【澳门皇冠金沙网站】的运用能耗少、去除率高,但是【澳门皇冠金沙网站】也有自己的局限性,就是需给硫细菌营造一个适合的环境,才干确保其具有较高的生物活性,以到达一个好的脱硫效果。
The application of biological desulfurization has less energy consumption and high removal rate, but biological desulfurization also has its own limitations. It is necessary to create a suitable environment for sulfur bacteria to ensure their high biological activity in order to achieve a good desulfurization effect.
1、pH值的控制。将脱硫循环水的pH值维持在2~3之间,到达较好的脱硫效果,当pH值发生较大变化时,硫细菌的活性急剧降落以至失去活性,如本工程中当pH值由2~3调整到5~7时,【澳门皇冠金沙网站】塔简直完整失去了脱硫效果。所以在【澳门皇冠金沙网站】中,维持稳定的pH值是至关重要的,它将直接影响脱硫效果的好坏。
1. Control of pH value. When the pH value of desulfurization circulating water is maintained between 2 and 3, a better desulfurization effect can be achieved. When the pH value changes greatly, the activity of sulfur bacteria drops sharply and even loses its activity. For example, when the pH value is adjusted from 2 to 3 to 5 to 7 in this project, the biological desulfurization tower almost completely loses its desulfurization effect. Therefore, in biological desulfurization, it is very important to maintain a stable pH value, which will directly affect the quality of desulfurization effect.

2、DO浓度的控制。气箱中H2S和O2难以发作反响,【澳门皇冠金沙网站】反响过程主要发作在液相中,所以脱硫塔内循环喷淋水中的DO(溶解氧)浓度是影响【澳门皇冠金沙网站】的一个重要要素。
2. Control of DO concentration. The reactions of H2S and O2 in the gas tank are difficult to occur, and the reactions of biological desulfurization mainly occur in the liquid phase. Therefore, the concentration of DO (dissolved oxygen) in the circulating spray water in the desulfurization tower is an important factor affecting biological desulfurization.
3、H2S负荷的控制。实践工程运转发现,在硫细菌所能接受范围内,H2S容积负荷越高,微【澳门皇冠金沙网站】反响越能坚持良好的运转效果,且不易发作循环水急剧酸化的现象。
3. Control of H2S load. Practical engineering operation found that within the acceptable range of sulfur bacteria, the higher the volume load of H2S, the better the microbial desulfurization response can adhere to the good operation effect, and it is not easy to occur the phenomenon of rapid acidification of circulating water.
