Embodiment 1
[0046] Method embodiment 1, an aerobic granular sludge integrated sewage treatment method, including activated sludge inoculation before operation, cultivation of dominant bacteria and continuous operation treatment;
[0047] First, the inoculation of activated sludge and the cultivation of dominant bacteria before operation
[0048] Before the continuous operation of the biochemical device, the activated sludge inoculation and the cultivation of dominant strains were completed, and ammonia oxidizing bacteria and denitrifying phosphorus accumulating bacteria (DPAO) were used for double sludge short-cut nitrification s ) is the dominant strain, and the aeration volume of the reactor is controlled at 0.21m during the cultivation period 3 / h; use high-load inoculation cultivation, suffocate for 36 hours, then continuously enter water and aerate continuously. When the MLSS in the pool is close to about 3.5g / L and the sludge index SVI is about 90, the sedimentation ratio SV is 28%....
Embodiment 2
[0051] Method embodiment 2, the first, the cultivation of activated sludge inoculation and dominant bacterial species before operation
[0052] Before the continuous operation of the biochemical device, the activated sludge inoculation and the cultivation of dominant strains were completed, and ammonia oxidizing bacteria and denitrifying phosphorus accumulating bacteria (DPAO) were used for double sludge short-cut nitrification s ) is the dominant strain, and the aeration volume of the reactor is controlled at 0.21m during the cultivation period 3 / h; use high-load inoculation cultivation, suffocate for 48 hours, then continuously enter water and aerate continuously. When the MLSS in the pool is close to about 4.0g / L and the sludge index SVI is about 80, the sedimentation ratio SV is 26%. That is, the cultivation is successful;
[0053] Second, the continuous operation process is the same as in Example 1.
