Abstract
The invention relates to a controllable double-circulation anaerobic reactor and an application and aims to solve the problems that existing IC (internal circulation) reactors are high in start-up cost and cannot be applied to treatment of refractory or toxic wastewater. The controllable double-circulation anaerobic reactor comprises a casing, a water inlet system, a water outlet system, a biogas collection system, an IC system, an EC (external circulation) system, an IC conversion system, an EC conversion system and a constant-temperature control system. The anaerobic reactor is applied to treatment of refractory or toxic wastewater which is traditional Chinese medicine wastewater, printing and dyeing wastewater or landfill leachate. The IC and EC intensity can be controlled manually when the reactor is started and the refractory or toxic wastewater is treated, and the mass transfer efficiency of sludge and wastewater is improved, so that degradation of pollutants is promoted. The reactor is applied to the wastewater treatment field.
Description
technical field [0001] The invention relates to an anaerobic reactor and its application. Background technique [0002] Anaerobic treatment technology is a low-cost wastewater treatment technology that effectively combines wastewater treatment with energy recovery and is widely used in industrial wastewater treatment. The development of anaerobic reactors has gone through three stages: the first generation of reactors, represented by anaerobic digesters, where wastewater and anaerobic sludge are completely mixed, is a low-load system; the second generation of reactors, which can convert solids The separation of residence time and hydraulic retention time can maintain a large amount of activated sludge and a long enough sludge age, and pay attention to the cultivation of granular sludge, which is a high-load system; the third-generation reactor, in the solid residence time and hydraulic retention time Under the premise of phase separation, the solid and liquid phases are ful...
