Composite type inorganic polymer water quality purifier and method of magnetic gathering algae eliminating

Abstract

The invention discloses a composite inorganic macromolecule water purifying agent and a method for removing algal blooms by magnetic polymerization. The magnetic chitosan solution is prepared by first dispersing magnetic powder in a chitosan solution, and then an appropriate amount of the magnetic chitosan solution is mixed with the magnetic chitosan solution. When added to the algae liquid, the algal cells are flocculated through the dual effects of chitosan adsorption and bridging and electrical neutralization. Finally, the magnetic responsiveness of the magnetic powder is used to quickly remove harmful substances such as algae in the water body under the action of an external magnetic field. The method of the invention can quickly adsorb or neutralize harmful substances in water, improve the transparency of water body, maintain water quality stability and acid-base balance. Under the action of an external magnetic field, the algal cells are rapidly enriched, which solves the problem of salvage after algae removal and prevents the possibility of secondary pollution. At the same time, the salvaged material is biodegraded by enzymatic method, so that the magnetic powder can be separated, recycled and reused, thereby reducing the processing cost. The purifying agent has high efficiency and broad spectrum, high speed and high safety performance. Excessive input will not produce any toxic and side effects. It can completely replace various water treatment agents. It is a new type of safe and environmentally friendly green product.

Description

technical field [0001] The invention belongs to a water purifying agent (a method for removing algal blooms through magnetic aggregation), in particular to a water purifying agent for removing algae in water bodies such as rivers and lakes. Background technique [0002] In recent years, the flooding of algae in my country's rivers, lakes and seas has attracted widespread attention from all walks of life. The large-scale algae outbreak has seriously damaged the balance and stability of the aquatic ecosystem, not only affecting the water body landscape, but also affecting the development of aquaculture. And algae toxicity has constituted a threat to the human living environment. Only the economic losses caused by red tides to the coast amount to billions of yuan every year, so the algae outbreak has become a disaster. Currently more popular methods of algae removal can be roughly attributed to physical methods, chemical methods and biological methods. [0003] Physical method...

Problems solved by technology

[0007] Each of the above-mentioned algae removal methods has its own advantages and disadvantages, but the main disadvantage of clay algae removal is: only the cyanobacteria are adsorbed and settled to the bottom of the water, and the algae that fall to the bottom of the water are still alive and will still survive and survive for a certain period of time. Secondly, the algae falling to the bottom of the water are in a state of anoxic state. If they rot, they will release hydrogen sulfide gas and algal toxins, which cannot be decomposed, and will lead to benthic organisms and spores after spreading in the water body. Organisms are smothered to death, seriously causing hypoxia in the bottom mud, causing secondary pollution and biological death, and even releasing harmful gases, further destroying the biological chain of the water body, and treating the symptoms but not the root cause
