反吊膜结构在污水池的使用

1、调节池部分的反吊膜应用
1. Application of reverse hanging membrane in regulating tank
通常情况下,调节池廊道较多,每个廊道尺寸又长又宽,属大跨度结构,较长的停留时间导致水中有机物、悬浮物在厌氧环境中释放出臭气,由于占地面积较大,是较大的臭气源。由于跨度较大,拱形玻璃钢盖板难以满足结构要求,若采用碳钢骨架+玻璃钢盖板的形式,则会因为骨架长期与臭气接触,在安装后的几年内就可能出现腐蚀严重的情况。故采用碳钢骨架+反吊氟碳纤维膜的反吊膜膜结构对其进行加盖密闭。
Generally, there are many corridors in the regulating tank, and each corridor is long and wide. It is a long-span structure. The long residence time leads to the release of odor from organic matter and suspended solids in the water in the anaerobic environment. Due to the large floor area, it is a large odor source. Due to the large span, the arched FRP cover plate is difficult to meet the structural requirements. If the form of carbon steel skeleton + FRP cover plate is adopted, the skeleton will be in contact with odor for a long time, and serious corrosion may occur within a few years after installation. Therefore, the reverse hanging membrane structure of carbon steel skeleton + reverse hanging fluorocarbon fiber membrane is used to cover and seal it.
采用反吊膜结构的形式对调节池进行加盖密闭,调节池各廊道间完全封闭独立,各廊道人字梁焊接在廊道间隔墙的钢立柱上,人字梁间采用连杆及弧弓连接,钢结构下设膜压板,对膜进行反吊。

The regulating tank is covered and sealed in the form of reverse hanging membrane structure. Each corridor of the regulating tank is completely closed and independent. The herringbone beams of each corridor are welded on the steel column of the partition wall between the corridors. The herringbone beams are connected by connecting rod and arc bow. The membrane pressing plate is set under the steel structure to reverse hang the membrane.

反吊膜结构的优点在于膜材自身防腐性能好,自重轻,对大跨度池体具有优势;钢结构完全放在膜外侧,既充分发挥了膜材的抗腐蚀性能,又从根本上解决了钢结构与腐蚀性气体接触带来的腐蚀问题,因此具有耐久性、安全性和经济性。
The advantages of reverse hanging membrane structure are that the membrane material has good anti-corrosion performance and light self weight, which has advantages for long-span tank body; The steel structure is completely placed outside the membrane, which not only gives full play to the corrosion resistance of the membrane material, but also fundamentally solves the corrosion problem caused by the contact between the steel structure and corrosive gas. Therefore, it has durability, safety and economy.
2、初沉池及污泥浓缩池部分
2. Primary sedimentation tank and sludge thickener
初沉池及污泥浓缩池均为圆形池体,各池有一台周边传动刮泥,均可采用碳钢骨架+反吊氟碳纤维膜的反吊膜结构形式进行加盖密闭。为避免刮泥机桥架与臭气直接接触,减少密闭体积,以刮泥机桥架为界,池体中心设置中心钢结构受力环,两侧对称布置密闭空间。两侧钢结构盖体通过中心受力环连接成一体,将刮泥机桥架暴露在集气罩以外,将原驱动系统取消,统一采用一套驱动装置对集气罩、刮泥机进行驱动,使集气罩与刮泥机同步转动。中心集电环改造后放置在桥架之上,不与臭气接触。
The primary sedimentation tank and sludge thickening tank are circular tanks. Each tank has a peripheral drive scraper, which can be covered and sealed in the form of reverse hanging membrane structure of carbon steel skeleton + reverse hanging fluorocarbon fiber membrane. In order to avoid direct contact between the sludge scraper bridge and odor and reduce the closed volume, take the sludge scraper bridge as the boundary, set the central steel structure stress ring in the center of the tank body, and arrange the closed space symmetrically on both sides. The steel structure covers on both sides are connected into a whole through the central stress ring to expose the bridge of the mud scraper outside the gas collecting hood, cancel the original driving system, and uniformly use a set of driving device to drive the gas collecting hood and mud scraper, so that the gas collecting hood and mud scraper rotate synchronously. After transformation, the central collector ring is placed on the bridge without contact with odor.
