Embodiment Construction

[0035] Blank experiment: 10 kg of simulated kitchen waste 2 (C: N=17: 1) composed of potatoes, rice, carrots, leaves, meat, soybeans and inoculated soil is packed into the composting reactor 1, and the air pump 10 provides Under the condition of the ventilation rate of 0.4-0.6L / min, keep the system in the indoor temperature condition, the composting system is in the indoor temperature condition, the operation of the air compressor 10 is automatically controlled by the upper temperature controller 3 and the lower temperature controller 4, and the ventilation volume Adjustment, simulated kitchen waste composting treatment experiment. The original sample was taken at the beginning of composting, and samples were taken every other day after that, and the compost was turned at the same time. The time of taking samples was the same each time. The composting reaction lasted for 26 days and reached a steady state. Determination of NH in samples 4 + -N content and organic matter cont...

Abstract

This invention discloses a method and a device for composting rest materials of kitchens by corrosion-catalyst, which adds a corrosion-catalyst solution into an analog rest material of kitchen composed of potatos, rice, carrots, leaves, meat, soya and plant soil in a certain proportion to process them and keep the compost system under room temperature and ventilation, in which, the application of corrosion-catalyst can increase the degradation rate and degree of organic matters and increases the effect of the compost products, the degradation rate is increased by 76%, the degradation degree of organic matters of the compost products is increased by 16.3% and content of NH4+-N is increased by 62.4%.

Description

technical field [0001] The invention belongs to the technical field of organic waste treatment, and relates to a method and a device for fast composting of kitchen waste using a catalytic rot agent. technical background [0002] With the improvement of the quality of human life, the amount of kitchen waste is also increasing sharply. Due to its high content of water and organic matter, it is different from urban waste, and it is easy to rot and produce stench, which directly harms the living environment and health of human beings. , become a major social hazard, therefore, it is necessary to conduct research on the treatment of kitchen waste. [0003] Kitchen waste is mixed with municipal waste for treatment. Due to the high moisture content and organic content of kitchen waste, it can rot and degrade in a shorter period of time compared to other municipal solid waste. If the kitchen waste is mixed with other municipal waste for incineration, the overall calorific value can...
