Silver carp, bighead carp, grass carp, cladophora and daphnia hyaline cooperated algae control method

Abstract

The invention discloses a method for synergistically controlling the algae of silver carp, bighead carp, grass carp, Trichophyton algae and Phyllostachys vulgaris, which relates to a water treatment method. The invention solves the problems that the transparency of the water body decreases and the water quality deteriorates due to the excessive growth of algae in the water. The steps of the invention for controlling algae are as follows: stocking silver carp, bighead carp and grass carp in the eutrophic water body and constructing a floating cage; the nylon wire mesh in the floating cage is attached and grown with Phytolithiasis, and the floating cage is grown with transparent fleas . The method of the invention is easy to operate, has high efficiency, is economical, quick, and easy to manage, and can be popularized and applied on a large scale. The phosphorus removal rate of the invention is 60-66%, the average removal rate of algae is 68-73%, and the average removal rate of chlorophyll a in effluent is 63-66%.

Description

technical field [0001] The invention relates to a water treatment method, and more specifically relates to a method for synergistically controlling algae content in eutrophic raw water of water plants by utilizing various freshwater aquatic organisms, which is suitable for eutrophic high algae raw water of water plants. Background technique [0002] Eutrophication of water body is a water body effect caused by excessive input of nutrients such as nitrogen and phosphorus. It is mainly manifested in the excessive growth of algae in water, accompanied by a series of changes in water quality and water ecology, resulting in a decrease in water transparency and deterioration of water quality. Eutrophication and high algal raw water greatly affect the normal production of waterworks. [0003] The existing algae removal methods in water treatment mainly include: dosing chemical agents to remove algae, microfiltration to remove algae, air flotation to remove algae, microorganisms to ...
