Problems solved by technology

This treatment method not only does not make full use of the microbial populations and small molecule nutrients in the leachate, but the leachate also needs to adopt a complex sewage treatment process to eliminate the microbial populations and small molecule nutrients in the leachate in order to meet the requirements. Environmental emission requirements

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] A method for improving the garbage fermentation effect of a garbage power plant, the method comprising the following steps:

[0025] 1) Establish a garbage pool (such as figure 1 shown)

[0026] The garbage pond includes a garbage pond body 1, a leachate pool 4 arranged at the bottom of the garbage pond body 1, a discharge channel 6 arranged on the side of the garbage pond body 1, and a leachate discharge device 5 arranged at the bottom of the leachate pond 4 , the garbage grab bucket 7 arranged at the top of the garbage pool body 1 and the inclined surface 3 arranged at the bottom of the garbage pool body 1 and used for stacking the garbage pile 2 . The lower end of the inclined surface 3 is close to the leachate pool 4, the leachate pool 4 is lower than the inclined surface 3, and the discharge channel 6 is higher than the ...

Abstract

The invention discloses a method for improving garbage fermentation effect of a garbage power plant. The method comprises the steps that 1), a leachate pool is built in a garbage pool, and leachate generated by a garbage pile is collected; 2), garbage is poured into the leachate pool and is stacked for a period of time; 3), the garbage is fished out and stacked on an inclined surface, and the generated leachate is automatically returned into the leachate pool; 4), new garbage is continuously poured into the leachate pool, the step 2 and the step 3 are repeated; and 5), after the garbage pile is stacked on the inclined surface for a period of time, the fermented garbage is transferred to be used for incinerating power generation. The fresh leachate in the pool contains a large number of microbial populations and nutrient substances, the new garbage is fully in contact and mixed with the leachate, the water content of the new garbage is adjusted, the number of the microbial populations and small molecule nutrient substances in the new garbage are increased, the reproduction of microorganisms is accelerated, so that the fermentation time of the garbage is shortened; and meanwhile, thewater in the garbage is separated out, the fermentation effect is improved, and the heat value of the garbage is improved.

Description

technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for improving the fermentation effect and calorific value of municipal domestic garbage. Background technique [0002] Usually, when municipal solid waste is incinerated to generate electricity, the incinerator has certain requirements on the calorific value of the waste that enters the furnace. The primary municipal solid waste entering the factory in most areas of our country has high moisture content and low calorific value, which cannot meet the requirements of the incinerator. Therefore, it is necessary to properly treat the primary municipal solid waste, so that the waste water can be analyzed and its calorific value can be increased. , so that it can be stably ignited and burned in the incinerator. At present, the commonly used treatment method is to pile up municipal solid waste in the garbage pond and carry out fermentation treatment for 5-7 days. [0003] How...
