Abstract

The invention discloses a water treatment method for oxidation algae removal with high-activity singlet oxygen, and relates to methods for algae removal. The problems that in a pre-oxidization (chlorine and ozone) algae removal method, equipment needs to be additionally arranged, the operation is complex, and poisonous and harmful by-products are easily produced are solved. The water treatment method for the oxidation algae removal comprises the steps that solid bleaching powder and inorganic solid peroxide are added to water with algae, stirring is carried out, and coagulation, precipitation, filtration and disinfection are carried out in sequence. Hypochlorite ions provided by the bleaching powder in the method for the algae removal fast react with hydrogen peroxide released after the peroxide is dissolved in water to generate the high-activity singlet oxygen, algae cells can be fast killed, algae inactivation is achieved, and the aim of the algae removal is achieved. The high-activity singlet oxygen can be directly added for use as a solid reagent, equipment does not need to be additionally arranged, the operation is simple and easy to carry out, transport and storage are convenient, the poisonous and harmful by-products are not produced, and the method can be applied to water plants in a large scale and is more suitable for emergency treatment in the algae large-scale bloom process.

Description

technical field

[0001] The invention relates to a method for removing algae. Background technique

[0002] In recent years, the algal blooms caused by the eutrophication of rivers, lakes and seas have attracted widespread attention from all walks of life. The flooding of algae not only affects the water landscape and normal production of aquaculture, but also poses a threat to the living environment of human beings.

[0003] Algae and its by-products have brought many adverse effects to the traditional water purification process: (1) causing the deterioration of water quality and causing disgusting smell and taste in drinking water; (2) the death of algae sinking to the bottom to form humus, increasing the water (3) Algae and its soluble metabolites are the precursors of chlorination disinfection by-products; (4) The turbidity formed by algae has high stability, small specific gravity, and is difficult to remove Heavy, not easy to remove in coagulation sedimentation, unremo...
