Embodiment 1
[0018] Weigh 650kg of sludge, 150kg of quicklime, 40kg of sodium hydrogen phosphite, 120kg of montmorillonite powder, and 40kg of crystal powder.
[0019] Transfer the sludge to the mixer, then add quicklime and sodium hydrogen phosphite to stir and sterilize, stir evenly and let it stand for 45 minutes, then add montmorillonite powder and stone crystal powder, stir again, transfer to the dryer and heat until 100°C, cooling, and discharge to obtain sludge paddy field water purifier.
Embodiment 2
[0021] Weigh 750kg of sludge, 120kg of quicklime, 80kg of montmorillonite powder, 30kg of crystal powder, and 20kg of sodium hydrogen phosphite.
[0022] Transfer the sludge to the mixer, then add quicklime and sodium hydrogen phosphite to stir and sterilize, stir evenly and let it stand for 45 minutes, then add montmorillonite powder and stone crystal powder, stir again, transfer to the dryer and heat until 100°C, cooling, and discharge to obtain sludge paddy field water purifier.
Embodiment 3
[0024] Weigh 600kg of sludge, 200kg of quicklime, 100kg of montmorillonite powder, 60kg of crystal powder, and 40 parts of sodium hydrogen phosphite.
[0025] Transfer the sludge to the mixer, then add quicklime and sodium hydrogen phosphite to stir and sterilize, stir evenly and let it stand for 45 minutes, then add montmorillonite powder and stone crystal powder, stir again, transfer to the dryer and heat until 100°C, cooling, and discharge to obtain sludge paddy field water purifier.
[0026] Observation through probation, paddy field water settling velocity is all between 15-40 minutes, and embodiment 1 is optimal formula.

Abstract
The invention provides a rice field water purifying agent with sludge as a matrix and relates to the technical field of sewage treatment. The water purifying agent is prepared from 500-650 parts of sludge, 50-150 parts of quick lime, 50-150 parts of montmorillonite powder, 20-50 parts of crystal powder and 20-35 parts of sodium hydrogen phosphite. The water purifying agent has the advantages that the characteristics of fast adhesion settling of the sludge and the sludge containing rich plant auxin are adopted and combined with the quick lime for sterilization and deodorization, sodium hydrogen phosphite is used for activating lime ions, the sterilizing effect of the lime can be better, pesticide residues in the sludge can be removed, by the cooperation with the montmorillonite powder and the crystal powder, total suspended solids in water in a rice field can be eliminated thoroughly, a fertilizer mixture mixed and dissolved in the water can be wrapped to deposit on the water bottom, when it rains, the fertilizer mixture can not run off along with rainwater, nutrients of the sludge can support growth of rice seedlings, and the quick lime in the composition has an inhibition effect of rice blast. The water purifying agent is used in the dry field, can preserve moisture, resist disasters and improve soil, and plays important roles in sludge return to the field, sludge water purification and country ecology scene protection and restoration.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a paddy field water purifying agent with sludge as a matrix and a preparation method thereof. Background technique [0002] Eliminating water pollution is an important task for people in the world today. The source of pollution that people pay attention to is the discharge of industrial and mining enterprises, which pollutes water bodies. Few people know about the use of chemical fertilizers and pesticides in agricultural farming to pollute water bodies. In recent decades, agricultural cultivation has adopted clean fertilization, heavy chemical fertilizers, and light organic fertilizers. In order to achieve high yields and harvests, excessive fertilization and excessive use of pesticides have been used in rice field cultivation. Chemical fertilizers and pesticides are mixed in water bodies. When exposed to sunlight, paddy fields are flooded It is black and smelly. When i...
