Problems solved by technology

The problem of the bottom mud covering technology is that the engineering volume is large, a large amount of clean sediment is required, and the source is difficult
Its limitation is that the periodical growth of microorganisms leads to slow effect of the technology, and the complexity of the environment leads to the failure of microorganisms to survive and culture failure

Embodiment 1

[0038] refer to figure 1 , an in-situ restoration blanket of riverbed bottom mud, comprising a bottom mud restoration layer 1, an aquatic plant layer 2 and a matrix layer 3, the bottom mud restoration layer 1 is used for repairing the riverbed bottom mud, and the aquatic plant layer 2 is used for the restoration of the riverbed water body Purification and restoration, the combination of the two can effectively shorten the period of river bed sediment restoration and improve the effect of restoration.

[0039] The restorative agent layer includes EM strains, brown sugar, honey, agricultural sludge, and clay, wherein the proportion of each component is 0.03% of EM strains, 0.06% of brown sugar, 0.015% of honey, and 15% of agricultural Sludge, remaining clay. Brown sugar and honey are used to activate EM strains for growth, agricultural sludge is used as a substrate for the growth of EM strains, and clay is used to mix other components and adhere to the supporting framework.

Abstract

The invention discloses a riverbed sediment in-situ remediation blanket which comprises a sediment remediation layer, an aquatic plant layer and a matrix layer. The matrix layer is fixedly arranged onthe sediment remediation layer, and the aquatic plant layer grows on the matrix layer; the sediment remediation layer comprises a supporting framework and a remediation agent layer wrapping the supporting framework. The invention further provides a riverbed sediment remediation method. Secondary pollution caused by riverway dredging can be effectively avoided, meanwhile, damage to ecological balance of sediment is avoided, a silt layer is reduced, the reservoir capacity of a riverway water body is increased, purification of riverbed sediment is improved, and therefore the effects of shortening the treatment period and obviously improving riverbed sediment remediation are achieved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, in particular to an in-situ restoration blanket for riverbed bottom mud and a riverbed bottom mud restoration method. Background technique [0002] At present, the phenomenon of black and odorous water bodies in many cities is relatively serious, and cannot be effectively treated. Even if the treatment reaches the standard in a short time, there will be recurrences. caused by harmful substances. [0003] Sediment, as one of the three environmental elements (water quality, aquatic organisms and sediment) of the aquatic ecosystem, undertakes the dual functions of receiving exogenous pollutants and releasing nutrients into the water body, and plays a vital role in the material cycle and energy of the aquatic ecosystem. important role in the flow process. The sediment is composed of a large amount of nutrients (nitrogen, phosphorus, organic matter, etc.), with its continuous accumul...
