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.

Through monitoring and analyzing the data of NH~+_4-N and NO~-_2-N, as well as observing the sludge color change, we have found that, with the aerobic nitrifying sludge taken as inoculum, the anammox ASBR can be started up within 142 d.

This paper is aimed at introducing the difference of two kinds of anammox sludge cultivated with aerobic nitrifying sludge and anaerobic granular sludge as inoculum.

Applying factorial experiments to study the toxicity effects of heavy metal mixture on nitrifying granules;

The nitrification inhibition by substrate and it’s kinetic model in nitrifying granules were investigated by using a batch respirometry test.

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).
