The construction waste has many characteristics, such as large quantity, many kinds of components, complex nature and so on. There are many ways to pollute the environment and the form of pollution is complicated. Construction waste can be directly or indirectly pollute the environment, once the construction waste caused by environmental pollution or potential pollution to the reality, therefore, need construction waste crusher to eliminate the pollution, but the elimination of these often require more complex technology and large investment, consumption of high cost of governance, and it is difficult to be polluted the destruction of the environment to fully recover. At present, most of the construction waste in our country is not processed and transported directly to the outskirts of the construction waste disposal pile. With the development of China's economy, city construction scale and improve people's living conditions, construction waste will be produced more and more big, if not timely and effective treatment and utilization of garbage, land occupied by the building will become more serious. Therefore, we need a portable crusher plant to remove the rubbish and to be effectively controlled. Water pollution, construction waste dumps in the rainwater infiltration and leaching, due to heavy metal ions containing waste mortar and concrete blocks in a large number of hydrated calcium silicate and calcium hydroxide and waste a large amount of sulfate ion, gypsum containing waste material containing metal dissolution, and waste paper and waste wood itself from anaerobic degradation lignin and tannin and decomposition of organic acid, organic leachate of waste treatment plant construction yard construction waste is generally strong alkaline and contain a large number of heavy metal ions, hydrogen sulfide and a certain amount, such as uncontrolled let into rivers and lakes or into the ground, will lead to surface and groundwater pollution. Water pollution will directly affect and endanger the survival of aquatic life and the use of water resources.
