FENTON-ZEOLITE WASTEWATER TREATMENT SYSTEM FOR PRIMARILY REMOVING CONTAMINANTS BY CHEMICAL COAGULATION AND PRECIPITATION AND INCREASING REMOVAL EFFICIENCY OF CONTAMINANTS BY FENTON OXIDATION PROCESS AND ZEOLITE ADSORPTION PROCESS

摘要

PURPOSE: To provide a noble livestock wastewater treatment system for obtaining stabilized effluent satisfying effluent quality standard, reusing treated water and minimizing pollutant loading flown in the water quality environment by developing a livestock wastewater treatment method comprising coagulating and precipitating steps, a plural fenton oxidation processes and zeolite adsorption process. CONSTITUTION: The livestock wastewater treatment system comprises a coagulation reactor for eliminating organic matters using ferric chloride (FeCl3); a coagulation precipitating tank for removing the precipitated coagulated material by precipitating a coagulated material; four fenton oxidation reactors comprising pH adjusting tank, reactor and precipitation tank; and a zeolite adsorption reactor filled with zeolite, wherein the zeolite adsorption reactor is manufactured by filling a reactor with clinoptilolite ((Ca1Na2(Al2Si7O18)6H2O)) type zeolite as a natural zeolite.
