Biological method for improving transparency of closed type small and micro water body

Abstract

The invention discloses a bioremediation method for improving the transparency of a closed type small and micro water body, and particularly relates to the technical field of ecological remediation. The method comprises the following specific steps: 1, reducing the density of fishes in the water body, and reducing or removing native plants; 2, adding clams and potamogeton crispus stone buds to carry out turbidity reduction treatment on the water body; 3, recycling part of clams through a floating type ecological treatment device, and adding snails at the same time; 4, planting dwarf vallisneria natans; and 5, potting a small number of ornamental floating-leaved plants, and adding silver carp and bighead carp to improve the attractiveness of the water body. The water body is subjected to rapid turbidity reduction by using specific biological species and addition modes, and meanwhile, a stable and attractive ecological system is constructed according to the characteristics of the closed small water body, so that the pollution of chemical agents to the water body is avoided, the restoration speed of the transparency of the water body can be ensured, and meanwhile, the long-term clarity of the water body after the water body is restored is ensured.

Description

technical field [0001] The invention discloses a biological method for improving the transparency of closed micro-water bodies, and specifically belongs to the technical field of ecological restoration. Background technique [0002] Closed small and micro water bodies mainly refer to ponds and artificial lakes that are formed naturally or artificially. At present, the water quality of most closed water bodies has reached the standard of surface water level V or above, but some water bodies still have high concentrations of suspended solids and low transparency. In this type of water body, sunlight cannot penetrate into the bottom of the water, and aquatic plants cannot grow, which seriously affects residents' perception of this type of water body. [0003] Biosorption is currently a commonly used method to improve the transparency of water bodies. Generally, benthic animals such as snails and mussels are put in to improve the transparency of water bodies, and then submerged ...
