According to the “First National Pollution Source Survey Communique†issued in 2010, the actual sewage treatment capacity of China's sewage treatment plants is 210.31 billion tons. According to Professor Liu Yangsheng, professor of the Beijing University’s School of Environmental Science and Engineering and executive deputy director of the Beijing Municipal Solid Waste Key Laboratory, at present, China produces about 9 million tons of dry sludge annually, which accounts for about 0.3% of the total amount of waste, and accounts for more than 10% each year. The speed is increasing. How to deal with so much sludge?
The commonly used methods for sludge treatment include: drying, incineration, landfill, composting, and investment in the sea. Among these treatments, composting is the most cost-effective and efficient way to use it. However, in order to harmlessly dispose of the sludge, it is not only a matter of simple accumulation and fermentation. Once it is handled badly, it will cause serious secondary pollution. Therefore, when composting, it is necessary to add a professional fertilizer starter. Practice has proved that fermenting the sludge with organic fertilizer using a golden bait fertilizer starter has fast fermentation, good fermentation, high-temperature fermentation, low-temperature fermentation, and greatly reduced production time. The process of "deodorization", "decay", "killing insects", "sterilization" and nutrient conversion of sludge is completed by the powerful "biochemical reaction" formed by the functional microorganisms during rapid and massive reproduction. To achieve "harmless" and "resources."
The harmless treatment technology for fermenting the sludge into organic fertilizer by using the Kinpo Fertilizer Fermenting Agent (for details, please click) is for the general users to refer to:
Sludge; Goldfish fertilizer starter; cow dung or straw powder, mushroom residue, peanut shell powder, rice husk, sawdust, etc.; rice bran or bran.
2, material ratio.1 kg of Kinpo Fertilizer Fermenting Agent can ferment about 4 tons of sludge, and need to add about 30-50% of cow manure or straw powder, mushroom residue, peanut shell powder, rice husk, sawdust and other organic materials in order to adjust the ventilation Sex. Where rice husks and sawdust are added, the fermentation time should be prolonged because of its high cellulosic lignin. Add 5 to 10 kg of rice bran (or substitutes such as bran and corn flour) per kilogram of Fertilizer Fermentation Fermenter, mix and dilute evenly, and spread it evenly into the material pile. The use effect will be better.
3, adjust the moisture.The moisture content of the mixed fermented material is adjusted to 60 to 65%. Judgment method: grab a handful of material, finger-pointing see the watermark but not dripping water, landing is scattered suitable.
4, materials build a heap.The materials that are mixed well and adjusted to be well-watered are to be built. The stack height and volume should not be too short or too small. Requirements: The stack height is 1.5 to 2 meters, the width is 2 meters, and the length is 2 to 4 meters or more.
5, temperature requirements.The starting temperature should be better than 15 °C (four seasons can be operated, not affected by the season, winter as much as possible in the indoor or greenhouse fermentation), fermentation temperature control at 70-75 °C is appropriate.
6, mix ventilation.The golden treasure organic fermentation starter is in need of good (consumption) oxygen fermentation, it should increase the oxygen supply measures, so that turn to, mix well, ventilation is appropriate. Otherwise it will lead to anaerobic fermentation and produce odor, affecting the fermentation effect.
7, the completion of fermentation.On the 2nd to 3rd days, the temperature can reach 65°C or more, and it can be turned over at this high temperature, and it can be turned over 2~3 times. The fermentation can be completed within about one week (the temperature starts to drop to room temperature). If sawdust, sawdust, and rice husks are excessive, the fermentation time should be extended until it is fully decomposed.
With this simple and easy aerobic fermentation technology, organic fertilizers that are fermented from sludge with a goldfish fertilizer fermentation agent will not only render the sludge harmless, but also play a role in waste recycling. The organic fertilizer fermented by the sludge not only has good fertilizer effect, but also is safe and convenient to use, and can also fertilize the soil and improve the utilization rate of chemical fertilizers. It is worthy of widespread application by users. For details, please contact: Beijing Huaxia Kangyuan Technology Co., Ltd. Telephone Toll Free Hotline
