The sewage sludge is the secondary product of waste water treatment process. There is a lot of sewage sludge produced everyday. The sewage sludge contains the combustible matter, especially the biochemical sludge, which contains a lot of activated sludge bacteria and combustible matter. According to the experiment, calorific value of the sewage sludge can reach 2200-2300 calories/T. And in summer the calorific is lower than that in winter. t is reported that till Feb, 2009, there was 105 T sewage sludge produced in China everyday, and this number keeps increasing. So investing in a charcoal machine is necessary. The carbonization plant is a new trend in dealing with the sludge.
The carbon we get from the carbonized sewage sludge contains 2000 calories per kilogram, so this kind of carbon is a useful energy, and if we reprocess it, we can get energy while recycle the sewage sludge. The carbon can be the material of molding briquette, in addition, it can also be the special fertilizer for vegetable.
Definition of Sewage Sludge Carbonization
The sewage sludge carbonization means that through the high temperature, the biochemical sludge will experience the biomass pyrolysis process, and the moisture will be released, but the carbon content of the sludge can be saved. After this process, we can get the carbon from the sewage sludge, and the carbon is granular, which is similar to the industrial carbon particles. This also explains the working process of biomass pyrolysis plant.
We human beings is the maker of the sewage sludge, but at the same time, we also suffer a lot. The sewage sludge is difficult to deal with, and it smells. But with the increasing amount of sewage sludge and population, and the urbanization level has come a new level, the wood charcoal making machine is a growing concern all over the world.
Since the sewage sludge carbonization plant came to the world, it attracted a lot of attention from the scholars and common customers, and they also believe that the carbonizing machine has a promising future in waste treatment, because it can achieve the stabilization and reduction in the treatment process, moreover, the recycling process is harmless to the environment. Although this industry is in the beginning stage, and its development speed is not so fast, but we all believe that with the increasing concern, this technology will develop with amazing speed, and it is wise for all of you to make an investment in this kind of rice husk carbonizer.
