Description
Technical Field
The invention belongs to the field of water conservancy and municipal environmental protection engineering, and particularly relates to a sidewalk laying method with a dephosphorization function and a structure thereof.
Background
In recent years, the urban water environment problem caused by that the urban surface water carrying phosphorus-containing sewage is not effectively treated and directly enters urban sewers is increasingly prominent. How to effectively solve the problem becomes an important research subject for relevant personnel including environmental protection workers and water conservancy workers.
The problem of excessive phosphorus in water is one of the main research directions. The excessive phosphorus easily causes eutrophication of water body, causes enrichment of harmful microorganisms and plankton in the water body, causes pollution and deterioration of water body environment, and is easy to cause spread of human and animal diseases. Particularly, for urban drainage systems, the excessive phosphorus causes a great increase in the water treatment cost and the maintenance cost of the drainage system.
At present, in the conventional municipal construction, in order to prevent urban waterlogging and effectively utilize urban rainfall, pavement of sidewalks begins to adopt a paving form of water permeable bricks. But the water permeable bricks do not effectively intercept phosphorus pollutants in urban rainwater. Therefore, for removing urban rainfall, paving sidewalks with water permeable function and phosphorus removal function becomes an important measure for efficiently draining water in cities, fully utilizing rainfall resources and simultaneously removing phosphorus to protect the ecological environment of a water body.
Generally, municipal phosphorus-containing sewage is usually concentrated on or around sidewalks, and municipal surface water is also usually drained from the sidewalks. Therefore, it is desired to improve the sidewalk as one of the breakthrough points for solving the above problems. However, the prior art is only rarely reported to be successful in this regard.
Through search, the applicant does not find related patents of the sidewalk with the phosphorus removal function in the prior art. The related patents are generally corresponding environment-friendly sidewalk bricks, for example, the chinese patent "environment-friendly concrete sidewalk brick" with application number 201510997370.1, and such patents generally adopt environment-friendly materials as raw materials, thereby realizing a certain environment-friendly function, and failing to provide the phosphorus removal efficiency and drainage efficiency required by the above-mentioned problem of excessive phosphorus in the municipal construction process. In addition, some special sidewalk structures are designed, and a certain water storage function is given to the sidewalk, so that the polluted water can be infiltrated into a city drainage system, and the stored water can be recycled (as in the chinese patent with application number 201020676936.3), but the sidewalk cannot substantially play a role in removing phosphorus from a water body, and only slows down the infiltration degree of the polluted water.
Therefore, a pavement paving method which has high phosphorus removal efficiency and can realize rapid drainage of urban road surfaces is needed in the field.

In view of the disadvantages of the prior art, an object of the present invention is to provide a method for paving a sidewalk with a phosphorus removal function, comprising:
