Title:
REACTION APPARATUS FOR SIMULTANEOUS DENITRIFICATION AND DEPHOSPHORIZATION WITH TWO-SLUDGE AND BIOFILM PROCESSES
Document Type and Number:
WIPO Patent Application WO/2011/050639
Kind Code:
A1
Abstract:
A reaction apparatus for simultaneously denitrifying and dephosphorizing with two-sludge and biofilm processes is provided, which comprises a 1# sequencing batch reactor (2), a 2# sequencing batch reactor (5) and a nitrate exchanger (9). The 1# sequencing batch reactor (2) is connected to a first intake pump (1) by a pipeline, and also connected to the nitrate exchanger (9) by a pipeline. The nitrate exchanger (9) is connected to the 1# sequencing batch reactor (2) via a third intake pump (7), and connected to the 2# sequencing batch reactor (5) via a second intake pump (4). In addition, the 2# sequencing batch reactor (5) is also connected to the nitrate exchanger (9) by a pipeline. An activated sludge process and biofilm process are combined and used in the apparatus, such that the contradiction between denitrification and dephosphorization in conventional process is solved.
