Problems solved by technology

However, problems such as resource recovery rate and low product value in existing technologies, environmental odor, and poor front-end classification efficiency have become urgent problems to be solved in the perishable waste treatment industry.
The traditional perishable waste treatment process has obvious disadvantages, such as sanitary landfill to treat polluted soil and groundwater, and incineration treatment due to the high content of moisture and organic matter in perishable waste, which easily produces air pollution such as dioxin while increasing the treatment cost; high-temperature composting The power consumption of the treatment is huge, and the product contains too much salt and oil, making it difficult to recycle; the biogas power generation treatment project has a large investment and is difficult to operate stably

Abstract

The present invention relates to the technical field of perishable waste treatment, in particular to a perishable waste treatment process with low energy consumption and high weight reduction rate, including: 1) picking out non-degradable substances from perishable waste, crushing them to pass through a 20-mesh sieve, and placing 2) Add 1.0 to 2.5kg of compound microbial bacterial agent per ton of perishable garbage every 12 hours, and aerobically degrade it at room temperature for 48 to 72 hours. The compound microbial bacterial agent is specifically polyvinyl alcohol, sodium alginate, acid Modified Populus euphratica powder is cross-linked with aminated biochar and prepared by adsorbing microorganisms as a composite carrier. A reduction rate of not less than 90% of perishable waste can be achieved in a relatively short period of time, and organic macromolecules can be degraded into small molecular substances, realizing the transformation of perishable waste with low energy consumption, and the degradation process is well controlled Odor generation.

Description

technical field [0001] The invention relates to the technical field of perishable garbage treatment, in particular to a perishable garbage treatment process with low energy consumption and high weight reduction rate. Background technique [0002] Perishable garbage in the traditional sense refers to food waste, specifically refers to food waste produced in the production and life processes of catering operators, unit canteens, family life, etc., leftovers, vegetable stems and leaves, meat offal, fruit shells, etc. Melon skin and so on are all perishable garbage. The composition and production amount of perishable garbage are affected by many factors, but generally have the following characteristics: 1) high moisture content, the moisture content of perishable garbage is generally higher than 60%, even up to 80%, which is relatively high. High moisture content not only brings greater difficulty and cost to collection, transportation and treatment, but also easily contaminate...
