Embodiment 1
[0029] (1) Add saturated sodium carbonate solution to the bottom mud of the black and odorous water body, and the amount of saturated sodium carbonate solution is 500ml / m according to the bottom area of the bottom mud 2 . Inject evenly into the bottom mud by continuous spraying.
[0030] (2) First mix sodium silicate, sodium percarbonate and water into a sodium percarbonate preparation solution in a weight ratio of 1:2:100, and then mix manganese dioxide and sodium percarbonate preparation solution in a weight ratio of 0.5:80 , made of sodium percarbonate liquid.
[0031] Add sodium percarbonate liquid to the bottom mud of black and odorous water bodies. The amount of sodium percarbonate liquid used is calculated according to the thickness of the bottom mud layer. When >5cm, use 1600ml per square meter. Inject evenly into the bottom mud by continuous spraying.
[0032] (3) Add trichloroisocyanuric acid to black and odorous water, add 1 kilogram of trichloroisocyanuric ac...
Embodiment 2
[0035] (1) Add saturated sodium carbonate solution to the bottom mud of the black and odorous water body, the amount of saturated sodium carbonate solution is 650ml / m according to the bottom area of the bottom mud 2 . Inject evenly into the bottom mud by continuous spraying.
[0036] (2) First mix sodium silicate, sodium percarbonate and water into a sodium percarbonate preparation solution in a weight ratio of 1.2:2.5:130, then mix manganese dioxide and sodium percarbonate preparation solution in a weight ratio of 0.7:90 , made of sodium percarbonate liquid.
[0037] Add sodium percarbonate liquid to the bottom mud of black and odorous water bodies. The amount of sodium percarbonate liquid used is calculated according to the thickness of the bottom mud layer. When >5cm, use 1300ml per square meter. Inject evenly into the bottom mud by continuous spraying.
[0038](3) Add trichloroisocyanuric acid to the black and odorous water body, add 2 kilograms of trichloroisocyanur...
Embodiment 3
[0041] (1) Add saturated sodium carbonate solution to the bottom mud of the black and odorous water body, the amount of saturated sodium carbonate solution is 800ml / m according to the bottom area of the bottom mud 2 . Inject evenly into the bottom mud by continuous spraying.
[0042] (2) First mix sodium silicate, sodium percarbonate and water into a sodium percarbonate preparation solution in a weight ratio of 1.5:3:150, and then mix manganese dioxide and sodium percarbonate preparation solution in a weight ratio of 1.0:100 , made of sodium percarbonate liquid.
[0043] Add sodium percarbonate solution to the bottom mud of black and odorous water bodies. The amount of sodium percarbonate solution is calculated according to the thickness of the bottom mud layer. The specific dosage is: when the thickness of the bottom mud layer is ≤ 5cm, the dosage is 600ml per square meter; When >5cm, use 1000ml per square meter. Inject evenly into the bottom mud by continuous spraying. ...
