项目摘要

It assimilated carbon dioxide into the MSWI bottom ash (carbonation), and the durability in a long-term effect of the pure water quality and processing of making to the carbonic acid was examined by the upward style column pass examination. The substantial change was not admitted and was steady though filled abolition standard (pH5.8-8.6) from an initial stage, switched to the nitric acid of pH4, and passed the ooze water pH of the processing of making to the carbonic acid incineration ash. Moreover, a simple LCA evaluation when processing of making to the carbonic acid was executed to the incineration ash as a preprocessing of reclamation it was executed. In the processing of making to the carbonic acid ash, it was presumed to be able respectively to reduce LCC and LCCO2 by about 60 percent compared with the normal ash.

它将二氧化碳吸收到垃圾焚烧底灰(碳化)中，并通过上行柱通过试验检验了纯水水质和制取碳酸过程的长期效果的耐久性。通过对碳酸焚烧灰制取过程中的渗水pH从初始阶段的填充废止标准(pH5.8-8.6)，改为pH4的硝酸，并通过了制取过程中渗出水的pH值，不允许有实质性的变化，并保持稳定。此外，在对焚烧灰进行制造碳酸的处理时进行简单的LCA评估，作为对其进行回收的前处理。在碳酸灰制取过程中，与普通灰制取相比，可分别降低LCC和LCCO2约60%。
