City Sludge can Actually Make Organic Fertilizer

The disposal of a large amount of activated sludge in the process of municipal wastewater treatment has been a difficult environmental problem to solve. The organic matter content of sludge, nitrogen, phosphorus and potassium nutrients are often at the same level as livestock manure, and sometimes the organic matter of sludge is higher than livestock manure, so it is a very good nutrient resource.

The sludge organic fertilizer production line developed and produced by Sande Machinery mainly treats domestic sewage, the organic content of sludge is high, rich in nitrogen, phosphorus, potassium, active bacteria, etc., and the content of heavy metals and other elements is low.The sludge fermentation and stabilization, sterilization and harmless treatment can be used as an organic fertilizer, not only to avoid the secondary pollution of sludge, but also to use the active ingredients in the sludge, turning harm into profit, turning waste into treasure. It can be used as an organic fertilizer to avoid secondary pollution of sludge, and at the same time use the active ingredients in sludge to turn harm into benefit and waste into treasure.
