摘要: This study was aimed to explore the effect of elastic filler on pollutant removal in each compartment anaerobic baffled reactor (ABR), ABR with filler, and without were compared. The result showed that increased rate chemical oxygen demand (COD) suspended solid (SS) first compartment, decreased COD SS second third compartments, had little fourth compartment. Elastic increase ammonia nitrogen compartments; nitrate nitrogen, nitrite total phosphorus ABR. In general, could improve but phosphorus. slightly concentration formic acid, acetic propionic butyric acid ABR, sum second, hird compartments. did not change composition dissolved organic matter (DOM)in changed kinds contents aromatic proteins, soluble microbial products humic acids they humicacids. degree DOM humification (or maturity) effluent, main source humus like substance effluent.
