The invention discloses an anaerobic biological treatment process for treating sewage, which belongs to the technical field of sewage treatment. In the first step, the pretreated sewage is passed into the anaerobic tank, the compound microbial inoculum is pre-placed in the anaerobic tank, the carbon source is added, and the preliminary anaerobic treatment is carried out under the conditions of ultrasound and irradiation; the third step, the irradiation is removed, Maintain ultrasonic conditions and continue anaerobic treatment to obtain standard discharge water. In the invention, the microorganisms are encapsulated in the capsules to form a composite microbial inoculant, which provides good conditions for the attachment and growth of microorganisms, and effectively promotes the anaerobic treatment effect of microorganisms on sewage; , not only can realize the reuse of waste, but also will not bring new difficult sludge problem; improve the deficiencies and defects of the existing technology, to achieve the maximum effect of biological anaerobic technology to treat sewage. |
