Example Embodiment
[0034] Example 1
[0035] Take the coking wastewater after ammonia distillation and degreasing treatment as raw material water to be treated, with a water volume of 100m 3 / h, the water quality of coking wastewater is shown in Table 1:
[0036] Table 1
[0037] Item
[0038] The coking wastewater first enters the anaerobic reactor together with the return sludge from the sedimentation tank. Its main function is to release phosphorus and at the same time ammonify part of the organic matter; the effluent from the anaerobic reactor enters the anoxic reactor for denitrification treatment. The nitrate nitrogen is sent from the aerobic reactor through the internal circulation; the wastewater after denitrification is introduced into the aerobic reactor, where COD / BOD removal, nitrification and phosphorus absorption are carried out, and a part of the mixture is returned to anoxic Reactor: The effluent after aerobic reaction is introduced into the sedimentation tank for sludge-water separ...
