What Is Anaerobic Fermentation of Domestic Waste?
Anaerobic fermentation is one of the effective ways to realize recycling of domestic waste. Anaerobic fermentation of domestic waste refers to the decomposition of organic matter by microorganisms under anaerobic conditions, in which C, H, O are converted into biogas - methane and carbon dioxide, while trace elements such as N, P, K are stored in the residue and be converted into matters easily absorbed and utilized by passive plants.
Wet Continuous Anaerobic Digestion and Recycling Process
The wet continuous anaerobic digestion process is a mature domestic waste treatment technology. The recycling process mainly includes four stages: waste sorting and pretreatment, anaerobic digestion, power generation with biogas, and residue recycling, to realize the maximum degree of resources.
Domestic Waste Sorting and Pretreatment
After the mixed garbage is weighed and measured, it enters the sorting system. After the bag is broken, it is evenly sent to the trommel screen by the feeder for screening, and the small particle garbage with suitable particle size is screened and then sent to the anaerobic fermentation process. The waste materials with size above 80mm continue to be sorted and recycled before being crushed, and then the crushed waste is sent to the anaerobic fermentation room.
Mechanical sorting is mainly composed of two parts: magnetic separation and mechanical crushing. After this process, the ferrous metals in the garbage are sorted and recovered, and the material on the screen is crushed and processed to reduce the particle size, which is conducive to improving the subsequent sorting effect of hydraulic separation process.
The material under the sieve is first subjected to magnetic separator to separate ferrous metals, and then passes through the deep water rolling separation washing equipment. Depending on the specific gravity of the substance, heavier substances such as muck, batteries, and stones sink into the lower part of the device, while lighter substances such as paper and plastic float on the upper part. The sinking objects and floating objects are respectively sent to the recycling system for recycling and disposal. Finally, material in the middle level is sent to the precipitation treatment tank, and the precipitated material is sent to the anaerobic fermentation process.
Anaerobic fermentation is an important way to recycle municipal solid waste. In order to cooperate with the smooth progress of anaerobic fermentation of domestic waste, Zhengzhou Yuxi Machinery has designed and produced domestic waste crushing and sorting line for pretreatment of MSW. The MSW separating production line is mainly composed of conveying equipment, sorting equipment and crushing equipment, which can well fit the domestic waste sorting and preprocessing process in the anaerobic fermentation process.
