anaerobic digestion wastewater treatmen technology

anaerobic digestion wastewater treatmen technology is an efficient sewage treatment method in which the organic matter in sewage is decomposed, metabolized and digested by anaerobic bacteria under the anaerobic condition, so that the organic matter in sewage is greatly reduced and biogas is produced.

As an important form of biological treatment, anaerobic digestion wastewater treatmen is gradually developing a series of new anaerobic treatment processes and structures, gradually overcoming the shortcomings of traditional anaerobic digestion wastewater treatmen processes, and making great progress in theory and practice.

By utilizing the metabolic characteristics of anaerobic microorganisms, the reduced organic matter in sewage is used as the hydrogen acceptor without the need of providing exogenous energy, and methane gas with energy value is produced at the same time.Biogas (including gaseous substances such as CH4, CO2, N2, H2, O2, H2S, etc.) produced when organic matter is degraded can be actively utilized to generate economic value.

anaerobic digestion wastewater treatmen in the process, the organic matter in wastewater is finally converted into methane, carbon dioxide, water, hydrogen sulfide and ammonia by the joint action of a large number of microorganisms.In this process, the metabolic processes of different microorganisms affect and restrict each other, forming a complex ecosystem.The description of anaerobic process of macromolecular organics is helpful for us to understand the basic content of this process.

anaerobic digestion wastewater treatmen development

anaerobic digestion wastewater treatmen infrastructure investment is higher than that of oxidation ditch and SBR process, but with the increase of scale, the infrastructure cost of oxidation ditch and SBR also increases exponentially, while the investment of conventional activated sludge method increases in a small proportion, and the gap between the two is getting smaller and smaller.

When the sewage plant reaches a certain scale, the investment of conventional activated sludge method is less than that of oxidation ditch and SBR, so the larger the scale of sewage plant, the greater the advantage of conventional activated sludge method.The main disadvantages of conventional activated sludge method, A/O method and A2/O method are that there are many treatment units and complicated operation and management, especially the anaerobic digestion of sludge requires A high level of management, and the methane generated in the digestion process is flammable and explosive gas, which requires safe operation. All these increase the difficulty of management.

However, because large sewage treatment plants are located in large cities, with strong technical force and high management level, they can meet this requirement. Therefore, the disadvantages of conventional activated sludge method will not be a limiting factor.
