Description
Technical Field
The invention belongs to the technical field of urban and agricultural domestic sewage treatment equipment, and particularly relates to an integrated reinforced anaerobic membrane type photobioreactor.
Background
The combination of high concentration microalgae culture and wastewater treatment has received increasing attention due to its industrial potential. Microalgae in suspended or attached growth mode have proven effective in removing nutrients and some other contaminants from wastewater. The microalgae biomass produced during wastewater treatment is increasingly considered as a potentially sustainable source for various products such as cosmetics, pigments and biofuels. Microalgae-based wastewater treatment can be accomplished in two engineering systems, including open ponds and photobioreactors. While open ponds are generally easy to design, build and operate, significant limitations associated with this technology include water evaporation, large space requirements, algal culture contamination, and lack of control over operating parameters, whereas photobioreactors have the disadvantages of poor settleability and biomass being easily washed out. With the continued development of these systems, the implementation of the membrane photobioreactor concept recently combines photobioreactors with membrane filtration processes.
Membrane photobioreactors can not only produce high concentrations of biomass but also significantly reduce the nutrients such as nitrogen and phosphorus and the smaller footprint requirements, primarily due to the ability of membrane photobioreactors to independently control Hydraulic Retention Time (HRT) and Solids Retention Time (SRT). The membrane type photobioreactor utilizes autotrophic effect of microalgae, takes carbon dioxide in air as a carbon source, and removes nitrogen and phosphorus in water. Conventional membrane bioreactors typically have anoxic and/or anaerobic zones to achieve complete denitrification/nitrification.
Therefore, the invention mainly solves the problem of water eutrophication caused by low organic matter removal efficiency and incapability of removing N, P in the anaerobic sewage treatment process.

The reactor employs granular activated carbon GAC carriers instead of conventional anaerobic technology because the biomass attached to GAC is more resistant to temperature fluctuations, shock loading and changes in influent water concentration or composition than conventional suspended biomass. This is an important factor for anaerobic treatment of actual low-concentration town sewage at ambient temperature. In addition, the GAC in the reactor may also promote COD removal and methanogenesis, since GAC and its attached organisms are able to adsorb and biodegrade organic compounds in the wastewater.
GAC has conductive property, and a large amount of electrogenic bacteria such as Geobacter and methanogen hydrogenophilus can be enriched in a biomembrane attached to the GAC to stimulate and generate direct inter-inoculation electron transfer DIET, so that the methanogenesis process is enhanced. The introduction of the GAC can also promote the enrichment of methanogens, promote the co-nutrient metabolism of the volatile fatty acid VFA and improve the methane yield in the anaerobic process.
