摘要

Disclosed are a wastewater pH adjusting method, a pH adjusting device, and a wastewater treatment system that can efficiently adjust the pH of wastewater with a simple configuration using peat moss. A pH adjuster 1 for causing rot fungi to act on peat moss 15 to produce humic acid, bringing waste water that is to be treated into contact with peat moss 15 and adjusting the pH of the waste water with the humic acid. The peat moss 15 possessed, the container 21 capable of storing the peat moss 15 in a wet and aerobic state, and the environment forming means for bringing the peat moss 15 stored in the container 21 into a wet and aerobic state, The environment forming means is a siphon 39 installed in the container 21, and the siphon 39 makes the inside of the container 21 full, thereby making the peat moss 15 wet and aerobic.
