LIQUID NUTRIENT COMPOSITION CONTAINING TRACE ELEMENT FOR BIOLOGICAL WASTEWATER TREATMENT AND WASTEWATER TREATMENT METHOD USING THE SAME

摘要

PURPOSE: A liquid nutrient composition containing a trace element is provided, which is characterized in that the medicine is including elements which are necessary for development of microorganism like magnesium, calcium, iron, manganese, aluminum, copper, and cobalt. CONSTITUTION: In biological waste water treatment, small amount of inorganic elements are necessary for development of microorganism. The medicine is composed of several solutions. Calcium chloride, potassium chloride, and manganese chloride are dissolved for solution TM-A. Cobalt chloride, copper sulfate, and zinc chloride are dissolved for solution TM-B. Magnesium sulfate, iron sulfate, and aluminum sulfate are dissolved for solution TM-C. TM-A, TM-B, and TM-C solution is mixed in ratio of 100: 10: 1.
