On the development of waste disposal
Thread Content
When it comes to environmental protection, people generally think of pollution caused by companies such as chemical industries, such as the emission of carbon dioxide and the emission of toxic and harmful gases. But when my classmates were engaged in garbage disposal, they realized that garbage disposal is also a big issue in environmental protection. According to personal understanding, domestic waste disposal seems to rely on foreign technology, and there is also the invasion of some foreign waste. Let's all share our views on this.
The so-called first of the three modernizations, resource utilization is the best. Such as waste-to-energy generation, waste entering cement for solidification, etc.
I think waste-to-energy generation is not worth promoting economically because the money spent to implement this process is far greater than the value of generating electricity. Therefore, if there are other processes, do not choose this method. This post was last edited by lyhh9024 on 2009-3-3 17:24 ]
We have visited the landfill in Shijiazhuang, and we don’t know how the bottom of it is treated, and whether there will be leakage of garbage liquid. It is very worrying. The generated methane cannot be effectively treated, which is also very dangerous. Plastic bags are flying all over the mountain, and the partition net cannot completely solve the problem. The most common methods of garbage disposal in China seem to be incineration and landfilling.
Garbage belongs to the category of solid waste. Solid waste can be divided into industrial, agricultural solid waste and domestic waste according to its source. According to characteristics, it can be divided into hazardous waste and general waste. The management of hazardous waste must be handled by units with relevant corresponding qualifications. Domestic waste, foreigners say that the classification of domestic waste in my country is the least clear, but I think it is the clearest. * * . Because too many Chinese waste pickers have helped. I have never seen landfills in other places, but our domestic waste landfills here are completely unacceptable. No one dares to get close.
The current method of garbage disposal is mainly landfill, which is equivalent to leaving the current troubles to future generations. Sooner or later, the pustules will burst. Therefore, from the source of garbage generation to post-processing* * We need to participate seriously and actively. For example, even if the cost of waste-to-energy generation is uneconomical, we must be financially supported. We don’t know where the waste disposal fees collected have gone! :'(
E-waste is really dangerous. I saw someone selling e-waste in a digital mall and thought I was doing something great. Tell him about the dangers of e-waste and he doesn’t understand at all. It’s so sad.
Domestic waste treatment has just emerged, and process equipment basically relies on imports! ! !
Recently, it seems that the unit has taken on another garbage disposal project. It is a bit too perfunctory. It cannot be justified from the actual economic and environmental aspects. It is also a typical example of "theory" being higher than reality.
Currently, waste is incinerated and landfilled, which directly pollutes the atmosphere and leaves harm to future generations, neither of which is a long-term solution. But look at how foreign countries often put their garbage in the third place * * Luck, I guess they don't have a good idea. If you imagine that there is garbage in space, it can only be said that human beings are in a cocoon.
