Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water environment treatment, and in particular to a hydrological environment treatment device. BACKGROUND

[0002] In the treatment of hydrological environment, salvaging algae is a crucial intervention measure, and its core purpose is to curb the process of eutrophication of water bodies and repair the imbalanced aquatic ecosystem. When excessive accumulation of nutrients such as nitrogen and phosphorus in water bodies, blue-green algae, green algae, filamentous algae and other algae will reproduce wildly, forming "water bloom" or "algal bloom", which seriously destroys the ecological balance. Algal blooms not only directly block the sunlight from penetrating, but also lead to the death of underwater plants due to insufficient photosynthesis, which further reduces the dissolved oxygen content of water bodies and threatens the survival of aquatic organisms such as fish. At the same time, some algae species (such as microcystis) also release algal toxins, pollute water sources, and directly affect the safety of drinking water for humans and animals and public health. Through timely salvage, excessive nutrients and organic matter in water bodies can be directly removed, effectively reducing the internal pollution load and preventing secondary pollution caused by the decomposition of algal residues.
