Compared with other activated carbon products, the main feature of powdered activated carbon application is that the investment in technology is less, the effect is obvious, and the running cost is low. However, how to effectively and effectively exert the effect of powdered activated carbon to remove pollution, there are still many problems worth studying. The following focuses on the problems that powdered activated carbon should solve in engineering applications.
1. The problem of accurately preparing and quantifying the addition of powdered activated carbon in the application: In order to stabilize the effect of adsorption and decontamination of powdered activated carbon, the accuracy of dosing and measurement should be ensured within a certain range, which is not only related to the treatment effect, but also the cost of water production. closely related. The entire powdered activated carbon storage, formulation, dosing equipment or system constructed according to the appropriate parameters must be able to prevent the instability factors caused in various links, such as the blockage problem during the transportation and dosing process, which will cause the flow to be unstable. Thereby affecting the effect of decontamination.
2, investment, cost control: the most critical issue of the application of powdered activated carbon technology is investment and cost control, in order to meet the new "Sanitary Standards for Drinking Water" (mainly CODMn <3 mg / L, in special cases not more than 5 Mg/L), most water divisions are facing technical problems. For most water divisions, water pollution is generally intermittent or sudden, and conventional processes are able to meet new specifications most of the time, so powdered activated carbon technology is a very practical technology. The investment is relatively provincial, the cost is low, and the investment is flexible.
3. Automatic control of equipment or system: To further reduce the operating strength of powdered activated carbon dosing equipment, how to achieve automatic operation, match with the original automatic control system of the water plant and how to automatically track and adjust according to the change of water quality to meet the stable effluent quality The purpose of this is also a key factor that constrains the application of this technology.
4. The problem of dust pollution in the application: In the application of the water plant, the powdered activated carbon is in a lot of links, such as loading, unloading, unpacking, compounding and adding, and the labor intensity is high, which easily causes dust to fly, resulting in a bad working environment. The strong resistance of people has become a key and substantial problem that restricts the application of powdered activated carbon technology. In summary, you can do it, and use the powdered activated carbon to remove pollution and use it more economically and effectively.
