Abstract

PURPOSE: To provide treated water having a quality that allows reutilization or discharge to a stream by a method wherein an aqueous solution of a high molecular coagulant and a water-soluble inorganic salt of Ca, etc. is added to the muddy water and the separated water is added with a water soluble salt of Al, etc.
CONSTITUTION: The muddy water developed in a civil engineering or building work is mixed with an aqueous solution of a high molecular coagulant such as polyacryloamide and a water soluble inorganic salt such as that of Ca or Mg. This causes flock and separated water. The separated water is added with a water- soluble inorganic salt of either Al or Fe (III). This forms the remaining water- soluble component and insoluble substance, and the ability of coagulation is lost. Thus, the treated water is provided with a quality that allows reutilization or discharge to a stream.
