大型排水构筑物的抗浮设计（Anti floating design of large drainage structures）

大型排水构筑物的抗浮设计（Anti floating design of large drainage structures） A cold rolling waste water treatment station in Wuhan is used to treat and deal with the waste water and plant sewage produced in the process line of the new cold rolled sheet plant. The main production units will produce the following three kinds of wastewater: R26; acid / alkali wastewater (A/A wastewater) R26; oily and emulsified oil wastewater (O/E wastewater) R26; chromium containing wastewater (Cr wastewater) The above wastewater is a strong corrosive waste water. In order to ensure the stable operation of wastewater treatment station, the construction of wastewater treatment station must have strong corrosion resistance. To this end, especially for wastewater treatment station building (building) building for anti-corrosion treatment. Specific anti-corrosion measures are as follows. 2 corrosion protection requirements and practices of each building (building) building and main building of the waste water treatment station 2.1, each building (construction) building material requirements of corrosion protection A: the corrosion resistance of the whole floor mortar floor (MFE-5 vinyl ester resin mortar), thickness of not less than 3 mm, around 1.2 meters below paste acid proof brick dado. B, C: floor, trench and around 1.2 meters below the paste acid proof brick dado. E area: floor with a thickness of not less than 7 mm of vinyl ester resin mortar, around 1.2 meters below the paste acid proof brick dado, thickness of not less than 3 mm of vinyl ester resin glass steel with a drainage ditch. F area: 1.5 meters below the floor and dado with a thickness of not less than 3 mm epoxy mortar. The wastewater treatment station of the working environment are wet, mild corrosive environment, other components, such as ladders, railings should have strong corrosion resistance, designed by painting chlorosulfonated polyethylene anticorrosive coatings. Vinyl glass steel pH adjusting tank, regulating pond, oily was
