As the urban development enters a new stage, the land value in the core district of the urban area is higher and higher, the traditional sewage treatment plant with extensive land occupies large land, the odor is dissipated, the overall perception effect is poor, and the urban high-quality development is not adapted. In recent years, construction units of newly built sewage treatment plants in many cities require full burying, sewage treatment facilities are arranged underground, and the ground surface is built as public facilities such as parks, stadiums and the like and is also used by people. The sewage treatment site is buried, the indoor damp-proof and mildew-proof problems need to be considered, and various treatment modes are basically used for preventing the mildew of basements of civil buildings (such as underground residential parks and market parks) at present.
In the practical engineering application process, the underground sewage plant is different from an underground parking lot of a civil building, various devices and regions for sewage treatment can naturally evaporate water vapor, and the indoor humidity is far higher than that of a basement of the civil building. Particularly in southern areas, the back-to-south days during the spring and summer are overlapped, the indoor water vapor concentration is very high, and the mildew prevention of the top plate and the side walls of the underground space is particularly important. Common houses and common buildings are mostly implemented according to engineering practice (05J909), and the method is mainly suitable for civil buildings and common industrial buildings, and the buildings corresponding to sewage treatment plants (the internal water vapor is sufficient and the air circulation is slow) lack of special moisture-proof and mildew-proof methods, so that the underground space structure of the internal sewage treatment plant has a mildew phenomenon.
At present, the moisture-proof and mould-proof technology for various civil buildings with higher use requirements, such as villas and market basements, mainly comprises the methods of arranging electroosmosis dehumidification on the wall surface, arranging a guide and drainage ditch on the wall surface, adding a water-proof layer, adding an inner lining wall on the inner side, adding a wall surface heating component and the like. These technologies have relatively high cost, and can be applied to commercial squares and villas to bear cost expenditure, but the sewage treatment plant station as a public infrastructure can increase the construction and long-term operation and maintenance cost.
In view of the above, the present invention is particularly proposed.
