Abstract
The invention discloses a biochemistry tower which uses microbial method to process low density carbon bisulfide/ sulfureted hydrogen gas. The invention comprises multidimensional sphere filler and the desulfurizing bacteria. The character lies in: the gas passes through the filler, and drops the nutrient element such nitrogen and phosphor liquid onto the filler. The extravasate from the filler layer is neutralized and let out. The tower includes liquid cumulating plate, multidimensional sphere filler, air and liquid distributing device. The character lies in: the plate hasn't air dispersion cover, there's radial hole on the upper wall, there's taper cover on the barrel.

The specific embodiment:
Biochemical tower of the present invention, include tower body 1, its top is provided with waste gas inlet 2, below air inlet, be provided with distribution device 3, below distribution device, be provided with water-distributing device 5, the outer end of feed tube is connected with the recycle liquid pump of circulation liquid bath, water-distributing device in its other end and the tower body is communicated with, is fixed with drip tray 8 in the tower, and the cylindrical shell lower seal of diffusing gas cap 7 is connected in the hole uniform on the drip tray, the gas cap 7 that looses is a cylinder, be distributed with radial hole on the wall on tube top, the upper end of tube is provided with a tapered cap, and the diameter of shade is greater than barrel dliameter, gas-liquid is separated, and waste gas enters at the bottom of the tower through the cylinder of the gas cap that looses.Between liquid distributor and drip tray 8, be provided with many-sided ball filler 6, the tower body of drip tray top is provided with discharging tube 9, be attached with the bacteriophage group on the surface of filler, this bacteriophage can obtain by cultivating screening, and its method is that the pollution river silt that will contain microorganism species earlier is as cultivating body, in its nutrient solution, add sulphur at normal temperatures, with this understanding, bacteriophage is bred more and more, and other bacterial classifications are eliminated.
The big flow CS of microbiological treatment low concentration of the present invention
2And H
2The method of S is the low concentration CS that the viscose rayon workshop produces
2And H
2S waste gas, air inlet under the swabbing action of biochemical tower downdraft machine above biochemical tower enters the biochemical tower, distribution device is delivered to waste gas on the surface of the many-sided ball filler in the tower equably, contacts the CS in the waste gas with the liquid that adheres on the hole surface of filler body
2And H
2S is dissolved, above-mentioned liquid phase kind, the CS in the liquid phase are arrived in emulsification
2And H
2S is absorbed by bacteriophage, is broken down into SO in the body of bacteriophage
