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 ...

Abstract

The invention discloses a method used for treating urban river and lake algal bloom, and especially relates to a formula of an algae inhibitor, and an application method thereof. The algae inhibitor is a water solution of isothiazolone, dichloroisocyanurate or trichloroisocyanurate, polyhexamethyleneguanidine chloride, and inorganic salt. The mass ratio of the materials is 0.5%-5%:0.1%-2.5%:0.05%-1%:0.0001%-0.005%. During a flood season, the algae inhibitor is added to a water body requiring treatment every 3-15 days; when rainfalls such as a moderate rain or a more severe rain occur, the addition frequency is appropriately increased. The dosage amount of the algae inhibitor is 0.002-0.05kg/m<3> each time. With the algae inhibitor and the application method provided by the invention, algae amount in water bodies can be effectively reduced, and occurrence of algal bloom can be effectively avoided.

Description

technical field [0001] The invention belongs to the field of treatment of urban rivers and lakes, and in particular relates to an algae inhibitor for controlling water blooms in urban rivers and lakes and a method for using the same. Background technique [0002] With the rapid growth of my country's economy, environmental problems have become increasingly severe. In recent years, due to the influence of many natural and human factors, the nutrients discharged into lakes and reservoirs have continued to increase, resulting in aggravated eutrophication of water bodies, which in turn led to algal blooms in various water bodies. Outbreaks are becoming more frequent and larger. Severe algal blooms will cover the water surface, prevent photosynthesis in the water body and its exchange with the atmosphere, rapidly reduce the concentration of dissolved oxygen in the water, cause the death of aquatic animals and plants, and damage the ecology and surrounding environment. At the same...
