Problems solved by technology

The final outlet of domestic sewage is generally rivers and other water bodies, but the ability of water bodies to receive sewage is limited. If the pollutants in sewage exceed the self-purification capacity of water bodies, the water bodies will no longer maintain their original shape and function, and the water body will gradually reduce. low water quality level, forming a poor water environment, causing a series of environmental pollution such as surface water, groundwater, and soil, and even endangering human health

Embodiment 1

[0029] The water environment ecological restoration system is characterized in that it includes a collection pond 1, a hydrolytic acidification pond 2, a sedimentation pond 3, and a constructed wetland 4 connected in sequence, and the constructed wetland is distributed in each household; the constructed wetland includes a fixed layer 41 , a supporting layer 42, a loam layer 43, an active medium layer 44, the fixed layer is arranged in the outermost area, the supporting layer is arranged inside the fixed layer, and the loam layer, active medium layer.

[0030] In this application, the original "distributed artificial wetland" ecological treatment system technology is proposed to treat domestic sewage, which promotes the adoption of advanced water pollution prevention and control technology by enterprises, improves the production efficiency of enterprises, and increases economic benefits; from The overall reduction of regional water pollution treatment costs has significant econ...

Embodiment 2

[0043]This embodiment provides a water environment ecological restoration system identical to that of Embodiment 1. The difference is that, further, the treatment layer includes the following components in parts by weight: 20 parts of polyacrylamide, dithiocarbamate 10 parts, 10 parts of phosphinopolycarboxylic acid, 5 parts of modified bentonite, 15 parts of bamboo charcoal-chitosan composite adsorbent, 20 parts of sodium alginate, 5 parts of lactic acid bacteria, 5 parts of actinomycetes, 6 parts of yeast, double 6 parts of Mycobacteria, 5 parts of Photosynthetic Bacteria, 5 parts of Bacillus, and 5 parts of indigenous bacteria.

[0044] The present invention combines the substrate layer with the treatment layer, so that the treatment reaction speed of domestic sewage is fast, no toxic substances are produced in the reaction process, and the ecological and resource-based treatment of domestic sewage treatment is realized, without the need to set up a sludge treatment system, ...

Embodiment 3

[0046] This embodiment provides a water environment ecological restoration system identical to that of Embodiment 1, the difference is that, further, the treatment layer includes the following components in parts by weight: 50 parts of polyacrylamide, dithiocarbamate 20 parts, 20 parts of phosphinopolycarboxylic acid, 15 parts of modified bentonite, 22 parts of bamboo charcoal-chitosan composite adsorbent, 30 parts of sodium alginate, 10 parts of lactic acid bacteria, 10 parts of actinomycetes, 12 parts of yeast, double There are 12 parts of mycobacteria, 15 parts of photosynthetic bacteria, 10 parts of bacillus, and 15 parts of indigenous bacteria.

[0047] The present invention combines the substrate layer with the treatment layer, so that the treatment reaction speed of domestic sewage is fast, no toxic substances are produced in the reaction process, and the ecological and resource-based treatment of domestic sewage treatment is realized, without the need to set up a sludge...

Abstract

The invention provides a water environment ecological restoration system which comprises a collection tank, a hydrolysis acidification tank, a sedimentation tank and constructed wetlands which are connected in sequence, and the constructed wetlands are dispersedly distributed in each family; wherein the constructed wetland comprises fixed layers, supporting layers, loam layers and active medium layers, the fixed layers are arranged in the outermost area, the supporting layers are arranged in the fixed layers, and the loam layers and the active medium layers are sequentially arranged between the supporting layers. The method is low in cost, short in technological process, low in energy consumption, good in nitrogen and phosphorus removal effect, easy and convenient to operate, maintain andmanage and low in maintenance cost, and the rural ecological landscape is increased.

Description

technical field [0001] The invention belongs to the technical field of environmental restoration, and in particular relates to a water environment ecological restoration system. Background technique [0002] With the development of urbanization and the improvement of the quality of life, the discharge of domestic sewage has also increased, further aggravating the pollution load of the waters in this area. Therefore, the implementation of domestic sewage treatment projects is an important part of protecting water quality and an objective requirement for ensuring the health of the people and the coordinated development of the economy and society. At the same time, the implementation of sewage treatment projects is an important part of the construction of ecological civilization. It has very important practical significance for accelerating the pace of urban construction. It is necessary to improve the quality of urban environment, achieve the goal of comprehensive urban envi...
