Study On Resource Utilization Of Biomass Ash

With the deepening non-renewable energy crisis, the renewable technology of biomass power generation has been widely applied over China in recent years. If the biomass ash after combustion in the biomass power can’t be used efficiently, it will become a new pollution source, and that will be a great waste. In this study, we’vemade the resource utilization of fertilizer on biomass ash, to avoid the contamination to ecosystem and increase the additional value, the results turned out good ecological benefits as well as economic benefits.1、 The biomass ash had strong basicity with rich mineral nutrition elements, especially in K、P、Ca、Mg、Si, it was a high quality raw material for amendment of acid soil and compound fertilizer production. In the meantime, the amounts of heavy metals were in line with the national standards, so it could be used directly.2、The biomass ash was used as raw matieral to make the biomass fertilizer, with the technology of squeezing granulator, according to the state standard (N6%, P2O53%, K2O18%, SiO28%, MgO1%,CaO10%).3、Application of the biomass ash could promote the pH and decrease the exchange acidityof acid soil effectively, the effect was better than lime and desulfurized fly ash. After application of the biomass ash, the amounts of soil K、P increased significantly, there was a certain quantities of increase in Ca、Mg, but it was non-significant.4、Biomass fertilizer was applied to "Dongkui" and "Biqi" red bayberry, optimized the agronomic characters of the trees, balanced the fruit setting rate, reduced the alternate bearing of the two kinds of red bayberry, and achieved the equilibrium output. Red bayberry with application of biomass fertilizer had better qualities and yields than two kinds of fertilizers used in the experiments for red bayberry. The cost of biomass fertilizer was less than other two fertilizers, so it had a prominent economic benefit.5、The actual yields of the rice increased effectively with the application of biomass fertilizer, it had little effect on the N、P、K amounts of hulled rice. The Si quantities of rice stems and leaves increased on rice with indifference. So a long-term localization expriment is needed to testify the effects.
