Method for repairing black and odorous inferior V-type water body

Abstract

The invention discloses a method for repairing a black and odorous inferior V-type water body. The method comprises the following steps: adding sodium hypochlorite into the black and odorous inferiorV-type water body; putting cloth which is treated by a front-end biological rope and is used for reducing nutritive salt in the black and odorous inferior V-type water body into the black and odorousinferior V-type water body; and planting the submerged plants in the black and odorous inferior V-type water body. The sodium hypochlorite can reduce the turbidity of the water body; transparency is improved, the sunlight irradiates into a water body, normal photosynthesis of submerged plants is guaranteed, after nutritive salt is reduced through the cloth treated through the front-end biologicalrope, an attachment carrier is provided for growth of beneficial microorganisms in the water body, biomass is improved, the beneficial microorganisms are not prone to loss in water, and generation continuity of the beneficial microorganisms is guaranteed; a biological membrane formed on the surface of the biological rope carrier is absorbed and assimilated by taking pollutants in river water as nutrition, so that the biological membrane has a relatively strong purification effect on pollutants in a water body, the survival rate of aquatic plants can be simply and effectively improved, the labor cost is reduced, and the growth stability of the aquatic plants is enhanced.

Description

technical field [0001] The invention belongs to the technical field of water body ecological environment treatment, and in particular relates to a method for repairing black, smelly and inferior Class V water bodies. Background technique [0002] In the practice of ecological environment management of lakes or rivers, the most commonly used measure is to use submerged plants to control, which must ensure the effective growth of submerged plants and gradually form a stable ecosystem. The most important thing is to maintain the animals in the environment. Plant balance and boundary conditions that control its growth and reproduction, such as water turbidity and dissolved oxygen conditions, light intensity, nutrients, sediment properties, water flow velocity and water depth, temperature, pH value, heavy metals, and the impact of animals and plants, etc. However, there is currently no effective method for repairing black, smelly and inferior Class V water bodies, because the exi...
