Embodiment Construction
[0034] Such as figure 1 , figure 2 As shown, the process invention is composed of a pretreatment pool 1, a multiple redox environment coupled biological reaction pool (2, 3, 4, 5, 6, 7), and a filter cloth filter dynamic membrane biological reaction pool 8, which are sequentially connected together. The parts are connected into a whole. The pretreatment tank consists of a grille 10 and a grit chamber 18, and the two parts are integrated. A grit bucket is arranged at the lower part of the grit chamber, and the mud and sand are discharged through the mud and sand drainage pipe 11. The multi-redox environment coupled biological reaction pool includes anoxic zone 2, aerobic zone 3, anoxic zone 4, aerobic zone 6, anoxic zone 6, and aerobic zone 7, and the volume ratio of anoxic zone to aerobic zone is in order 1: 1.5: 1: 2.0: 1: 2.5, and the filler filling ratios in the anoxic zone and aeration zone are 40% and 90% respectively.
