Description
The technical field is as follows:
the invention relates to the technical field of environmental protection, in particular to an ecological seal cover suitable for ventilation and light transmission of a small river channel in an urban area.
Background art:
along with the rapid development of economy and the acceleration of urban modernization process, urban small rivers face more and more various ecological environment problems, which are specifically shown in that various solid wastes block the river channel, the water quality of a water body is obviously poor, the ecological environment of the wetland is deteriorated, and the ecological system of the river is increasingly seriously damaged;
the small river channel is generally a branch of a large river in a basin, has various ecological environment functions of drainage, confluence, water supply and the like, and is generally characterized by narrow river surface, short length, shallow water depth and more water;
the small river channel is closely related to the development and life of human beings, the serious water pollution problem of the small river channel can directly influence the water environment quality of the river of the imported main stream, and the distribution characteristics determine that the small river channel is closely related to the development of cities and the normal production life of people;
china is reformed and opened for nearly 40 years, urban and rural industrial and agricultural industries develop rapidly, comprehensive national force is enhanced, the living standard of people is improved, the obtained score is known to the world, but environmental problems occurring in various places touch the eyes and are surprised, water resource development far exceeds the bearing capacity of the water resource development, the investment of environmental protection is extremely limited, and therefore the serious situation of 'river existence, no water existence and water pollution' is caused. Under the background, the research on the pollution treatment and restoration technology of the small river channel is necessary;
river pollution refers to the phenomenon that the water quality of river water is deteriorated due to pollutants directly or indirectly discharged into the river;
at present, the water environment pollution of the small urban riverway is mainly divided into exogenous pollution and endogenous pollution, wherein the exogenous pollution mainly comes from point source and non-point source pollution generated by human production and activities on the edge of the urban riverway, for example, point source discharge pollutants of domestic sewage and industrial wastewater on the edge of the riverway are imported, and non-point source pollution of farmland fertilizer rain runoff and agricultural aquatic culture sewage on the edge of the riverway is imported;
the internal pollution is generally caused by the fact that the external pollution of the urban river channel is continuously input, pollutants are continuously accumulated in the river channel until the external pollution exceeds the bearing capacity and the self-purification capacity of the original water environment of the river channel, and therefore the phenomenon of damage to an original ecological balance system in the river channel is caused, specifically, the phenomenon that the river loses the digestion and purification capacity on external sewage is shown, and the pollutants accumulated previously are continuously released secondarily to bring a new pollution source;
from the pollution characteristics, the small river channel is seriously polluted by organic matters, and the chemical oxygen demand, ammonia nitrogen, total phosphorus and total nitrogen in the river water are seriously exceeded, so that a plurality of obvious symptoms of river ecosystem degradation, such as serious water body pollution, blackening and smelling water quality, excessive algae, reduced transparency, increased water temperature amplitude, reduced environmental capacity and the like, appear;
at present, the pollution problem of urban small rivers has the characteristics of complex ecological system, complete pollution types, a large number of pollution sources, serious harm and the like;
at present, the existing measures for treating the pollution problem of small and medium river channels in cities are mainly classified into three types: sewage interception and storage pipe treatment, local centralized treatment and ecological treatment;
the sewage intercepting and receiving pipe treatment refers to that a pollution source directly discharged into a small river channel is discharged into a municipal sewage pipe by a pipeline guide way, the sewage pipe enters a sewage treatment plant and is discharged into the river channel after treatment, a sewage intercepting main pipe is a main sewage pipe which is parallel to and close to a river bank side line and is used for intercepting all main pipes or branch pipes directly discharging sewage to the river in a drainage area, and the sewage flows to the sewage treatment plant along the pipe, the sewage is discharged into a water body after simple treatment, and the mode of laying the pipeline has two types: laying a sewage intercepting pipeline along the edge of the river and laying the sewage intercepting pipeline in the river channel, namely if a planned municipal road is arranged along the river, combining the sewage intercepting pipeline with the planned municipal road, otherwise laying the sewage intercepting pipeline under the current road along the river;
the method for centralized treatment in situ is to adopt a centralized collection and on-site treatment method for treating areas with temporary non-pollutant interception and receiving pipe conditions, and the treatment scheme adopted at present comprises the following steps: the ultramicro power sewage treatment technology is characterized in that the ultramicro power sewage treatment technology combines the denitrifying technology of strong membrane forming bacteria and applies the automatic release chemical phosphorus removal technology to denitrify and remove the domestic sewage on the basis of the prior sequencing batch bioreactor technology and the biological aerated filter technology, and finally realizes the discharge reaching the standard, the buried sewage treatment technology is that the sewage enters a water distribution pipe after being pretreated by a grating and a homogenizing tank, a plurality of layers of gravels, gravel, composite artificial soil and filler are paved around the sewage, the sewage slowly rises and infiltrates and diffuses into the surrounding soil through the capillary siphoning action of the gravel, unsaturated infiltration occurs in the soil layer on the ground surface, and the organic pollutants in the sewage are adsorbed and degraded through the action of aerobic and anaerobic microorganisms in the soil layer, the distributed sewage treatment equipment is an integrated and modularized high-efficiency sewage biological treatment system and mainly comprises an anaerobic biological filter and a contact oxidation tank;
the ecological treatment mainly comprises a method for planting floating plants and a method for treating a stripping solution, wherein the method for planting floating plants such as water hyacinth, big floating plants, poly grass and the like to degrade COD,TP、TN、NH4-N purifying the water quality; after the stripping liquid diluted according to a certain proportion is injected into a water body by a high-pressure pump, the blue algae and eutrophication substances in the water body are completely floated to the water surface in a short time, and then impurities are intensively fished;
through implementation, the pollution condition of a plurality of river channels is obviously improved, but the treated river channels can only be kept clean in a short time without controlling pollution sources essentially, and after a few months, natural pollution is coupled with artificial pollution, so that the water quality of the river channels is deteriorated again, and the ecological environment problem of the river channels is difficult to be cured;
in addition, in order to keep the water environment quality at a good level, only river water can be periodically pumped and changed, but the cost is extremely high, and a large amount of water resource waste can be caused;
the overall requirements of an ideal technology for treating the river water body pollution are that the water treatment agent treats both symptoms and root causes, is efficient, safe, low in cost and sustainable, and can form a perfect water ecosystem;
because the river channels of the urban river are narrow, the embankment form is hard, most of the urban river channels are in densely populated areas, the positions of both banks are limited, and unfavorable factors such as space expansion and the like do not exist, the ecological treatment work of the river channels becomes more difficult, and therefore the prior art is still to be improved and developed.
