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.
