preparation example Construction

[0034] The preparation method of the sewage biological fermentation treatment agent of the oil production plant comprises the following steps:

[0035] S1: Put the waste liquid from the vinegar factory to stand for clarification to obtain the supernatant, then heat the supernatant to 82-84°C for evaporation and concentration until the pH value is 3.6-3.8, stop heating, and let stand at room temperature Activate for 16-17 hours, then add ammonium carbonate to adjust the pH value to 5.9-6.1 to obtain humic acid solution, dry the humic acid solution at 106-110°C until the water content is ≤8%, crush it and pass it through a 200-400 mesh sieve to produce get humic acid;

[0036] S2: Mix the humic acid prepared in step S1 with Flavobacterium, biological growth stimulator, biological nutrient, and water evenly, and culture at a temperature of 30-38° C. for 2-8 hours to prepare a culture solution;

[0037] S3: Adjust the pH of the culture solution prepared in step S2 to 6.5-6.9 with...

Abstract

The invention discloses a preparation method of an oil recovery plant sewage biofermentation treating agent. The oil recovery plant sewage biofermentation treating agent is prepared from Flavobacterium, wood charcoal, humic acid, a biological growth irritant, a biological nutrient, a coagulant aid, a demulsifier, a bactericide, a deoxidizer, an enzyme, a flotation agent and a corrosion and scale inhibitor. The preparation method of the oil recovery plant sewage biofermentation treating agent comprises the following steps: humic acid preparation, culture fluid preparation, pH value regulation, mixing and the like. The oil recovery plant sewage biofermentation treating agent has the advantages of no toxicity, high safety, environment friendliness and the like, and does not influence the human health. When the oil recovery plant sewage biofermentation treating agent is used for treating sewage, the SS (suspended sediment) removal rate is up to 99.14-99.29%, the COD (chemical oxygen demand) removal rate is up to 99.03-99.12%, and the oil removal rate is up to 99.06-99.15%.

Description

technical field [0001] The invention relates to the technical field of preparation of sewage treatment agents, in particular to a method for biological fermentation treatment agents for sewage in oil production plants. Background technique [0002] The chemical precipitation method is widely used in sewage treatment. It is to add some chemical agents to the waste water to make it chemically react with the pollutants in the waste water to form insoluble solid products, and then separate the solid and liquid to remove the water. A method of contamination. At present, in some industries, such as coal slime water, oil field wastewater, printing and dyeing wastewater, papermaking wastewater, etc., the fermentation treatment agent used has poor treatment effect, high fermentation treatment agent cost, and some enterprises have caused serious corrosion of equipment. [0003] The produced water of the oil field oil production plant is extracted from the oil layer together with the ...
