The invention relates to a composite microbial deodorant for treating household garbage and a preparation method of the deodorant. The composite microbial deodorant is prepared from raw materials as follows: 20-30 parts of composite photosynthetic bacterium powder, 10-20 parts of Bacillus subtilis powder, 20-40 parts of composite aspergillus powder and 30-50 parts of composite yeast powder. According to the composite microbial deodorant, hydrogen sulfide, ammonia as well as strains adapted to the household garbage are screened and degraded in a targeted manner, the composite microbial deodorant comprises beneficial microbes such as Thiocapsa roseopersicina capable of efficiently degrading the hydrogen sulfide, Rhodospirillum rubrum capable of efficiently degrading fatty acid series odors and the ammonia, Aspergillus oryzae rich in enzyme systems such as proteases, cellulose and the like, Bacillus subtilis capable of quickly degrading the ammonia, Rhizopus oryzae rich in lactic acid, Saccharomyces cerevisiae for producing ethyl alcohol, Candida guilliermondii rich in aroma-producing substances and the like, the beneficial microbes grow and breed in the household garbage and have the synergistic effect, the ecological environment of the household garbage is effectively improved, and emissions of the hydrogen sulfide, the ammonia and the fatty acid series odors are greatly decreased.

The invention discloses a three-level biological purification process for disposing terminal waste water from a sugar refinery; a primary treatment is carried out on waste water in an anaerobic organism tank; compound bacteria expanding propagation liquid comprising methane bacillus and anaerobic heterotrophic bacteria which mainly produces hydrogen bacillus is added according to one thousandth of capacity of water in the tank; the secondary treatment is carried out on waste water in an aerobic biological tank which comprises a multi-stage contact oxidation tank and an intensified micropore aeration tank, and compound bacteria expanding propagation liquid comprising rhodospirillum rubrum and colloidal bacillus is added according to one thousandth of capacity of water in the tank; and finally a three-level purification treatment is carried out on waste water in a water planting tank by smilacina atropurpurea. The process combines compound microbes and plants for three-level biological purification treatment on terminal waste water from the sugar refinery, not only leads treated water to completely reach the standard, but also leads purified discharged water to be totally recycled, at least saves water by more than 70%, and leads the removal rate of ammonia nitrogen, total nitrogen and total phosphorus to be more than 70% to 80%.
