Wuhan Qianzishan Waste Treatment Plant said: Traditional Chinese families first put food waste into special garbage bags in the kitchen, put it into the domestic garbage can, and then throw it into the public garbage dump every day, and then transport it from the sanitation center to the waste treatment plant. Buried in landfill. This method is the habit of Chinese families to deal with kitchen waste. In general, this method can also be used for non-recyclable industrial waste and other electronic waste.

The following are the components of the garbage disposal project introduced by Wuhan Qianzishan Garbage Treatment Plant:

1. Enter the garbage sorting system with Dajun in the first stage. Here is the initial elimination phase:

Wuhan Qianzishan Waste Treatment Plant stated: The implementation of classified collection of domestic waste is a very effective way to recycle domestic waste. This is a consensus formed by developed countries in practice. Sorting is a waste treatment method designed to separate materials that can be recycled or are not conducive to the requirements of subsequent treatment and disposal processes. Due to the complexity of municipal solid waste, classification is one of the more important operations in waste resource utilization. It mainly includes: screening, gravity separation, wind separation, magnetic separation, electric separation, flotation, etc.

2、The two stages are the beginning of the culture. Into selected biological treatment systems for perishable organic matter:

Wuhan Qianzishan Waste Treatment Plant said: The biological treatment system mainly includes aerobic composting and anaerobic digestion. Composting is a biochemical process that uses microorganisms that exist widely in nature to transform biodegradable organic matter into stable humus through artificial regulation. Anaerobic digestion is a biochemical sequential reaction process, which uses anaerobic microorganisms growing in sewage, sludge and garbage under anaerobic or anoxic environment to decompose carbohydrates, fats, proteins and other organic substances into stable substances (CH4, CO2, etc.) through hydrolysis, liquefaction and gasification under anaerobic conditions, and at the same time kill bacteria and parasitic eggs, so as to realize the "three" treatment of garbage. The biogas produced by its fermentation can be used for power generation, heating, etc., while the biogas residue and biogas slurry can be used for fertilizer production, which is a better means of resource utilization of urban organic domestic waste. At present, anaerobic fermentation technology is widely used in the comprehensive treatment of most domestic waste in China.

3. In addition, the waste composite material of the inorganic waste composite material system is a new type of material made of two or more solid wastes as raw materials, and a composite material made of all solid wastes as raw materials. Such composite materials include many varieties. According to the different properties of the matrix, it can be divided into three types: polymer-based, silicate-based (ceramic-based) and metal-based. It can replace wood, steel, plastic and porcelain in a wide range of fields. More than 95% of the raw materials used in waste composite materials are new resources (secondary resources) after the regeneration and mixing of various solid wastes. Its cost is much lower than the one-time resources obtained through mining, beneficiation and smelting. They not only solve the problem of environmental pollution caused by solid waste, but also save a variety of valuable disposable resources. They have obvious environmental, social and economic benefits. They are rare materials with environmental harmony.
