Landfilling garbage is a safe and effective method right?

Wrong! I am currently researching the disposal of municipal domestic waste. The traditional methods of municipal waste disposal are: sanitary landfill, composting, and incineration. According to strict environmental impact assessment requirements, these methods are now difficult to meet the modern urban waste treatment, sanitary landfill, composting, will produce a large amount of garbage leachate, garbage leachate is a kind of complex composition, extremely difficult to deal with the high concentration of organic wastewater, the cost of treatment is very high. Therefore, it is necessary to find an efficient, feasible, low-cost treatment technology to solve the "garbage crisis" in the process of urbanization.

Like you said, landfills have many disadvantages, such as occupying a large amount of land, generating leachate that causes serious pollution of groundwater, and generating gases such as methane and hydrogen sulfide (which can't be efficiently collected and treated, and pollute the air). Therefore, in an environmental sense, landfilling is a negative emergency measure and is not a permanent solution for the growing amount of waste. After the national standardization of landfill regulations, the requirements and inputs for site infrastructure, long-term treatment of leachate are even higher, and operating costs have increased substantially, so that low-cost operation of traditional landfill methods will no longer be feasible. If you are interested in the technology of waste disposal, we are looking forward to discussing and learning with you***~~QQ534068909
