Introduction to Factory Waste Treatment Methods in Daily Life: Our daily life inevitably generates some waste, which can be divided into household waste, industrial waste, etc. Industrial waste pollutes the environment more than household waste. Industrial waste refers to the solid waste discharged during the production process in industries such as machinery and light industry. For example, cutting debris, grinding debris, waste molding sand, industrial waste, activated carbon slag in the food industry, solid waste treatment, bricks, tiles, gravel, concrete debris, etc. in the silicate industry and construction industry.
Industrial waste treatment methods
1. Landfill: Landfill waste has low investment and high processing capacity; The technical requirements are not high. However, the long-term occupation of land is enormous and has enormous potential to cause pollution. In the United States and other developed countries, pollution incidents caused by landfill occurred decades later.
2. Composting: Garbage can be turned into organic fertilizer through composting. However, this type of waste fertilizer has low fertilizer efficiency, limited sales, and limited development space.
3. Incineration: The advantages of waste incineration are heat recovery and waste reduction (80% -95% reduction in waste volume after incineration). However, this method is very expensive. Building an incinerator that processes 1000 tons of garbage per day and its related heat recovery equipment will cost approximately 700 to 800 million yuan.
