Thank you for the parameters. I would increase MLSS. DO is good, so I think you just need more bugs to get the treatment you want. That said, there are things that can inhibit nitrification but I don't know them all off the top of my head. I would check nutrient levels and metals.
I run a plant that removes ammonia, warm weather MLSS can be as low as 2500, cold weather we increase to 4200. To combat M.Parvicella in the winter we also dose with PAX 14 from Kemira in winter.

1.the stripped sour water COD is about 500~800 ppm, the quantity is about 3,500 M3/D, the MLSS is about 2,500~3,500 ppm, I think the sludge system is all right.
2.the conductivity of stripped sour water is about 50 uS/cm, I think the water has little ions.
3.the phosphoric is added about 7 ppm, the N should be sufficient.
4.now we try to add other wastewater(domestic wastewater) to increase the nutrient and test in Lab preparatory.
