Physical adsorption of activated carbon

At this time, the concentration of the adsorbed substance in the solution is called equilibrium concentration.In aerobic part, a self-made internal circulating biological fluidized bed reactor was used to treat organic pesticide wastewaterThe effects of internal circulating biological fluidized bed on the removal of organic matter and the deamination of organic pesticide wastewater, the change of wastewater biodegradability and acute biological toxicity were investigated.The results show that the internal circulation biological fluidized bed with granular activated carbon as the carrier has a fast speed of membrane and can be cultured in about days by the rapid sludge drainage methodOut of activated sludge.The internal circulating biological fluidized bed with granular activated carbon as the carrier is not sensitive to temperature change at 1 ℃, and has a certain impact resistance ability.Aeration amount has effect on the treatmentToo large or too small aeration will reduce the reactor treatment efficiency.The optimal hydraulic retention time of the internal circulating biological fluidized bed using granular activated carbon as carrier is, and the treatment effect will be affected if the hydraulic retention time is too long or too short.granular activated carbon coconut shell

At the aeration rate of /,During hydraulic retention, the total helium removal rate is.%,.%, water effluent/up tothe biodegradability of wastewater was significantly improved, and the acute biological toxicity was reduced by %.When the efficiency of internal circulating activated carbon biological fluidized bed treatment is.%, the reaction is obtainedwww.wyactivatedcarbon.com 

When the radon adsorption coefficient of activated carbon is constant,n is proportional to the concentration of radon. In this case, Equation (10) represents the functional relationship among the total number of activated carbon V, radon concentration and adsorption (or exposure) time. Therefore, the concentration of radon in the environment can be calculated according to the total number of activated carbon and adsorption time.Simulation calculation and result analysis of total number of activated carbon According to Equations (5) and (10), a computer program can be written to calculate the relationship between the total number of Y in the process of radon adsorption on activated carbon and the relationship between the total number of Y after the removal of activated carbon and the change of time.

In order to verify the accuracy of the simulation calculation, two 12g activated carbon bags thickness of activated carbon ~ 1.5cm) were put into the container containing uranium ore, and then taken out after radon adsorption for 30 min and 85 min. After continuous measurement, the change curve of total Y number of activated carbon over time could be obtained.

According to the adsorption duration used in the experiment and the appropriate value of n (in the calculation process, when the adsorption duration is 30 min, n=480
