dissolved sulfide

The results illuminate that the sulfide removal rate and the sulfur production rate can arrive at 100% and 73% respectively when the sulfide volume loading rate, dissolved oxygen and the sulfide influent concentration are optimal.

结果表明，在一定的硫化物容积负荷、溶解氧和进水硫化物浓度下，硫化物的去除率能达到100%，单质硫生成率能达到73%以上。
