Description
Technical field
The present invention relates to environmental protection technical fields, are specifically related to a kind of multi-functional composite alga removing particle.
Background technique
A large amount of sanitary sewages and industrial wastewater discharge rich in N, P are pooled to ocean to rivers and lakes, make water body
Eutrophication causes algae and the rapid mass propagation of other planktonic organisms, results in serious environmental hazard, this phenomenon is in recent years
Frequently to occur in the major small lakes in China, river and sea area etc..It is logical that the mass propagation of algae not only seriously hinders the water surface
Row, and water body environment is seriously destroyed, endanger ecological environment security.
Through long-term research and practice, the main algae removal technology of three classes with physics, chemistry, biology for means is formd.
Physical method, which can be divided into, removal method and kills method, the former be directly removed by certain physical method frustule or
Its content is reduced, mainly includes water diversion and renewal, mechanical algae removement, filter out algae, air floatation alga removing and activated carbon adsorption etc. excessively；The latter is to make
The algae in water body is directly or indirectly killed with physical means, main method has shading treatment, electrolysis except algae, ultraviolet light irradiation and surpasses
Sonicated etc..Physical method can effectively remove algae, will not generate secondary pollution, but incur great expense, so can only
Local waters for small size pond and big water body.
Chemical method is mainly that chemistry kills method.Chemistry kills method generally by medicament is added, and inhibits the physiology of frustule
Function destroys the structure of frustule, and frustule inactivation is made even to disintegrate, and kills algae to reach.Major pharmaceutical agent has Strong oxdiative
Agent (liquid chlorine, hydrogen peroxide, ozone, potassium permanganate etc.), copper sulphate etc..Chemical method is good, at low cost except algae effect, but specificity
Difference, and secondary pollution is serious.
Bioanalysis utilizes microorganism, plant and animal control algae except algae refers to.Microbial method is by adding microorganism drop
Nutriment in Xie Shui, or add and bite algae microorganism and directly degrade frustule.Plant method is artificial plantation aquatic higher plants, right
Water nutrition is controlled；It on the other hand is the algae inhibited in water body by the allelochemical of Plant emission.Animal law
It is usually to put aquatic animal such as filter-feeding fish in a suitable place to breed, come the algae in water body of eating.The ecological security height of biological algae removal, cost
Low, often slow effect, action period are long, though wherein to bite algae quick for microorganism, but ecological security remains to be discussed.
Existing algicide is not thorough except dry function, and is easily polluted to water body, and the life of fish, shrimp, crab is not only unfavorable for
It is long, but also the statement of fish, shrimp, crab can be seriously threatened, and then threaten human life and health, therefore, researching and developing one kind can either be thorough
While algae is removed at bottom, moreover it is possible to reduce water pollution, effectively improve the concentration of microelement in water body, promote the health of fish, shrimp, crab
The algicide of growth is extremely urgent.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of multi-functional composite alga removing particles, and local use concentration is big, can
It is enough thoroughly to remove algae, moreover it is possible to reduce water pollution.
