Embodiment 1
[0025] A section of the river has a length of 2648m and an area of 60,000m 2 , storage capacity 75,000 m 3 , mainly rainwater, surface water, and groundwater, and the main functions of the water body are flood control and landscape. Every summer, because a large amount of rainwater and sewage flow into the river, the water body is very prone to algal blooms. The anti-algae agent described in this patent is used to prevent and control water body blooms. Among them, isothiazolinone, dichloroisocyanurate or trichloroisocyanurate, polyhexamethyleneguanidine hydrochloride and The mass ratio of inorganic salts is 0.5% to 1%: 1% to 2.5%: 0.05% to 0.5%: 0.0001% to 0.001%, and the amount of 0.01kg per cubic meter of water is added once every 10 days. Dilute 1 to 5 times with river water and spray evenly on a boat. During operation, control the speed of the boat at 10-15km / h, and control the flow rate of the water pump at 10-15t / h. The mass ratio of isothiazolinone, dichloroisocya...
Embodiment 2
[0027] A section of the river has a length of 2600m and an area of 70,000m 2 , storage capacity 130,000 m 3 , mainly reclaimed water and rainwater, and the main functions of the water body are flood control and landscape. Every summer, because a large amount of rainwater and sewage flow into the river, the sludge at the bottom of the river is seriously silted up, which makes the water body prone to large-scale algal blooms. The anti-algae agent described in this patent is used to prevent and control water body blooms. Among them, isothiazolinone, dichloroisocyanurate or trichloroisocyanurate, polyhexamethyleneguanidine hydrochloride and The mass ratio of inorganic salts is 1% to 2.5%: 0.5% to 1.5%: 0.2% to 0.5%: 0.0005% to 0.005%, and the amount of 0.05kg per cubic meter of water is added every 10 days. Dilute 1 to 5 times with river water and spray evenly on a boat. During operation, control the speed of the boat at 10-15km / h, and control the flow rate of the water pump ...
