城市固体废物(每天的垃圾/家庭的r

Presently there are three ways of garbage treatment: landfill, composting and incineration for generating electricity. Many garbage landfill sites were set up around the cities. This could be a great step forward in comparison comparing with the traditional way of random disposal. But this is still far behind the requirement of innoxious treatment and could easily cause secondary pollution. Composting is neither the ideal way of treatment. Experiments show that the contents of heavy metals in the vegetables grown with garbage compost are far more than the allowed standard and very harmful to human health. In comparison with the above two ways of garbage disposal, incineration is the best way to dispose garbage. After incinerated, the heat can be used to generate electricity and/or supply steam for civil use. Besides, the ash and slag can be used as cement additive and construction materials. The goal of recycle and reuse can reach. After incinerated, garbage is reduced weight by 75% and volume by 90%. The goal of decremental treatment can reach. After incinerated by high temperature in incinerator, pathogens in garbage are killed thoroughly. The goal of biosafety disposal can reach.In sum, daily garbage incinerator and generator system is the useful and efficient measure of environment protection to realize Recycle, Reuse and Reduce of garbage disposal.
