NOVELTY - Taking pine needles of Pinus tabulaeformis as biological filler for biologically deodorizing in sewage process involves collecting and arranging pine needles of Pinus tabulaeformis; matching with hollow plastic balls, and filling using filler support and glass steel mold to form grids; collecting strain; injecting surplus mud to humidifying and medicating box of deodorizing system; inoculating and spraying; and finishing microorganism inoculation.    USE - Method for taking pine needles of Pinus tabulaeformis as biological filler for biologically deodorizing in sewage process (claimed).    ADVANTAGE - The biological filler supplies nutrient material and microelement for growth of microorganism. It has long living life and no peculiar smell. It does not block during long-term operation process. It has good over-current property and transferring property. It is made of cheap material that can be obtained easily.    DETAILED DESCRIPTION - Taking pine needles of Pinus tabulaeformis as biological filler for biologically deodorizing in sewage process involves: (A) collecting and arranging pine needles of Pinus tabulaeformis; (B) matching with hollow plastic balls, and then filing them: using filler support and glass steel mold to form grids; (C) collecting strain by collecting residue activated sludge into barrels by tannery sewage process second-settling pool, and transporting barrels to deodorizing site; (D) injecting residue activated sludge to humidifying and medicating box of deodorizing system, adding tap water to dilute to mixed liquor suspended solids of 1000 mg/L according to its mud concentration; (E) hoisting by humidifying pump, spraying water to filler from top part of filtering pool and carrying out microorganism inoculation by QB3 type solid cone sprayer, simultaneously starting ozone collecting pressurizing system, processing ozone by washing tower, pre-treating and making ozone pass through filler layer from lower to the upper part; (F) inoculating and spraying for 8 hours period, inoculating and spraying for 30 minutes in every period, and making ozone continuously pass through the filler layer; (G) finishing microorganism inoculation by observing needles long bacteria state, concentration of inlet and outlet ozone hydrogen sulfide with microscope, spraying for 5-7 days, processing ozone by the filtering pool, adjusting parameters of humidity, temperature, pressure, washing water and pH, continuously domesticating and increasing bacteria for 15-20 days, making system operate stably to reach preset purifying effect, and making system modulate. The filling step involves aperture of grid: 25 mm x 25 mm; standard of pine needles of Pinus tabulaeformis: phi =1.5 mm, L=100-150 mm; standard of hollow plastic ball: phi =50 mm; filing height: 1 m; filling mode: filling pine needles of Pinus tabulaeformis and hollow plastic balls by different layers; plastic balls on the first layer: H=50 mm; puff pine needles on the second layer: H=200 mm; plastic balls on the third layer: H=50 mm; puff pine needles on the fourth layer: H=200 mm; plastic balls on the fifth layer: H=50 mm; puff pine needles on the sixth layer: H=200 mm; plastic balls on the seven layer: H=50 mm; and puff pine needles on the eight layer: H=200 mm.
