Active sludge preprocessing agent, preparation method and application method thereof
2015
The invention relates to an active sludge preprocessing agent, a preparation method and application method thereof. The active sludge preprocessing agent comprises the following components in percentage by weight: 22 to 38% of water hyacinth fresh leaf fermented sludge, 0.3 to 4% of modified water hyacinth fiber, 0.2 to 1% of sodium acetate, 0.01 to 0.06% of nano titanium dioxide, and the balance being zeolite powder. The active sludge pretreatment is innovatively added, an active sludge preprocessing agent is added; through the technology, the activity of phosphorus-accumulating bacteria is activated, the resistance is enhanced; the chance of choosing excellent strains is increased; through the simple pretreatment, the post strain screening technology is simplified; and the technology has a wide application range and is especially suitable for phosphorus pollution treatment in in-situ river channel restoration.
