China's waste incinerator in less metal and heavy metal content, but the content of mercury are more in accordance with arrangements of this project, we visited five cities waste incinerators, and they slag were sampled. We also received a slag samples from two other incineration plants. Been incineration system uses marked out in Figure 4. Through these urban waste incineration plant slag test, we draw some conclusions can basically reflect these incinerators burning raw waste metal content. First checks the content of the metal fragments slag. To achieve this, we crushed slag waste disposal equipment, and the size is larger than 2mm sorting out metal fragments. In this way informed, China incineration slag metal content was significantly lower than the average metal content of the slag, Switzerland, China, the proportion was 3.3%, Switzerland 12.6%. If you just consider the words of non-ferrous metal waste, then the difference between the two is even greater in this case, the proportion of Chinese non-ferrous slag waste processor is only 0.24%, compared to 3% in Switzerland Therefore, liquid waste disposal, recycling non-ferrous metal scrap from the slag does not seem to have economically attractive. Slag and fly ash mercury content of this unusual relationship may reflect the incineration temperature is too low. However, the full combustion slag has explained the facts to the contrary. A possible explanation is that, despite the relatively high mercury content in the untreated waste, but this is actually a refuse incineration under "normal" incineration temperature, but the mercury in the flue gas cleaning process The recovery amount is not a lot, so that the accumulation of mercury content in fly ash seem small. Mercury content issues make some questions unresolved. Of course, it is necessary to clarify that the system used to remove mercury in the flue gas constituents really in normal operation, especially activated really blown into the gas stream. At the same time, one must remember is loaded activated carbon is sometimes habitually recycle, which of course will contribute to the success of dioxin clear, but it can also result in the accumulation of mercury in the system and eventually leak into the environment.
