specific Embodiment approach 1
[0010] Specific embodiment one: in this embodiment, the source water method for pretreatment of high ammonia nitrogen, high organic matter and manganese compound pollution is realized through the following steps:
[0011] 1. Add permanganate compound agent PPC to the source water for chemical pre-oxidation. The chemical pre-oxidation time is 20-30 minutes. Among them, the dosage of permanganate compound agent PPC is 0.6-0.8 mg / L. The water source The water temperature is 20-30°C, the pH value is 7.1-7.6, the turbidity is 15.2-83.3NTU, the ammonia nitrogen concentration is 0.70-4.25mg / L and the permanganate index concentration is 4.40-7.80mg / L, the total manganese The concentration is 0.16~1.13mg / L;
[0012] 2. Pass the source water after chemical pre-oxidation treatment into the biological aerated filter for treatment. The process parameters of the biological aerated filter process: use volcanic rock as the filler of the biological aerated filter, and the particle size of the ...
specific Embodiment approach 2
[0015] Embodiment 2: This embodiment differs from Embodiment 1 in that: the dosage of the permanganate compound agent PPC in Step 1 is 0.65-0.75 mg / L. Other steps and parameters are the same as the specific way one.
specific Embodiment approach 3
[0016] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the dosage of the permanganate compound agent PPC in Step 1 is 0.70 mg / L. Other steps and parameters are the same as in the first embodiment.
