A method of treating liquid animal manure comprising contacting a manure slurry with a treatment composition comprising a treatment effective amount of AlCl3.cndot.nH2O or Al(NO3)3.cndot.mH2O, or the residue of AlCl3.cndot.nH2O or Al(NO3)3.cndot.mH2O, to form a resulting slurry, wherein n is from 0 to 10, and m is from 0 to 12. The treatment effective amount is effective to reduce phosphorus solubility in the manure; reduce phosphorus runoff and/or phosphorus leaching from fields fertilized with manure; inhibit ammonia volatilization from the manure; flocculate solids in the manure; reduce pathogens in the manure; increase the nitrogen content in the manure; and/or reduce acid rain and PM-10s associated with the manure.
Méthode de traitement de déchets liquides d'origine animale qui consiste à mettre en contact des suspensions de déchets avec une composition de traitement comprenant une quantité efficace de AlCl3.cndot.nH2O ou de Al(NO3)3.cndot.mH2O, ou le résidu de AlCl3.cndot.nH2O ou de Al(NO3)3.cndot.mH2O, pour former une bouillie résultante, dans laquelle n varie de 0 à 10 et m varie de 0 à 12. La quantité efficace de traitement permet de réduire la solubilité de phosphore dans le fumier; réduire le ruissellement de phosphore et/ou le phosphore découlant des champs fertilisés avec du fumier; inhiber la volatilisation de l'ammoniac à partir du fumier; floculer des matières solides dans le fumier; réduire les pathogènes contenus dans le fumier; augmenter la teneur en azote dans le fumier; et/ou réduire la pluie acide et les PM-10 associés au fumier.
