Extensible combined sewage treatment system, method and application

Abstract

The invention belongs to the technical field of sewage treatment, and discloses an extensible combined sewage treatment system, method and application. A water inlet is connected with an anaerobic reaction system through a plastic pipe, and a bacterium adding device is connected with the anaerobic reaction system through a plastic ring; the anaerobic reaction system is connected with a screw pumpthrough a plastic pipe; the screw pump is connected with an aerobic aeration reaction system; the aerobic aeration reaction system is connected with the screw pump through the plastic pipe; the screwpump is connected with a dosing, disinfecting and precipitating system; the doser is connected with the dosing, disinfecting and precipitating system through a plastic pipe; the dosing, disinfecting and precipitating system is connected with the screw pump through a plastic pipe, the screw pump is connected with a secondary precipitation system through a plastic pipe, the secondary precipitation system is connected with the screw pump through a plastic pipe, the screw pump is connected with the purification treatment system through a plastic pipe, and the purification treatment system is connected with the water outlet through a plastic pipe. The screw pump is connected with a purification treatment system through a plastic pipe, and the purification treatment system is connected with a water outlet through a plastic pipe. The system is low in cost, convenient to transport, quick to install, good in mobility and convenient to operate; and automatic operation is achieved, and the working intensity of operators and resource waste are reduced.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an extensible combined sewage treatment system, method and application. Background technique [0002] At present, the closest existing technology is: the AAO sewage treatment process is composed of four processing units: anaerobic tank-anoxic tank-aerobic tank-ultrafiltration membrane separation unit, and the sewage flows through each processing unit in sequence, and the mutual Independent treatment units provide a better living environment for nitrifying bacteria, denitrifying bacteria and phosphorus accumulating bacteria in sewage biological treatment, so that better simultaneous denitrification and phosphorus removal effects can be obtained. It has been widely used in construction. However, the existing domestic sewage treatment equipment has a low treatment efficiency, a large area of ​​equipment, a low degree of integration, and a low degree of generali...
