| Zusammenfassung: | The invention discloses a method for treating stainless steel pickling high-nitrate nitrogen wastewater, which comprises the following steps: selecting anaerobic flocculent sludge as inoculation sludge, and feeding the stainless steel pickling high-nitrate nitrogen wastewater into an up-flow denitrification device to domesticate the inoculation sludge to obtain stainless steel pickling high-nitrate nitrogen wastewater resistant sludge; adjusting the operation condition of the up-flow denitrification device, and culturing the flocculent sludge into granular sludge; after the granular sludge is formed, the water inflow of the stainless steel pickling high-nitrate nitrogen wastewater is increased for increasing the treatment load; the up-flow denitrification device is kept to operate under a high-load condition; the scheme has the characteristics of efficient and stable denitrification, less process flow and good purification effect.
