Now the environmental governance requirements are very strict, whether it is domestic sewage, sludge or industrial sewage, sludge, are in urgent need of treatment, the sludge into organic fertilizer, so that the sludge has also been treated.  
 
The sludge fermentation into organic fertilizer, not only can reduce urban pollution to achieve waste recycling, applied to farmland can also fertilize the soil, improve the quality of agricultural products, etc., can be said to kill multiple birds with one stone.  Using microbial fertilizer starter to ferment sludge into organic fertilizer is a good choice.  Microbial fertilizer starter cultures are natural compound bacterium fermentation agent, at the same time to absorb the international high-end microbial engineering technology and the essence of the process flow, process seiko developed by high-tech filtering purification and rejuvenation, etc, is made up of bacteria, filamentous fungi, yeast and actinomyces and so on the many kinds of beneficial natural microbial components of compound bacterium group, has a very strong ability of aerobic fermentation, decomposition,  Fermentation function is strong, is in line with the national environmental protection and green food survival requirements of the special microbial fermentation agent.  
 

The operation method is as follows:  
1. Activation process of Environment-friendly probiotics:  
With 4 kg of 70 degrees Celsius hot water completely dissolved 1 kg as gold original bacterium nutrients, with 4 kg of cold water to make the solution temperature down to 30 degrees Celsius, add 1 kg of the original bacteria, blending, sealed (25 to 35 degrees Celsius), anaerobic fermentation - 48 hours for 24 hours, summer winter fermentation used after 72 hours, measure the PH value of 4.0 the following,  By sweet and sour taste, then make a successful group (10 kg).  Namely nutrient: original bacteria: water = 1:1:8.  
2. Strain dosage.  1 kg microbial starter can ferment about 5 tons of sludge (water content is 65%).  According to the weight ratio of about 20-30% straw powder, mushroom residue, peanut shell powder, or rice husk, sawdust and other organic materials in order to adjust the ventilation.  If rice husk and sawdust are added, the fermentation time should be prolonged because of their high cellulose and lignin.  Strain dilution: add 5-10 kg rice bran (or wheat bran, corn flour and other substitutes) per kg of fermentation agent, mix and dilute evenly, and then sprinkle evenly into the material pile, the use effect will be better.  
 
3. Mix well and ventilate.  The fermentation agent is a good (consumption) of oxygen microorganisms, so it is appropriate to increase the oxygen supply measures, so as to mix evenly, turn frequently and ventilate.  Otherwise it will lead to anaerobic fermentation and produce odor, affecting the effect.  
 
4. Moisture judgment.  The moisture content of sludge added with organic materials should be controlled at 60 ~ 65%.  Water judgment: hold a handful of material, see watermark but do not drip, fall to the ground is appropriate.  Less water fermentation is slow, more water ventilation is poor, but also lead to "rotten bacteria" work and smell.  
 
5. Adjust the temperature.  The starting temperature is better at 15℃-20℃, after 48 hours, the temperature can rise to 50-60℃, the third day can reach 75℃ or above, in this high temperature to be overturned several times, the temperature is stable at 55-65℃.  
 
6. Fermentation is complete.  Generally within a week, the material can be deodorized and fermented.  The temperature begins to drop to room temperature, indicating that fermentation is complete.  Such as sawdust, wood chips, rice husk auxiliary materials too much, should prolong the fermentation time, to be fully mature.
