Embodiment 1
[0114] Take the anaerobic digested sludge dehydrated liquid of a municipal sewage treatment plant as the system inlet water, the water volume is 2500m 3 / d, average pH 7.9, average water temperature 32℃, average influent COD concentration 1131mg / L, BOD 5 The average concentration of 952mg / L, the average concentration of ammonia nitrogen 550mg / L, the average concentration of nitrous and nitrate nitrogen 2.0mg / L, the average alkalinity (in CaCO 3 Count) 3795mg / L, total effective volume of reaction tank 800m 3 , The effective volume of denitrification tank is 400m 3 , The inlet water enters the four reaction tanks C1-C4 through the denitrification tank.
[0115] Preparation for start-up. Suspended carrier is added to each reaction tank and denitrification tank. The effective specific surface area of the carrier is 800m. 2 / m 3 , The void ratio is 90%, in line with the industry standard of "High-density polyethylene suspended carrier for water treatment" (CJ / T461-2014), the filling ra...
Embodiment 2
[0124] Take the anaerobic digestion effluent of a landfill plant’s landfill leachate as feed water, with a water volume of 1300m 3 / d, pH 7.8-8.3, average water temperature 33℃, average influent COD concentration 920mg / L, BOD 5 The average concentration is 801mg / L, the average ammonia nitrogen concentration is 550mg / L, and the total effective volume of the reaction tank is 400m 3 , Divided into four reaction tanks, each with an effective volume of 100m 3 , The effective volume of denitrification tank is 200m 3 , The inlet water enters the four reaction tanks C1-C4 after passing through the denitrification tank.
[0125] Start-up preparation. Suspended carrier is added to the reaction tank and denitrification tank, and the effective specific surface area of the carrier is 800m 2 / m 3 , The void ratio is 90%, in line with the industry standard of "High-density polyethylene suspended carrier for water treatment" (CJ / T461-2014), the filling rate is 50%; the aerobic sludge is inoculate...
