Embodiment 1
[0015] Example 1 The method of the present invention was used to treat high-concentration nitrogen-containing wastewater discharged from a cold rolling section of a steel plant.
[0016] (1) The waste water discharged from the cold rolling section of a steel plant is introduced into the regulating tank, and the average concentration of total nitrogen in the incoming water is 600 mg / L, the average concentration of COD is 40 mg / L, and the pH is between 6-9.
[0017] (2) Introduce nitrogen-containing wastewater into the CMBR reaction tank, the dosage of methanol is 1600mg / L, the dosage of potassium dihydrogen phosphate is 24mg / L; the denitrification rate is 0.06kgNO3-N∕(kgMLSS·d); sludge load 15g / L; there is a submersible mixer in the tank for mixing and mixing, with a residence time of 16h;
[0018] (3) Introduce the mixed liquid discharged from the CMBR reaction tank into the sludge separator. In this embodiment, the activated sludge separator is a vibrating membrane separator, using ...
