Method for regulating nutrients of diammonium phosphate product

一种调节磷酸二铵产品养分的方法

Abstract

The invention discloses a method for regulating nutrients of a diammonium phosphate product, and relates to diammonium phosphate fertilizer. The method comprises the following steps: removing certain water from the sludge filtered through the sewage treatment, calculating the sludge quantity required to be increased according to the slurry spraying quantity and adding the sludge into the returning charge for producing the diammonium phosphate to regulate the nutrients of the product. The water content removed from the sludge accounts for 7 percent of the total weight of the sludge. By using the method, the nitrogen content of the product can be enhanced, the phosphorus content can be reduced, the qualification rate of the product can be ensured, the sludge can be recovered and the environment can be improved and protected. Therefore, the method is suitable for manufacturer of diammonium phosphate.
一种调节磷酸二铵产品养分的方法,涉及磷酸二铵肥料,该方法是用污水处理过滤的淤渣除去一定的水分后,按照产品的喷浆量计算出所需增加淤渣的量,加入到磷酸二铵生产的返料当中,即可调节产品中的养分。淤渣除去的水分量为7%。使用本发明的方法,不仅可以提高产品的氮含量、降低磷含量,保持产品合格,可以同时回收淤渣,改善和保护环境。适用于磷酸二铵的生产厂家。
