According to records, the Spring and Autumn period, the Warring States period, the Qin and Han dynasties had already used livestock manure and agricultural waste as fertilizer. Northern Wei Dynasty 630-640, Jia Sixie "Qi people to the art" recorded, "where people harvest the field after the autumn, all grass, grain, etc., and must be collected in a place, a daily cloth cattle foot, three inches thick, every Pingdan collected and piled up, but also according to the front cloth, after the night is piled up, a cow in winter, stepping into 30 cars." This is a composting method combining gasket and compost. At that time, it was called the manure method, and this is the earliest composting method in China.
In 1149 AD, "Chen Fu Nong Book" good root and seedling chapter describes the process and characteristics of aerobic composting, which is the earliest scientific record of composting in China: "In the beginning of spring and then turn to plow, with manure, if you use Ma Gu you good." But hemp is difficult to make, must be fine pestle broken, and firearm castrator, such as composition; When its fever, raw rat hair, that is, spread the middle of the heat in the four sides, convergence of the four sides of the cold in the middle, and pile the cattice; Do this three or four times, until it does not heat up, but it can be used, or else it will burn and kill everything."
New quality productivity of composting technology
Although domestic compost fermentation technology has made progress in some aspects after more than 20 years of development, such as shortening the production cycle and improving the level of mechanization, the problems of stench and high cost in the process are still difficult to overcome.
At present, China's organic fertilizer industry is in urgent need of new and efficient organic fertilizer fermentation technology in line with national environmental protection policies and market demand, which requires low investment cost, odor-free fermentation process production, environmental friendliness, and high economic benefits, so as to promote China's organic fertilizer industry to achieve a true sense of "new quality productivity".
NCS intelligent molecular membrane fermentation technology
NCS intelligent molecular membrane fermentation technology is an advanced organic fertilizer fermentation technology. A special functional membrane is used as a covering for aerobic fermentation treatment of organic waste using high temperature aerobic fermentation process.
In the process of fermentation, a special molecular film is covered on the surface of the pile to form a closed environment, reduce pollution gas emissions, and oxygen is supplied at the bottom of the pile through aeration pipes to promote rapid decomposition of the material, which can be static fermentation in the open air, and the process takes 15-25 days to produce organic fertilizer.
The technology has the advantages of low investment, simple operation, no odor pollution and wide application. Can be used in chicken manure, cow manure, pig manure, sheep manure and other livestock manure, straw, tail vegetables, sludge and other agricultural production of most of the waste, produce high-quality organic fertilizer.
In order to make the whole link of organic fertilizer from fermentation to application in farmland efficient and convenient, Zhonghai Environment has built the whole industrial chain equipment, from front-end pretreatment equipment, raw and auxiliary materials mixing equipment, fermentation equipment, fermentation auxiliary equipment, back-end organic fertilizer deep processing equipment, fertilizer equipment involving waste generation and collection to field utilization. It provides an environmentally friendly, easy to operate and low-cost way of agricultural waste utilization for aquaculture and planting industry, and realizes the green development of agriculture.
Project case
NCS intelligent molecular membrane fermentation technology by integrating intelligent, automated and efficient means, completely changed the traditional way of compost fermentation, greatly improving the production efficiency and product quality. And with its unique advantages and innovation, it has become the "new quality productivity" of compost fermentation technology in the future, injecting new vitality and motivation into the development of compost treatment industry.
