| 摘 要： | 试验研究表明,投加无机营养盐可强化剩余活性污泥好氧消化的效果.无机营养盐不仅提高了消化前期的污泥活性,加快了MLSS的降解速率,而且改善了污泥的沉降性能和过滤性能,并能使上清液COD值下降,硝化作用提前出现.

| Abstract: | The results of current experiments showed that the activity of bacteria in the aerobic digestion system of excess activated sludge could be increased at earlier stage of digestion by addition of inorganic nutrients. The added inorganic nutrients accelerated the degradation of MLSS, improved the settling and filter dewatering properties, decreased the supernatant liquor COD, and promoted the nitrification. |

| Keywords: | inorganic nutrient sludge aerobic digestion |
