A Coupled Floating Device Using Slow-release Algicide to Control Algae Bloom

Abstract

The invention provides a coupled floating body device for preventing and controlling water bloom by utilizing a slow-release algal inhibition agent. The coupled floating body device structurally comprises a single floating body. The single floating body comprises gauze elements, a plurality of hemispherical purifying balls, a fixing rod and a floating body main frame. A hanging ring A is installedon two sides of each hemispherical purifying ball respectively, hanging rings B and hooks are arranged on the floating body main frame, the hemispherical purifying balls are fixed to the fixing rod through the hanging rings A, two ends of the fixing rod penetrate through the hanging rings B to be hung on the floating body main frame, and the gauze elements are located in the hemispherical purifying balls. The coupled floating body device has the advantages that dismounting is simple, flexible and quick, and the device can be dragged to any area of a water body as required and has good maneuverability; the algal inhibition efficiency is high, the duration time is long, and the ecological safety is high; full contact between the algal inhibition agent and algae on the surface layer of the water body is ensured, diffusion of the algal inhibition agent is facilitated, and the influence of bottom mud attachment on the algal inhibition effect is avoided; the algal inhibition agent is convenient to supplement and update and meets the long-term water bloom prevention and controlling demand.

Description

technical field [0001] The invention relates to a coupling floating device for preventing and controlling algal blooms by using a slow-release algae inhibitor, which belongs to the field of water body pollution control. Background technique [0002] The eutrophication of water bodies in recent decades has led to large-scale algae blooms in water bodies, water body function decline, water ecosystem imbalance, biodiversity decline, and even directly affect the safety of drinking water sources, posing a threat to ecosystem stability and human health. Therefore, how to effectively suppress algal blooms is a hot topic in current research. [0003] Among the control methods of numerous cyanobacterial blooms, phytoallelopathic algae inhibitors have become a research hotspot in the field of water pollution restoration due to their advantages of convenient application, good algae inhibition effect, and high ecological safety; Algae inhibitory performance and influencing factors have...

For example: Patent Application No. 201110129482.7 discloses the use of pure artemisinin as an algae inhibitor, which has the characteristics of good environmental affinity and quick effect. The ingredients lose rapidly, sink, and are covered by the bottom mud, and the effective algae-inhibiting ingredients are difficult to diffuse, which seriously affects or even completely loses the algae-inhibiting effect, and cannot effectively control the growth of algae on the surface of the water body; patent application No. 201610969517. The preparation and use method of algae agent, the three substances of gallic acid, nonanoic acid and ethyl 2-methyl acetoacetate are embedded in sodium alginate in proportion to make a slow-release algae inhibitor, which is packed into In the net bag, the net bag is hung on the artificial floating island. Although this patent application solves various defects of direct dosing of algae inhibitors, artificial floating islands must be placed in areas with severe algae bloom outbreaks during application, and the mobility is very poor. Difficult to replace; therefore, there is an urgent need to develop a new type of algal bloom control device that is highly mobile, easy to use, environmentally friendly, not inhibited by sediment, and convenient to replace and replenish algae inhibitors
