3. The fluctuation of water quality and water quantity is large.
4. Contains partial high impedance substances such as amyl alcohol, and has long biological carryover time.
5. Contains nitrogen and phosphorus, but is deficient in nitrogen and phosphorus nutrients due to the high organic carbon content.
6. Does not contain toxic and harmful substances.
