Sludge is formed during the rain or sewage treatment process. It seems to have no effect on our side, but it also contains a large amount of organic matter and abundant nutrients such as nitrogen and phosphorus. However, if properly treated, it can become polluted. Generally, landfill, fertilizer production, power generation, heating and other treatment methods are used. Landfilling involves the in-depth landfill of some inseparable and unusable materials, allowing the natural world to decompose through long-term physical and chemical treatments; It is to use the organic matter in the sludge to make agricultural fertilizers. It uses the pyrolysis and fermentation of sludge during power generation and heating, and generates heat and biogas during fermentation. Among these treatments, fertilizer production is the most cost-effective and economical way to use it effectively.
The method of composting with sludge is simple. Add appropriate amount of crushed straw, sawdust and other organic materials in the sludge, and then put a small amount of jinbao fertilizer starter into the sludge and mix well. Generally 7-10 days can be completed by fermentation and can be used or sold at ease. Details can visit the website or consult.
