Asked:
I would like to ask if the ratio of BOD and COD is 0.5, the process can also be set behind the hydrolysis of acid pool? Is not it necessary?
Answer:
Can not need, but also depends on your water concentration to set. Because the direct aerobic load can not be too high, aerobic water concentration generally COD1000mg / L the following line, if the load is too high aerobic no way, whether it is biochemical good is not good, plus a hydrolysis will be better.
