Problems solved by technology

[0006] In the prior art, submerged plants have been combined with natural red soil to restore phosphorus in situ in sediments, but there are few explorations on the factors that affect the combined restoration, such as light factors, so the restoration effect is not significant

Embodiment 1

[0040] see figure 1 and figure 2 , a restoration method for controlling water pollution, including submerged plants, red soil, sediment and experimental control bottles, red soil is a natural material, easy to obtain, and low in cost, so this method is technically economical and feasible, and the sediment is put into The bottom of the experimental control bottle forms the sediment layer 2, and then lays red soil on the surface of the sediment layer 2 to form the red soil covering layer 3, and then implants the roots of submerged plants in the red soil covering layer 3 to form the submerged plant layer 4, and the experimental control bottle includes the experimental cup The body 1 and the light control mechanism, the light control mechanism is connected to the lower end of the experimental cup body 1, and the experimental control bottle is equipped with a cup cover 5, and the cup cover 5 is made of an opaque material;

[0041] see figure 2 and image 3 , the light control ...

Abstract

The invention discloses a restoration method for water pollution control, and belongs to the technical field of in-situ remediation. The restoration method for water pollution control involves submerged plants, red soil, sediments and an experimental control bottle, wherein the sediments are put into the bottom of the experimental control bottle to form a sediment layer, then the red soil is laidon the surface of the sediment layer to form a red soil covering layer, then the roots of the submerged plants are planted into the red soil covering layer to form a submerged plant layer, the experimental control bottle comprises an experimental cup body and a light control mechanism, light can affect the functions of photophilous microorganisms and photophobic microorganisms in the red soil covering layer, the functions of the microorganisms are one of important factors affecting in-situ remediation of sediment phosphorus through the combination of the submerged plants and natural red soil,and therefore, the in-situ remediation of the sediment phosphorus through the combination of the submerged plants and natural red soil is further explored and researched by controlling the light, so that the optimal effect of the in-situ remediation is achieved.

Description

technical field [0001] The invention relates to the technical field of in-situ restoration, and more specifically relates to a restoration method for controlling water body pollution. Background technique [0002] Phosphorus is one of the essential nutrient elements for organisms. It is closely related to life activities and is also a limiting element for the growth of aquatic organisms. Nutritization process is closely related (Huang Qinghui et al., 2006). It is generally believed that when the concentration of TP is 0.02mg / L, it is the critical concentration value that causes eutrophication of water body. Excessive phosphorus in water will increase the primary productivity of freshwater aquatic ecosystems, lead to eutrophication of water bodies, and then bring negative impacts on aquatic ecosystems (Baie et al., 2009). Sediment is the accumulation site of natural water pollution (ZhangBetal., 2012). When exogenous pollution is reduced or cut off, the release of phosphoru...
