The results show that the adsorption isotherms of Zn2' and Cd by modified activated carbon are in good agreement with the Langmuir and Freundlich adsorption models.
By fitting the kinetic equation of Zn2 adsorption with modified activated carbon, it was found that the first 30min of the adsorption reaction was in line with the Lagergren quasi-first-order reaction, and the second order reaction was in line with the latter.
The adsorption of Cd by modified activated carbon was a Lagergren quasi-first order reaction in the first 20 minutes.
The reaction after adsorption for 20min belongs to the Lagergren quasi-second order reaction.Information on how to identify strategic and tactical negotiation levels that will help achieve the best prices.

Methods to help engage with the right suppliers and discover KPI's to evaluate incumbent suppliers.1. The humidification outside the tower is only 5% higher than the humidification and cooling inside the tower, but the humidification outside the tower has the advantages of simplifying the system process, reducing investment, and reducing the wall sticking inside the tower.
2. Activated carbon has a certain effect on the removal of nitrogen oxides. In the test, the high concentration of SOZ in the flue gas affected the removal of NO by activated carbon, and the measured removal rate was about 10%.
3. The removal rate of HCl by activated carbon is up to 50%, but the removal effect of acid gas H and SO3 is not obvious.
In the test, the desulfurization effect of the cloth bag dust remover was tested, and its desulfurization rate was about 9%.
4. Analyze the reasons for the low SOZ and NO removal efficiency of activated carbon in the test :(1) ordinary activated carbon is used in the test, which has a low adsorption performance;
(2) Due to the limited test conditions, the low input amount of activated carbon per hour in the test means the selected ACIS is lower.
Although the removal efficiency of the activated carbon on SO2 and NO measured in this test is low, the activated carbon used in circulating fluidized bed flue gas desulfurization and denitration has the advantages of simple and reliable process, low system resistance, stable desulfurization and denitration, good economic and environmental protection, NO secondary pollution and so on.
