Problems solved by technology

[0003] General physical and chemical methods are not effective in treating high-concentration organic wastewater. Anaerobic biological method is currently a relatively mature and effective method for treating high-concentration organic wastewater. It mainly utilizes the metabolic characteristics of anaerobic microorganisms. Under the condition of providing external energy, the reduced organic matter is used as the acceptor, and methane gas with energy value is produced at the same time

Abstract

The invention relates to a spiral symmetrical flow anaerobic reactor, which comprises a water distribution region, a reaction region and a three-phase separation region, wherein the water distribution region, the reaction region and the three-phase separation region are respectively arranged on a reactor from bottom to top, the water distribution region comprises a bottom plate and a lower post body, the upper surface of the bottom plate is connected with the lower post body, the reaction region comprises a middle post body, the middle post body comprises a spiral flow reaction region and a free airspace region, a back flow pipe is arranged in the free airspace region, and a case of the three-phase separation region is respectively provided with a cone body, an upper post body and a coverplate from bottom to top. The spiral symmetrical flow anaerobic reactor has the advantages that the water distribution is uniform, the blockage is not easy to occur, the spiral symmetrical flow anaerobic reactor trends to the flat push flow state, the treatment efficiency is high, the liquid solid mass transfer effect is good, the organic load impact resistance capability is high, the intermediate product suppression is reduced, and the particle sludge and the recycled alkalinity can be effectively maintained.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, in particular to a spiral symmetrical flow anaerobic reactor. Background technique [0002] At present, the effective treatment of high-concentration organic wastewater in industrial wastewater is one of the difficult problems in the field of wastewater treatment, and it is also the key to realize the task of reducing COD (chemical oxygen demand). High-concentration organic wastewater generally refers to wastewater with COD above 2000mg / L discharged from papermaking, leather, food and other industries. Serious water pollution such as water hypoxia. [0003] General physical and chemical methods are not effective in treating high-concentration organic wastewater. Anaerobic biological method is currently a relatively mature and effective method for treating high-concentration organic wastewater. It mainly utilizes the metabolic characteristics of anaerobic microorganisms. Under the c...
