Problems solved by technology

There is basically no clean water supply for small and micro water bodies. The fluidity of the water body is poor, and most of them are "dead water".
[0003] In the existing technical examples, most of the treatment of small and micro water bodies adopts the method of engineering dredging to realize the transfer of endogenous pollution. On the one hand, the workload of dredging engineering is heavy, and the sensory experience of black and odorous sludge is poor during the implementation process. On the one hand, the whereabouts of sludge is also a big problem, and the problem of black and smelly water cannot be completely solved under the condition of incomplete sewage interception

Embodiment 1

[0055] The water body of the project is located in a landscape pond in an urban village in Tianhe District, Guangzhou City, with an area of ​​about 6000m 2 , the maximum water depth is about 3m, and the water level does not change much throughout the year. It is surrounded by residential areas, and there are a small number of catering supporting businesses. The landscape pond is made of masonry and stone revetment, which is black and smelly all the year round. Before the treatment, the water quality was turbid, algae broke out severely, a layer of oil film appeared on the water surface, and a large number of fallen leaves and sundries were floating, completely losing the landscape and ecological functions. The sources of pollution are mainly domestic sewage and initial rainwater that are not completely intercepted nearby.

[0056] According to the test results of water quality (see Table 1), all indicators exceed the Class V water standard of the Environmental Quality Standard...

Embodiment 2

[0076] In this embodiment, the landscape pond pollutants are gradually migrated and the ecological environment of self-purification of the water body is realized by means of the governance and restoration of the ecological chain. The method includes the following steps:

[0077] S21. Substrate improvement: After the first ecological water diversion, use dredging-free and in-situ reduction techniques to improve the substrate to eliminate blue-green algae in the water body or prevent blue-green algae outbreaks, and provide good environmental conditions for the growth of underwater animals and plants.

[0078] Specifically, the substrate improvement includes the following steps:

[0079] S211. The first ecological water diversion, mainly through drainage to reduce the water body, after meeting the requirements of about 85% of the pond area for drying ponds and drying ponds;

[0080] S212. Perform physical and chemical improvement: use silicon-calcium composite composite filler, w...

Embodiment 3

[0089] In this embodiment, the landscape pond pollutants are gradually migrated and the ecological environment of self-purification of the water body is realized by means of the governance and restoration of the ecological chain. The method includes the following steps:

[0090] S31. Substrate improvement: After the first ecological water diversion, use dredging-free and in-situ reduction techniques to improve the substrate to eliminate blue-green algae in the water body or prevent blue-green algae outbreaks, and provide good environmental conditions for the growth of underwater animals and plants.

[0091] Specifically, the substrate improvement includes the following steps:

[0092] S311. The first ecological water diversion, mainly through drainage to reduce the water body, after meeting the requirements of 90% of the pond surface to be dry and dry;

[0093] S312. Carry out physical and chemical improvement: use silicon-calcium composite composite filler, which is composed ...

Abstract

The invention discloses an SPEG biological migration small and micro water body treatment and restoration method and system. The method comprises the following steps: S1, carrying out substrate improvement, namely, carrying out desilting-free and in-situ reduction on the substrate of a water body; S2, constructing cascade aquatic plants, namely, forming an aquatic plant community through plant optimization and cascade construction; S3, constructing a three-dimensional ecological system, namely, putting aquatic animals and aquatic plants together to form a full-ecological food chain; and S4, laying an oxygen-enriched net, namely, laying a graphene oxygen-enriched net on the surface of the water body to realize water body oxygenation and targeted degradation of pollutants through natural illumination so as to construct an oxygen-enriched clear water body. According to the invention, microorganisms, aquatic plants and aquatic animal symbiotic systems play a synergistic role to form a complete water body purification enhancement system, so that 'long-term treatment and long-term clarification' of small and micro water bodies is realized, i.e., the water quality is obviously improved, the water transparency is improved, the nutritive salt is reduced, and the establishment and recovery of water body ecology are facilitated.

Description

technical field [0001] The present invention relates to the field of water body treatment, in particular to a method and system for the treatment and repair of SPEG biomigrating small and micro water bodies. Background technique [0002] With the rapid development of cities and towns in our country, the landscape and ecological functions of small and micro water bodies in many towns and rural areas are gradually lost. Direct sewage discharge, pipe network leakage, non-point source pollution, and internal source pollution are all prominent problems faced in the process of small and micro water body governance. question. Small and micro water bodies basically have no clean water supply, the water body has poor fluidity, and most of them are "dead water". [0003] In the existing technical examples, most of the treatment of small and micro water bodies adopts the method of engineering dredging to realize the transfer of endogenous pollution. On the one hand, the workload of dr...
