Technology for microbial wall breaking and solid-liquid separation of fruit and vegetable wastes

Abstract

The invention discloses a technology for microbial wall breaking and solid-liquid separation of fruit and vegetable wastes. The technology comprises the following steps that 1, the fruit and vegetablewastes are broken; 2, a microbial preparation is prepared; 3, the microbial preparation is used; and 4, liquid is discharged from a biochemical fermentation tank, and residual solid matter is pressedand dehydrated by adopting a screw press. According to the technology, the fruit and vegetable wastes are treated by the technology of microbial wall breaking and solid-liquid separation, aiming at the high water content of the fruit and vegetable wastes and the limitation that plant cell walls cannot be broken by conventional methods, bound water in plant cells is released, and the effective dehydration of the fruit and vegetable wastes is achieved by microbial enzymolysis; the microbial technology is used, the limitation of the plant cell walls is quickly broken by using the enzyme producedby microorganism, the effective solid-liquid separation is achieved in the processing link of the fruit and vegetable wastes, the reduction of the fruit and vegetable wastes is achieved to the greatest extent in a short time, and a foundation is laid for the effective disposal of the next step.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment, and in particular relates to a process for microbial wall breaking and solid-liquid separation of fruit and vegetable waste. Background technique [0002] As people's lives become richer and people pay more and more attention to healthy diet, the supply and consumption of vegetables and fruits are increasing year by year. The sorting and stripping of vegetables and fruits in the production link, circulation and transportation link forms a large amount of fruit and vegetable waste. The output of fruit and vegetable waste in our country is huge, and the random stacking and disposal of garbage is easy to breed corruption and produce various pathogenic bacteria, which affects the appearance of the city and endangers people's health. The seepage water generated during the stacking of fruit and vegetable waste with high moisture content can dissolve harmful substances such as heavy met...

Problems solved by technology

Moreover, random stacking of fruit and vegetable waste can easily lead to an anaerobic environment in the interior. The acidification speed of fruit and vegetable waste is relatively fast, and its metabolism produces organic acids, sulfurized oxygen, etc., which emit foul odors, which will also affect the health and living comfort of residents.

[0003] At present, there are few new processing technologies for domestic fruit and vegetable waste, and most of the fruit and vegetable waste is dumped randomly, causing serious environmental problems; a small part of fruit and vegetable waste is used for composting to realize resource utilization

However, the high moisture content of fruit and vegetable waste severely limits the development of resource utilization of fruit and vegetable waste.
