Abstract

The invention discloses a three-phase front processor for inner-loop anaerobic reactor, which contains at least two layers of inversed V-type horizontal pneumatic troughs of cross distribution and a 'pií‚-type horizontal collector trough connecting to a lift leg on the top, one end of the pneumatic trough connecting vertically to the side plate of the collector trough, and the lower end between adjacent horizontal pneumatic troughs having passages for liquid and particles. The device is characterized in that the passage opening connecting below middle of the pneumatic trough and the side-plate of collector trough is trapezoidal, the lower side of trapezoidal passage opening is higher than that of the pneumatic trough, the other side of the pneumatic trough is equipped with a triangular block which has constant section to the pneumatic trough, and a gas chamber is formed above the trapezoidal passage opening of the pneumatic trough. The merit of the invention is characterized in that it is beneficial for the growing of particle sludge, to decrease substantially the leak of minute particle sludge and improve the liquid stream in biochemical reaction field.

Description

Technical field [0001] The invention relates to an internal circulation (IC) anaerobic treatment equipment, in particular to a high-efficiency three-phase front-end processor for a cyclonic internal circulation (EIC) anaerobic reactor. Background technique [0002] Increasing the volumetric organic load and removal rate of anaerobic reactors and reducing the cost of reactors have always been the direction of scientific and technical personnel. On the basis of the second-generation representative process—upflow sludge-bed anaerobic reactor (UASB), the third-generation anaerobic reactor emerged. Their typical representatives are sludge expanded bed reactor (EGSB), internal circulation anaerobic reactor (IC), anaerobic baffled reactor (ABR). Although EGSB has the advantages of high volumetric organic load, it has the disadvantages of strict operation control, difficulty in designing reactor volume enlargement, lack of precision treatment and low removal rate, as well as the disadvan...
