Description
Technical field
The present invention relates to water treatment field, specifically, the present invention relates to a kind of green without phosphorous
Environmental protection slow-release scale inhibitor.
Background technology
Antisludging agent is a kind of chemical agent being prevented from incrustation scale generation or suppressing its deposition growing.
The inorganic agent major part of the cooling water being currently used for open type system belongs to phosphorus line formulation, but phosphorus
Discharge can cause the eutrophication of water proximate, promotes microorganism particularly algae excessive propagation,
Cause the harm such as lake water spray, red tide of sea.Water is the primary condition that the mankind depend on for existence, but
Water resource is limited in the world.The water yield per capita of China be only world's water yield per capita four/
One, water resource is the poorest.Along with the high speed development of industry, the ecological balance of water is increasingly subject to
Heavy damage.For solving water resources crisis, adapt to sustainable development, it is necessary to rationally economize on
Water.Cooling water amount in water for industrial use accounts for 60-80 weight % of total water consumption, therefore, joint
The about main target of water for industrial use is to recycle cooling water, improves recycling as much as possible
Rate, reduces blowdown simultaneously.But during cooling water uses, along with constantly circulating and concentrating,
The content of water mineral also can be continuously increased, and exacerbates pipeline and equipment corrosion is asked with fouling
Topic；It addition, water is as the supplementary water of recirculated cooling water, this water in the use of the most a lot of power plant
Middle inorganic salt content is high, content of organics height is prone to bacterium algae propagation, so must be toward cooling down in water
Add antibacterial and the corrosion inhibiting and descaling agent quality with improvement cooling water, thus ensure that equipment is transported safely
OK, but these chemical agents can increase the phosphorus content in recirculated water, causes discharge limited,
As being put in the middle of environment, can weighting ring environment pollution, simultaneously the adding to increase and make of two kinds of medicaments
Use cost.
Summary of the invention
The technical problem to be solved is to provide a kind of the most phosphorous, component safety and environmental protection
High efficiency corrosion inhibiting scale retardant, obtains a kind of corrosion mitigating effect by reasonably designing the formula of each material
