| Abstract: | By using magnesium salt as settling agent and increasing solution pH by CO2 degasification,nitrogen and phosphorous in swine wastewater were removed as struvite precipitate,and the removal rate of ammonia-nitrogen was improved by natural clinoptilolite adsorption.Effects of zeolite dosage,magnesium salt dosage,aeration time,initial solution pH on phosphate and ammonia removal were investigated.Experimental results indicated that under the optimal reaction condition of zeolite dosage 0.5 g/L,Mg/P molar rate ... |
