WASTE WATER TREATMENT METHOD USING BITTERN AND CHEMICALS

摘要

PURPOSE: A wastewater processing method using brine and chemicals is provided to improve the processing efficiency of ammonia nitrogen and phosphorus inside wastewater. CONSTITUTION: A wastewater processing method using brine and chemicals comprises the following steps: inserting the brine and more than one chemical selected from the group consisting of MgCl2·6H2O, MgSO4·7H2O, MgO, and Mg(OH)2 to wastewater, during the struvite crystallization reaction of the non-biodegradable industrial wastewater containing high concentration of ammonia nitrogen and phosphorus; and stirring the mixture to process and precipitate the ammonia nitrogen and the phosphorus.
