ABSTRACT
Aiming at the oilfield sewage containing soluble sulfide, through the introduction of et aeration device, this paper proposes an advanced technology with good effect on sulfur removal. Field test data show that, when the sulfur in the feed water of the 1# reaction buffer tank (5 - 8 mg/L ) does not change too much, the concentration of sulfide in the effluent drop from 5 - 7 mg/L to 0. 2 - 0. 6 mg/L; hydrogen sulfide content in air at the top of the tank also drop from he original 10 - 40 mg/m³ to 0 - 5 mg/m³. Due to the introduction of the flotation effect in the processing link, the oil concentration in the effluent of reaction buffer tank is reduced correspondingly while speeding up the sludge settling velocity, so that the content of suspended solids and oil reaching the standard have improved under the same conditions. The flotation process is introduced into crude oil sewage treatment process mainly based on the sedimentation process, which is a breakthrough for the principle and technology of current crude oil sewage treatment.
