The invention discloses a bulge light spot type water surface oil stain adsorption patch, which belongs to the field of sewage treatment. According to the bulge light spot type water surface oil stainadsorption patch, along with the prolonging of oil stain adsorption time, an oil decomposition layer outside a curled water guide ring is gradually dissolved, so that an adsorption soft layer extendsand a balance weight sinking ball can be in contact with water. at the moment, water enters a semi-permeable wrapping layer along a water guide soft rod and a water guide soft rod and can generate gas after making contact with the gas overflow particles; on one hand, the outer bulge patch can bulge, on the other hand, part of the gas overflows towards the water surface, and then the adsorption patch can be driven to float on the water surface at a high speed; therefore, the position of the adsorption patch can be automatically changed, the situation that the adsorption efficiency is reduced due to the fact that oil stains at the same position are reduced is effectively avoided; meanwhile, after bulging, a self-shading air overflowing ball is matched to emit light, workers can be conveniently reminded in time to recycle the adsorption patch, a novel adsorption patch is put in, and the oil stain adsorption efficiency is improved.
