3The thionizer cost is about 80,000), can reach higher degree of purification.But, the higher (15 yuan/kg (H of this method processing cost
2S) about), operation trouble (needing replacing or recycling desulfurizer once in per 4～6 months), and there is the secondary pollution problem in the depleted sweetening agent.
Compare with chemical method with the physics method, the biological process desulfurization has characteristics such as equipment is simple, cost is low, environment-protecting clean, recyclable elemental sulfur, is the desulfurization technology that has development potentiality.So-called biological desulphurization is exactly under suitable temperature, humidity, nutrition and oxygen supply condition, and the metabolism by thiobacterium is converted into elemental sulfur or sulfuric acid with hydrogen sulfide.Reaction process is:
H
2S+2O
2——H
