| titleOfInvention | Preparation method of activated sludge spray-type fertilizer |
| abstract | The invention discloses a preparation method of activated sludge spray-type fertilizer. The preparation method comprises the following steps: mixing the activated sludge with water, and sieving with a 20-mesh sieve to obtain a suspension; adding ferric sulfate, stirring at a speed of 150-200r/min, performing centrifugal separation, adding water into a solid mixture, crushing sludge cells by using ultrasonic, performing centrifugal separation, and taking supernatant; and adding epsilon-polylysine, ascorbic acid, ammonium molybdate, methylene succinic acid and diethyl aminoethyl hexanoate, and uniformly stirring to obtain the activated sludge spray-type fertilizer. According to the fertilizer prepared through adopting the method, toxic components are effectively removed from the activated sludge, and polysaccharides, proteins, trace elements, a variety of minerals and other nutrients are extracted from the sludge; and by matching with other components, the activated sludge spray-type fertilizer can regulate the balance of plant nutrients, enhance the disease resistance of plants and has the effect of inhibiting harmful bacteria. |
