we try to use the L tank sludge ,which is good for NH3-N ​​​reduction , and the mixed sludge(50% L sludge and 50% original M tank sludge ) is enhance the NH3-N ​​​reduction of the stripped sour water in the Lab. But in the plant , it is not easy to transport the sludge about 4000 M3 (MLSS) from L tank to M tank. we transport the L tank slugde about 1% per day to M tank , lasts about 2 month , but that cannot work. we think maybe some composition of water, such as cresol, affect the performance of L tank sludge, the 1% per day lasts 2 month cannot equivalent the 50% of L tank sludge.
