Abstract

The invention discloses a device for treating suspended matter in sewage through a flocculation aeration composite method and a removing method thereof. The device is composed of a purification tank support, a sewage pond, a sewage delivery device, a purification tank, an annular clear water collection channel, a clear water pipe, a discharge pipe, a sludge storage pond and a control system. The control system starts the sewage delivery device to deliver the sewage containing the suspended matter and aerobes into the purification tank from the bottom, the sewage is sequentially subjected to flocculation and aeration in the purification tank, sedimentation matter obtained after treatment is discharged into the sludge storage pond through the discharge pipe, and clear water is collected through the upper annular clear water collection channel and then discharged through the clear water pipe. According to the device for treating the suspended matter in the sewage through the flocculation aeration composite method and the removing method thereof, the structure is novel and reasonable, the removing rate of the suspended matter and the aerobes is high, and the application rage is wide.

Description

technical field [0001] The invention belongs to the field of sewage device purification, and in particular relates to a flocculation-aeration composite method for treating suspended solids in sewage and a removal method thereof. Background technique [0002] The pollution control of water environment is one of the important strategic issues of global sustainable development. Especially in my country with a large population and lack of water resources, sewage treatment is particularly important. With the continuous increase of the number of cities and towns and the total population in our country, urban sewage treatment plants, as one of the important infrastructures, will develop rapidly with the process of urbanization, so our country will become a big country that uses water treatment equipment in the world . [0003] The widespread application and development of sewage treatment equipment in my country began in the early 1990s. With the rapid development of my country's...
