High temperature aerobic fermentation process: organic waste is produced as organic fertilizer to turn waste into treasure.

 

Ma aiping, a journalist from China science and technology network.

 

Agricultural non-point source and heavy metal pollution has become a major agricultural ecological environment problems of attention in our country, to the modern agriculture and the sustainable development of social economy, the agricultural ecological environment security and the quality and safety of agricultural products pose a serious threat. Due to the particularity of agricultural ecological environment in our country, cannot copy foreign technology and theory to solve China's agricultural sector faces significant environmental and scientific problem, difficult to effectively curb the agricultural environment pollution and increasingly intensified development momentum.

 

On the prevention and control of agricultural non-point source pollution, heavy metal pollution of farmland great strategic needs, the implementation of the national key research and development plan "and for the prevention and control of agricultural non-point source pollution and heavy metal pollution of farmland repair" special emphasis is very necessary and urgent.

 

On March 17, 18, science and technology journal reporter in henan hebi understands, by the ministry of agriculture science and technology development center and the China agricultural university jointly organized the agricultural waste recycling use the scene view to national key research and development plan at the meeting "the agricultural non-point source and comprehensive prevention and control of heavy metal pollution of farmland and restoration technology research and development" focus on special "agricultural waste aerobic fermentation technology and intelligent control equipment research and development" project for two years --

 

Developed is suitable for the large-scale central treatment of animal manure at home and abroad the first set of continuous dynamic slot aerobic fermentation system, realized the composting of scale, industrialization, automation and high temperature fermentation area unmanned operation.

 

Established the international leading the integration of biological, mechanical linkage of solid aerobic fermentation and wastewater biological strengthening treatment technology system, and developed a continuous dynamic slot composting system, integration of silo composting reactor, wastewater tertiary filter and precise irrigation facilities such as autonomous core equipment, realize the linkage control temperature, oxygen and moisture and odor real-time monitoring and intelligent control, the reactor can meet the demand of small and medium-sized farms on the disposal of animal manure.

 

Is established for the first time without broken pure straw heap of aerobic fermentation process, break through the straw manure nutrient solution and the key technology of strain compatibility, of area wide large amount of straw utilization in our country, provides the effective way; For straw moisture content is high, the tomato fruit vegetables high lignification, pesticide residues and bacteria content higher factors, innovation smashing, clear plastic, turns heaps, screening, packing and so on the success of a complete set of facilities vegetables to make organic fertilizer model, pioneered the annual output of 50000 tons of vegetables straw organic fertilizer production line.

 

The utilization of agricultural waste resources will be held on site.

 

"The research of demonstration area construction to the agricultural heartland and typical biome, to explore a way of agricultural waste resource utilization, building economic and efficient ecological circular agriculture development model"

 

From March 17 to 18, the agricultural waste recycling site, jointly organized by the ministry of agriculture's science and technology development center and China agricultural university, will be held in hebi, henan province.

 

Conference, summarized exchanges the agricultural non-point source and comprehensive prevention and control of heavy metal pollution of farmland and restoration technology research and development "focus on special" agricultural waste aerobic fermentation technology and intelligent control equipment research and development "project development progress. The delegates also visited liujiang eco-animal husbandry co., ltd. in henan province to inspect the reactor site, and visited the project r&d technology and equipment application.

 

Li Ji project chief expert, China agricultural university professor told reporters, the journal of science and technology project through high-temperature aerobic fermentation process, the production of organic wastes for organic fertilizer, the waste, in the service of environmental protection and circulation of agricultural industry, for the scientific research unit at the same time provide technology development and enterprise's actual demand docking platform. The compost reactor of the project has the characteristics of short fermentation period, small footprint, high degree of integration of equipment and no secondary pollution. With 90m3 silo reactor as an example, the single equipment can handle 8 to 10 tons of organic waste per day, which can meet the demand of 5, 000 scale farm waste disposal. The development of integrated intelligent reactor composting system has become an effective approach and development trend of China to solve the pollution and prevention of agricultural surface source environment.

 

, deputy director of the ministry of agriculture science and technology development center NieShanMing said at the meeting, the project embodies the science and technology with economy, clear and problem oriented industry guide, with the technology innovation and industry demand correlation degree and the contribution of industrial development, progress is good, bright spot frequency.

 

NieShanMing hope, for the next three years, closely around the green agriculture related scientific researchers to this glorious and arduous historical mission, focus on the goal, collaborative research, the research and development achievements in the fields, field inspection on the production workshop, the research of demonstration area construction to the agricultural heartland and typical biome, to explore a way of agricultural waste resource utilization, building economic and efficient ecological circular agriculture development model, for the rural development of agriculture in new age and new contributions to science and technology innovation causes greater power.

 

The conference released the research report on composting enterprises in China. The project lead unit, China agricultural university, awarded the project demonstration base to 10 enterprises participating in the technology demonstration application.

 

More than 100 leaders and experts from the ministry of science and technology, the ministry of agriculture and the scientific research and teaching institutions attended the meeting.

 

Special progress in the research and development of comprehensive prevention and repair technology for agricultural flour and heavy metal pollution.

 

"To further optimize the development team, explore innovation a batch of prevention and control of agricultural non-point source pollution and heavy metal of new mode and new technology, basic research and the key technology innovation achievements, the project is progressing."
