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.
