Study on packing biofilm and process conditions of hydrogen sulfide and ammonia removal by composite biofilter;

Study on deodorization of municipal solid wastes by a composite biofilter;

The composite biofilter process(a combination of biotrickling filter and biofilter),taking clinoptilolite and wood chip as the media,was applied to treat the mixed odors(H_2S and NH_3).

Study on hydrogen sulfide and ammonia odors treatment by the combined bio-filter;

In this paper,it has been reported technique to treat the odors mixed with H_2S and NH_3 by use of a novel combined bio-filter,witch is a patent in which biofilter is combined with a bio-trickling and a bio-filtering pond.

The combined biological aerated filter(CBAF) was used to enhance nitrogen removal from secondary effluent of a WWTP in Shenzhen.

In order to reasonably determine the thickness of biological aerated filter bed,using the secondary effluent from a WWTP in Shenzhen City as raw wastewater,the variation of pollutants concentration along the depth of combined biological aerated filter was studied.

Utilizing a combined velocity-variable biofilter,a full-scale experiment was carried out on advanced treatment of secondary effluent from an oxidation ditch wastewater plant.

Multiple Layer Microbial-Earthworm Eco-filter System (MMEEF) with combination of microbe and earthworm is a representative of micro-fauna to form artificial ecosystem and is a new wastewater treatment technique to degrade pollutants for sewage treatment.
