With the rapid development of social economy and the further acceleration of industrialization, a large number of gaseous pollutants (mainly organic or inorganic substances containing paint, sulfur, nitrogen and oxygen) are produced in the industrial process, forming industrial waste gas.

未经处理的工业废气排放到大气中，会严重污染环境并影响附近居民的生活质量。例如，会使人感到不适，出现头痛、头昏、恶心、呕吐、食欲不振和精神不集中等症状。另外，对人的呼吸系统、循环系统、消化系统和生殖系统也有影响。

Untreated industrial waste gas discharged into the atmosphere will seriously pollute the environment and affect the quality of life of nearby residents. For example, it can make people feel unwell, with symptoms such as headache, dizziness, nausea, vomiting, loss of appetite and lack of concentration. In addition, it also affects people's respiratory system, circulatory system, digestive system and reproductive system.

世界各国对生物脱硫都非常重视，已开发了数十种行之有效的脱硫技术，其中广泛采用的烟气脱硫技术有：石灰/石灰石—石膏湿法，具有适用煤种宽、原料廉价易得、脱硫率高（可达90％以上）等诸多优点，占据最大的市场份额，但投资和运行费用大，运行维护量大。

Countries all over the world attach great importance to biological desulfurization and have developed dozens of effective desulfurization technologies. Among them, the widely used flue gas desulfurization technology is lime / limestone gypsum wet method, which has many advantages, such as wide application of coal, cheap and easy availability of raw materials, high desulfurization rate (up to more than 90%), and occupies the largest market share, but the investment and operation cost are large, Large amount of operation and maintenance.

脱硫催化剂的优点可以提高脱硫效率，无需进行设备扩容改造；节能降耗（省厂用电）；减少石灰石用量；提高燃煤调整和脱硫运行、备用的灵活性；增加石灰石的分散性，减少设备的结垢；提高氧化效率，减少亚硫酸根含量，提高真空皮带机脱水效率等。

The advantages of desulfurization catalyst can improve desulfurization efficiency without equipment capacity expansion and transformation; Energy saving and consumption reduction (saving auxiliary power); Reduce limestone consumption; Improve the flexibility of coal adjustment and desulfurization operation and standby; Increase the dispersion of limestone and reduce the scaling of equipment; Improve oxidation efficiency, reduce sulfite content and improve dehydration efficiency of vacuum belt conveyor.

脱硫催化剂在工业中的用途有很多种，特别是对于现在的工业来说基本上都离不开它，而在锅炉烟气的处理中使用脱硫催化剂可以给我们的工业制造带来很多方便。SO2污染已超过烟尘污染成为大气环境的第一大污染物。

Desulfurization catalyst has many uses in industry, especially for the current industry, which is basically inseparable from it. The use of desulfurization catalyst in the treatment of boiler flue gas can bring a lot of convenience to our industrial manufacturing. SO2 pollution has exceeded soot pollution and become the largest pollutant in the atmospheric environment.

随着世界各国工业化进程的不断加深，生物脱硫有别于其他脱硫方式是世界上唯一大规模商业化应用的脱硫方法，是控制酸雨和SO2污染的最为有效的和主要的技术手段。

With the deepening of industrialization in the world, biological desulfurization is different from other desulfurization methods. It is the only large-scale commercial desulfurization method in the world. It is the most effective and main technical means to control acid rain and SO2 pollution.
