Abstract

The invention discloses an anaerobic biological agent and an anaerobic treatment method using the same, belonging to the technical field of biological sewage treatment. The anaerobic biological agentcomprises a biological synergistic carrier and a composite microbial agent adsorbed on the biological synergistic carrier. The composite microbial agent comprises the following components in parts byweight: 4-8 parts of bacillus subtilis, 2-5 parts of bacillus cereus, 3-4 parts of bacillus licheniformis, 1-4 parts of bacillus pumilus, 4-8 parts of a biological factor supplement and 4-8 parts of anutritional agent. The method has the advantage that the sewage treatment efficiency of methanogens is improved.

Description

technical field [0001] The invention relates to the technical field of anaerobic treatment, in particular to an anaerobic biological bacterial agent and an anaerobic treatment method using the bacterial agent. Background technique [0002] Upflow anaerobic sludge bed is an anaerobic biological method for sewage treatment, and it is one of the most widely used methods in modern high-efficiency anaerobic treatment processes. [0003] When the upflow anaerobic sludge bed treats sewage, the sewage enters from the bottom of the reactor and is driven by hydraulic force, and the sludge is in a state of expansion in the reactor. After the mixed solution is fully reacted, it enters the sedimentation zone with an expanded cross-sectional area. After passing through the three-phase separator, the generated biogas enters the gas collection system from the upper part, and the sludge returns to the reaction zone by gravity. Thereby completing the treatment of sewage. The Chinese inventi...
