Embodiment 1
[0021] Such as figure 1 Shown, a kind of reflux part uses denitrification anaerobic ammonium oxidation sewage advanced treatment process, comprises the following steps:
[0022] S1. Preliminary purification of sewage. First, the temperature of the returned part of the sewage is raised to 25°C and kept warm, and anaerobic bacteria are added to the heated sewage, and incubated at a constant temperature for 1 hour before being used;
[0023] S2, preparation treatment, inoculate the nitrifying bacteria into the 10-day sludge age sludge with a water content of 70%, and then cultivate it at a constant temperature of 25°C for 1-3 days and store it at a constant temperature for later use;
[0024] S3, material mixing, add the sludge prepared in step S2 and the sewage prepared in step S1 together into the mixing reactor, and ultrasonically mix the sludge and sewage in the mixing reactor without stirring, and the prepared sludge concentration is 2000mg / L The mud-water mixture, then the...
Embodiment 2
[0032] A sewage advanced treatment process using denitrification anaerobic ammonium oxidation in the reflux part, comprising the following steps:
[0033] S1, preliminary purification of sewage. Firstly, the temperature of the returned part of the sewage is raised to 40°C and kept warm, and anaerobic bacteria are added to the heated sewage, and incubated at a constant temperature for 6 hours before being used;
[0034] S2, preparation treatment, inoculate the nitrifying bacteria into the 50-day sludge age sludge with a water content of 80%, and then cultivate it at a constant temperature of 40°C for 3 days and store it at a constant temperature for later use;
[0035]S3, material mixing, add the sludge prepared in step S2 and the sewage prepared in step S1 together into the mixing reactor, and ultrasonically mix the sludge and sewage in the mixing reactor without stirring, and the prepared sludge concentration is 3000mg / L The mud-water mixture, then the mud-water mixture is ad...
Embodiment 3
[0043] A sewage advanced treatment process using denitrification anaerobic ammonium oxidation in the reflux part, comprising the following steps:
[0044] S1. Preliminary purification of sewage. First, the temperature of the returning part of the sewage is raised to 30°C and kept warm, and the pH value of the returning part of the sewage is adjusted to 7. Then, anaerobic bacteria are added to the heated sewage, and incubated at a constant temperature for 3 hours before use. , and the amount of anaerobic bacteria used is 600 g / m 3 ;
[0045] S2, preparation treatment, inoculate the nitrifying bacteria into the 20-day sludge age sludge with a water content of 85%, and then cultivate it at a constant temperature of 30°C for 2 days and store it at a constant temperature for later use;
[0046] S3, material mixing, add the sludge prepared in step S2 and the sewage prepared in step S1 together into the mixing reactor, and ultrasonically mix the sludge and sewage in the mixing react...
