First, the newly mobilized or concentrated domestic garbage shall be pretreated. The method is to spray microbial agents on the surface to quickly eliminate the odor (especially the odor), prevent the odor from affecting the surrounding environment, prevent the breeding of mosquitoes and flies, effectively improve the internal environment of the treatment plant, and provide a good working environment for the next treatment process.

Then, the pretreated garbage is sent to the fully enclosed sorting workshop and enters the unmanned automatic garbage sorting system. The sorting workshop is equipped with dust removal equipment, air purification equipment and monitoring equipment.

After automatic sorting, the garbage is sorted into the following five categories: organic materials: about 70% of the total garbage (5-10% of which are difficult to identify non organic materials); Inorganic materials: accounting for about 15% of the total, such as sand, sand, etc; Non recyclable combustible materials: about 2-5% of the total, such as old clothes, wood and bamboo, and straw; Films and plastics: about 8-10% of the total; Metals: about 3-5% of the total.

The classified domestic garbage shall be treated separately:

Organic materials: materials with large proportion and difficult to handle. We use microbial fermentation technology to simplify complex problems. If urban domestic sludge can be added for treatment together, the treatment effect will be better. After treatment, these organic materials are loose, breathable, odorless and odorless. Various harmful substances, including harmful heavy metal elements, are effectively degraded. All indicators meet the requirements of "bio organic fertilizer" ny884-2012;

Inorganic materials and non recyclable combustible materials: the "biomass composite crystalline steel" building material technology owned by our company can be used to produce new environmental protection building materials.

Thin film plastics and metals: it is well known that such wastes can be recycled and will not be repeated here.

Using microbial technology to treat urban domestic garbage, so that these garbage can be comprehensively utilized or smoothly returned to nature, is a relatively complete garbage treatment and disposal technology at present, and is a technology worthy of selection.
