Method and algaecide for treating algae bloom by strong-flocculation magnetic polymer

Abstract

The invention discloses a method of algae bloom through strong flocculate magnetic polymers and algaecide, which comprises the following steps: using strong flocculate nature of polyaluminium chloride ferric; mixing with hyper pure magnet power; getting magnetic strong flocculant suspension; putting into water body environment with rich of algae, nitrogen and phosphor; flocculating algae cell quickly; absorbing nitrogen and phosphor; forming big block dense flocculate body; using magnetic response property of super pure magnetic iron ore power; enriching algae cell under the function of foreign field; transporting out of water body area.

Description

Technical field [0001] The invention belongs to the field of environmental protection, in particular to a method for treating algae blooms with a flocculating magnetic polymer and an algae removing agent. Background technique [0002] In recent years, the occurrence and development of marine blooms in rivers and lakes in our country have attracted widespread attention from all walks of life. Large-scale blooms have severely disrupted the balance and stability of aquatic ecosystems, not only affecting the water landscape, but also affecting the aquaculture industry. The development of algae, and the toxicity of algae has constituted a threat to the human living environment. The economic losses caused by red tides to the coastal areas alone amount to billions of dollars each year, so the outbreak of algae has become a disaster. The main nutrient elements that cause algal blooms are nitrogen and phosphorus in the water body, especially phosphorus, which plays a key role. At present,...

Problems solved by technology

However, such methods often require a huge investment in artificial engineering in advance to create and control the conditions for aquatic plants (such as submerged plants to survive in low transparency or lack of suitable bottom mud) or animal survival conditions required to suppress algal blooms, so they are effective. Slow, high cost, difficult to be generally applicable to the treatment of large areas and sudden algal blooms

[0006] Although the above methods can relieve algae blooms to a certain extent, they have a common shortcoming - the effect of phosphorus removal is not obvious, and cannot solve the key problem of algal bloom outbreaks.

[0007] In response to this problem, a method of algae removal with fast collection and low cost has been invented by the application. This technology can not only effectively absorb and flocculate algae, but also quickly remove the algae from the water body through the action of an external magnetic field. The removal effect is very significant, and both symptoms and root causes can be treated, but this method is not fast enough for flocculation, and the flocs formed are not dense enough, which is not conducive to the subsequent magnetic separation work.
