Problems solved by technology

The biogas produced by the anaerobic reaction is introduced into the biogas boiler to generate a large amount of water vapor, and the water vapor is evenly distributed in the UASB reactor through the air-supply pump through the pneumatic stirring rod. Although it can save energy, due to the need to Water vapor is passed into the UASB reactor, and oxygen will be entrained in the water vapor, and the water vapor will be partially liquefied after passing into the UASB reactor, which will gradually destroy the anaerobic environment inside the UASB reactor and change the pH value inside the UASB reactor. Changes the optimal living environment for anaerobic bacteria, greatly reducing the treatment efficiency

The invention is ingenious in structure, easy to use, can heat and keep the UASB reactor body in a heat conduction manner, has a good heat preservation effect, can reuse water, is more environmentally friendly and economical, and will not affect the internal environment of the UASB reactor body during the heating process , can guarantee a good purification effect.

Description

technical field [0001] The invention relates to the technical field of UASB reactors, in particular to a UASB reactor system with self-heating function. Background technique [0002] UASB has been used in wastewater treatment for more than 20 years. Compared with traditional anaerobic reactors (such as anaerobic ponds, septic tanks), UASB has shorter hydraulic retention time, longer solid retention time, maintains high concentration of microbial biomass, and can combine a large amount of highly active biomass , which greatly improves the stability of the sludge and the load capacity of the reactor, and is currently popularized all over the world for the treatment of high-concentration organic wastewater. In the UASB reactor, anaerobic bacteria use organic matter in anaerobic sludge as a substrate to purify sewage through degradation. The optimum growth temperature for most anaerobic bacteria (mainly methanogens and hydrolytic bacteria) is 30-35°C. However, in my country, ...
