Abstract

PURPOSE: To reduce the carriage of waste material by dehydrating mud which is obtained after the second treatment mud and the third treatment mud of the waste water containing organic compound are mixed in a specified proportion, frozen and melted.
CONSTITUTION: The waste water with organic compound content is separated into mud and liquid in the precipitation cistern 7 after digesting, oxidizing and biological treatments, the liquid is further separated into mud and liquid in the precipitation cistern 15 after chemical treatment. The second treatment mud from the precipitation cistern 7 and the third treatment mud from the precipitation cistern 15 are mixed in the mud mixer 20. The mix ratio is about 10% in a weight ratio of solid matter. After this, the mud is introduced in the freez-melt system dehydrator 18, the mud 21 is taken out after dehydration and the separated liquid produced when dehydrated is returned to the storing cistern 2.
