'chemical oxygen demand in water quality determination of dichromate method to determine the test conditions for the measurement of COD. Comparative studies were carried out among 4 laboratories respectively, and field application of the method was performed upon 3 typical well stations in the Northwest Sichuan gas field. The relative deviation of the measurement results are within the specified range, obtaining satisfactory application effects.
