| titleOfInvention | Application of biodiesel waste liquid in preparation of liquid fertilizer |
| abstract | The invention belongs to the technical field of wastewater treatment, and particularly relates to application of biodiesel waste liquid in preparation of liquid fertilizer. According to the application provided by the invention, the biodiesel waste liquid can be directly used in the preparation of the liquid fertilizer through simple steps of filtering, demulsifying, neutralizing and the like, the method is simple, secondary waste liquid can not be generated, and the added value of the product is improved. The biodiesel waste liquid is mixed with nutrient elements such as nitrogen, phosphorus, potassium, calcium, magnesium, boron and the like in a specific ratio to be used as a plant floating seedling culture nutrient solution, so that the growth of seedlings is facilitated, and the growth vigor of the plant floating seedling culture nutrient solution is superior to that of a floating seedling culture special nutrient solution. |
