Embodiment 1

[0038] A section at the connection between the inland river network and the peripheral river in a wetland is 260m long, with an average width of 41m and a water depth of 2.5-3m. Because the external rivers are seriously polluted by industrial production and life, the connected rivers become black and smelly. In order to prevent the polluted water outside the wetland from flowing into the wetland river network and further affect the water quality of the wetland water, the pollution source ecological interception technology of the present invention is adopted to intercept effective external source pollution. inflow of water. Before the treatment, the water quality test results of the peripheral connecting rivers, connecting sections, and inner rivers of the wetland are as follows:

[0039] According to the inflow of polluted water from external sources in the river and the results of water quality testing, the implementation plan for the river treatment is determined (see atta...

Embodiment 2

[0051] The difference between this example and Example 1 is that the composite microorganism is composed of 45% Rhodopseudomonas palustris, 20% Bacillus subtilis, 20% Bacillus cereus and 15% Lactobacillus casei. The compound enzyme is composed of 55% protease, 20% amylase, 15% urease and 10% cellulase.

[0052] Floating boards 5 are arranged between the adjacent ecological floating islands 3 on both sides of the river in the interception area (see attached figure 2 ), the floating plate 5 is 3m long and 3m wide, and the lower part of the center of the floating plate 5 is connected with a wire rope, and the lower end of the rope is fixedly connected with a heavy object. Hemispherical bumps, the diameter of the hemispherical bumps is 0.5-1cm, and the distribution density of the hemispherical bumps is 500-1000 per square meter; the surface of the floating plate is evenly coated with a photocatalyst, and the thickness of the photocatalyst is 4-8μm.

Abstract

The invention discloses an ecological intercepting technology of a source of pollution of urban and rural polluted water, and technology is used for solving the problem of intercepting exogenous pollution of opened polluted water and ecological repair problem of the polluted water. The technology comprises the following steps: (1) arranging two ecological intercepting walls of the source of pollution at the entrance of the source of pollution of a river along the length direction to form an intercepting area; (2) arranging ecological floating islands on both sides of the river in the intercepting area; (3) putting complex enzymes and compound microorganisms to the intercepting area so as to purify the water; (4) putting aquatic animals to the intercepting area so as to purify the water. The water quality is enhanced, the ecological environment of the water is improved, and meanwhile, the effect of optimizing landscapes is realized.

Description

technical field [0001] The invention relates to the field of water environment ecological restoration, in particular to an ecological interception technology for urban and rural polluted water pollution sources. Background technique [0002] Urban and rural open water bodies have a certain self-purification ability. As long as external pollution is well controlled, the treatment of polluted water bodies will be more effective and thorough. However, due to the current lag in the construction of urban and rural sewage pipe networks and sewage treatment facilities, it is impossible to effectively prevent various industrial sewage, agricultural sewage, and domestic sewage from being directly or indirectly discharged into rivers to spread and pollute river network water bodies. Therefore, when the pollution source is not effectively controlled, the treatment and restoration of the open polluted river water body not only seriously affects the treatment effect, but also the water q...
