Abstract:
Zeolite and coal cinder were took as main substrates to construct micro-ecological filter to remedy landscaping water. Screening and domesticating dominant consortium to intensify remedying process, aboriginal colony and naked substrate was contrast. It was showed that, removal efficiency of NH4(+) -N, TN, and TP by and dominant colony increased with rest time. Removal efficiency of NH4(+) -N by naked system was the highest, then dominant consortium system. Removal efficiency of TN by dominant consortium system was the highest and increased evidently with rest time. TP removal by aboriginal colony system was the best. NO2(-) -N in naked system was the lowest, which in dominant consortium system was lower than aboriginal system. TN concentration along hydraulic distance kept falling in dominant colony system; TP concentration along hydraulic distance in aboriginal system kept the lowest. Abundant nitrous and nitride bacterium in dominant colony made nitrification swift and thoroughly, cut accumulation of middle production and hasten nitrogen removal. Dominant consortium kept high activity in long time, which intensified removal of nitrogenous contamination. Cooperation of multi-colony enhanced P removal capacity of system.
