Problems solved by technology

Some scholars at home and abroad have researched on the reduction of odor emissions during the composting process of kitchen waste, but they mainly focus on the influence of single factors
In the composting process, especially in the composting of kitchen waste, the process parameters such as water content, C / N ratio and ventilation rate are considered at the same time to affect the NH in the composting process. 3 and H 2 The impact of the emission reduction effect of S has rarely been reported

Abstract

The present invention relates to the field of environmental engineering, which discloses a method of reducing odor emissions during the bio-conversion process of kitchen waste, including the following steps: add corn stalk to the kitchen waste, get mixture to adjust the garbageIn the nature of the biological conversion process, the properties include a water content and carbon nitrogen ratio of the mixed material; adjust the amount of ventilation, the mixture is fermented, and the preset time is followed, and the compost is obtained.The method of reducing the odor emissions during the bio-conversion process of the present invention, it is very important to reduce ammonia and hydrogen sulfide emissions during kitchen waste bio-conversion, and alleviate to a certain extent.The problem of the treatment of municipal high wet kitchen waste, and the method is simple, easy to operate, and low in biological conversion raw materials and process conditions, with good environmental benefits and economic benefits, has good promotion value.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a method for reducing odor emission during the bioconversion process of kitchen waste. Background technique [0002] With the rapid economic growth and the acceleration of urbanization, the discharge of domestic waste is increasing day by day, and the environmental pollution is also becoming more and more serious. For a long time, my country's urban domestic waste has been collected, transported and disposed of in a mixed manner. This mode not only has serious resource waste and environmental pollution problems, but also has a poor connection with end-of-life treatment and disposal technologies. Using the method of rough classification of large categories to roughly divide urban and rural domestic waste into kitchen waste, other waste (after material recycling) and dust and collect them separately can avoid the shortcomings of the mixed waste treatment mode and realize th...
