WATER-TREATING FINE-GRANULAR POWDER CONTAINING MAGNETITE POWDER AND ORGANIC ADSORBENT AND PROCESS FOR WATER-TREATING BY USING THEREOF

摘要

PURPOSE: Provided are a water-treating fine granular powder containing a magnetite powder, which increases an adsorption efficiency of eutrophication materials such as NH4¬+, NO3¬-, PO4¬3- and SOx, water-soluble organic compounds and environmental harmful materials and is able to separate floating materials within a relatively short time, and an organic adsorbent and a process for water-treating by using thereof. CONSTITUTION: The water-treating fine granular powder comprises an activated carbon or an activated carbon fiber, 1.0-20 wt.% of a Cu catalyst, 5.0-50 wt.% of a magnetic substance of a magnetite and 1-15 wt.% of calcium hydroxide regarding method for preparing an ultra-high speed water-treating fine-granular powder and has a size of 0.1-5.0 millimeters. The water-treating process comprises a step of separating the fine granular powder adsorbing eutrophication materials such as NOx, PO4 and SOx and water-soluble organic compounds in a water-treating tank or a bath by applying magnetic force thereto.
