| titleOfInvention | Sludge low-temperature drying pretreatment agent and preparation method and use method thereof |
| abstract | The invention relates to sludgeThe low-temperature sludge drying pretreatment medicament comprises the following components in percentage by mass, Fe 2 (SO4) 3 ：5%‑15%；Al 2 (SO4) 3 ·18H 2 O：10%‑20%；MnSO 4 ：1%‑5%；Na 4 P 2 O 7 ·10H 2 O：0.1%‑1%；H 2 O 2 : 25% -40%; the balance being water. The sludge low-temperature drying pretreatment agent can destroy the micelle structure of sludge before low-temperature drying of the sludge, so that bound water in the sludge is converted into free water, organic matters in the sludge can be decomposed, and gaps are formed among sludge particles, so that water in the sludge is easier to remove, and the subsequent low-temperature drying efficiency of the sludge is improved. |
