Embodiment Construction

[0020] 1. The turntable is round, and the edge of the turntable is upturned to prevent the sludge from overflowing. A scraper is installed at the bottom of the turntable (the direction of the scraper in the odd and even layers is different), and the center of the turntable is opened to accommodate the central drive shaft and discharge downward. For sludge, set up a downpipe under the hole to avoid contact between sludge and clarified water;

[0021] 3. The multi-layer turntable unit is composed of multi-layer turntables. The odd-numbered turntables are connected to the central transmission shaft to rotate, and the even-numbered turntables are fixed on the surrounding frame of the unit. The motor and transmission device are installed on the frame of the unit to drive the central transmission shaft. ;

[0022] 4. Both advection sedimentation tank and radial flow sedimentation tank can be used. Multiple multi-layer turntable units are placed in the upper clarification area of ​​t...

Abstract

The invention relates to an improved multi-layer flat unit combined settling pond process which specially aims at urban sewage treatment and also can be used for feed water treatment and industrial wastewater treatment. The process has the most obvious characteristics that a circular settling flat plate and scrapers (scrapers on odd and even layers are different) are integrated into turntables, multiple turntables are overlapped to form units, the scrapers on the odd layers rotate (as being arranged on a central transmission shaft), the scrapers on the even layers are static (as being fixed on a frame of the units), and the settling and scraping functions are realized. The multiple units are arranged in a clarification area of the settling pond, and a settling pond mud scraper is additionally arranged in a concentration area on the lower part of the settling pond. The process has the beneficial effects that a mechanical structure of the multilayer flat unit is simplified, the operating stability is improved, the distance between the flat plates is shortened, and the number of the flat plates is increased, so that the total settling area of the settling pond is increased, the surface hydraulic loading is reduced, high-concentration activated sludge in the system is maintained, and the floor space of the settling pond is obviously saved. Moreover, the turntables can be molded at a time, and the cost is reduced.

Description

technical field [0001] The invention relates to an improved settling tank process composed of multi-layer flat plate units, which is specially aimed at urban sewage treatment, and can also be used for water supply treatment and industrial waste water treatment. Features, simplify the mechanical structure, improve work reliability, further compress the distance between the plates, and further reduce the surface hydraulic load of the sedimentation tank, which is conducive to improving the mud-water separation effect, improving the water quality of the effluent, and maintaining the high concentration of activated sludge in the system, which significantly saves the sedimentation tank The footprint is small, and the turntable can be molded at one time, reducing costs. Background technique [0002] The high-concentration activated sludge method has extremely excellent treatment capacity, but requires a sedimentation tank with low surface hydraulic load. [0003] The multi-layer p...
