Embodiment 1

[0023] Embodiment 1: a kind of method of repairing and controlling eutrophic water body, comprises the following steps:

[0024] 1) Interception treatment of exogenous phosphorus and nitrogen nutrients input;

[0025] 2) Purification treatment of sediment enriched with endogenous phosphorus and nitrogen nutrients;

[0026] 3) Dialysis treatment of water body.

[0027] In step 1), according to different types of exogenous pollution sources, divide different pollution source plates, and use integrated equipment to remove phosphorus and nitrogen nutrients in them.

[0028] The main reactant used in the integrated treatment equipment is a ceramsite material with multiple micro-electrochemical functions including electrolysis reaction, physical adsorption, and water electrolysis, electrocatalysis, and electrode reaction derived therefrom. Functional ceramsite is composed of the following ingredients: 15% potassium aluminum silicate, 20% layered aluminosilicate, 6% boron-containin...

Abstract

The invention discloses a method for repairing and treating a eutrophic water body, which adopts a multi-unit and multi-layer technical system for repairing and treating the eutrophic water body by sewage interception treatment of exogenous phosphorus-nitrogen nutrient substance input, purification treatment of endogenous phosphorus-nitrogen nutrient substance enriched bottom mud and dialysis treatment of the water body. And the method has the relative advantages of low energy consumption, low influence, low cost, easiness in maintenance and low secondary pollution risk.

Description

technical field [0001] The invention belongs to the technical field of water ecological environment protection, and in particular relates to a method for repairing and treating eutrophic water bodies. Background technique [0002] The pressure of eutrophication control in slow-flowing and stagnant waters such as rivers, seas, lakes, and reservoirs has remained high. The main cause of the eutrophication in the waters is the result of rapid enrichment and obvious excess of man-made nitrogen and phosphorus in the water body and sediment. Among them, phosphorus is usually the culprit, which is necessary for the synthesis of algae and other cells Nutrient elements are also important components of nucleic acid, fat, and protein, and play an irreplaceable and important role in the energy metabolism process. A serious consequence directly caused by the eutrophication of the water body is: the proliferation of aquatic plants mainly composed of algae, which greatly weakens the transp...
