1. Technical Sources of Tank Fermentation Equipment
There is a long history of composting at home and abroad, and the composting systems used are also various. In the early stage, the composting system is usually simply composting the raw materials into a pile for a long time, with little ventilation and management. This composting system has been widely used in rural areas for a long time, and is suitable for small-scale organic fertilizer production of farmers. Because it can not meet the requirement of continuous oxygen supply, anaerobic microorganisms occupy a dominant position in the composting process.
Its essence is an anaerobic composting, which has the characteristics of slow heating, low temperature, slow decomposition of organic matter, easy to produce hydrogen sulfide and other odorous compounds. In order to overcome the shortcomings of this traditional composting system, various modern composting systems have been developed abroad since 1950s. These systems have many characteristics, such as high degree of mechanization, large capacity, fast composting speed, high degree of harmlessness and friendly environment, so they have been widely used.
A large number of reactor composting systems have been developed around the world, some of which are called "container systems" or "digesters" or "fermenters". The equipment of composting reactor must have the function of improving and promoting microbial metabolism. In the process of fermentation, facilities such as turning over, aeration, agitation, mixing and assisting ventilation should be operated to control the temperature and moisture content of the compost.
At the same time, the problem of material movement and discharging should be solved in the composting of reactor, so as to increase the fermentation rate, shorten the fermentation period and realize the machine. The purpose of mechanized production.

Product Scheme and Market AnalysisThe product is garden greening matrix, which meets the requirements of "Mud for Landscape Greening in Sewage Treatment Plant Sludge Disposal" (GB/T 23486-2009). The total nutrients are more than 3%, the organic matter content is more than 25%, and the water content is less than 30%. At present, sludge treatment products have been widely used in landscaping, forestry and other aspects. It not only solves the problem of sludge disposal, but also realizes the environmental benefits of water pollution control and social benefits.The application of sludge products mainly includes the following aspects:1) For landscape greening. At present, there is no specific standard for the application of sludge-treated products in gardens and flowers in China, usually referring to "Mud for Landscape Greening in Sewage Treatment Plant Sludge Disposal" (GB/T 23486-2009). The "nutrient base" of flowers and plants in municipal gardens is usually made by mixing sludge products and soil in a ratio of 1:1. The application of this "nutrient base" or "nutrient bowl" can greatly speed up the process of seedling cultivation and make the seedlings grow more vigorously. 2) For lawn cultivation. At present, there is no specific standard for the application of sludge-treated products in lawn cultivation in China. Usually, the standard of "Mud for Landscape Greening in Municipal Sewage Treatment Plant Sludge Disposal" (GB/T 23486-2009) is consulted. The sludge-treated products are suitable for green space use without worrying about heavy metals entering the food chain. The sludge treated products, whether applied alone or combined with chemical fertilizers, have obvious effects on garden green space (including lawn, highway slope protection and greening plants in residential areas).
Soil physical and chemical properties were improved to varying degrees, and plant growth responded well. The actual production showed that the sludge treated product combined with chemical fertilizer had better effect, could shorten the emergence and turf formation time of turf grass, and significantly improve the growth of turf grass at the initial stage of planting. Therefore, in order to meet the needs of soil and water conservation and rapid landscape restoration, appropriate amount of nitrogen fertilizer can be added in combination with sludge-treated products to accelerate plant growth and shorten the time of planting or turf-forming.
For garden plants in the growing period, only sludge treatment can be applied to maintain the basic needs of plant growth and reduce the input of personnel such as pruning and maintenance. No need to add chemical fertilizer. In addition, the production of turf with sludge treated product matrix can not only provide sufficient nutrients and support strength for turf growth, but also reduce the weight of Turf by 36% per unit area. 3) Used for Expressway greening. At present, there is no specific standard for the application of sludge-treated products in expressway greening belts in China. Usually, it refers to the standard of "Mud for Landscape Greening in Municipal Sewage Treatment Plant Sludge Disposal" (GB/T 23486-2009). The greenbelt of expressway has the function of beautifying the environment of expressway, preventing soil erosion and protecting subgrade.
The anti-glare function of trees in the separating zone is particularly important. The soil of newly built greenbelt of highway is mostly raw soil and mixed with construction waste. Its soil contains less plant nutrients, serious lack of organic matter, poor physical, chemical and biological properties, and it is difficult for plants to grow well.
In the past, the effect of applying chemical fertilizer was poor because it could not improve the soil. Adding appropriate amount of nitrogen and phosphorus fertilizer into the sludge treated products will become a compound sludge product with the characteristics of "high organic matter, complete nutrients, reasonable mix, soil improvement and fertilizer field".
It has a good effect to apply it to the green belt of expressway. Moreover, the greenbelt of expressway is a relatively closed area, after using sludge products, heavy metals and other pollutants will not enter the food chain. Therefore, the application is safe.About Our Company:Qingdao Youfeng Environmental Protection Equipment Co.,Ltd. is a professional manufacturer of the environmental protection equipment.
