Method for controlling alga pollution of water body at water intake of water plant

Abstract

The invention relates to a method for controlling alga pollution of a water body at a water intake of a water plant. The method is characterized in that a surface aerator or an artificial fountain is provided at the water intake of a water plant and is started for water spraying as needed. According to the method provided in the invention, since water is sprinkled onto the surface of a water body through arranging the surface aerator or the artificial fountain and starting the surface aerator or the artificial fountain for water spraying as needed, overgrowth of algae at a water area around the water intake can be effectively avoided, and blue algae generated in the surrounding water area are prevented from entering, thereby avoiding the influence on the quality of drinking water by harmful blue algae entering into a water purification procedure of the water plant; furthermore, sprayed water allows the temperature of surface water of the water body to be decreased to some extent, thereby reducing propagation of algae in the water body at the water intake. The method in the invention has the advantages of a simple design, convenient operation, high feasibility, low cost, easy popularization and an obvious control effect.

Description

technical field

[0001] The invention relates to a method for preventing and controlling algae, in particular to a method for preventing and controlling algae pollution in water intakes of water plants. Background technique

[0002] The environmental problems caused by the cyanobacteria outbreaks caused by the eutrophication of water bodies have attracted more and more attention from the society, but the effect of many efforts is limited. The problem of cyanobacteria control is still serious.

[0003] Throughout the domestic and foreign measures to control cyanobacteria outbreaks, there are mainly the following types, and now we will introduce and evaluate their deficiencies or mistakes one by one:

[0004] 1. Biological Control Law. Cyanobacteria are the food of freshwater fish, so it is possible to control algae and prevent algae outbreaks by releasing such fry. Cyanobacteria itself is the food of freshwater fish, but if the water bloom is seriously polluted, the fish c...
