The start-up performance of anaerobic ammonia oxidation reactors was investigated by inoculating with aerobic nitrifying sludge and autotrophic denitrifying sludge in two sets of anaerobic sequencing batch reactors(ASBR).

Nitrate nitrogen removal from ground water by autotrophic denitrification in a packed bed reactor;

The mechanisms and effects of ACF electrode were introduced in the aspects of treatment of refractory organics in water,synchronous enhanced autotrophic denitrification and other advanced treatment.

Results After having been acclimated in two stages, mixotrophic and autotrophic denitrification stages, the denitrifying bac.

Enhancing stability of denitrifying granular sludge by decreasing loading

To solve problems such as mutual adhesion and floating of denitrifying granular sludge when influent loads are high,the test of lowering influent temperature to stabilize granular sludge bed was performed.

Taking anaerobic nitrification sludge as inoculating sludge,the start-up of anammox reactor is adopted to treat the diluted piggery waste water,the ASBR reactor output water after 125 days operation showed the removal rates of NH4+-N,NO2——N for ASBR reached 91.

When the nitrification sludge was inoculated into the bioreactor in the fifth day, the ammonia removal rate was heightened from 5.

So,the treatment of the artificial wastewater by the heterotrophic nitrification aerobic granular sludge, which was developed from the heterotrophic nitrification microbial consortium,was studied.
