|
摘要
以模拟城市生活污水为处理对象,采用反硝化除磷产电工艺,研究了不同的超越污泥比和含磷污泥回流比对系统脱氮除磷及产电的影响。当超越污泥比和含磷污泥回流比相等且分别为0.30、 0.35和0.40时,反硝化除磷产电系统出水COD平均质量浓度分别为11.16、 8.78和12.08 mg/L,出水氨氮平均质量浓度分别为1.95、4.74和5.85 mg/L;出水PO43--P平均质量浓度分别为1.38、 0.67和1.93 mg/L,反硝化除磷产电系统的开路电压和最大功率密度分别为0.601 V和62.42 mW/m2、 0.624 V和53.01 mW/m2、 0.608 V和51.12 mW/m2。当超越污泥比和含磷污泥回流比为0.35时,反硝化除磷产电系统去除污染物和产电的效果最好。
Taking stimulant municipal domestic sewage as the object, using denitrifying phosphorus removal and electrogenesis as the treatment process, the influence of exceeding sludge ratio and phosphorus-containing sludge reflux ratio on nitrogen and phosphorus removal as well as electrogenesis were studied. Under the condition that the exceeding sludge ratio equaled to the recycled phosphorus-containing sludge ratio, which were0.30, 0.35 and 0.40 respectively, the average mass concentrations of COD in effluent water from denitrifying phosphorus removal and electrogenesis system were 11.16, 8.78 and 12.08 mg/L respectively, the average effluent mass concentrations of ammonia nitrogen were 1.95, 4.74 and 5.85 mg/L respectively; the average effluent mass concentrations of PO43-were 1.38, 0.67 and 1.93 mg/L respectively. The open circuit voltage and the maximum power density of the said system were 0.601 V and 62.42 mW/m2, 0.624 V and 53.01 mW/m2, 0.608 V and 51.12 m W/m2 respectively. When the exceeding sludge ratio and phosphorus containing sludge reflux ratio were both0.35, best pollutants removal and electrogenesis effect could be obtained.
