How to use cow manure solid liquid separator to ferment cow manure to produce organic fertilizer?  
 
What do we know about how cow dung is fermented?  Many people are not very familiar with it, so LET me briefly say.  The use of cow manure solid liquid separator fermentation cow manure production of organic fertilizer, the cost is small, the quality is relatively stable, market sales, cow manure space is very large.  But the method of traditional pile retting, ferment speed is slow not only, and still cannot let cow dung thoroughly decomposed, easy occurrence after applying farmland "two ferment", cause the phenomenon that burns root to burn seedling.  
How to ferment cow dung is very important.  
 
Cow dung has dried cow dung and fresh cow dung, the following we say their fermentation method:  
1. Dry cow dung: Due to the lack of water in the cow dung can not be fermented, must add enough water, pile into a big pile, and then fermented, covered with sealed plastic cloth, so that the fermentation will be faster.  
2. Fresh cow dung: if it is fresh cow dung, water rinse dung, fermentation also need to use cow dung solid-liquid separator for extrusion dehydration treatment, most of the water is easy to lead to airtight, microorganisms can not produce fermentation.

1. Prepare and add bacteria: Prepare cow dung to be fermented.  
2. Cow dung pile construction: the prepared cow dung should be built while the bacteria are scattered. The pile height and volume should not be too short or too small.  
3. Adjust water: The water content of fermented cow manure should be controlled in 40%-65%.  Water judgment: grasp a handful of cow dung, fingers see water but not dripping, the landing is appropriate.  Water ferment is slow, water aeration is poor, still can cause "corrupt bacterium" work and produce stink, therefore, must grasp good moisture content.  
4. Startup temperature.  The starting temperature should be better than 15 degrees Celsius (four seasons can work, not affected by the season, in winter as far as possible in indoor or greenhouse fermentation), fermentation temperature control in 70-75 degrees Celsius is appropriate.  
5. Mix well and ventilate.  Cow dung fermentation needs good (consumption) oxygen fermentation, therefore, in the process of operation, oxygen supply measures should be increased, so as to mix evenly, frequently turn, ventilation is appropriate.  Otherwise it will lead to anaerobic fermentation and odor, affecting the effect of fertilizer.  
6. Fermentation is complete.  Generally, after 48 hours of cow dung accumulation, the temperature rises to 50-60 degrees Celsius, the third day can reach more than 65 degrees Celsius, in this high temperature to overturn once.  Under normal circumstances, there will be two times of high temperature above 65 degrees Celsius in the fermentation process, and the fermentation can be completed by turning over two times. Normally, the fermentation can be completed within a week.  The material was black and brown, and the temperature began to drop to normal temperature, indicating the completion of fermentation.  
 
Matters needing attention:  
 1. Cow dung must be fermented and decomposed before it can be used on crops. Otherwise, some pathogenic microorganisms in cow dung will burn the root system of crops.  Drying and air drying can be, but after drying, the nutrition of cow dung will lose part of, cow dung through the dryer drying, can achieve the purpose of drying, can also achieve the purpose of deodorization.  Can also reduce artificial labor intensity and so on.  
 2. The moisture after drying is controlled at about 25% in winter and 15% in summer, in order to prevent the follow-up process can not be completed, some dryers can not control the moisture content of drying cow manure, resulting in the continued fermentation of cow manure particles after placing organic fertilizer.  
 3 summer, autumn season morning and evening to uncover the film ventilation once (1 ~ 2 hours), when the weather is clear, the film can be uncovered in the evening in the first day, the next morning cover.  After 4 ~ 6 days of composting, the temperature can rise to 60 ~ 70℃.  Pile 10 days can turn pile, pile retting 20 days that can be ripe, fertilizer points improve, the elimination of pests.  
 4. For the selection of fermentation bacteria, we must select those with high bacterial activity, preferably those with primary bacteria.  This fermentation is stable and not easy to fail.
